30s,10s and 2s respectively.
NOTE: Just only the Load over load and the Load short circuit can be cleared by
pressing the button.
Load control setting
(1) Manual Mode
(2) Light ON/OFF (Default)
(3) Light ON +Timer
(4)Output mode
The load will be on for 24 hours. The button is disabled.
(5)Test mode
The same as light ON/OFF mode but no 10 minutes delay. The test mode is only used to
test load switch. It can return to the previous mode after controller restart.
NOTE: In the mode of Light ON/OFF and Light ON + Timer, the Load is turned on
after 10minutes delay.
7. Protection
PV Short Circuit
If the PV array short circuit, the controller will stop charging, clear it to resume normal
operation.
PV Reverse Polarity
Fully protection against PV reverse polarity, correct the wire connection to resume
normal operation.
Battery Reverse Polarity
Fully protection against battery reverse polarity, correct the wire connection to resume
normal operation.
Battery Over Voltage
When the battery voltage reaches to the set point of Over Voltage Disconnect Voltage,
the controller will stop charging the battery to protect the battery from being over
charged to break down.
Battery Over Discharge
When the battery voltage reaches to the set point of Low Voltage Disconnect Voltage,
the controller will stop discharging the battery to protect the battery from being over
discharged.
Battery Overheating
The controller detect the environment temperature through the external temperature
sensor. If the environment temperature exceeds 65 º C, the controller will automatically
start the overheating protection to stop working, and recover below 50 º C.
Load Overload
Load will be switched off when 1.05 times rated current overload happens. Controller will
automatically attempt to reconnect load for 5 times. If overload protection still exist after
controller's 5 times attempts, user have to reduce load appliance, then press the button
or repower the controller or wait for one night-day cycle (night time>3 hours).
Load Short Circuit
Load will be switched off when load short circuit (≥4 times rated current) happens.
Controller will automatically attempt to reconnect load for 5 times. If short circuit
protection still exist after controller's 5 times attempts, user have to clear short
circuit ,then press the button or disconnect and restart the controller or wait for one
night-day cycle (night time>3 hours).
Controller Overheating
If the Internal temperature of the controller exceeds 85 º C, the controller will
automatically start the overheating protection, and recover below 75 º C.
High Voltage Transients
The controller is protected against small high voltage transients. In lightning prone
areas, additional external suppression is recommended.

Troubleshooting
Confirm that PV and battery wire
connections are correct and tight
Measure battery voltage with the
multi-meter. Min.8V can start up the
