Xantrex Technology TS400 manual Using Multiple Batteries, Two Batteries Connected In Parallel

Battery Types and Sizes

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–6and “Two Separate Battery Banks” on page B–6to 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.

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.

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.
