AC Connector: Please distinguish the on-grid and back-up connector, On-grid connector is red
and Back-up connector is Black.
Batte power cable: If the conductor core of the batte cable is too small, which may cause poor
contact between the terminal and the cable, please use the cable specied in the above table, or
contact Wattsonic to purchase terminals of other specications.
