Preparing the Battery Bank
Prepare the battery bank according to type of battery selected and
configure the battery bank to optimize voltage output according to system
requirements. See your battery manufacturer’s installation guide for
recommendations.
See
Appendix C, “Battery Information” for additional information on
determining battery bank type and configuration.
Run the positive and negative battery cables as close to each other as
possible by taping them together after all the connections are made. This
reduces the effects of inductance, improves surge capacity and reduces
RFI and EMI emissions.
Install a DC disconnect between the battery bank and the inverter.
Following the manufacturer’s installation instructions.
WARNING: Shock Hazard
Ensure that all AC and DC breakers are switched OFF before
connecting or disconnecting the battery cables and that all
sources of power (both AC and DC) are disconnected from the
inverter’s inputs.
