Using Multiple Batteries
C–7
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.
Figure C-2 shows two separate battery banks and a battery selector
switch. This configuration is recommended for heavy-duty applications.
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.
