Deep-Cycle Lead-Acid Batteries
Purpose
Deep-cycle lead-acid batteries are designed for deep
discharge service where they will be repeatedly discharged
and recharged. They are marketed for use in recreational
vehicles, boats, and electric golf carts—so you may see them
referred to as RV batteries, marine batteries, or golf cart
batteries.
Average and Heavier Loads
For most applications of the PROwatt 600 Inverter, Xantrex
recommends that you use one or more deep-cycle batteries
that are separated from the vehicle’s starting battery by a
battery isolator.
A battery isolator is a solid-state electronic circuit that allows
equipment to be operated from an auxiliary battery without
danger of discharging the vehicle’s starting battery. During
vehicle operation, the battery isolator automatically directs
the charge from the alternator to the battery requiring the
charge.
Figure 6 shows a battery isolator.
Battery isolators are available at marine and RV dealers and
most auto parts stores.

Importance of Battery Size
Battery size or capacity is as important as the battery type
you use.
CAUTION
The PROwatt 600 must only be connected to
batteries with a nominal output voltage of 12 volts.
The PROwatt 600 will not operate from a 6 volt
battery and will be damaged if connected to a 24
volt battery.
