Reverse Power to Generator in AC Coupled Off grid System
The Victron limits the battery voltage, and the maximum current into the battery. You can therefore get a situation where the solar generation (minus loads) is putting more power into the Victron than it can use. If the generator is off, then the Victron will frequency-shift and this will reduce the solar power output.

6 Frequently Asked Questions about “Solar power generation reverse power”
How does reverse power flow affect Protection coordination scheme?
The reverse power flow occurs when the production of DG exceeds local load demand or when local demand reduces so that power flows in the opposite direction and causes abnormal performance of the protection system. In this section, the effect of reverse power flow on the protection coordination scheme is analysed.
What is reverse power relay (RPR) for solar?
Reverse power relay (RPR) for solar is used to eliminate any power reverse back to gird from an on-grid (grid-tie) PV power plant to the grid or to the generator by tripping either on-grid solar inverter or breaker or any contactor depending upon the type of power distribution and a control circuit.
What happens if you reverse power flow in a low-voltage network?
Reverse power flow in a low-voltage (LV) network can cause instability, such as in the line sections and distribution transformers [19, 20]. The overloading of the distribution transformer is one consequence of a low-load, high-PV penetration network; higher voltages are also seen at low-voltage (LV) and medium-voltage (MV) levels. [21, 22].
