1 Introduction Chapter 1, “Introduction”, describes the operational features of the Conext XW+ Inverter/Charger.
Introduction Features The Conext XW+ is a modular building block sine-wave inverter/charger that can be used for residential and commercial battery based off-grid, grid backup, and grid interactive applications. The Conext XW+ is a self-contained DC to AC inverter, battery charger, and integrated AC transfer switch. It is configurable in a hybrid system to operate with generators and renewable energy sources. These configurations are capable of extending battery based off-grid/backup autonomy.

Introduction The Conext XW+ has an internal automatic transfer switch (K1, K2) which allows either AC1 or AC2 to be connected to the inverter input, but not both at the same time (See Figure 1-1, “Connection Points and Major Power Conversion Components of Conext XW+ ” on page 1–4). This allows shared AC energy during charging or to directly pass through from AC1, or AC2, to AC Out.

Operation Surge Performance Unlike many other inverters, the Conext XW+ helps stop voltage from sagging dramatically during surge conditions. The Conext XW+ handles surges of over twice its rated output power with only a minimal drop in output voltage for limited periods of time. Islanding Protection Islanding protection is an essential safety feature that helps reduce harm to those working on the utility grid from a distributed energy source such as the Conext XW+.
In addition to the information panel, the Conext System Control Panel indicates a utility fault with the Fault light and also displays a fault message on screen (faults F23 to F40 are utility faults—see Figure 4-6, “Fault Messages” on page 4–19). The fault cannot be manually cleared. Utility faults will clear automatically when the utility grid voltage and frequency return to within the ranges programmed into the Conext XW+.
Operation Consult the manufacturer's specifications to determine if your PV inverter is compatible with Active Frequency Shift Power Curtailment. Conext XW+ AC coupling function is enabled by default (Advanced Features Menu). NOTICE AC COUPLED PV INVERTER COMPATIBILITY AC power generated by AC coupling PV inverters with Conext XW+ must be consumed by AC loads or used to charge batteries. As an alternative, the excess power produced from a PV inverter can be routed to dump loads.
Introduction Parallel Charging Multiple Conext XW+ units on the same Xanbus network synchronize their charging stages to help provide efficient charging of the battery bank. When a single unit transitions from bulk to absorption, so do all other units. In absorption, all units must complete the absorption stage before any of them transition to the next stage. Note that units stop sharing charge current just before completing the bulk stage and only share charging load during the bulk stage.
Operation Auxiliary Output Each Conext XW+ has one programmable 12 V, 0.25 A auxiliary output that is able to run a small fan or operate an external relay to perform other functions. Examples include remotely starting a two-wire start generator in cases where the Xanbus-enabled Conext AGS is not used, disconnecting external non-critical loads, or turning on a diversion load for battery voltage regulation. See “Auxiliary Output Settings” on page 3– 34 for programme parameters.
Introduction Monitoring the Conext XW+ Operation of the Conext XW+ can be monitored using the factory-installed inverter information panel or the optional Conext System Control Panel and ComBox. To configure the Conext XW+, the Conext System Control Panel or ComBox must be used. Conext XW+ Information Panel The Conext XW+ information panel features: • Buttons for Conext XW+ Startup/Shutdown/Standby control, clearing faults and warnings, and battery equalization.
Monitoring the Conext XW+ Conext System Control Panel The Conext System Control Panel (Conext SCP) or Conext ComBox is required for configuring the Conext XW+ and other Xanbus-enabled system components. The Conext SCP features: • A liquid crystal display which provides graphics and text describing real time operation and status information. • LED event and warning indicator. • Internal clock which is used to control time-dependent Conext XW+ functions.
Introduction 1–14 975-0240-01-01
2 Monitoring Operation Chapter 2, “Monitoring Operation”, contains information about monitoring Conext XW+ Inverter/Charger operation using the inverter information panel or the Conext System Control Panel.
