The power grid voltage and frequency are too low or too high
Possible causes:
In some areas, the agricultural network has not been renovated, and the voltage of the grid is not within the safety regulations.
Solutions:
Measure the grid voltage with a multimeter, if it exceeds, wait for the grid to return to normal. If the power grid is normal, the inverter detection circuit board is faulty, you need to disconnect all the DC and AC terminals of the machine, let the inverter discharge for about 5 minutes, and then close the power supply; if it can be restored to continue to use it, if it can't be restored, contact the after-sales technical engineers.

The output power of the inverter is small
Possible causes:
There are many factors that affect the power output of a PV plant, including the amount of solar radiation, the tilt angle of the panels, dust and shadow shading, and the temperature characteristics of the PV modules.
Solutions for systems that are underpowered due to improper system configuration and installation:
(1) Before installing, check to see if the pv power is enough.
(2) Adjust the mounting angle and orientation of the pv modules.
(3) Check pv modules for shadows or occlusions.
(4) Check that the pv modules voltage is within the voltage range when connected in series; too low a voltage will cause the system to be less efficient.
(5) Check whether the installation location is ventilated, whether the heat of the inverter can be dispersed out in time, or whether the inverter is in direct sunlight and causes its temperature to be too high.
(6) Check the inverter string power, whether there is poor cable contact, cable is too long, wire diameter is too thin, voltage loss, and finally cause power loss.

What is a household distributed PV system?
A household distributed PV system is a distributed PV system that utilizes buildings within a natural person's homestead, such as an owned residence, as well as appurtenances. Household distributed PV systems are usually characterized by small installation capacity, low voltage level grid connection, and simplified filing and grid connection process.
