    automatic transfer switch

    I see, so in the last example I'd just set it to turn on below 12v, off at 14v. Perfect. And waay cheaper than the MOES.

    automatic transfer switch

    Thank you. One thing the MOES does is once it switches to the grid, it only switches back to the battery once the battery has reached a set higher voltage. Example: If I set its lower and upper voltages to 12v and 14v, it will switch to the grid under 12v, then stay on to the grid until the...

    automatic transfer switch

    Well… I bought a MOES a while ago, but sounds like it’s time to rethink that. I have a small 12v solar/battery system, with a 1200 watt inverter and 110v grid power (I’m in the US). To replace the MOES, could I get the 110v version of this relay? And I plan to replace my Renogy 10/20a PWM...

    Considerations when using PVC conduit to run off-grid solar cables through side of detached garage

    I've been distracted by life but I'm back on this project. I'm doing some more brainstorming now. I think I'm going with 3/4 inch galvanized steel EMT for the short conduit run outside. - For the 'electrical box' / conduit body that will be mounted on the outside of the garage, I currently...

    Considerations when using PVC conduit to run off-grid solar cables through side of detached garage

    Yeah, I'm leaning towards keeping it above ground at this point. It seems the most ideal in my situation. And it's sounding like I should do galvanized metal for all the conduit both on the house and on the ground - my biggest hesitation is just the increased costs.

    Considerations when using PVC conduit to run off-grid solar cables through side of detached garage

    While the building does have power (separate from the battery power that I will use independently), I believe it is considered an 'accessory structure' and not a habitable space. I live on a flag lot, and I believe the house in front of me sold the property behind it and this building used to be...

    Considerations when using PVC conduit to run off-grid solar cables through side of detached garage

    So it sounds like I should use EMT for conduit on the roof/building, then do galvanized or stainless for underground. It's a very short run for the underground section - less than 15 feet. Shallower trenching would be nice since there's some cement slabs AND tree stump in the path that I'd...

    Considerations when using PVC conduit to run off-grid solar cables through side of detached garage

    Yes, I could do metal conduit for the roof, so the conduit coming from the roof into the side of the electrical box could be metal, and the conduit I sketched coming down vertically from the electrical box could be PVC. This is a northeast facing wall that doesn't get much direct sunlight, so I...

    Considerations when using PVC conduit to run off-grid solar cables through side of detached garage

    Hello, I’m planning a small solar setup connected to a battery. I want to run 8 awg solar panel cables into my detached ‘garage’, which is a small non-livable 10 ft x 20 ft building, which has its own power but I’m NOT connecting the solar system to the grid, i'm just using a transfer switch...

    Identifying a legacy(?) rail mount system to find brackets/bolts/hardware

    So the guy who gave me these rails ended up finding a few of the original clamps. If anyone has any insight into what these are called or where to get them, that would be great. Particularly the bottom piece that fits into the rail (the upper part I'll probably have to change anyway). I have the...

    Can we get a solar system that doesn't feed back to the grid + sizing advice needed

    Say you had the AIO but no batteries or solar - so you were just running the grid power through it. What's the efficiency of that? is there any energy lost when the AIO is supplying grid power directly to your home? I assume if it's not converting to DC it would be minimal, but just checking.

    I just took a ride in 2022 Tesla

    I'd still like to have one, but that's been my complaint with Tesla.. Considering electric engines are so much simpler than gas engines, that shouldn't be the case. I wish someone would do an electric car built to last, with redundancy and fixability in mind, with mechanically...

    Identifying a legacy(?) rail mount system to find brackets/bolts/hardware

    I got ahold of these old solar mount rails. Since, correct me if I'm wrong, it appears these won't work with the current standard z-brackets, mid clamps, etc (seems to be too wide?), I'm wondering if anyone can identify what these rails are called and maybe a place I where could find all the...

    CATL 271Ah 'Grade A' prismatic cells from Shenzhen Basen - Cell terminals without threading

    Here it is so far. The compression case was inspired by other people's work in this forum. I might put a surface across the diagonal part and put my monitoring display there. I'd like to add a fuse as a precaution. Is the best place to put it on the negative side between the load and the BMS...

    CATL 271Ah 'Grade A' prismatic cells from Shenzhen Basen - Cell terminals without threading

    Results of the capacity test were 272 Ah / 3479 Wh from the aliexpress tester, and 3530 Wh from the shunt. The shunt (and the BMS app if I remember correctly) also consistently read a few .1 volts higher than the capacity tester. Whichever is more accurate, I'd say that's satisfactory. The...
