Hello All, The facts are: 1. 3 new AGM batterys, rated at 110 Ahr each. Normally charged by a multi stage charger 2. The power meter reads 390 Ahr for the 3 of them (not 330 as expected), and is very accurate measuring the load in and out 3. Above 295 Ahr, the batteries do not charge by the engine alternator Below 295 Ahr batteries charge OK by the engine alternator 4. The Solar Panels (2 x 100W) do not seem to charge the battery at all, no movement from the meter That’s the real concern. They are connected properly, when connected directly to floodlights (to test them) they work. They increase the voltage of the batteries up to 13.6 on a sunny afternoon, but have no effect on the Ahr reading. How can this be? Any clues on resolving this would be greatly appreciated.
