I have a 3.6 inverter with a 10.6kwh battery and 16 solar Pv’s that can produce 6880kwh.

Any advice would be much appreciated.

That battery should be able to take 200A DC at 48V. I don't know the maximum the Inverter can do on the battery port. Disable grid charging and the 32A breaker won't matter.

Currently only charging at around 1.8kw/h from solar or grid, so would like to charge a lot faster when solar is producing plenty. Not an issue at the minute in November as not enough sun to make a brew! :-D

I'm making a few assumptions, and you may have to correct me or fill in the unknowns. I'm understanding that you have a 3.6kW Sunsynk inverter, the model sold in the UK with the 7kW MPPT.

If so, it should have a max charge rate of 90A, or around 4.5kW.

Does my 32A breaker on my consumer unit for the inverter prevent me from setting my charge/discharge rates higher than 32A?

If you've been keeping your charge amps setting to 32A for fear of exceeding the grid supply, that's nothing to worry about. That would be 32A at probably 230V, or around 7.4kW. Just set the inverter's charge setting to 90A, and it should top out at 4.5kW, whether from grid or solar.

Right now if you are only achieving 1.8kW of power from solar (or lack of), that's maybe understandable on account of sunlight, but experiment with grid-charging to confirm that you can reach that 4.5kW or 90A from grid.

Perfect! Thank you so much for your advice. Not being any sort of electrician, just needed it confirming. Didn't want to blow the house fuses! :-D

Wish the installers had as much interest in the system working as efficiently as possible as they did in making the money to install it!

Pointless having the system if it is not set up correctly, thanks again everyone....
