temperature exceeds 65 °C and begins working when its temperature is below 55 °C.
Lithium Battery Low
Temperature
When the temperature detected by the optional temperature sensor is lower than the Low Temperature Protection Threshold
(LTPT), the controller will stop charging and discharging automatically. When the detected temperature is higher than the LTPT,
the controller will work automatically (The LTPT is 0 °C by default and can be set within 10 ~ -40 °C).
Load Short Circuit
When the load is short-circuited (The short circuit current is • WLPHV WKH UDWHG controller load current), the controller will
automatically cut off the output. Suppose the load reconnects the output five times (delay of 5s, 10s, 15s, 20s, 25s). In that case,
it needs to be cleared by pressing the Load button, restarting the controller, or switching from Night to Day (nighttime > 3 hours).
Load Overload
When the load is overloading (The overload current is • 1.05 times the rated load current), the controller will automatically cut off
the output. Suppose the load reconnects five times (delay of 5s, 10s, 15s, 20s, 25s). In that case, it needs to be cleared by
pressing the Load button restarting the controller, or switching from Night to Day (nighttime > 3 hours).
Controller Overheating
ƾ
The controller can detect the temperature inside the battery through an optional remote sensor. The controller stops working
when its temperature exceeds 85 °C and begins working when it is below 75 °C.
TVS High Voltage
Transients
The internal circuitry of the controller is designed with Transient Voltage Suppressors (TVS), which can only protect against
high-voltage surge pulses with less energy. Suppose the controller is to be used in an area with frequent lightning strikes. In that
case, it is recommended to install an external surge arrester.
ȝ
When the internal temperature is 81
đ
, the reducing power charging mode is turned on. It reduces the charging power by 5%,10%,20%, and 40% with every
increase of 1
đ
. If the internal temperature exceeds 85
đ
, the controller will stop charging. But while the temperature declines below 75 ºC, the controller resumes.
6.2 Troubleshooting
x
Controller Faults
Faults Possible reasons Troubleshooting
Charging LED indicator off during daytime when sunshine
falls on PV modules properly
PV array disconnection
Confirm that PV and battery wire connections are
correct and tight
The wire connection is correct, and the controller is not
working.
Battery voltage is lower than 9V
Please check the battery voltage. At least 9V to activate
the controller.
