Grid Tied Solar Inverter

The classic grid-connected PV inverter converts the direct current supplied by the PV modules into grid-compliant alternating current. The energy only flows in one direction, towards the AC house or public grid. He monitors and optimizes the system performance and safety. The performance and many other data are stored and usually also made available in an online monitoring platform.

Together with a digital energy meter from the same manufacturer, e.g. set zero feed into the public grid.

Should the public power grid fail, the grid-connected PV inverter also switches off immediately.

Usually, PV inverters are designed / selected to be approx. 5% smaller than the PV module output. The module voltage of the connected module string should be within the MPPT working range of the inverter.

The mostly used transformerless devices perform a litte bit better if the Voltage is in a higher range. 

Such a grid-connected solar power system can be easily expanded by adding a battery inverter with storage (later or immediately). This is easily possible at any time.
