- 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...

Calibrating Outback Systems
Calibrating the battery literally means charging the battery 100% full and confirming the
battery resting voltage is above 54V. This can be done onsite or remotely.
Calibration is not a regular task. Good times to calibration are:
• System commissioning
• occasionally when batteries are kept 80-100% full
• deep discharge recovery
• extended periods of overcast / low production days
• anytime when the % state-of-charge says 100% but battery voltage is below
54V
Conforming calibration is easiest to do online but can be done
onsite.
1) Go to OpticsRE.
2) Reduce all system loads and charging to a bare minimum, including charge
controllers.
3) Determine the battery voltage on the inverter terminals.
4) Calibrate the charge controllers to match the inverter terminals.
5) Determine if the FlexNET DC also needs calibration and follow this link for further
