Hi guys, i am using a multi 2 inverter charger for 24-volt batteries. Last summer I noticed that the charger was not charging in bulk mode. It was starting to charge but immediately was switching to absorption mode. The result was that the amps provided were low and unable to charge them. Since it’s a professional boat and there was no time for investigation, the electrologist recommended buying a new one. After installing it, was working great. Recently I noticed the same problem appeared. The batteries are in a good state. I updated the firmware from the application on my smartphone. Any ideas?
Loose wiring, tighten all connections, check fuses etc.
If you can get hold of an ir camera check fot hotspots.
