protector or disconnection device between battery and the inverter. It may not be necessary to have a
disconnection device in some applications, however, it’s still recommended to have over-current protection
installed. Please refer to typical amperage as required.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It’s very important for system safety and efficient operation to use
appropriate cable for battery connection. To reduce risk of injury, please use the
