Connecting Batteries
In most cases, you will be using a bank of two or more batter-
ies with your Freedom Inverter/Charger. Depending on your
batteries’ voltage, you may connect batteries:
• In series to increase the battery bank’s voltage
• In parallel to increase the battery bank’s amp-hour capac-
ity
You should increase the voltage of a battery bank connected in
series until it matches your system’s voltage. Your battery
bank’s final DC voltage depends on your system. It should be
12, 24 or 32 volts.
Then you should connect the batteries in parallel to increase
the available amp-hours.
Installation Notes
• Always use properly sized wire and terminals for the
interconnecting battery cables. The cables must be, at a
minimum, the same AWG as those connected to the in-
verter/charger. For size information, refer to National
Electrical Code (NEC) requirements or contact your local
electrician. See “Selecting battery cables” on page 24 for
more information.
• Only similar batteries should be connected together in one
bank. Do not connect wet cell, gel cell or AGM batteries
together.
• Do not connect batteries with different case sizes or amp-
hour ratings in the same battery bank.
• Do not connect old and new batteries together.
• Use hex nuts and lock washers on the battery terminals. If
your battery comes with wing nuts, replace them with hex
nuts.
