Hi Guys, really hoping for a unique solution here from the community. We have an isolated farmhouse that currently has a 10Kw wind turbine with single phase 230vac output. ( the original system used an inverter charger connected to wet batteries to deliver 230vac to the house load.
The client has opted for installing a PV solar array delivering about 6.2Kw peak power to a Fronius inverter which will use a Victron Quattro to source the 230vac 50Hz reference, given the house is off grid.
The Fronius has active phase control via the Victron so once the associated new lithium storage is full, the Fronius will throttle off by screwing the 50Hz.
Into this mix we want to add the output of the wind turbine..i.e. the 230vac i.e we are trying to create a micro grid for the house.
The issue we have is that the plan to use a turbine inverter with a simple 230vac output which can be managed by the Victron as the second source of AC power has been thwarted because the wind turbine inverter requires a rock steady 50Hz grid frequency and it will not tolerate even small shifts in the frequency.
Is anyone got some bright ideas how we can still have the Fronius/Victron solution and be able to integrate the other source of 230vac?
