Estimating Battery Requirements

To determine how much battery capacity you need:

1.Determine how many watts are consumed by each appliance that you will operate from the TS400. You can normally find the watt rating labelled on the product. If only the current draw is given, multiply it by 115 to get the power consumption in watts.

2.Estimate how many hours each appliance will be operating each day.

3.Calculate the daily watt-hours needed for each appliance.

4.Add the total number of watt-hours needed for all the equipment and multiply it by the number of days between charges.

5.Divide the total watt-hours of AC load between charges by 10. This gives the battery Ah used between charges.

6.Double the total Ah used between charges to get the recommended battery size in Ah.

See the battery sizing example that follows.

Battery Sizing Example

This battery sizing example illustrates a typical calculation, assuming an opportunity to charge the batteries every three days:
