MMS Series Models MMS1012 - a 1000 watt inverter/charger with 20 amp AC transfer capability and a 50 amp, 4-stage Power Factor Correction (PFC) charger.
1.0 Introduction http://www.wholesalesolar.com/ How an Inverter/Charger Works An inverter takes direct current (DC) from your batteries and turns it into alternating current (AC), like you use at home. With MMS Series models, it also takes alternating current (when connected to a generator or to shore power) and transforms it into direct current to recharge your batteries.
http://www.wholesalesolar.com/ 1.0 Introduction Depending on your inverter capacity, larger electrical appliances such as coffee pots and hair dryers can be used for short durations. However, loads that are used for longer periods such as stoves or water heaters can quickly drain your batteries and are not recommended for inverter applications. All electrical appliances are rated by the amount of power they consume.

http://www.wholesalesolar.com/ 3.0 Operation 3.0 Operation Operating Modes The MMS Series inverter/charger has two normal operating routines; Inverter Mode, which powers your loads using the batteries, and Standby Mode, which transfers the incoming AC power (i.e., shore power or a generator) to power your loads and also uses this incoming power to recharge the batteries. This inverter also includes an extensive protection circuitry that shuts down the inverter under certain fault conditions.
3.0 Operation http://www.wholesalesolar.com/ Standby Mode The MMS Series features an automatic transfer relay and an internal battery charger when operating in Standby Mode. Standby Mode begins whenever AC power (shore power 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.
http://www.wholesalesolar.com/ 3.0 Operation The automatic 4-stage charging process includes: • Bulk Charging: This is the initial stage of charging. While bulk charging, the charger supplies the battery with constant current. The charger remains in bulk charge until the absorption charge voltage is achieved (14.6 VDC)* – as determined by the Battery Type selection**. • Absorb Charging: This is the second charging stage and begins after the bulk voltage has been reached.
3.0 Operation http://www.wholesalesolar.
http://www.wholesalesolar.com/ 3.0 Operation Battery Temperature Sensor Operation - The plug-in Battery Temperature Sensor (BTS) is used to determine the battery temperature around the batteries. This information allows the multi-stage battery charger to automatically adjust the battery charge voltages for optimum charging performance and longer battery life. When the BTS is installed, if the temperature around the BTS is below 77°F (25°C) the absorb and float charge voltage increases.
3.0 Operation http://www.wholesalesolar.com/ 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, then 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 conditions listed below.
http://www.wholesalesolar.com/ • 3.0 Operation Internal Fault - The inverter continually monitors several internal components and the processor communications. If a condition occurs that doesn’t allow proper internal operation, the inverter will shut down to protect itself and the connected loads. The inverter will need to be reset to start operating. Table 5, Inverter Battery Turn On/Off Levels Inverter Battery Turn On/Off Levels MMS1012 MMS1012-G HBCO >15.8 VDC >15.8 VDC HBCI 15.5 VDC 15.
3.0 Operation http://www.wholesalesolar.com/ Protection Mode There are five fault conditions that will cause the inverter to shut down: Low Battery, High Battery, Over-temperature, AC Overload, and Internal faults. If your inverter has shut down, monitor the status indicator and count the number of blinks that occur every four seconds to determine the particular reason for the shutdown. Refer to the Troubleshooting section to help diagnose/clear the fault condition.
http://www.wholesalesolar.com/ 3.0 Operation 03 Battery AmpHrs: This setting allows you to input the battery bank size in amp hours. This provides information to the charger on how long to charge the batteries in the Absorb Charging stage. 04 Battery Type: This setting identifies the type of batteries being used in the system. This provides information to the charger to determine what voltage level to use to charge the batteries.

http://www.wholesalesolar.com/ Appendix A - Optional Equipment and Accessories Appendix - Optional Equipment and Accessories The following Magnum Energy components are available for use with the MMS Series inverter/charger. Some of these items are required depending upon the intended use of the inverter. Smart Battery Combiner The Smart Battery Combiner (ME-SBCTM) is designed to monitor and charge a second battery using a portion of the current that is charging the main battery.
http://www.wholesalesolar.com/ Appendix B - Battery Information Appendix B - Battery Information Battery Bank Sizing The size of the battery bank determines how long the inverter can power the AC loads without recharging. The larger the battery bank, the longer the run time. Size your battery bank to the system’s AC load requirements and the length of time required to run the load from the batteries. In general, the battery bank should not be discharged more than 50%.
http://www.wholesalesolar.com/ Appendix B - Battery Information Parallel Wiring Wiring the batteries in parallel increases the total run time the batteries can operate the AC loads. A parallel connection combines overall battery capacity by the number of batteries in the string. Even though there are multiple batteries, the voltage remains the same. In the example below (Figure 19), four 12 VDC/100 AHr batteries are combined into a single 12 VDC/400 AHr battery bank.
