It's been running for a few days and so far it's going great, powering the whole house.

The batteries have arrived and were neatly and securely packed in wooden crates and styrofoam. It was quite a task to get them into place since they are heavy, but with the help of colleagues, we managed. The quality of the batteries seems good, and the materials used are of high quality. Various accessories were also included, such as a mobile trolley for placing the batteries, the necessary cables for daisy-chaining multiple batteries, a manual, and RS485 cables for communication with the inverter. The battery voltage is as expected. My first impression of these batteries is that they offer excellent value for money, and I am inclined to order more from this seller. Overall, I have a very positive experience.
