Hi, my BYD lvs 8.0 will not charge automatically. All the settings are the same as on my other systems. The only time it will charge is when I manually discharge the battery for approx. a hour or so. Then it goes to 100% and after reaching this it drains slowly. I also tried a gridd code with ESS keep batteries full, no success.
Firmware 3.52. No solar. Setup as backup. Grid connected and only critical loads.