Monitoring Operation Monitoring Operation with the Inverter Information Panel The inverter information panel on each Conext XW+ monitors a single Conext XW+. The Conext XW+ information panel displays basic information and performs start up, shut down, equalization and standby functions. LEDs on the information panel indicate AC input status, Conext XW+ status, battery condition, and charging and equalization status.
Monitoring Operation with the Inverter Information Panel When one AC input LED is on and the other AC input LED is flashing, AC input is present on both AC1 and AC2. However, the Conext XW+ can qualify and receive AC input from only one source at a time. The qualified source is represented by the steadily lit LED. When two sources of AC input are present, the Conext XW+ uses the source selected under AC Priority in the AC Settings menu.
Monitoring Operation Monitoring Charger Status The green LED labelled “A” indicates the Conext XW+ is charging the battery bank. When this LED is on, the numeric display screen shows battery charging current in amps. Symbol LED On LED Flashing LED Off The Conext XW+ is charging the battery bank. The numeric display screen shows battery charging current in amps. AC coupled charging is occurringa. The Conext XW+ is not in charge mode.
Monitoring Operation with the Inverter Information Panel Symbol LED On LED Flashing The Conext XW+ has a fault and has stopped charging or inverting. The LED also turns on steadily if the unit has both a fault and a warning. The Conext XW+ has a warning. A warning may escalate to a fault if the warning condition does not go away. Equalizing Batteries Button Pressing the Equalize button ( symbol) for five seconds initiates a battery equalization cycle.
Monitoring Operation Note: In a system where more than one device is capable of equalizing batteries (such as a system including multiple Conext XW+ units and/or Conext Solar Charge Controllers), there is no system-wide equalization command for all devices. To equalize with multiple devices, each would have to be enabled individually. Alternatively, equalization can be performed using only the selected device.
Monitoring Operation with the Inverter Information Panel If the STARTUP/SHUTDOWN button is pressed and held on a Conext XW+ and a Conext AGS is installed in the system, the unit stops inverting or charging immediately and shuts down completely in 120 seconds. During this time, the display shows OFF. This interval allows the Conext AGS to stop the generator after a cool down period.
Monitoring Operation Figure 2-3 Battery Level LEDs Reading the Display Screen The numeric display screen shows the following information about the operational state of the Conext XW+: 2–8 • Output power in kilowatts (when the (kW) LED is lit). • Battery charger current in Amps (when the • Stb when the Conext XW+ is in Standby mode. • Sch when the Conext XW+ is in Search mode. See “Using Search Mode” on page 3–9. • OFF when the STARTUP/SHUTDOWN button is pressed and held for five seconds.
Monitoring Operation with the Conext SCP Monitoring Operation with the Conext SCP The Conext System Control Panel (Conext SCP) provides remote configuration and monitoring capability for the Conext XW+ and all other Xanbus-enabled devices in the network. You can monitor Conext XW+ operation on the Conext SCP using the: • System Status screen (see page 2–13) • Conext XW+ Home screen (see page 2–13) • Conext XW+ Meters Menu (see page 2–16).
Monitoring Operation Using the Standby Button The Standby button has two functions. The Standby button can disable inverting and charging for the Conext XW+ units in the system or when pressed simultaneously with the Exit button, can put the entire system into Standby mode. Pressing the Standby button produces the same result as disabling Invert and AC Charge in the System Settings menu.

Configuration Inverter Settings Menu The Inverter Settings menu contains settings that control when the Conext XW+ starts and stops producing AC output. Table 3-2 Inverter Settings Menu Item Description Low Batt Cut Out Low Batt Cut Out controls when the inverter stops producing AC output due to a low battery voltage condition. The inverter will stop producing AC output only after this level has been reached for the period of time set by the LBCO Delay. This setting is not temperature compensated.
Inverter Settings Menu Using the Low Battery Cut Out and LBCO Delay Settings WARNING ADVANCED CONFIGURATION HAZARD Advanced menu settings should be used by qualified personnel only. Three phase operation should be configured by qualified personnel only. Consult with the local utility before enabling Conext XW+ sell mode or grid support functions. Do not change these settings unless you are under the supervision and direction of qualified personnel.
