2. Low Voltage Indicator, red, bright indicate the voltage of the battery is low. Load
could not normal working. This is normal phenomenon. When the battery voltage
recover to 12.6V or (25.2v), the Load will be automatically working, at this time the
indicator is off.
3. Charge Indicator, green, bright indicate the battery need to charge, flickering means
float charging, off means charge has stop.
RESET Button:
The rated output current of this MPPT solar charge controller is 20A
（
30A
）
, if there is short circuit or overload happened, the MPPT controller will close
output. ( Load indicator off, Low voltage indicator off.)
If you need the MPPT controller recover work, please check the reasons and clear out the
fault firstly. Then put a small stick such as toothpick, ball-pen tip inside the RESET hole,
and press RESET button will be OK.
Attention:
1. Please check the rated voltage of the solar panel, battery, load are all the same
with 12V or 24V or 48V.
2. Please pay attention to connection, do not connect the “+” “-” poles of solar
panels and load wrong.( Wrong connection will be burn your MPPT controller)
3. Battery must be connected earlier than solar panels and load. When take off the
system, Solar Panels must be take down first, then cut off battery.
4. The rated current of solar panel and load must be less than MPPT controller’s
rated current.
