Using Multiple Batteries
As your power requirements increase, you may need to use more than one
battery to obtain sufficient capacity. Read “Two Batteries Connected In
Parallel” on page B–6 and “Two Separate Battery Banks” on page B–6 to
determine whether two batteries or two battery banks are more
appropriate for your applications.
Two Batteries Connected In Parallel
Two identical batteries can be connected positive (+) to positive (+) and
negative (–) to negative (–) in a parallel system. A parallel system doubles
capacity and maintains the voltage of a single battery.
Two Separate Battery Banks
If you need more than two batteries (or are using different makes or
models of batteries), Xantrex recommends that you install two separate
battery banks and a battery selector switch.
By installing a battery selector switch, you can select between the two
battery banks, use both banks in parallel, or disconnect both banks from
the load. Battery selector switches are available at marine and RV dealers.
CAUTION
Do not connect the following in parallel:
•
batteries made by different manufacturers
•
different types of batteries
•
batteries that have different Ah ratings
Decreased battery life and improper charging will result.
