Saransh NinaweHello Victoria,
Please provide complete information about load
- Assuming that your overall load requires 120VAC, 1000Amps
then, 1. 120(3*40) batteries of 100Ah rating will provide 12Hrs of backup
- Assuming that your overall load requires 120VAC, 1000Amps
then, 124(2*62) batteries of 120Ah rating will provide 15 Hrs(apx.) of backup
Its totally depends on load.
This are in ideal conditions. But in practice their will some factors that reduces the battery backup.
If you want higher back up time then you should go for 2nd option
May be this will help you.