Configuration Single units When a single Conext XW+ has search mode enabled, the inverter sends electrical search pulses through its AC output. These search pulses look for connected AC loads. The delay between search pulses is set using the Search Delay setting. After a load larger than the Search Watts setting is detected, the inverter starts producing AC output.
Charger Settings Menu Charger Settings Menu The Charger Settings menu provides options for configuring the Conext XW+ to operate from your battery bank. Table 3-3 Charger Settings Menu Item Description Batt Type Sets the system battery chemistry and type: Flooded (default), AGM, Gel, Lithium Ion, and Custom. Selecting Custom displays the Custom Settings item, which allows you to adjust the settings for each charging stage.
Configuration For default settings, see “Charger Menu” on page B–3. Battery Charger Functions When AC power is available, the Conext XW+ can operate as a battery charger. Different battery types and chemistries require different charging voltage levels. Not charging batteries at the required levels can shorten battery life or damage the batteries. The Conext XW+ is configured at the factory to work with the battery types recommended for inverter applications.
Charger Settings Menu Notes: When the charge cycle is interrupted, the charger will restart charging at the beginning of the multi-stage algorithm. Exit Current Threshold can be effectively disabled by programming the amp-hour capacity to 0. In this case, absorption will only exit once the Max Absorption timer expires. Charge current during equalize state (optional state not shown here) is normally limited to 10% of the programmed amp-hour capacity setting.
Configuration Note: If there are DC loads on the batteries, the charger’s current may not decrease to a level to transition to the next stage of charging. In this case, the charger stays in absorption until the Absorb Time setting is reached. To avoid having the charger remain in absorption for too long, adjust Absorb Time on the Charger Settings menu.
Charger Settings Menu Float Stage Float charge maintains the batteries slightly above the self discharge voltage of the batteries. The charge current in float is the current necessary to maintain the batteries at the Float Voltage setting, limited only by the inverter's capability or other settings that limit the inverter's maximum charge rate. Float charging reduces battery gassing, minimizes watering requirements (for flooded batteries), and helps the batteries remain in a constant state of readiness.
Configuration Bulk Stage Battery Voltage Absorption Stage (Boost Stage) Absorption Voltage 2-Stage Charge Custom Charge Recharge Voltage Return to Bulk Stage Boost Timer 1hr fixed Time Max Absorb Time - Dflt 3 hrs (adjustable 1 min - 8 hrs ) Battery Current Max Charge Rate Absorption Exit Current Threshold = 2% of programmed AH capacity Time Figure 3-5 Two-Stage Charging Cycle 3–16 975-0240-01-01
Charger Settings Menu Note: When the charge cycle is interrupted, the charger will restart charging at the beginning of the multi-stage algorithm. Exit Current Threshold can be effectively disabled by programming the amp-hour capacity to 0. In this case, absorption will only exit once the Max Absorption timer expires. Charge current during equalize state (optional state not shown in graph) is normally limited to 10% of the programmed amp-hour capacity setting.
Configuration After absorption, the maximum charge DC current is set to 10% of battery capacity (for example, 44 A for 440 Ah). See Figure 3-6. This constant current charge will continue until the voltage has increased to the equalize voltage at which point the battery will be regulated at the temperature compensated equalize voltage.
Charger Settings Menu If the Conext XW+ will not perform the equalization, see Warning W96 “Cannot Equalize” in Table 4-3 on page 4–12. WARNING EQUALIZATION HAZARD Only flooded lead acid batteries should be equalize charged. Hydrogen and oxygen gases are produced when batteries are equalized and can potentially cause an explosion if ignited. Corrosive battery acid can escape.
Configuration Custom Battery Settings Menu NOTICE BATTERY TYPE AND SETUP HAZARD To avoid damaging your batteries during charging or equalization, consult your battery manufacturer and associated documentation before setting a custom battery type. Failure to follow these instructions can result in equipment damage. WARNING ADVANCED CONFIGURATION HAZARD Advanced menu settings should be used by qualified personnel only. Three phase operation should be configured by qualified personnel only.
