- I ran the BLUETTI EB3A down to 1%! In this video, I found out how long it takes to recharge it using a 100w (4x 25w) solar panel.

Pretty disappointed with my EB3A. I wanted to use it to power some 12V LED shed lights that incorporates a motion sensor. That way when I opened the shed door the motion sensor would turn the lights on & I have it set to turn off after 5mins of no motion detected. I connected a 100W solar panel to top the battery off and thought I was set. With the EB3A's 12VDC turned on it used about a third of the battery power. So I disconnected the shed lights, charged the EB3A to 100%, turned the 12VDC on & left it for 24hrs. With no load attached it drained down to 68%. I contacted Bluetti and they claim that it wasn't unusual to experience "self-consumption" like that. So a couple of cloudy days & "self-consumption" will drain my EB3A whether I go in the shed or not. I'm curious if your EB3A has the same self-consumption too? Thanks for allowing my vent.😂
What I’ve found is I need a very sunny day to get the eb3a to charge. Yes, just leaving it on consumes power. I suspect this is due to the Bluetooth and whatever else is going on in the battery. It does seem to work well when on and connected to something to run it. And, when it’s off, it consumes nothing. For this reason, I’d recommend going with a LiFePO battery for a dedicated circuit like you’re describing.
@@TheGergeDIY After 3-4 days of research I've come to that same conclusion. I was just looking at batteries & charge controllers... got to figure how much self-consumption a charge controller will have, choose a battery with/without BMS built in, 100Ah enough? All the reviews/forums never seem to have these same concerns. I have come to the conclusion that Bluetooth isn't necessary for my application but I'd like an LCD display to monitor the battery. Ugh, I'm making a mountain out of a molehill with this project. Thanks for your time & reply.
I make many mountains out of projects. :)
