Electrical Connection Overview
• Make sure to match the polarity of the cables properly when installing. Otherwise,
it may cause electric shock or the product may permanently be damaged. The
damage from this is not covered by the warranty.
• Before batteries are connected, all other connections should be done and the
battery interrupter must be off.
Before connecting electrical cables, make sure the AC circuit breaker, PV switch, and DC switch are
OFF.
