Step 3
Connect a wire from the POSITIVE terminal of the first battery string to the inverters
POSITIVE DC terminal (via a fused device).
Connect the NEGATIVE terminal of the second battery string to the inverters NEGATIVE DC
terminal.
NOTE: Connecting the positive and negative wires to the inverter from different strings ensures a
balanced charge/discharge through the batteries, resulting in longer run times and improved battery
life.
