The battery arrived in a wooden box with a pallet matching its size, in excellent condition, along with factory test documentation. Very good build quality, beautiful, and heavy. After two months of use and several tests, I’m very satisfied – it works perfectly. Before ordering, talk to the seller about your inverter model. In my case, with the Solis 6kW Hybrid Plus, there was no official support, but after many adjustments I made myself, they work together flawlessly. For Solis inverters, choose “Lithium LV.” If that option isn’t available in the menu, connect via Bluetooth using the Solis app – you’ll definitely find it there. Thank you.
