[QUOTE="bignose2, post: 543382, member: 26733"] Hi, I had started out with the thought of the Solis RAI, AC Coupled Battery install which I think is the same as the Growatt spa-3000 & then leaned towards the hybrid option, although taking out a perfectly good non-hybrid inverter I think the install would be more complicated & additional 240v wiring & notification. I know some keep saying that it is changing the loading to the grid, solar & battery combined so would need to notify anyway even with the Hybrid, I am not too sure why. I am no expert, hence asking questions here but the one thing I was always lead to believe as long as correctly spec'd inverter don't need to worry about overloading the grid or the extra DNO G99 notification for the over 3.68kw As long as the Hybrid inverter is limited to 3.6kw I assume works the same way my current one does, i.e. with built in limiter. My PV is 4.4kw but that is fine & actually recommended for best solar capture because it can never send more than the 3.68kw. If this was the case I would think every single hybrid install with batteries would need the g99 application. Now I fully understand if you add an AC battery & extra inverter there must be some mechanism to prevent both discharging as this is a separate load into the CU. [/QUOTE]
