5) Connect the PV modules
Risk of electric shock! When wiring the PV modules, please disconnect the circuit
breaker and ensure that the leads of "+" and "-" poles are connected correctly.
If the inverter/charger is used in an area with frequent lightning strikes, installing an
external surge arrester is recommended.
6) Connect the utility input
Risk of electric shock! When wiring the utility input, please disconnect the circuit
breaker and ensure that the poles' leads are connected correctly.
When the utility is connected, the PV and battery terminals are prohibited from
grounding, while the UPower-Hi shell must be reliably grounded. It can effectively
shield the external electromagnetic interference and prevent the shell from electric
shock to the human body.
