I currently live in my van which is outfitted with 400W of solar, a Renogy Rover 40A charge controller, and a SOK 206aH battery. Had a few days of cloudy weather and the battery died this morning (reading 0.7V on the charge controller). The sun has since came out and now the charge controller says the battery is at 1.4V but gives no indication that the battery is being recharged.
The battery has overdischarge protection and the Renogy charge controller says it has a function to awaken dead batteries, but I’m uncertain if the battery is permanently damaged or if there is something I need to do to get my solar system to charge the battery. Any help would be appreciated
