Chins 24v 150ah battery 1 year and 2 months old - connected to an MPP hybrid LV2424. Been working great for over a year. Low sun time of the year so hybrid inverter has been doing its thing to switch to utility to charge (LVD set for 22.8 - well above the Chins BMS) when not enough solar throughout the day.
The other evening my logs showed the battery at 22.8 so it should have switched to utility but everything just switched off. Voltage check on the battery shows 9.18 volts with no load. With no battery the hybrid inverter won't turn on - battery is so low a 24v charger won't even start.
Presume battery is dead? Sounds like an internal failure?
