1.What to look for when servicing an inverter?
(1) Before servicing, first disconnect the electrical connection between the inverter and the grid, and then disconnect the DC side electrical (connection. It is necessary to wait for at least 5 minutes or more to allow the inverter’s internal high-capacity capacitors and other components to be fully discharged before carrying out the maintenance work.
(2) During the maintenance operation, first, visually check the equipment initially for damage or other hazardous conditions, and pay attention to anti-static during the specific operation, it is best to wear an anti-static hand ring. To pay attention to the warning label on the equipment, pay attention to the inverter surface that is cooled down. At the same time to avoid unnecessary contact between the body and the circuit board.
(3) After the repair is completed, make sure that any faults affecting the safety performance of the inverter have been resolved before turning the inverter on again.

2.What is the reason for the inverter screen not displaying? How to solve it?
Cause of occurrence：
(1) The output voltage of the module or string is lower than the minimum working voltage of the inverter.
(2) The input polarity of the string is reversed. The DC input switch is not closed.
(3) The DC input switch is not closed.
(4) One of the connectors in the string is not connected properly.
(5) A component is short-circuited, causing the other strings to fail to work properly.
Solution:
Measure the DC input voltage of the inverter with the DC voltage of the multimeter, when the voltage is normal, the total voltage is the sum of component voltage in each string. If there is no voltage, test whether the DC circuit breaker, terminal block, cable connector, component junction box, etc. are normal in turn. If there are multiple strings, disconnect them separately for individual access testing. If there is no failure of external components or lines, it means that the internal hardware circuit of the inverter is faulty, and you can contact Renac for maintenance.

3.The inverter displays a grid error and shows the fault message as voltage error "Grid Volt Fault" or frequency error "Grid Freq Fault" "Grid Fault"?
Cause of occurrence:
The voltage and frequency of the AC power grid are out of the normal range.
Solution:
Measure the voltage and frequency of the AC power grid with the relevant gear of the multimeter, if it is really abnormal, wait for the power grid to return to normal. If the grid voltage and frequency are normal, it means that the inverter detection circuit is faulty. When checking, first disconnect the DC input and AC output of the inverter, and let the inverter power off for more than 30min to see if the circuit can recover by itself, if it can recover by itself, you can continue to use it, if it can’t be recovered, you can contact Renac for overhaul or replacement. Other circuits of the inverter, such as the inverter main board circuit, detection circuit, communication circuit, inverter circuit, and other soft faults, can be used to try the above method to see if they can recover by themselves, and then overhaul or replace them if they can not recover by themselves.
