Solis RAI-3K-48ES-5G charger, with Fox-ESS LV5200 battery.
Latest problem, battery has stopped charging. System was "disabled" around 3 weeks ago by disconnecting the grid meter signal whilst investigating a totally different issue, today I reinstated the grid meter. Battery is at 74% SOC, I'm currently exporting over 1.3kW to the grid, but the battery won't charge. So far, I've checked all programming settings on the Solis, done a full power-down and reset on both the Solis and the LV5200 battery, all BMS settings are as they should be. I changed the time on the Solis to put it into timer-charging mode and it still wouldn't charge... time now back to normal.
I applied a considerable load, to "force" a discharge, this dropped the battery to 72% and when I removed the load, it started to charge from the available solar. Yes, I thought, it just needed to do some sort of internal kick-start, but then when it got to 74%, it stopped charging again!
I previously had a problem of the Solis giving an alarm and tripping off-line when any reasonable load was applied, with the message "ACOvercurrent". Weirdly, when the unit self-reset after a couple of minutes, it would ramp-up to match the load without further issue. Today, when I applied the loads, it worked properly and didn't trip out, but now I have this charging fault.....
The Solis software on my PC shows the inverter and what it's doing, but it isn't showing any information for grid , battery or solar power....
Anyone have any clues??
