What to do if iTechworld 40Amp MPPT shows overload detected?
- MMrs. Ashley SnyderAug 4, 2025
If the iTechworld Controller detects an overload, reduce the load on the load output of the solar charge controller.
What to do if iTechworld 40Amp MPPT shows overload detected?
If the iTechworld Controller detects an overload, reduce the load on the load output of the solar charge controller.
How to fix iTechworld 40Amp MPPT Controller over temperature?
To resolve an over-temperature issue with your iTechworld solar charge controller, ensure it has adequate ventilation and that none of the heat sink fins are blocked. Allow the regulator to cool down; it will restart charging automatically once cooled.
Why is my iTechworld Controller not charging the battery with enough sunlight?
If your iTechworld Controller isn't charging the battery despite sufficient sunlight, it could be due to a disconnected solar input or the solar input voltage being lower than the battery voltage. Check that all solar input connections and fuses/breakers are correctly connected. The voltage of the solar panel should be more than the battery voltage.
What to do if the input voltage of iTechworld 40Amp MPPT Controller solar panels is too high?
If the input voltage of the solar panels connected to your iTechworld Controller is too high, check the voltage of the solar input and reduce the number of panels connected in series.
What to do if iTechworld 40Amp MPPT detects over voltage?
If your iTechworld Controller detects an over voltage, check that the selected battery profile is correct for the battery connected.
What to do if nothing is displaying on the LCD of iTechworld 40Amp MPPT Controller?
If nothing is displaying on the LCD of your iTechworld Controller, check the battery voltage, connections, and fuses. The controller will only turn on if the battery is above 8 Volts, because the battery voltage is less than 8 Volts or there are incorrect connections.
