Introduction 1.0 Introduction Congratulations on your purchase of a MS Series inverter/charger from Sensata Technologies. The MS Series is a “pure” sine wave inverter designed especially for rugged mobile applications, home backup power, and standalone applications. Powerful, yet simple to use, this inverter/charger will provide you with years of trouble-free performance you have come to expect from Sensata. Installation is easy.
Introduction 1.1 How an Inverter/Charger Works There are two modes of operation associated with this inverter/charger: Inverter Mode When the inverter is properly connected to batteries and turned on, the direct current (DC) from the batteries is transformed into a pure sine wave alternating current (AC). This AC is similar to the voltage provided by your utility and is used to power any electrical appliances (i.e., AC loads) connected to the inverter’s output.
Introduction 1.3 Features and Benefits The MS Series inverter/charger is designed to allow easy access to wiring, circuit breakers, and controls. Its die cast baseplate with one-piece aluminum cover ensures maximum durability with minimum weight, as well as a cooler, more efficient operation. Note: While not pictured, the MS2000 models have the same features as those listed in this section.
Introduction 7 DC Equipment Ground Terminal – this connection is used to tie the exposed chassis of the inverter to the DC grounding system. This terminal accepts CU/AL conductors from #14 to #2 AWG (2.1 to 33.6 mm2). Tightening torque is 45 in-lb. 8 AC Entry/Exit Connections – two 3/4” knockouts provided with cable-clamp strain reliefs to accommodate and secure the AC input and output field wiring.
Introduction The left side of MS Series inverters are equipped with the following features (Figures 1-3 & 1-4): 13 Exhaust Air Vents – ventilation openings that allow heated air to be removed by the internal cooling fan. 14 Model/Serial Number Label – includes model/serial number information, date of manufacture, and inverter and charger specifications.

Installation 2.3 Wiring the Inverter – General Requirements This section describes the requirements and recommendations for wiring the MS Series inverter/ charger. Before wiring the MS Series inverter/charger, carefully read all instructions. Wiring should meet all local codes and standards and be performed by qualified personnel such as a licensed electrician.
Installation 2.4 DC Wiring This section describes the inverter’s required DC wire sizes, the recommended disconnect/ overcurrent protection, and how to make the DC connections to the inverter and the battery bank. Refer to Figure 2-6 when connecting the DC wires. WARNING: Even though DC voltage is “low voltage”, significant hazards may be present, particularly from short circuits of the battery system.
Installation MS Series Inverter/Charger (front view) BTS BTS Inverter’s DC Negative Busbar Inverter’s DC Positive Busbar Inverter’s Equipment Ground Wire Battery Temp Sensor Cable* MMP enclosure – for single inverter installations (includes DC disconnect breaker, DC shunt for battery monitor, and inverter DC busbars). If multiple inverters will be installed, see the MP enclosures - designed to allow up to four inverters to be connected together.
Installation 2.4.1 DC Wire Sizing It is important to use the correct sized DC wire to achieve maximum efficiency from the system and to reduce fire hazards associated with overheating. Always keep your wire runs as short as practical to prevent low voltage shutdowns and to keep the DC breaker from nuisance tripping (or open fuses) because of increased current draw. See Table 2-1 to select the minimum DC wire size (and corresponding overcurrent device) required based on your inverter model.
Installation If a fuse is used as an overcurrent device, a Class-T type or equivalent is recommended. This fuse type is rated for DC operation, can handle high short-circuit currents, and has a time delay that allows for momentary current surges from the inverter without opening the fuse. However, because the fuse can be energized from both directions, the NEC requires that it be installed in a manner that the power must be disconnected on both ends of the fuse before servicing.
Installation nut split washer CAUTION: Ensure nothing is placed between the cable ring lug and battery post. battery cable (with ring lug) battery post Figure 2-7, Battery Hardware Installation 2.4.4 CAUTION: Ensure nothing is placed between the DC terminal and ring lug.
Installation 2.4.5 Battery Temperature Sensor Installation and Wiring The Battery Temperature Sensor (shown in Figure 2-9) provides the inverter with precise battery temperature information to automatically adjust the ABSORB and FLOAT charge voltage set-points. This allows the batteries to be correctly charged under extreme temperature changes. If the temperature sensor is NOT installed and the batteries are subjected to large temperature changes, the battery life may be shortened.
Installation 2.4.6 Wiring the Inverter to the Battery Bank CAUTION: The inverter is NOT reverse polarity protected—if this happens the inverter will be damaged and will not be covered under warranty. Before connecting the DC wires from the batteries to the inverter, verify the correct battery voltage and polarity using a voltmeter. If the positive terminal of the battery is connected to the negative terminal of the inverter and vice versa, severe damage will result.
Installation 2.5 AC Wiring This section provides information on how to make the AC connections to the inverter using the correct AC wire size and corresponding overcurrent protection. See Figures 2-11 through 2-17. 2.5.1 Pre-AC Wiring Requirements CAUTION: Before installing any AC wiring, review the safety information at the beginning of this manual and the following to ensure a safe and long-lived system: • Always use properly rated circuit breakers.
Installation 2.5.3 Recommended GFCI (Ground Fault Circuit Interruption) Outlets In compliance with UL standards, Sensata tested the following series of GFCIs and found that they function properly when connected to the inverter’s AC output: • Hubbel #GF520EMBKA • • Leviton 8899-A, N7899, GFNT1, or GNNT2 Cooper VGF15W WARNING: Risk of electrical shock. Use only ground-fault circuit interrupters [receptacle(s) or circuit breaker(s)] compatible with your MS inverter/charger.
Installation 2.5.5 AC Conductor Wiring (MS2012, MS2812, MS2024, MS4024, & MS4048) The following steps are basic guidelines for installing and connecting the AC wiring to and from all MS Series inverters (except MS2000 Series model inverters—for instructions on wiring MS2000 Series model inverters, refer to Section 2.5.7). Before proceeding, refer to Table 2-3 to determine your AC wiring configurations.
Installation 2.5.6 AC Wiring Configurations (MS2012, MS2812, MS2024, MS4024, & MS4048) The following table provides the different wiring configurations for installing and connecting the AC conductors to and from the inverter (refer to Figures 2-11 to 2-15 for installation drawings showing these configurations).

