Thank you for the help! The batteries have definitely been exposed to non optimal charging. Living in variable climate, and winter far north, it's hard to get them charged fully everyday. I will evaluate how the system manages from now on with different charging/usage behaviour. Then see what...

When I took the picture shown in the thread start, no. No load bigger than 4W.

Hmm.. Interesting! So I could just disconnect the extra array by the MC4 parallel connector and the 300W will work on its own? Will look more in to this. Hahah yea would be a pretty big mirror and I am already short of space in the car! Also imagine hoisting it up on my roof ? I passed this...

Yes it power meter can measure how much the system is using. I've just been very naive, since before installing the inverter it has never been a problem. So I have not looked much at the power meter. I'll have to calculate how much power I use per day. I study out of my car now and use a display...

Thank you for your very instructive answer, I learned something new! My knowledge in this area is very limited. I checked in to a campground this evening for shore power. I guess I will have to be more careful with my usage, for some reason I thought the system would have no problem keeping...

It's an AGM 12 battery (Data sheet). SSC settings: What I don't understand is why the voltage is so low? Should it not be around the "boost charing voltage" 14.4v, when it get sufficient power from the panel and the battery is not full? The panel is mounted flat on my roof so I never get...

Sorry I accidentally published the post to early, please check back for the edited version. It's an EPEVER Tracer 3210AN (A series 30a) While troubleshooting I have reseted MPPT to default "Sealed". I can't remeber the exact settings before, but I had increased the boost charge to better...

Hi! In short: I have issues with my MPPT that does not output sufficient voltage for charging. Solar panel seems to be working fine, but the MPPT does not up the voltage to more that 12.6-12.8. (See image, end of post) What could be wrong, perhaps is the MPPT broken? Background: The system is...
