If you're getting to 3.45V / cell at float you're fine. Ignore the soc... It's not precise anyway. If you want real precision get a trusted shunt.
Oh no! I bet holiday has it all messed up. Hang in there I’ll bet they show up on 1/4. Not sure your area but I’ve had a lot of fun sourcing used panels in my area, and price per watt has been awesome. It’s so much less stressful going and picking up your own panels in my experience. I found this guy via Facebook market, he’s a used/new wholesalerWell after a month of waiting my two additional (final?) solar panels did not arrive as scheduled yesterday.
Amazon gives a new delivery date by 1/4/24. Refund if they do not show up. Arrrrgh!!
That’s awesome. Had the same thing happen today and charged my golf cart completely up, system still had a ton of energy coming in. When the sunshines it’s a party! Pretty exciting stuffYeah, well except I got no easy way to transport such things...
He we were talking about 'wasted' energy... just playing around a bit as my batteries approach full charge and noticing that earlier in the day I was getting max out from my panels .. about 3.3k and now a bit later only 1.2k or so... tried adding some load to the inverter (via an electric space heater in my office) and lo and behold the Solar PV Increased to cover it without diminishing the charging input to the batteries.
(and if I turn the space heater off the batteries keep charging at the same rate but the PV and Grid power drop).
Interesting, very interesting.
and needless to say I had not noticed/been aware of this but was suspecting it from just various observations.
That would definitely suck up some pv energy!
Could you elaborate on this? It doesn't make sense to me.Yeah, well except I got no easy way to transport such things...

Sbu. It's like the inverter is displaying pv 'used' not pv input.
The grid power part threw me off, it should be flatlined in SBU if the suns shining and batteries have a charge.
Batteries hit float voltage, working as intended.
Oops sorry... I said grid and meant load... Edited above....
Yes but my misunderstanding was that I thought the inverter would display the 'available power' but that really doesn't make sense now that I think about it. ?
Right it’s not really showing available it’s showing what the mppt is “accepting” ie load demanding right?
Right!
Good call
Yes, exactly. A battery just sitting there has unknown power available til you put a load on and measure it and you'd have to max out the load to know how much power it can supply. No way to measure it otherwise.
