EcoRenovator - View Single Post - Moving solar from Grid to off grid (Sunny Boy GTI)

Hi All...

I have a 2KW system on my roof... and plan to move it to a cabin currently being built that is 100% off grid. My system uses a Sunny Boy US3000 GTI...

Of course, the GTI has sensing circuits that serve to interlock the inverter which will prevent it from functioning off grid.

Certainly, the Sunnyboy GTI is approx. the same as the off-grid inverters of the same family... just with the additional interlock circuits.

I would like to modify my GTI to act like an off-grid inverter when I move it to the cabin... I suppose a Sunny Boy service manual would be helpful in such a conversion project.

Has anyone here attempted such a conversion, or had any luck obtaining a service manual for the Sunny Boys?
