Delivery: Ok, not very fast, but ok. Quality: Ok, but not as specified. 3/16 Cells are uncpecified, not HiNa, Capacity not as specified. Design: Good Service: Ok Tested all of the cells.

There is no good Inverter which can handle that range of 32-63.2V, even Victron has 38-66V which dont cover the 6V on the lower side...
