Cause of occurrence:
The cause of this fault is a communication problem between the main and secondary CPUs of the inverter control board.
Solution：
(1) Restart the inverter (you need to disconnect the PV, AC grid, and batteries and then turn it on again).
(2) If the problem persists after restarting the inverter, check if the software version of the inverter control board is correct. If not, try to burn in the software again.
(3) If the problem persists after burning the software, replace the control board.
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.
Cause of occurrence:
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.
Solutions :
(1) Test whether the power of each PV 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 sunlight directly, which causes the inverter temperature to be too high.
(3) Adjust the installation angle and orientation of the PV 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 in 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.
