Battery Cables and Sizing
Select the correct battery cables for the installation from the table. It is important to use the correct
cable to achieve maximum efficiency from the system and reduce fire hazards associated with overheated
cables. Undersized cables can also l o w e r t h e i n v e r t e r ’ s p e a k o u t p u t v o l t a g e a s w e l l a s r e d u c e

WARNING: De -energize all sources of power including batteries ( D C ) , shore power ( A C ) , and AC
generator (if applicable).
CAUTION: Inverter is NOT polarity protected. Verify proper polarity BEFORE connecting the b attery
cables.

Positive Cable
Route a positive cable (RED) from the house battery bank (or dedicated battery compartment) to the
Fuse Block assembly (DC Disconnect). The DC disconnect is usually located next to o r near the batteries.
DO NOT connect the positive cable to the batteries at this time.
