    about to wire up 2x mpp 2424, lifepo4, solaredge autotransformer and 4.5kw of panels. sanity check?

    so a year ago I decided to build a small (2kw) system for my RV that turned into me reselling about 200 solar panels to fund a larger system. in the process we bought land that had grid power already, so I've been able to take my time. --------------- things I have on hand: 2x mpp...

    RaspBerryPi 4B Cases that support HDD/SSD (NEW DeskPi-Pro), [! BAD DEAL !]

    Gotcha, I don't have a interest in having a 3d printer either. Too much tinkering, I always just have someone local print stuff for me. Plenty of people will print things and ship.

    RaspBerryPi 4B Cases that support HDD/SSD (NEW DeskPi-Pro), [! BAD DEAL !]

    You might want to look at "odroid nas" cases. They should accommodate a pi. Check thingiverse for appropriate STL's

    Off grid refrigeration

    It's just thermal mass. If you want to move the water everytime you need something out of the freezer or have it crush everything under it, by all means put it on top.

    stage 1: Lv2424 CALB 100ah Chargery system running

    looks great! I am sitting on a mpp2424, 48x 120ah lifepo4 cells, and four bms8t's I'm considering going with victron inverters instead, for the ability to use grid power AND battery power at the same time.

    ISO inexpensive 48V inverter for test bench

    you may want to list location, incase someone is near you. does the UPS not have an option to set a custom cut-off in the remote management config? you could get a low voltage disconnect board from ebay and tie it to a large relay, like the ones chargery have started to use. if you're near N...

    How To: Mount Panels to an RV Roof

    Great write-up. I'm following someone that is re-roofing a rig just like mine (97 newmar DP) and am considering doing the same thing. I have so much to eliminate (horns, antennas, vents) and it's got some soft spots. Gotta find a tall barn to rent for a few weeks. I want as much solar as...

    FREE: Large UPS battery cabinets (4 in Atlanta)

    Awesome. I'm gonna be in Atlanta this weekend but I have no need or space for something like that. I am lusting after that pile of battery cables, but I'm just a copper junkie I think. Assuming this is a setup at a datacenter. I need a new case for my NAS, got anything kicking around that might...

    Chargery V4.00 update

    Just for people apprehensive of doing the update: I upgraded four bms8t's and their lcd's last week painlessly. Followed the guide on chargery's site. I put the main unit and lcd images in different folders just so I didn't cross flash them. Hp 840g2 laptop, W10 x64 fully patched.

    Ali Express feels so shady - but do I have a choice buying LiFePO4 batteries?

    this is true in my experience. I ordered 48x 120ah cells from Luyuan, painless process.

    No, local pickup only. There's plenty of panels available in your area. Sunelec is the major supplier down there.
