The tracker has ended up powering our Bluetti (7.5kW total storage) power station. That pretty much covers all kitchen appliances, microwave, the air con and any other heavy loads up to 2.5kW. I run the lathe and mill from the Bluetti as well when we have plenty of power. House is still grid tied as never enough in winter, but March through October the house only uses 1-2kW a day. We don't sell back to the grid and using the Bluetti solves lots of regulation issues having solar dedicated wiring in the house. Pretty much just electric shower and electric range cooker only loads we can't power, wife likes to bake, so well worth the power used.
The Bluetti can handle a direct feed in from the tracker and make full use of the array. The 12V side maxes out at 600W per array, looking into moving to 24V replacing the Rolls battery. This is as much a hobby for me these days, it certainly isn't a fit and forget system. My workshop rack is a lot of work compared to the Bluetti. The all in one is very convenient, and portable, I would certainly say it's the way to go if you are starting from scratch.
Apologies for the awful picture of Bluetti stack, AC200L and two B300K expansion batteries. Wife really likes this system and took to using it straight away.
