This took some doing! My system is configured not to export more than 4kW and I’ve implemented a power reduction strategy on my Solar Edge inverters to achieve that. One the battery banks get full, if I dont use the power somewhere then the inverters will automatically scale back production.
As I’d recently added additional solar capacity I waited for a forecast sunny day. Overnight before, I force discharged my batteries down to about 10% so that they would soak up much of the solar the following day. This only worked to a point, as by lunchtime I was having to use as much power as possible. Dishwasher, washer, dryer, immersion, lights etc. It seemed to work - just to prove a point.
I’m sure that an imminent EV purchase will help use the extra capacity. My real objective is to alleviate the winter months - which I guess you can only really do by having excess capacity in the summer?
Point proven, I wont be doing it again that’s for sure.
I know the difficulty when you have 12kW coming in and you need to have enough dump loads or empty space in the battery to stop it all curtailing. You have to plan the day before based on the forecast, on the day is too late.

Getting an EV will definitely help you absorb more of your generation for sure.
Maybe what you could do is advertise your EV charger as open to the public (for a fee, via one of the plug sharing apps like Co-Charge) and see if you can generate some additional demand?
