4. Program the Discharge Tab:
Notes:
a) Shutdown turns the inverter off and waits for the sun to recharge the battery, whenever that
may be in the future. You can increase the shutdown level to increase the "reserve capacity"
of the system, but that will prevent that battery range to be used. The correct shutdown level is
specific to the project site.
b) Low battery is an alarm also specific to the project site, integrated with the Sol-Ark monitoring
app. We suggest a 20% state of charge as a good low battery alarm level, but it can be higher.
c) The battery empty voltage should not be lower than 48V. If increasing the reserve capacity in
the above note a, then increase the battery empty voltage to 49V or 50V. More on voltage levels
later.
