6 FAQs about [Inverter grid-connected voltage limit]

Can maximum inverter power limit grid feed-in?

The values of „maximum inverter power“ have always positive sign. Therefore they only limit the charging values for grid setpoint. They cannot limit the negative values for grid feed in. Using Grid feed-in → Limit system feed-in instead, also cannot solve this problem.

What happens if a PV inverter is connected to a grid?

Grid Connection Some properties of a PV inverter grid connection can cause the grid voltage at the inverter to increase and exceed the permissible operating range if the feed power is high. If this occurs, SMA grid guard, an independent disconnection device integrated into the inverter, will safely disconnect the inverter from the grid.

Does maximum inverter power go back if grid setpoint is high?

If „maximum inverter power“ goes back to a higher value, the grid feed in also goes back if grid setpoint is that high. Nevertheless, I expect same behaviour for the “Limit system feed in”. This would allow high inverter power, high self consumption but only low grid feed in.

What happens if an inverter exceeds the voltage limit?

If the inverter records that the 10-minute average exceeds this voltage limit, or if the 260 V limit is temporarily exceeded, it will switch off immediately. The inverter will display a grid error message if this occurs.

Do smart inverters support grid voltage regulation?

of smart inverters to contribute to voltage regulation. The IEEE standard is not prescriptive as to how smart inverters shall support grid voltage management, instead it requires a set of capabilities that smar

What should be included in a grid limit for MPPT inverters?

o The nominal power of each MPPT, taking temperature and Power factor into account o The possible power sharing predefined between MPPT inputs of inverters, o The different charges of each MPPT input (some with N and some with N+1 strings), o The possible self-consumption or battery charging for this hour should be added to the grid limit,
