Wrenches, l have both single and 3 phase residential systems over a 100 k and we used the largest SMA's available and now 15 years later they are starting to fail so fewer bigger more efficient inverters are a plus. Now with PG&E NEM 3.0 Batteries are the only way to store and use later, and then throw in the elimination of N.G. in California heat pumps are it and along with electric ranges both at a big demand of the system, 25 k is a good starting point. Fun times,
