    How to Find Happiness with an Off-Grid PV System

    Ah! I think I see what you mean - the Low Voltage Disc/Rec settings listed in the first two (SOK Recommendations) columns are backwards, i.e., Low Voltage Disc = 11 , 22 (for 12V and 24V systems, respectively) Low Voltage Rec = 10 , 20 Is that what you're referring to? They do appear to be...

    How to Find Happiness with an Off-Grid PV System

    We do have above-ground tanks, kept full with rain catchment. We're in the process of tying them into our water system to supplement the well water. Would a small, inexpensive 12V booster pump be capable of pressurizing a house plumbing system? Nope. The pressure is needed to keep pipes from...

    How to Find Happiness with an Off-Grid PV System

    If you mean lower settings for the Low Voltage Disconnect and Reconnect, lower settings would allow the battery go to a lower SOC (e.g. Low V Disc = 22 would permit discharging to less than 5% SOC). That would not extend the battery life cycle. The main thing for extending life cycle is keeping...

    How to Find Happiness with an Off-Grid PV System

    I confess I'm pretty new to solar - especially small, off-grid systems. I'm always open to suggestions! What settings for those parameters seem right to you?

    How to Find Happiness with an Off-Grid PV System

    We rely on well water. Last winter, our beloved utility company suffered a prolonged power outage (I believe the polite term is “Electrical Disfunction”). Without electricity, the 115V AC jet pump that pressurizes our plumbing did not run. No electricity, no flowing water, the pipes froze, and...

    Two 12V BMSs in series vs One 24V Charge Controller

    YES! Excellent points. Especially regarding manufacturers' extreme settings, often mimicked by their consumers. I've learned a lot since my original post, and I'll be posting my empirical experiences soon. Thanks, Mcgivor!

    Two 12V BMSs in series vs One 24V Charge Controller

    Here’s what I’ve got: Two SOK 100AH batteries in series for 24V Epever Tracer4215BN 24V 40A charge controller w/MT50 Giandel 3000W pure sine wave 24V inverter Four Rich Solar 100W panels in series (total of about 90V) It’s time to program the Epever. I’ve done a lot of digging around...

    Source for wire

    Hi folks, I'm new to the forum (and diy solar in general), and maybe you already know of this place, but I use an online source for wire called Wire and Cable Your Way (https://www.wireandcableyourway.com). You can purchase any length of any kind of wire you want for very competitive prices...
