  • The small setup I have now is based on this so I currently have to manually move where things are plugged in, but the 10 KW inverter I just bought is a hybrid one.

    It’ll charge, invert, and load balance automatically and there’s configuration you can program to set the cutover levels, charge/discharge limits, whether it should prioritize power the loads or charging the battery, and such. It can also mix utility and inverter power and switch between the two pretty seamlessly (10ms switchover which is comparable to a UPS).*

    *According to the data sheets, anyway. I ordered it today and wont’ have it until probably close to end of the month.


  • How many kWh a month do you use?

    Depends on the month as everything except my furnace and hot water heater are electric. In March, when the furnace barely ran and didn’t need any ceiling fans, etc, I used 391 KWh and my bill was $105 for the privilege. In July when I have to run the A/C almost constantly, I use close to 1,300 KWh and don’t even want to say what that costs me. I work from home, so I kind of need to keep it comfortable all day as well as run my WFH office gear. (Otherwise, I’d bump the thermostat up until I get home in the evenings)

    I’ve also got a homelab, but I’ve downsized it enough over the years that it’s down to ~250W continuous (yay USFF PCs! I used to use old rack servers that were 200W each).

    Any youtube channels you’d recommend? Other resources? Advice?

    I’m more of a hands-on learner, so mostly I’ve just played with it in different forms for 6 or 7 years and started small or Googled specific questions i had. The main thing I learned is that on a good sunny day, PV is like a waterfall and you often only need a glass of water from it. Unless you’re going grid-tie to absorb the excess, storage (batteries) is important otherwise it’s just wasted. The rest I guess I’ll figure out as I get this one up and running. As far as the electrical work, I grew up helping my grandfather on jobs (he was an electrician) so other than referring to NEC for some specifics, I’m pretty comfortable/confident with that kind of work (doesn’t make it any less of a pain in the ass though haha).


  • Nice!

    Back atcha. 19.2 KW would be amazing and probably way more than I need, but I don’t have near enough south-facing roof (sadly, I have plenty of north-facing roof. With these 200W panels I have, my back of the napkin measurements seem to make my limit about 6 KW on the roof. I may check the measurements of the 320W ones and see what that gives me, but I’m thinking it’ll be close enough that it’s not worth the extra cost.

    I do have plenty of back yard, though, so after I get this up and running, I may do another string or two as a ground mount setup.

    Grid-tie was my original plan, but power company has too many hoops, restrictions, and red-tape to make it worthwhile. Plus, I still need a backup power solution (e.g. a Generac) so I went ahead and got some big batteries right at the start since I was already planning on spending about that same amount for the generator + installation.



  • Maybe I can post a parts inventory or something and some highlights from the install.

    I’ll definitely be taking pictures as I go if nothing else than for having a reference of what goes where. The PITA part is going to be moving most (all?) of my circuits from the main panel to the new panel I’m putting in on the other side of the basement. The PV inverter(s) will feed that panel and distribute them out. Main panel (too expensive to move) will then just have a few 60A circuits running to the PV inverter(s). I’ll probably also throw in a bypass switch so I can isolate the inverters for maintenance and whatnot.

    If grid tie is an option for you, I’d recommend that if you’re just looking to cut your electric bill. It’s technically an option for me, but the electric company makes you jump through so many hoops and red tape that it’s just not worth it. Plus, I also want this to work “off grid” as a backup power solution in lieu of a whole house generator.


  • It’s been pretty great even with this little setup I have now.

    I’ve been wanting to do this for years, so I finally justified the cost of the big system I just bought by combining it with my need for a backup generator. I could stretch 30 KWh of battery to about 2-3 days even with no sunshine to top them up. I may still get a small generator as a backup backup just to charge the batteries, but I won’t have to spring for a Generac and having that plumbed into the gas and wired in. Plus those don’t seem super reliable as both neighbors who have those always seem to have service techs coming and going.












  • OpenLDAP. Have been running that as the backend of several of my services since 2015.

    I use it for authentication/authorization, either directly or via Authelia, as well as the backend storage for my DNS, DHCP, Kerberos, email servers, and a few internal / self-built applications. I even registered an official IANA PEN so my custom LDAP schema are properly implemented. It’s setup with a 4-way multi-master replication strategy and highly available via two load balancers in different data centers (plus one locally).

    Runner up is Nginx as I’ve been running it for just as long or a bit longer, and it also underpins most of my services in some way (at least as the frontend proxy/WAF).


  • My coffee hasn’t kicked in yet, so this is as diplomatic as I can phrase it under current conditions:

    Both are entrenched identity politics instances (“aNaRchISM!”) and a good chunk of the calls for violence around here are from users there. You’ll be over here trying to have a rational discussion, and someone from there comes in like the world’s dumbest parrot who can only say “Bawk! Guillotines! Bawk! Luigi”.

    dbzer0 was aight when it was just the piracy instance, but they’ve shifted more to far left politics and re-federated with Hexbear, so they’re basically Hexbear-lite these days. Quokk turns a complete blind eye (or tacitly endorses) several power users who do nothing but call for violence, doxx, and/or do nothing but spread anarchist propaganda.


    • Shun the toxic people. Block them and don’t look back.
    • Seriously, block them. They’re still gonna toxic whether you’re there to observe it or not.
    • Find a well moderated instance that isn’t afraid to show toxic people the door
    • Block .ml, grad, hexbear, dbzer0, and quokk.au
    • Block any other instance or person that centers itself around identity politics
    • Block all the news/politics communities. Just get your news from actual news services. The comment section for most news/politics posts here is worse than an entire garbage dump on fire.

    And you’ll end up with like 3 federated users left which is basically my /all feed now 😑
