According to the rating I should get 20x550 = 11000watts . But the system only produce about 3.4kw .inverter shows My solar screen is displaying Current Overflow and a constant low beeping. Is something wrong or is this a normal function. Any help would be greatly appreciated.
Conducting a bi-annual survey of the installation site is a good idea. If shading is not an issue, most likely it will be the higher than normal operating temperature of the solar panels. It has been scientifically proven that the voltage drop rises with the rise in temperature. The higher the temperature, the lower will be the power output.
The higher the temperature, the lower will be the power output. Adding more modules in series, and therefore increasing the string voltage, will eliminate this problem. Also, make sure that there's sufficient air circulation beneath the panels and that this open space is not blocked in any way.
When check on the multimeter the panel is at between 22 and 19.5v with about 56.5amp. The connection wire from the solar to the controller is 2m, and from the controller to the about 40cm. And from that I can light 2x 6w light bulbs then charge mobiles phone.
