So I've been quiet for a while because I've been busy on my project, which is moving slowly only due to life, otherwise it's moving well. But as I was studying my wiring diagram, I got to thinking once again about the idea of a master battery disconnect, which ideally I'd want but was told...

So 8 years ago I started dabbling in solar, and envisioned a portable self-contained kit that I could take with me camping, to festivals, etc. It would provide me power to charge my phone, inflate my air mattress, run lights at night, and anything else. I figured I could cram a battery, charge...

I'm a sucker for testing and data. I've seen a number of people post real pretty discharge curve plot graphs. I'm curious though what tools/software/means you are using to produce these graphs? I've love to do some myself. :) Bonus points if it's not Windows-only (I run Linux).

So unlike the current SBMS0, the older models (like my SBMS40) have the power coming off the solar panels passing through the unit before being sent out to the batteries. I'm unclear from the manual if there's a voltage regulator. 1) is there one? 2) if not, would there be wisdom in putting...

Hello! Now that I've made my introduction post, I can keep this one focused: I have an SBMS40 that I will be using with 4x EVE 280Ah cells in series. Together they'll be used as part of a portable solar kit, in conjunction with 120W (12V) panels and a 600W inverter. I've been exchanging many...

I'm usually good about posting in an intro forum when I'm new. :) I'm a hobbyist and native Vermonter. I've always been interested in electronics and have decent fundamental knowledge. I've been very much into solar as well, and being an avid camper (including going to music festivals) I've...

So this is my third iteration of a portable solar kit (camping, etc). V1 was really slick but way too small. V2 has been serving me well for many years but is ugly and disorganized, without a proper container and a mess of wires. V2 I want to size up further, switch to LiFePO4 and clean up the...
