BATTERY INFORMATION

1.To calculate the Ah of the battery, first determine its "reserve minutes" rating. (Deep cycle marine batteries generally have the highest reserve minute ratings). This rating typically is marked on the battery along with the "Cold Cranking Amps" (CCA) rating. Multiply the reserve minutes rating of the battery by 0.3 to determine the battery approximate Ah rating. A battery with a reserve minutes rating of 166 has an Ah rating of 49.8.

2.To estimate the maximum battery current the inverter will require to run a piece of equipment or appliance, divide its continuous load wattage requirement by 10.

The Pro-1200W watt model utilizes 50 amps of battery power to operate an appliance with a 500 watt continuous load requirement. (500W divided by 10V = 50A).

3.Conclusion: The reserve power of the battery is sufficient to satisfy the continuous load demand placed on the inverter for a maximum of about one hour. (49.8 Ah divided by 50A = 1 hour).

Note:

•When the inverter will be operating equipment or appliances with high continuous load ratings for extended periods, it is not advisable to power the inverter with the same battery used to power your vehicle. If the car or truck battery is utilized for an extended period, it is possible that the battery voltage may be drained to the point where the battery has insufficient reserve power to start the vehicle.

BATTERY/CABLE INFORMATION

•It may be advisable to operate the inverter from a bank of batteries of the same type in a "parallel" configuration. Two such batteries will generate twice the Ah of a single battery; three batteries will generate three times the Ah and so on. See “Making a Connection” on page 13 for more information.

This multiple parallel battery option is especially recommended for the Pro-2500W and Pro-3000W inverters due to the high level of amps these models require to produce up to 3000 watts of continuous load.

Wire Cable Gauges

For safe and proper operation of the inverter, connect the inverter to the power source with the proper gauge available and in the shortest length practical.

Pro-1200W and Pro-1600W

When the inverter and the battery are set up within three feet of each other, use a minimum of #4 gauge wire to make the connections. Within four to six feet, use a minimum of #2 gauge wire (Pro-1200W), #0 gauge for Pro-1600W. At distances between six feet to ten feet, use #0 gauge wire (Pro-1200W), #00 gauge for Pro-1600W.
