          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!!

          Works as advertised. Haven’t hooked up the solar panels to it yet as it is for emergency use.

          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.

                  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!!

                  As Described

                  Works as advertised. Haven’t hooked up the solar panels to it yet as it is for emergency use.

                  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.
