Solar PV - going bigger

EcoScruples

It's all to do with your inverter, if it outputs 3.68kw then that's the max you can use from your system to your home.
If you have batteries installed with a Hybrid inverter then depending on it's rating it can feed 3.68 to your home and charge a battery with excess at the same time (DC coupled).
There's loads of good YouTube vids explaining DC coupled, A.C. coupled and Hybrid batteries, well worth a search.

So after a lot of delays it was all installed yesterday.

We have 12x 400W Hyundai panels (allegedly - they look a bit different from the photos in the data sheet or maybe it's just the angle?)

A Growatt SPH5000 inverter and 2x Growatt ML33RTA 3.3 kWh batteries.

Congrats on the new system!

I too have the Growatt inverter and battery similar to you with 4kwp panels as well as an iboost which was installed last week. My config is slightly different in that I have panels on both roofs as I am east/west facing. I find the system will first supply to the house with any excess charging the battery, where I usually have approx  50% left from overnight use, and then the iboost to heat the immersion cylinder. As a result I have hardly anything to export and sometimes struggle to keep the water hot enough without careful planning.

Thanks! These are all SW facing. Unfortunately I don't have a hot water tank as the old back boiler and fireplace were against a wall I took out to make the living room and dining room open plan, so I've exported 23 kWh since the panels went live at about 3 yesterday. I'm not begrudging other users of the grid some clean electricity, but I might if getting the SEG payment set up takes too long!
