Hi, I hope someone could shed a light on this problem. I installed a new system in 2020 which consists of 3 Battleborn BB10012 and tracer BN solar controller along with the AiLi monitor. It worked absolutely great until we left the boat over a 6 month period. I disconnected the batteries at 88% charge and shut everything off. On my return I reconnected all the batteries and powered up. Batteries on the monitor showed 87% which I thought was great. However it appears the actual AiLi monitor isn't working. The percentages don't change at all and there is no >+ or <- indicator of showing the charge or discharge. All the wires are correctly installed the same as when it was working before. I've tried disconnecting the display unit from the shunt but it's still the same. ANY IDEAS?
