two possible ways.
1. If the converter is modern and can operate without the battery bank, plug the converter into the kill-a-watt and turn the battery disconnect switch to the OFF position. Turn on all the loads you wish to power. Measure for 12 or 24 hours.
2. Fully charge the existing battery bank, then plug the converter into the kill-a-watt unit. Turn on all the loads you wish to power. Measure for 24 hours.
