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.
