- Unpack Batteries and 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
