ESD cannot be responsible for any mistakes this calculator could make.
How to use the Calculator:
- Enter the hours of No Charge, the longest day. This would be the amount of time the standby battery would have to carry the load.
- Enter the Watts required to power your load. Watts equals Volts times Amps.
- The answers should be self explanatory. The required power supply would be the amps available to recharge the battery and power the load during the re charge time.