Installation 2.6 Grounding Inverters The inverter/charger should always be connected to a permanent, grounded wiring system. An inverter system that is properly grounded will limit the risk of electrical shock, reduce radio frequency noise from the inverter, and minimize excessive surge voltages induced by lightning. This is done by ensuring there is a well-defined, very low-resistance path from the electrical system to the grounding system.
Installation 2.6.1 Sizing the Grounding Electrode Conductors AC Side – The size of the AC grounding electrode conductor (GEC – AC) depends on the size of the largest ungrounded conductor feeding the AC load center. One #8 AWG (8.4 mm2) copper conductor will serve as an AC grounding electrode conductor (GEC – AC) for AC power conductors smaller than and including #2 AWG (33.6 mm2) copper. See Table 2-5 for additional values.
Installation Method 2 (Figure 2-20): When the AC and DC service panels are near each other, then the AC grounding electrode conductor (GEC – AC) and DC grounding electrode conductor (GEC – DC) can be connected to a single grounding electrode. In this method—since there are multiple connections to the DC grounding electrode (GEC – DC)—the size of the DC grounding electrode conductor cannot be smaller than the largest conductor in the DC system (usually the battery-to-inverter cable).
Installation 2.6.2 System Bonding Jumper The MS Series inverter does not include an internal bond between the grounded conductor (AC neutral/DC negative) and the equipment grounding terminals. This bond [system bonding jumper (SBJ)] is usually done in the main distribution panel for each electrical system. CAUTION: There should be one and only one point in each electrical system (both AC and DC) where the grounded conductor is attached to the grounding electrode conductor.
Installation 2.6.4 Grounding on Boats When installing the MS Series inverter/charger on a boat, there are several considerations that must be followed when grounding to ensure a safe installation, prevent galvanic corrosion, and to adhere to ABYC (American Boat and Yacht Council) standards. Ensure a Safe Ground Connection When AC on the boat is being supplied by shorepower, the onboard neutral should be connected to safety ground on the dock1.
Installation 2.6.5 Neutral to Safety Ground Bonding The standards for safely wiring residential, commercial, RV/truck, and marine installations in the United States require the neutral and safety ground to be connected at the AC source; whether it is the utility feed in your home, an inverter, or a generator. This is to establish a specification that maximizes the possibility that a circuit breaker will activate if a hot wire-to-ground fault occurs.
Installation 2.6.6 Disabling the Neutral-to-Ground Connection All MS Series inverter/chargers have the automatic neutral-to-ground switching feature. In some installations/jurisdictions, this feature must be disabled by disconnecting the neutral-to-ground connection¹. If you are not sure whether you must disable this feature, check your local code requirements. The following steps will guide you in disabling the neutral-to-ground switching feature.
Installation 2.7 Inverter Notification Requirements When an inverter is installed in a building, facility or structure, the NEC (National Electrical Code) requires a label or plaque to be provided. This label/plaque is required to be easily visible and provide information that informs personnel on the location of all electrical system disconnects. This is to ensure all power to a building is quickly located and shut down in an emergency.
Installation 2.9 Functional Test After all electrical connections to the inverter, batteries, AC source and sub-panel have been completed, follow these steps to test the installation and the inverter’s operation. CAUTION: Use a multimeter to verify the correct DC voltage for your particular inverter model (i.e.

