Thought this was interesting that is specifically excludes energy storage systems: https://olis.oregonlegislature.gov/liz/2024R1/Downloads/MeasureDocument/SB1596/Enrolled (iv) Is a system, mechanism or series of mechanisms that generates, stores or combines generation and storage of electrical...

This looks like a great paper that would be valuable to a lot of us but I do not have access to the full paper and wasn't going to spend the $30+ for it. It will be freely available on Sep 27, 2024. The publishers site does still give some interesting info just from the little bit of...

I think Arizona is missing big opportunity in not advertising the fact they don't change time every spring and fall. This time change just totally messes me up and my wife.

Any reason why I can't use a "valve box" as an underground pull box? Doesn't say "electrical" on the lid but is less than half the price of one with exact same dimensions that has "electrical" on the cover.

What would be recommended labelling for combiner box on a ground mount array as well as the conduit from combiner box? Was looking through PVLabels.com and wasn't sure what exactly should be used. This is not an inspected system but would like it to be appropriately labeled.

Does someone have recommendation for a brush that can screw on to one of those telescoping poles with the "standard" screw on end? I have this pole. They have a scrub brush that is 11" wide which is pretty narrow and didn't know if someone had a better recommendation. There has been a LOT of...

Missed this announcement and thought it interesting to share: https://us.qcells.com/blog/qcells-north-america-completes-dalton-factory-expansion/

Just thought I'd document someone removing utility company from their place that has it already and will go completely off grid. I'm at the end of the line on this particular spur of utility lines. A large part of this is not directly related to financial aspect of this but environmental...

Finally! and at worst time of year for trying to do this. The little still showing up is because I still have some house wiring that is trickier to move over to new panel. It looks like they shared a neutral for what should have been two separate circuits. My electric co-op is also very...

Is there a source that I can use that will tell me what the expected cloud cover will be? The national weather service in the USA is terrible for this even for basics. Today for instance was going to be cloudy when it actually turned out to be sunniest day we had in a long time and was able to...

Just got email notice about this. Looks like another rebranding of the LuxPower: https://www.altestore.com/store/inverters/hybrid-inverters/renon-power-renon-power-flex-12kw-hybrid-inverter-p43186/ My email says you can use a code RENONFLEX for $500 off as well.

I have a battery bus where all batteries are connected to. From there there is a positive and negative 4/0 copper going to busbars about 7 feet away where the charge controllers and inverters are connected to. That 4/0 battery cable is currently protected by a 250A MCCB that disconnects both...

Anyone know exactly how to wire the https://www.shelly.com/en-us/products/shop/shelly-pro-1pm? I can't get 120V AC reading on the output terminals and think I must have it wired wrong. I have Neutral and hot wired on bottom and the Neutral and hot "output" out of the top. The unit is powered...

What would be the best way to control a 40 gal. 240V 4000W electric water heater? I'd like ability to configure it not to run at night and possibly not run if not generating enough power for the day. Was possibly thinking of some Shelly relay that can trigger a 2 pole relay but not sure if...

This has come up numerous times where almost all of the DC rated switches you see for sale aren't actually rated for over 48V DC. I believe I actually found one that comes in 400A, 500A, and 600A versions...

A lot of times threads start veering off topic because someone wants to reply to something that was mentioned that isn't specifically related to the original post. A nice feature would be if there was option to start a new thread from a REPLY which would make it easier for individuals to keep a...

I currently have my EG4 18kPV setup as charge controller only. Two interesting things I've come across that I haven't seen mentioned yet. - If you turn off all AC output the idle load drops to 16W-20W. - If you limit the PV output to 100A the fans were not on. As soon as I raised that to...

Just in time for these relentless cloudy days. Producing about 800W at 10:30AM local time with this solid cloud cover.. enough to actually start charging battery bank again which is now at 37%. 30 480W Q.PEAK DUO XL-G10 on Sinclair mount. Connected to a EG4 18kPV which is only being used as...

I just connected an 18kPV to a new PV array and for some reason the charging output to battery from PV array keeps ramping up and then you here some clicking noises in the unit and it resets to zero output. Wait a minute or so and it starts all over. This is an off grid setup with no AC in or...

Looks really interesting. Who is going to call and find out how much it costs? :LOL: https://wrightenergystorage.com/summit/

I'm having trouble believing that these Langir breakers are actually rated for 20A at 500V. Why do I see no other breakers available anywhere else that come close to that price and voltage rating? I've seen a lot of people using those as 300V+ disconnects in PV combiners/pass through boxes and...

Just thought this was interesting simple test. These are 480W Q.PEAK DUO XL-G10. Had it laying flat yesterday sometime around noon and at 47.5°N latitude. I was somewhat surprised by the amount of shade from cables and tester still on panel and still got that result.

Sort of interesting to see what happens:

This sharp point (on end where the clamp is attached) on this Sinclair ground mount is going to cause a serious head gash at some point during its lifetime ? so would like suggestions on what can be put on the end of this to prevent that. Protecting just that bottom edge at least would be enough.

Looking for recommendations for wiring enclosure and components inside to mount on a ground mount array. This is for 5 separate PV strings that will all have separate runs back to the charge controller. Max Voc would be 450V. What I was thinking so far is: Vevor 16x16x8 metal enclosure 5...

Some passive strip that can be applied to bottom of even old solar panels to help clear snow off automatically. Not exactly sure how it works or what it is.. but requires no external power source. Currently being tested in installations and supposed to be available for sale next year...

I'm a little confused how to wire the red square area and each ? item. Can someone explicitly list what goes to the ? items. Thanks. Assume @timselectric would know :)

I have two Quattros configured as 120/240. One provides L1 and the other L2. Would it be possible to have L1 of grid power connected to the AC In of the Quattro providing L1 and configure it to grid assist that leg only? I would like to have more load capability on that single leg only...

I ordered 25feet of 2" flexible metal conduit from HomeDepot online to be shipped because the local one did not carry it and told me I'd have to order online. Lo and behold when it arrived there was nothing inside besides paper padding. The box had been re-taped (I'm guessing by UPS, there was...

Is @Will Prowse or @HighTechLab going to https://www.re-plus.com/ in Las Vegas?

I'm adding a 2nd Victron Quattro 5kVA for split phase output and also an unfused transfer switch. The transfer switch will then feed the main breaker panel. The transfer switch will be used to switch between the Victron system and a separate off grid inverter. Do I need a 2 pole circuit...

Where can I get filler plates for panel mount breakers? I moved a panel mount Midnite 175A DC breaker to another location now have a large opening that needs to be replaced where it was. Do I just need to find a "universal" filler plate? The opening is 1.5" x 2.3".
