    (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.

  • Q10: What is the reason for the inverter screen not displaying? How to solve ?

    General reasons include:① The output voltage of the module or string is lower than the minimum working voltage of the inverter. ② Input polarity of the string is reversed. The DC input switch is not closed. ③ 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 DC voltage of 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 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.

  • Q11: The inverter cannot be connected to the grid and displays the fault message "No Uility"?

    General reasons include:① The inverter output AC circuit breaker is not closed. ② The inverter AC output terminals are not connected properly. ③ When wiring, the upper row of the inverter output terminal is loose.

    Solution: Measure the AC output voltage of the inverter with a multimeter AC voltage gear, under normal circumstances, the output terminals should have AC 220V or AC 380V voltage; if not, in turn, test the wiring terminals to see if they are loose, whether the AC circuit breaker is closed, leakage protection switch is disconnected etc.

  • Q12 : 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"?

    General reason: 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, 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 NATTON for overhaul or replacement. Other circuits of the inverter, such as 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.

  • Q13 : Excessive output voltage on the AC side, causing the inverter to shut down or derate with protection?

    General reason: mainly because of the grid impedance is too large, when the PV user side of the power consumption is too small, the transmission out of the impedance is too high, resulting in the inverter AC side of the output voltage is too high!

    Solution: ① Increase the wire diameter of the output cable, the thicker the cable, the lower the impedance. The thicker the cable, the lower the impedance. ② Inverter as close as possible to the grid-connected point, the shorter the cable, the lower the impedance. For example, take 5kw grid-connected inverter as an example, the length of AC output cable within 50m, you can choose the cross-sectional area of 2.5mm2 cable: the length of 50 – 100m, you need to choose the cross-sectional area of 4mm2 cable: length greater than 100m, you need to choose the cross-sectional area of 6mm2 cable.

  • Q14 : DC side input voltage overvoltage alarm, error message "PV Overvoltage" displayed?

    Common reason: Too many modules are connected in series, causing the input voltage on the DC side to exceed the maximum working voltage of the inverter.

    Solution: According to the temperature characteristics of PV modules, the lower the ambient temperature, the higher the output voltage. The input voltage range of three-phase string energy storage inverter is 160~950V, and it is recommended to design the string voltage range of 600~650V. In this voltage range, the inverter efficiency is higher, and the inverter can still maintain the start-up power generation state when the irradiance is low in the morning and evening, and it will not cause the DC voltage to exceed the upper limit of the inverter voltage, which will lead to the alarm and shutdown.

  • Q15: The insulation performance of the PV system is degraded, the insulation resistance to ground is less than 2MQ, and the fault messages "Isolation error" and "Isolation Fault" are displayed?

    Common reasons: Generally the PV modules, junction boxes, DC cables, inverters, AC cables, terminals and other parts of the line to ground short-circuit or insulation layer damage, loose string connectors into the water and so on.

    Solution: Solution: Disconnect the grid, inverter, in turn, check the insulation resistance of each part of the cable to ground, find out the problem, replace the corresponding cable or connector!

  • Q16: Excessive output voltage on the AC side, causing the inverter to shut down or derate with protection?

    Common reasons: There are many factors affecting the output power of PV power plants, including the amount of solar radiation, the tilt angle of the solar cell module, dust and shadow obstruction, and the temperature characteristics of the module.

    System power is low due to improper system configuration and installation. Common solutions are:

    (1) Test whether the power of each module is sufficient before installation.

    (2) The installation place is not well ventilated, and the heat of the inverter is not spread out in time, or it is exposed to the sunlight directly, which causes the inverter temperature to be too high.

    (3) Adjust the installation angle and orientation of the module.

    (4) Check the module for shadows and dust.

    (5) Before installing multiple strings, check the open-circuit voltage of each string with a difference of no more than 5V. If the voltage is found to be incorrect, check the wiring and connectors.

    (6) When installing, it can be accessed in batches. When accessing each group, record the power of each group, and the difference of power between strings should not be more than 2%.

    (7) The inverter has dual MPPT access, each way input power is only 50% of the total power. In principle, each way should be designed and installed with equal power, if only connected to one way MPPT terminal, the output power will be halved.

    (8) Poor contact of the cable connector, the cable is too long, the wire diameter is too thin, there is voltage loss, and finally cause power loss.

    (9) Detect whether the voltage is within the voltage range after the components are connected in series, and the efficiency of the system will be reduced if the voltage is too low.

    (10) The capacity of the grid-connected AC switch of the PV power plant is too small to meet the inverter output requirements.
