Sol-Ark Integration Guide

Calibration Charge SoC
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
Performing a calibration charge onsite:
1) Go to the battery setup menu.
2) Check "Use Batt V charged" (Use Batt % Charge will unselect).
3) Uncheck "BMS Lithium Batt 04"
4) Switch back to "Use Batt % Charged" and "BMS Lithium Batt 04" after battery climbs above 55V. The Sol-Ark should
read 100% at above >54V after switching back over.
