Series – Parallel Connection
When pairs of batteries are connected in series and parallel, the result is an increase in both the
voltage and the capacity of the total battery bank. This creates a larger, higher-voltage battery bank
out of several smaller, lower-voltage batteries – a common practice in battery/inverter systems. In
the illustration, each battery in the bank has 100 amp-hours capacity at 6 VDC. The advantage is the
battery bank will have 400 amp-hours capacity at 12 VDC.

Batteries can produce extremely high currents if they are short-circuited. Be
very careful when working around them. Read the important safety instructions
at the start of this manual and the battery supplier’s precautions before
installing the inverter and batteries.
