- Unpack Batteries + Check Voltage
- 1. Unpack the batteries and turn each battery on by itself.
- 2. Note the voltage of each battery and serial number. The serial numbers are useful during warranty submittal.
- 3. The batteries must be within +/-0.5V of each other before commissioning. Groups of 4 batteries or more may require a narrower voltage range to commission properly.
- 4. Turn off the batteries and install them in parallel. Notes
- If the battery voltages are significantly different, one technique is to finish battery installation and only turn on the lowest voltage battery using the pushbutton. Charge the battery, and when the charging voltage is ~0.2V above the resting voltage...
- If the batteries are slightly more than +/-0.5V from each other, turning on the highest voltage batteries only will reduce their voltages, and turning on the lowest voltage batteries only will lower the highest voltage. Likewise, turning on the lowest...
- Use of the Fortress firmware update tool can help speed up commissioning times. Fortress installers should request a firmware update tool by filling out a support ticket at https://support.fortresspower.com

Firmware updates are rarely needed. Most firmware updates solve a minor issue - major
firmware updates typically are adding compatibility with new-to-market hardware or to
accommodate developments in battery-inverter communication.
Most of our installers use the firmware update tool to confirm proper system
commissioning or unlock batteries from their protective modes during a deep discharge.
To update the battery firmware, please visit https://www.fortresspower.com/firmware.
Solar contractors should visit https://www.fortresspower.com/support and request a
firmware update tool.
If you cannot determine the instructions, we are happy to assist you with a remotely -
there are things we can do before you visit site to make your site visit much easier, and
we can also assist you onsite (preferably scheduled in advance).
Firmware update tools are available for sale
at https://www.fortresspower.com/products/firmware-update-tool/
However, we recommend end users wait for the Fortress Guardian Hub instead of
buying the firmware update tool.
Voltage to % Chart
The voltage curve of lithium is very flat from the bottom 20% of the battery to the top
80% of the battery, at which point is becomes rather steep at both ends. It is very easy
to tell when a battery is moving towards the bottom or top of its range - the middle bit
is hard to guess because it will fluctuate with load. Here is a very loose approximation of
Fortress battery voltage and state-of-charge:
