• Based on the size of the Battery Bank, determine the overall short circuit current rating of
the battery bank from the battery manufacturer. The fuse or circuit breaker has to be able
to withstand the short circuit current that can be supplied by the battery bank.
• For battery banks with total capacity under 500Ah the most aordable ANL fuse type can
be used. Otherwise use Class-T type.
C DC Disconnect Switch
• A DC Disconnect Switch connected along the DC positive line is recommended. The
rating of the switch is with the same or higher rating of the selected fuse or circuit breaker.
Use ignition protected switches when required by local codes.
• This switch is used to disconnect the positive of the battery bank to the unit’s positive
terminal during maintenance/repair service, when not in use, or when troubleshooting.
It could also be an A/B/A+B/OFF type switch to select either one of the two or both
(paralleling) battery banks (if available).
D DC Input Cable
• All DC Input Wires should be insulated multi-strand low resistance wires.
• The DC wires must be copper and with minimum 105orating.
