LL-S review

I received an LL-S as a warranty upgrade. my original LL-2V had a bad cell and these had just come out..... I love everything about it.... the touch screen lets me see the cells are balancing. I do disconnect my panels once a month and let the battery cycle down as living in southern Arizona I'm never under 50%. battery cycles down and shuts off at 19% each month no problem..... glad I paid a little extra and got the display

Very well designed

As a technician I really like the design of the rack and easy way to assemble the batteries.

response to shortage from factory.

Sig Solar responded without hesitation to replace missing items in each box containing the EG4LL batteries. Very good start in working with Sig Solar.
