When the charging current or power of the PV array exceeds the
controller's rated current or power, it will be charge at the rated
current or power.
WARNING: When the PV's charging current is greater than the
rated current, the PV's open circuit voltage cannot be greater than
the "maximum PV open-circuit voltage", otherwise the controller
may be damaged.
When not in PV charging state, the controller will not be damaged
in case of a short-circuiting in the PV array.
WARNING: DO NOT short-circuit the PV array during charging.
Otherwise, the controller may be damaged.
When the polarity of the PV array is reversed, the controller should
not be damaged and can continue to operate normally after the
polarity is corrected.
CAUTION: If the PV array is reverse polarity connected to the
controller, and the PV array's actual operating power is greater
than 1.5 times the rated charging power of the controller, the
controller will be damaged.
Prevents the battery from discharging to the PV module at night.
Fully protected against battery reverse polarity; no damage
will occur to the battery. Correct the wiring to resume normal
operation.
WARNING: Limited to the characteristic of lithium battery, when
the PV connection is correct and 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 prevent
battery damage caused by over-discharging. NOTE: Any
controller-connected loads will be disconnected. Loads directly
connected to the battery will not be affected and may
continue to discharge the battery.
