When choosing a home photovoltaic energy storage inverter system, some functions are not clearly introduced in the parameters or manuals of the inverter, but it is very meaningful to the actual application. Xiaogu's article mainly introduces the following functions:

Election output function

In the application scenarios of three -phase households such as Germany and Austria, or in industrial and commercial application scenarios such as shopping malls, parking lots, and stations, the three -phase photovoltaic RESIDENTIAL ENERGY Storage System is usually the best choice. However, to supply power on the single -phase load in the system, different sizes of electrical energy need to be transported on each aspect. We call it "unbalanced output function".

The photovoltaic RESIDENTIAL ENTORAGE SYSTEM commonly used function in the instructions

In the scene of anti -countercurrent, if the uplink power control is phase -by -phase (single -phase level control), then the unbalanced output function will be important because the uplink power of each phase will be limited separately. This requires the inverter to output different power according to the load of each phase.

100 % imbalance function

100 % unbalanced output means that the range of the output power of each phase is 1/3 of the 0W to the inverter nominal power, and the maximum difference between the output power per two phases can also reach 1 / 3.

In order to achieve unbalanced output, a smart meter with a CT function is usually used to monitor the load consumption running each phase in real time, so that the inverter can adjust the output power of each phase accordingly.

Seamless switching of power outages

The output capacity or backup power supply capability is an important feature of photovoltaic Residential Energy Storage System. In particular, the power supply of the public power grid is unstable or the load of important households requires uninterrupted power supply. In this case, the energy storage inverter should have the ability to depart output and automatically switch to the output state from the grid -connected state.
