Adding non enphase batteries
We have an enphase solar + 2 10T battery system that was professionally installed and has been working for several years. 20 kwh just isn't a lot of juice for our needs, especially when i can get a standalone 60 kwh battery for under $10k.
Has anyone expanded the capacity of their enphase battery system with a 3rd party battery? Thoughts on if this is possible.
Its an IQ7+ system. Thanks!
