Note: The charge controllers can be set to a 3-stage charging cycle, but the inverter should be kept in a 2
stage charging cycle. Doing so, as well as setting the charge controller recharge voltage to be greater than
that of the inverter recharge voltage, will prioritize charge controller charging over the inverter charging.
Inverter charging is a grid/generator charge which has a lower priority than solar charge controller charging.

20% state of charge is approximately 51.0V.
95% charge is approximately 53.7V. A 100% charge 54.4V.
NOTE: Voltages are open circuit resting measurement. The settings that would discharge the battery down
to 49V, is too low for Fortress batteries. Fortress batteries should only be intentionally discharged down to
20% SoC or 51.4V and then be recharged by available charging sources.
