OK, so this morning before sunrise I turned off the solar panels on my RV and ran some loads so at 1310 hrs the batteries were at 38% (26.4v). I then turned on the panels and the LV2424 fired up and started charging the batteries at 430 watts so I went back in the house for my covid-telework...
Strange things happen during the holiday shopping season. I have had them deliver to the wrong house more than once, and I have seen the tracking showing as delivered when it was not, only to have it show up the next day.
Bill you are absolutely right. I hereby withdraw my earlier comment, 12 volt is legit for many scenarios especially RV solar. I would stay with 12v in my RV but for a specific reason I need more power. I need to stay off this forum when I have a few.
As I have learned in a couple other threads, you can't rely on the MPPSOLAR all-in-one units to cut off the batteries before they discharge below the safe level. So in order to protect the batteries you need a good BMS or a battery protect that will cut off the batteries independent of the...
I found out when I was testing my setup that it does the same thing. When it shuts off the power, I have to manually unhook all leads, count to 10 then reconnect the leads to get it going again. I guess it is more of a catastrophic doomsday shut off device than it is a hands-off voltage...

I messaged the seller to see if this will cut off the power/charging when the temperature gets below freezing. From the listing it appears that is what it does, but I am not 100%. I will post what they say...
So I am still trying to find the best settings on the LV2424 to fully charge my batteries. As previously discussed, at around 40% state of charge (SOC) my LV2424 would significantly reduce the charging watts and the sun would start going down before the batteries were full. The smoke from the...
Thanks Steve, looks like Will is WAY ahead of me on this (as usual). So I guess I will wait until he tests the one the DailyBMS company claimed had low temp protection. The interesting thing about the listing I linked to is that this particular BMS seems to have a sensor that their other...
I am trying to figure out why the relay is attached to the 24/12 converter? I would think the converter connects to the BMS and then to the 12v fuse block.
I contacted Lion-energy and asked what settings I should put for my bulk and float, and they said set both to 27.8. I will try that next, but am not optimistic.
Look what mail-lady (mail-person?) Alejandra brought me today. It has 3 10AWG wires soldered in already. Google tells me that is equivalent to a 5AWG wire, so about 150 Amps.
Upon closer inspection I see an issue with the middle wire. How does the middle wire conduct negative return power? I don't see any metal connection???? How does this work?
How does that work???
