Estimating battery requirements

To calculate the battery capacity you require, read “Estimating battery requirements” and “Battery sizing example” on page B–41, and then complete the “Battery sizing worksheet” on page B–42.

To determine how much battery capacity you need:

1.Determine how many watts are consumed by each appliance you will operate from the HI400. You can normally find this on a label 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 appliances 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 on the next page.
