          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.

          Perfect!

          Shopsolarkits set me up with a customized WHK3. We doubled the panels, doubled the inverters and doubled the batteries! The only parts I’m waiting on is stuff I didn’t purchase thru SSK! Love the fast response time to questions after the sale.

                  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.

                  Packed with Power!

                  We’re very happy with the Griz by Big Battery! We bought two of them and both of them are awesome powerhouses! They charge quickly and their power lasts plenty long. The shipping was great! Very well packaged and shipped quick! Thank you Shop Solar Kits! You guys are awesome!

                  Perfect!

                  Shopsolarkits set me up with a customized WHK3. We doubled the panels, doubled the inverters and doubled the batteries! The only parts I’m waiting on is stuff I didn’t purchase thru SSK! Love the fast response time to questions after the sale.
