GivEnergy Hybrid inverter, and other generation

Does anyone know if a GivEnergy hybrid inverter would be able to charge its batteries using generation other than its own DC-connected inputs?

My theoretical setup would be the existing 5kW hybrid inverter (with a pair of 8.2kWh batteries), and another separate simple string inverter - possibly with some combination of more solar and a small turbine. This would be located down the garden, and I don’t see any likelihood of attaching batteries to it.

In such a setup, I imagine the GivEnergy hybrid inverter’s CT clamp would see the unused additional generation flowing out to the grid - would it start charging from this unexpected power source? Thinking about it, that must be how the AC-coupled battery inverter works, so can the hybrid do the same?

Having received approval under G99 for our 5kW export, what are the chances of a subsequent G99 (to a combined 10kW) being approved on a 100A single phase supply? (I know there are many factors, but in an ideal world, would that ever be possible.)

Thanks very much in advance!

adamdoran when I asked last year, the answer was no, the hybrid will not charge the battery automatically with exported power from another AC-connected system. It would be very nice if it did!

stevelewis that's obviously disappointing, but useful to know before I go making too many plans. Thanks for your help.
