Step 1 – Getting Started. Turn each battery on individually while unpacking the batteries and note the voltage of
each battery as well as the serial numbers. The batteries must be within +/- 0.5V of each other before commissioning.
Turn off the batteries and install in parallel. Install the battery-to-battery communication cables and proceed with
system commissioning.
Pro tip: If the battery voltages are significantly different, wire the batteries in parallel without communication cables
and only turn on the lowest voltage battery. Use the inverter or external charger to charge the battery to the voltage
of the 2
nd
lowest battery. Turn the 2
nd
battery on and charge the battery bank to the 3
rd
lowest battery voltage. Repeat
until all batteries are at the same voltage. Keep total charging voltages under 15A per battery during this process.
Pro tip: If the batteries are just slightly outside the +/- 0.5V range, you can avoid using an inverter or an external
charger to balance the batteries by only turning the lowest voltage batteries on (ONLY if within 0.5V relative to each
other) and allowing those batteries to balance. Repeat this process with the highest voltage batteries. This brings the
lowest and highest voltage battery towards to the middle of the group.
Pro tip: It is not usually necessary to apply a firmware update to Fortress batteries during system commissioning, but
our installer firmware update tool can help speed up commissioning times.
Step 2 – Update Schneider Firmware
Please refer to Schneider’s step-by-step guide for the commissioning of a system with 1 XW Pro hybrid inverter, 1
MPPT charge controller, and a Gateway/InsightHome/InsightFacility.
