975-0560-01-01(XW-MPPT80-600_Ops).book Page 1 Wednesday, November 22, 2017 5:52 PM 1 Introduction Chapter 1 describes the features and functions of the Conext MPPT 80 600 Solar Charge Controller.
975-0560-01-01(XW-MPPT80-600_Ops).book Page 2 Wednesday, November 22, 2017 5:52 PM Introduction Features The Conext MPPT 80 600 Solar Charge Controller (charge controller), tracks the maximum power point of a PV array to deliver the maximum available current for optimum charging of batteries. The charge controller can be used with 24 VDC and 48 VDC battery systems only. The charge controller is designed to regulate the available power from a PV source only.
975-0560-01-01(XW-MPPT80-600_Ops).book Page 3 Wednesday, November 22, 2017 5:52 PM Maximum Power Point Tracking Maximum Power Point Tracking Maximum Power Point Tracking (MPPT), allows the charge controller to harvest the maximum energy available from the PV array and deliver it to the batteries. The MPPT algorithm continuously adjusts the operating voltage of the array to find the maximum power point.
975-0560-01-01(XW-MPPT80-600_Ops).book Page 4 Wednesday, November 22, 2017 5:52 PM Introduction Charge Controlling The charge controller regulates the PV array current at an appropriate level for 24 or 48 V batteries. It can produce up to 80 amps of charging current for both 2560 watts at 24 V or 4800 watts at 48 V. The charge controller can be configured to use a two-stage (no float) or threestage charging algorithm.
975-0560-01-01(XW-MPPT80-600_Ops).book Page 5 Wednesday, November 22, 2017 5:52 PM Charge Controlling The charge controller transitions to the float stage if either of the following two conditions are met: • The charge current into the batteries falls below the exit current threshold, which is equal to 2% of the programmed battery capacity (for a 500 amphour battery bank, this would be 10 amps), for one minute.
975-0560-01-01(XW-MPPT80-600_Ops).book Page 6 Wednesday, November 22, 2017 5:52 PM Introduction NOTE This notice is applicable to Figure 1-2 and Figure 1-3. • When the charge cycle is interrupted, the charge controller will resume charging at the beginning of the multi-stage algorithm. • The exit current threshold mechanism can be disabled by setting the amp-hour capacity to 0. In this case, absorption will only exit when the absorption timer expires.

975-0560-01-01(XW-MPPT80-600_Ops).book Page 8 Wednesday, November 22, 2017 5:52 PM Introduction If a BTS is not installed, the voltage settings for charging are based on one of three temperature settings (Cold, Warm, or Hot) available on the Charger Settings menu. See “Configuring Battery Characteristics and Battery Charging” on page 2–4. If there are multiple charge controllers and one or more Conext XW+ Inverter/ Chargers connected to the Xanbus network, then only one BTS is required per battery bank.
975-0560-01-01(XW-MPPT80-600_Ops).book Page 9 Wednesday, November 22, 2017 5:52 PM Auxiliary Output Functions Auxiliary Output Functions The charge controller has a set of auxiliary relay contacts—one normally opened (NO) and one normally closed (NC)—that can be used to drive a relay for load control or to turn on devices such as vent fans or indicator alarms. The auxiliary output can be configured to trigger under only one condition at a time.

975-0560-01-01(XW-MPPT80-600_Ops).book Page 14 Wednesday, November 22, 2017 5:52 PM Operation NOTICE BATTERY DAMAGE Never equalize a battery more than necessary. Equalization can damage your batteries if performed too frequently or done improperly. Always check electrolyte level before and after equalization. Fill with distilled water according to the battery manufacturer’s recommendation. The charge controller enables equalization only when the battery type is set to Flooded.
975-0560-01-01(XW-MPPT80-600_Ops).book Page 15 Wednesday, November 22, 2017 5:52 PM Equalizing Batteries The charge controller applies the equalization charge for one hour. You can stop the equalization process manually at any time by changing the setting to Disabled. The one hour equalization timer will continue to run even if there is insufficient power from the PV array to support this charge mode.

975-0560-01-01(XW-MPPT80-600_Ops).book Page 2 Wednesday, November 22, 2017 5:52 PM Boost Charging Using Boost Charging Boost charging allows for better utilization of flooded lead acid batteries under moderate cycling in off-grid applications. Boost charging encourages a short duration charging voltage—above the gassing voltage—at the beginning of the absorption charge state. Testing has shown that boost charging improves battery performance by providing a regular mixing of the liquid electrolyte.
