Has anyone here tried using high voltage electric vehicle (EV) batteries for home energy storage? I'm curious about what inverters are commonly used for this. I've noticed that salvage EVs often come with undamaged batteries that have double the capacity at half the price compared to standard home batteries. While I understand this might not be feasible for everyone, I have some experience with handling high voltage systems safely. Would love to hear your thoughts!

There’s definitely more to think about if you're considering this. It’s vital to know if you'll have inspections for your setup and whether you're on-grid. How large is your installation going to be? And how comfortable are you with handling these kinds of systems? Also, are you planning to install it indoors? That can change a lot.
I never thought of using salvaged EV batteries before, but it makes sense for budget-conscious folks! Just remember, though, that working with high voltage carries serious risks. Make sure you know what you're doing or stick to safer options.
I actually use secondhand Nissan Leaf batteries for my home system. Instead of keeping them at high voltage, I dismantle and reconfigure them to run at 56V for my 48V setup. I'm actually moving to a different country soon, where I plan to switch back to using the high voltage batteries with some Fronius equipment at my new place.
