There are two major types of PV Off Grid Solar Inverters, transformer-less and transformer isolated ones. Transformer-less inverters can suffer from large ground leakage current and injected dc current because of large panel capacitance and lack of isolation between the PV panel and ac grid, as shown A dc component in the injected ac currents into the grid is less than desirable as it can potentially saturate distribution transformers. There are strict grid requirements for the amount of dc injection in many safety standards and, in some cases, transformer isolation is mandatory. Transformer isolation between the panel and grid would eliminate such a dc injection path arising from the voltage variation of the panel relative to the grid, as shown. Besides dc injection, grid-tied inverters need to meet other grid requirements, such as total harmonic distortion and individual harmonic current levels, power factor, and detection of island operation. The grid voltage and the current injected into the grid need to be monitored accurately. If the controller to perform MPPT and the gate driving function sits on the panel side, these measurements need to be isolated. To operate the PV panel for maximum efficiency, (MPPT) algorithms need to be used. To achieve MPTT, the panel voltage and current also need to be monitored. The panel voltage can get quite high as people try to connect many PV inverters in series to minimize the number of inverters needed. The current measurement from the high side terminal of the PV panels also needs to be isolated.