Charger Settings Menu Table 3-4 Custom Battery Settings Menu Item Description Batt Temp Comp Battery temperature compensation for a custom battery type. This setting is the reference that the BTS uses to adjust the charging voltage when the temperature is above or below 25 °C (77 °F).
Configuration AC Input Settings WARNING ADVANCED CONFIGURATION HAZARD Advanced menu settings should be used by qualified personnel only. Three phase operation should be configured by qualified personnel only. Consult with the local utility before enabling Conext XW+ sell mode or grid support functions. Do not change these settings unless you are under the supervision and direction of qualified personnel. Failure to follow these instructions can result in death or serious injury.
Grid Support Settings Table 3-5 AC Settings Menu Item Description AC1 Breaker Sets the AC1 (Grid) breaker size, based on the size of the breaker installed upstream from the AC1 connection port. The installed breaker size must not exceed the capacity of the upstream distribution panel. The Conext XW+ limits the maximum current draw on AC1 by derating its charging current to an equivalent of 80% of the AC1 breaker setting.
Configuration Note: Grid support and sell functions are modes of operation that are subject to local and/or national grid interconnection requirements in most jurisdictions. It is the responsibility of the installer and system operator to ensure that all applicable procedures and technical requirements are complied with before turning on either of these modes. Note: Upon startup, the Conext XW+ does not enable grid support functions for five minutes (300 seconds).
Grid Support Settings Table 3-6 Grid Support Settings Menu Item Description Grid Supp Volts Sets the level to which the batteries will be discharged when the inverter is selling power to the grid or supporting the power grid by providing additional power to the loads on AC Out. This setting is not adjusted for the battery temperature even if the temperature sensor is installed. Sell Turns sell mode on and off.
Configuration Table 3-6 Grid Support Settings Menu Item Description Load Shave Amps Sets the maximum amount of current that can be drawn from the AC1 (grid) input by the loads and battery charger combined. This setting determines the amperage level at which the inverter starts drawing power from the batteries to add to the utility power to meet the demand of the loads.
Prioritizing and Managing Energy Sources with Advanced Features Prioritizing and Managing Energy Sources with Advanced Features The Conext XW+ can be programmed to control how and when to use utility power as well as external DC sources of energy such as batteries and solar charge controllers. Advanced features allow management of peak loads, time-ofuse billing and self consumption. Grid Support WARNING ADVANCED CONFIGURATION HAZARD Advanced menu settings should be used by qualified personnel only.
Configuration Grid Support enabled, Sell enabled In this mode, all available excess DC power is first used to power local AC loads attached to the inverter output. Any remaining power (up to the Max Sell Amps setting) is exported to the utility grid (AC1). A battery bank rated at least 440 Ah is recommended for best sell performance. Sell Block The sell block feature halts the export of energy to the grid connected to AC1 for a period of time each day.
Prioritizing and Managing Energy Sources with Advanced Features In an enhanced grid support set up the Conext XW+ automatically tracks the Conext MPPT Solar Charge Controller voltage as it transitions through charge states (from bulk to absorption to float). This allows the system to execute a complete battery charge cycle while still converting excess DC power to AC power to support the AC loads or be exported to the utility grid.
Configuration electricity, it is preferable to use utility power for charging only during non-peak hours. Charger block can prevent utility power from being used for battery charging during peak billing periods. During the time period set between Chg Block Start and Chg Block Stop, AC1 (Grid) input continues to be passed through to the loads. Inverter operation remains unaffected during the charger block period.
Prioritizing and Managing Energy Sources with Advanced Features When the Time in Float is different than zero, PLS shall start only if the battery amperage remained at the specified level for the configured time. Example: Load Shave=Enabled, LoadShaveAmps=10 A, LoadShaveStart=6:00pm, LoadShaveStart=9:00pm, Time in Float=60 min, PLS Dly 2h= Enabled.

