DC Side Connection Requirements

WARNING
The ROARBATT pure sine wave inverters are suitable for 12V battery bank systems only. not following the minimum DC requirement will cause irreversible damage to the unit.
CAUTION
Be careful of the positive and negative poles. Reversing the poles might cause permanent damage to the inverter. It will surely blow the internal fuse.
NOTE
The input terminals of the inverters have large capacitors connected to them.Once a positive and negative wire are connected to the terminals, it will complete the circuit , and commence drawing a heavy current momentarily.As a result, there may be a sparking occurring even if the inverter is in the off position. To minimize sparking, it is recommended that the user have the appropriate size wire feeding into the inverters and/or install an external fuse leading into the inverter.

Battery Bank Requirements

The battery is for supplying DC input voltage to the inverter. Its rated voltage should be the same as the rated input voltage of the ROARBATT inverter.Any voltage that exceeds the input voltage range of the inverter will cause the inverter to be overloaded and may damage the inverter.
The battery ought to supply enough current for the load.(The load i s the amperage or wattage rating of the equipment being powered by the inverter.) Asmall capacity battery cannot supply enough power for large electrical equipment and it will cause the inverter to be under-voltage.

The battery ought to supply enough current for the load.(The load is the amperage or wattage rating of the equipment being powered by the inverter.) Asmall capacity battery cannot supply enough power for large electrical equipment and it will cause the inverter to be under-voltage.

SIMPLE METHOD
For determining the required battery capacity size is shown below for reference:

1. Determine the Watts (Amps * Volts) of the load
   (Each appliance has technical specifications indicating the wattage o r voltage and amperage required for operation.)

2. Utilize the formula Amps=Watts/ Volts

3. Inverter consumption=Amps*10%
   (Due to inverter efficiency 90% ,the recommended estimate for the calculation is 10%)

4. Estimated load runtime
   (The capacity of the battery depends on the load wattage and runtime. Most loads are not constant, so estimation i s essential.)

5. Determine Ah(Ampere-Hour) of the battery
   (Amps + consumption) * hours = recommended battery capacity

Grounding Requirements

The ROARBATT Pure Sine Wave inverters come equipped with a ground terminal to appropriately ground to earth or to another designated ground. (for example, a metal frame of an RV).
The connections to ground must be tight and against bare metal. Whether using the inverter ina mobile application, such as an RV, or in a building, grounding is highly recommended.
RECOMMENDATION
The recommended wire size for grounding is 14AWG or larger insulated copper strand wire.
For more information regarding grounding, users and/or installers must consult with the Local and National Electric Codes(NEC) for more specific grounding regulations and suggestions as they can change per scenario.
