NOTE
NOTE
PV input cables can only be used in scenarios with solar energy.
PV input cables and battery cables are finished cables. You only need to strip the cables and then insert them into the cable terminals.
AC input cables need to be prepared onsite. Multi-core cables must be used; otherwise, waterproof connectors may be exposed to water
leakage.
Before assembling cables with waterproof connectors, ensure that the connections between the cables and terminals are secure and reliable.
