Troubleshooting
LED indicator is red.
• Check app interfaces for error details.
Wiring is complete but charger won't power on.
• Ensure correct polarity connection between the charger and the vehicle starter battery or RV
house battery.
• Verify that all terminals of the cables are connected firmly.
• Verify that the nominal voltage of the vehicle starter battery or RV house battery is 12V or
24V.
• Check whether the negative terminal of the Input Cable is connected to the negative terminal
of the starter battery. If yes, connect the negative terminal of the Input Cable to the chassis
and try to power on the charger again.
In Charge Mode, the charger is working but the power station or extra battery won't charge.
• Upgrade the firmware of your portable power station or extra battery to the latest version in
the app.
• Check whether you've set a charge limit for your power station in the app.
Output power doesn't reach the maximum.
• Check whether you've set the output power of the charger in the app.
• The alternator's output may be low. Boost its output (e.g. by pressing the accelerator) and
then try again.
In Charge Mode, the output power fluctuates dramatically.
• The reason could be that a battery sensor module is connected to the negative terminal of the
starter battery. Connect the negative terminal of the Input Cable to the chassis and try again.
Power station or extra battery turns off after putting the charger into standby state.
• Upgrade the firmware of your portable power station or extra battery to the latest version in
the app.
