•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 generated by the battery bank. Typically, an
ANL/Class-T fuse with fuse holder is used.
○
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 two or both (paralleling) battery banks (if

The typically recommended wire length is limited to 5 feet or less for each of the positive and the negative. For longer
wires, a proportionally thicker gauge is required to compensate for additional voltage drop
CAUTION: These guidelines assume you are using the DC supplied cable and fuse sizes
recommended in this manual. The use of a thinner gauge in the DC wires may cause the
inverter to trigger the under-voltage shut down under heavy load conditions. It may also melt the
wire insulation and catch fire, resulting in death or serious injury. The choice of the wire gauge
should also match or exceed the ampacity rating of the DC fuse being used.

AC Load on Inverter
Although the Power Inverter can provide high surge power up to two times the rated output power,
some high surge loads like air conditioners, sump-pumps, heavy duty motors etc. may still trigger the
inverter protection system even though the load falls within the power rating of the inverter. A higher
power Inverter-Charger is required for these appliances.