Operation 3.0 Operation The MS Series inverter has two normal operating routines: Inverter mode, which powers your loads using the batteries, and Standby mode, which transfers the incoming AC current (i.e., utility power or a generator) to power your loads and to recharge the batteries. This inverter also includes an extensive protection circuitry to shut down the inverter under certain fault conditions. 3.1 Inverter Mode When the MS Series is first powered up, it defaults to the OFF mode.

Operation 3.2 Standby Mode The MS Series features an internal battery charger and an automatic transfer relay when operating in Standby mode. Standby mode begins whenever AC power (utility or generator) is connected to the inverter’s AC input. Once the AC voltage and frequency of the incoming AC power is within the AC input limits, an automatic AC transfer relay is activated. This transfer relay passes the incoming AC power through the inverter to power the AC loads on the inverter’s output.

Operation The Charge mode provides up to four separate charging stages: Bulk Charging, Absorb Charging, Float Charging and Full Charge (Figure 3-7). Bulk Charging: This is the initial stage of charging. While bulk charging, the charger supplies the battery with controlled constant current. The charger remains in bulk charge until the absorption charge voltage (determined by the Battery Type selection*) is achieved. The inverter’s green LED stays ON (solid) to indicate bulk charging.
Operation 3.4 Transfer Time While in Standby mode, the AC input is continually monitored. Whenever AC power falls below the VAC dropout voltage (80 VAC, default setting), the inverter automatically transfers back to Inverter mode with minimum interruption to your appliances—as long as the inverter is turned on. The transfer from Standby mode to Inverter mode occurs in approximately 16 milliseconds.
Operation 3.6 Protection Circuitry Operation The inverter is protected against fault conditions and in normal usage it will be rare to see any. However, if a condition occurs that is outside the inverter’s normal operating parameters, it will shut down and attempt to protect itself, the battery bank, and your AC loads. If there is a condition that causes the inverter to shut down, it may be one of the following conditions [also refer to the Troubleshooting section (Section 4.
Operation 3.7 Inverter Startup Power ON/OFF Switch – The inverter can be turned on and off by lightly pressing and releasing the Power ON/OFF switch on the front of the inverter (Figure 3-9). When the inverter is first connected to the batteries, or when its automatic protection circuit has turned the inverter off, the ON/OFF switch will need to be pressed to start the unit (or reset per Section 4.4).
Operation 3.8 Factory Default Values Your MS Series inverter/charger uses default values for the adjustable settings (Table 3-2) that are adequate for most installations. If some of your operating parameters need to be changed from the default values, an optional remote control can be used to make those changes. To help you determine if you need a remote display, information on the inverter/charger settings that can be changed is provided below.
Operation 3.9 Inverter Fan Operation The inverter contains two internal cooling fans that are automatically controlled. The speed of these fans is determined either by the internal temperature of the inverter or by the load on the inverter. The inverter’s fans will come on under the conditions listed below: • Fans run full speed if the internal transistors (FETS) or the power transformer reaches 80°C degrees Celsius (176°F), or the inverter is running at 100% of its rated load.
Maintenance and Troubleshooting 4.0 Maintenance and Troubleshooting The following information is provided to help you keep your MS Series inverter/charger in optimum operational condition. 4.1 Recommended Inverter and Battery Care The MS Series inverter/charger is designed to provide you with years of trouble-free service.
Maintenance and Troubleshooting 4.3 Troubleshooting The MS Series inverter/charger is a fairly simple device to troubleshoot. The following chart is designed to help you quickly pinpoint the most common inverter failures. Table 4-1, Basic Troubleshooting Symptom No output power. Inverter LED is OFF Possible Cause Recommended Solution Inverter is switched OFF Switch the inverter ON. Battery voltage is too low.
Maintenance and Troubleshooting 4.4 Resetting the Inverter Under some fault conditions (e.g., an internal fault), the inverter will need to be reset. Ensure all AC power (utility, generator, shorepower) is removed from the inverter’s input before resetting. CAUTION: If AC is connected while performing an inverter reset, damage may occur. 4.4.1 Performing an Inverter Reset To perform an inverter reset (also known as a “soft reset”): 1.

If the inverter is capable of producing more amperage than the locked rotor amps rating of a motor, it will most likely start the motor easily.
