* 200 ah batteries shown for illustration.
^ Bank Capacity = (single battery capacity) x (# of
batteries) 400 ah capacity is for two, 200 ah batteries.
Connect the batteries in parallel as
shown above. Connect all of the
positive terminals to one another.
c. Then connect all the negative
terminals to one another.
d. Connect the negative and positive output cables
to opposite ends of the bank. Do not allow
the output cables to touch one another.
e. Test the voltages at the output cables to help
ensure that the battery bank is properly wired.
If the voltage is higher than 13 volts, then part
of the battery bank is likely connected in series
(a negative terminal of one battery attached
to a positive terminal of another) instead of in
parallel. Carefully examine the diagram and
correct the wiring before attaching to the inverter.
6. Turn the inverter’s Switch off.
7. Connect the output cables from the
battery bank to the inverter.
