4.4.3 Connect power cables
•
Connect battery power cables in series, which means connect the anode of the battery to the
cathode of the next battery. Connect power lines of the control box and batteries in parallel,
which means connect the negative line of the bat-tery on the upside of the control box to its
cathode while the positive line on the lower side to its anode.
•
Customers have to prepare cables used to connect the main control box and inverter. 6AWG
copper core is recommended.
•
Confi rm that the switch of the control box is off .
•
Ensure that the seal ring of the waterproof joint is properly
placed in the plastic ring.
•
Do not short-circuit the positive and negative terminals
of the battery module when installing because there is no
disconnecting switch in a single battery module.
•
Power cable connection between control boxes and
batteries should follow the principle “positive to positive,
negative to negative”.
•
Connect power cables of all battery modules in
sequence,connect the bottom(negative) to the top battery
module(positive).
•
Power cables connecting the inverter and the battery are
prepared by customers. It’s recommended to use copper
core cables with 6AWG cross-sectional area and copper OT
terminals.
1.Route the cable through the nylon tube, seal ring and waterproof joint, then crimp on OT ter-
minals.
