My system leaves a lot for expansion. Your system likely uses less idle power and is far less expensive. You could use used Tesla batteries/with BMS for a far far less costly system. I was too worried about burning my house down. Agreed that my gasoline car is more likely to cause a fire than the Tesla battery/BMS.
My system has a lot of room for expansion due to ability to run lv2424 in parallel, and ability to feed more into that transfer switch... up to 4 x lv2424. I may be locked into 24v, though, with lv2424, whereas you are set with 48v.
I really love the flexibility of our transfer switches, making that side a once and done deal. I'll hook up all 10 circuits right away (shorting L1 and L2). Just can't obviously flip them all on gen at the same time. When I add a 2nd lv2424, one will feed each L. With 4, you'd have 2x lv2424 on each L.
I considered the LV5048. It is the better option if you don't mind the bigger up-front cost. The LV2424 can handle up to 2 kWh PV, though. I need to discover what kind of return I can get on that before I consider expanding, being in Ohio.
It sounded from what others said in another thread that I'm not paying a lot for grid, either, at 0.13/kwh. Combined with NE location payback is a challenge. Scaling depends on how practical payback is, and that is going to all come down to how much I can get in a year from the PV.
I do consider UPS a plus; so if I can break even in 7 years with the batteries, that would be one heck of an achievement. But UPS isn't just how much you can store in your batteries. The solar panels are UPS in a prolonged grid downtime as we'll be able to produce at least some energy on most days.
