FAQ

Why does too far grid-connected distance leads to voltage rise of on-grid inverters?

If the distance between on grid inverters and grid-connected points is too far, the voltage difference at the AC terminal side of the solar on grid inverters will increase. When the voltage range of grid-tied inverters exceeds the prescribed grid-connected voltage range of the inverters, the inverters will show the overvoltage of the grid. In addition, the long, thin, winding or irregular material of the cable used to connect the inverters to the grid will lead to the increase of voltage difference at the AC end of the inverters, so the selection and rational layout of the cables are particularly important.

In view of this situation, the first thing is to check whether the grid-connected distance is too long, and the best way is to select the near grid-connected scheme. Secondly, to check the cable distribution and quality, and to select reasonable wiring mode and qualified AC cable.

Sleek and reliable for small solar setups.

I added this 350W micro inverter to a small solar array on my shed, and it has been performing great, even during cloudy periods. I like the low-profile design; it’s not bulky and seems to handle heat and weather well with its IP65 rating.
