Mammoth Battery is a beast ...

Of course the Mammoth battery is a beast and it's amazing. But the gem here is the Shop Solar Kits support team. You're getting multiple decades of knowledge wrapped into a single offering. I was having a wiring problem and they not only sent me a diagram but also built me a Combiner Box ... who does that anymore? That's 'old school' / 'amazing' support - wrapped around an innovative product suite. Simple AMAZING ... got job Shop Solar Kits!!

Using 2 to power my house

I would prefer a third, but these two do everything I want. Only about 20 cycles in, but going strong. Easy to install and the bms is all internal and very simple. It does require attention, as they don't drain equally.
