Check if battery voltage too high, and disconnect solar modules.
When the battery voltage is restored to or above LVR point (low
voltage reconnect voltage), the AC load will recover
The inverter/charger will automatically turn the system off. But while
the battery temperature declines to be below overheating recover
temperature value, the inverter/charger will working.
