Notes

1Input current based on rated load and batteries fully charged.

2Input current based on full battery recharge, nominal voltage and rated load.

3Current limitation through electronic current limiting is based on full battery recharge and low input voltage.

4Synchronization adjustable: ± 10Hz, ± 3Hz or ± 0.1Hz.

Recommended current protection

Note: AC input/output over-current protection and AC input/output disconnect must be provided by the customer
