PV inverter with decoupled active and reactive power control

In this condition, if the first stage of the PV inverter keeps working in MPPT mode, there would be an increase in the DC link. The DC-link can rise to a substantial level that the inverter may disconnect from the grid. Post-fault over-current can also disrupt the PV inverter, and it should also be avoided.

Solar, battery and hybrid inverters explained

The primary difference is that multi-mode hybrid inverters also contain an integrated solar inverter (MPPT), while off-grid inverter-chargers do not. The reason is off-grid inverter-chargers are modular and designed to be either AC-coupled with solar inverters or DC-coupled with solar charge controllers.
