When the charging current or power of the PV array exceeds
the controller's rated current or power, it will change at the
rated current or power.
When not in the PV charging state, the controller will not be
damaged in 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 can continue to operate normally
after the polarity is corrected.
NOTE: If the PV array is reversed and the actual power is
1.5 times the rated controller's power, 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: Limited to the lithium battery's characteristic,
when the PV connection is correct, either the BATT1 or
BATT2 battery connection reversed, the controller will
be damaged.
When the battery voltage reaches the over voltage
disconnect voltage, it will automatically stop battery charging
to prevent battery damage caused by over-charging.
When the battery voltage reaches the low voltage
disconnect voltage, it will automatically stop battery
discharging to
over-discharging. (Any controller connected to the loads will
be disconnected. Loads directly connected to the battery will
not be affected and may continue to discharge the battery.)
The controller can detect the battery temperature through an
external temperature sensor. The controller stops working
when its temperature exceeds 65 ° C and restarts to work
