Battery Connection
CAUTION
: For safe operation and regulation compliance, it's required to install a separate DC
over-current protector or isolator between battery and inverter. It may not be required to have a
battery isolator in some applications, however, it's still required to have an over-current protection
installed. Please refer to table below for typical amperage to determine required fuse or breaker
and cable size.
WARNING!
All wiring must be performed by a qualified person.
WARNING!
It's very important for system safety and efficient operation to use
appropriate cable for battery connection. In a parallel system (two or three units)
make the battery cables the same length.

Please follow below steps to implement battery connection:
1. Fit recommended cable lugs to battery cables.
2. Connect batteries to make a 48V battery bank. Suggested battery capacity is at least 200Ah
for the 4KVA/5KVA inverter model.
NOTE
: Only use Deep Cycle Flooded/GEL/AGM lead acid battery or approved Lithium batteries.
