What to do if HANCHU ESS HESS shows bypass overload protection or inverting overload protection?
If your HANCHU ESS Inverter indicates bypass overload or inverting overload protection, try the following: 1) Reduce the power consumption of connected devices. 2) Restart the all-in-one machine. This should restore the load output.
What to do if HANCHU ESS HESS shows inverting short-circuit protection?
If the HANCHU ESS Inverter displays an inverting short-circuit protection message: 1) Carefully inspect the load connection to identify and fix any short-circuit issues. 2) After addressing the short circuit, power the system on again to restore the load output.
What to do if HANCHU ESS Inverter displays no connection alarm of battery?
If your HANCHU ESS Inverter is showing a 'no connection alarm of battery', verify that the battery is properly connected and that the breaker at the battery side is closed.
What to do if HANCHU ESS Inverter shows PV overvoltage?
If your HANCHU ESS Inverter indicates PV overvoltage, use a multimeter to check if the PV input voltage exceeds the maximum allowable input voltage.
Why HANCHU ESS HESS Inverter has no display on screen?
If there is no display on the screen of your HANCHU ESS Inverter, check if the battery air switch or PV air switch is closed and ensure the switch is in the "on" state. You may also need to press any key on the screen to wake it from sleep mode.
What to do if HANCHU ESS HESS Inverter's charge battery overvoltage protection is on?
If the HANCHU ESS Inverter shows charge battery overvoltage protection, measure the battery voltage to see if it exceeds 60V. If it does, disconnect the photovoltaic array air switch and the AC air switch.
What to do if HANCHU ESS HESS Inverter indicates a fan fault?
If the HANCHU ESS Inverter reports a fan fault, check whether the fan is not working or if something is blocking it.
