When the charging current/power of the PV array exceeds
the rated charging current/power, the PV array will charge
the battery as per the rated charging current/power.
When not in the PV charging state, the controller will not be
damaged in the case of a short-circuiting in the PV array.
When the polarity of the PV array is reversed, the controller
may not be damaged and resume normal operation after
the mis-wiring is corrected.
NOTE: If the PV array is reversed and the actual power is 1.5
times the rated power of the controller, the controller will be
damaged.
Prevent the battery from discharging to the PV module at
night.
When the polarity of the battery is reversed, the controller
may not be damaged and resume normal operation after
the mis-wiring is corrected.
NOTE:
The
controller,
characteristic, will be damaged when the PV array connection
is right and the battery connection is reversed.
When the battery voltage reaches the over voltage
disconnect voltage, the PV array will automatically stop
charging the battery to prevent battery damage due to
overcharging.
When the battery voltage reaches the low voltage
disconnect voltage, battery discharging will automatically
stop to prevent the battery from damaging due to over-
discharging.