4 Troubleshooting Chapter 4, “Troubleshooting”, contains information and procedures for identifying and solving possible problems with the Conext XW+ Inverter/Charger.
Troubleshooting General Troubleshooting Guidelines This section will help you narrow down the source of any problem you may encounter. Please read the following troubleshooting steps: 1. Check for a Warning or Fault message on the Conext System Control Panel or a Fault code on the inverter information panel. If a message is displayed, record it immediately. 2. As soon as possible, create a detailed record of the conditions at the time the problem occurred.
Inverter Applications Inverter Applications The Conext XW+ performs differently depending on the AC loads connected to it. If you are having problems with any of your loads, read this section. Resistive Loads Resistive loads are the easiest and most efficient to drive. Voltage and current are in phase, which means they are in step with one another. Resistive loads generate heat in order to accomplish their tasks. Toasters, coffee pots, and incandescent lights are typical resistive loads.
Troubleshooting Clocks You may notice that your clocks are not accurate. Some of the clocks on your appliances may reset when the Conext XW+ is in search mode. Disabling search mode will resolve this issue (See “Using Search Mode” on page 3–9). Searching When the inverter is in search mode, it may fail to start some loads even though the rated wattage on the load is more than the Search Watts setting. Disable search or apply an additional load (companion load) to make the inverter exit search mode.
Inverter Troubleshooting Problem Possible cause Solution(s) No AC power output. Open AC output breakers or fuses and bad output wire connections. Check the Load AC Voltage status on the SCP Meters screen and check AC voltage on the inverter AC Out terminal block. The inverter information panel displays Sch. Inverter is disabled. Re-enable inverter.
Troubleshooting Problem Possible cause Solution(s) Inverter goes into invert mode and starts producing AC output and then stops or does not start at all. Search Watts setting is too low or high. Potential problem loads for search mode: If the search sensitivity is set higher than the combined loads, then connect an auxiliary load to bring the inverter out of search mode before the appliances can be turned on.
Battery Charger Troubleshooting Battery Charger Troubleshooting To determine the cause of a charger error condition, refer to the troubleshooting solutions below to resolve the situation. Problem Possible Cause Solution AC1/AC2 LED is on, but will not start charging (allow 40 seconds to synchronize). 1) Charger is disabled on the Setup menu. 1) Enable the charger. 2) Charger Block is enabled and the Conext XW+ is inside of the charger block time window.
Troubleshooting Problem Possible Cause AC1 or AC2 LED is flashing, but will not start charging AC voltage and frequency at the AC input terminal are within nominal range, but the inverter output is not yet synchronized to the AC source. There are four possible causes: (allow 40 seconds to synchronize). 4–8 Solution 1) The inverter may already be synchronized to another AC source. 1) The inverter is operating normally.
Battery Charger Troubleshooting Problem Possible Cause Solution Charger amperage drops off before full charging has finished (no Fault LED). AC frequency at the AC input terminal may be out-of-tolerance (too high or low) or the AC voltage may be outside the Hi AC Volt or Lo AC Volt settings. AC input voltage approaching the low disconnect level. Check the settings on the AC Settings menu. Check for the correct AC voltage or frequency at the AC input terminal.
Troubleshooting Problem Possible Cause Solution Charger output is low. Loose or corroded battery connections. Check and clean all connections. Loose AC input connections. Check and tighten AC wiring connections. Worn out batteries. Replace batteries. Battery cables too small or too long. Refer to cable and battery recommendations in the Conext XW+ Installation Guide. If a BTS (Battery Temperature Sensor) is installed, it may be in a cold area or have fallen off the batteries. Inspect the BTS.
Faults and Warnings Warning Messages Warning messages appear on the Conext SCP to alert you to an impending system change. You can view the 20 most recent warning messages using the Conext SCP’s warning log, accessible from the View Device Info menu. Each warning has a time stamp to let you know the date and time that the warning appeared. If several warning messages occur before you can acknowledge or clear them, they are displayed together on a warning list.
