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.

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.
Importance of Battery Size
Battery size or capacity is as important as the battery type you use.
