Asking for a friend 😎. Obviously a US centric question but with all the threads on what does/doesn’t count I’m wondering if anyone has been audited for the tax credit. If so, was it a question of producing receipts, pictures, or an agent conducting an on site visit ? Inquiring minds want to...

I thought this was an excellent video about what can be done with the Luxpower setup which I think is like the 18kPV often discussed on the forum. If I’m wrong about them being basically the same hardware I’m certain someone will correct me 😎. I have no affiliation with any of the companies...

No idea how long it will take to get to market, assuming it does, but this seems promising : https://www.uottawa.ca/about-us/media/news/revolutionary-breakthrough-manufacture-photovoltaic-cells-university-ottawa

Coming soon in a few different variants. See one example here : https://www.solar-electric.com/victron-electrical-panel-5kva-120-na-follower-48vdc.html

So I have been thinking about this idea for a while and many posts from @fafrd about GTIL's (grid tied inverter with limiter) have helped quite a bit. I still have a few questions for the group. First, some background about my system. I have pulled a number of circuits from my main panel over...

I’m no tax expert but I believe there are a couple new rules to get the 30% tax credit for batteries. Specifically: The batteries must be at least 3 kWh. I don’t recall seeing that in years past. And the most surprising one: THE BATTERIES MUST BE 100% CHARGED BY SOLAR ! Don’t EVER use...

More specifically, parallel battery wire resistance which is approximated by wire length. I have an older EG4 100Ah 48V nominal battery that I plan to parallel with a DIY battery made of 16s CALB 100Ah cells. I have about 3 feet of 2AWG on the EG4 to the busbar. On the DIY, the situation...

Some months ago I emailed Amy@DocanPower.com asking if they had come out with a Server Rack type battery. She said it was in development but not available and I asked her to let me know when it came out. They now have one and it looks like it will sell for $1500 DDP to USA, plus some...

For wire routing reasons I would like to mount a DC DIN rail breaker upside down. Other than code compliance and possible operator confusion, is there any other reason not to do this ? Specifically a C65H DC Breaker like this ...

Still working the bugs out on this alpha unit :

I am looking to help a friend come up with a way to convert his pool pump to solar, it is currently on grid. The pool is around 20,000 gallons and has a 1.5 HP 240 Vac pump with a sand filter. The location is sunny Tucson Arizona. If the pump only ran when the sun was shining that should be...

I happened to see this and had not seen it mentioned on the forum : https://watts247.com/product/growatt-lifepo4-48v-rack-mount-floor-standing-stack-able-100ah-4-8kwh-battery-with-bms-comms/ Listed as “in stock”. I have no affiliation with either company.

Here is the latest and greatest from an industry in its infancy : https://boattest.com/electric-outboards-metstrade-2021 Quite a range of products, very low production numbers at this point in time. Some include batteries, some don’t. Just “x” out of the signup page and you will be able to...

These are usually packaged in 40 foot shipping containers for deployment : https://www.seattletimes.com/business/technology/oregon-companys-iron-battery-breakthrough-could-eat-lithiums-lunch/ Using a proton pump to manage the electrolyte was a major breakthrough.

Like tens of thousands of other folks who viewed Wills latest video on crypto it got me thinking. I noticed a mention of NiceHash by him and thought of starting there. In a few minutes, I set up an account and put to work a computer that is not being used during the week. The computer is a...

So I have a few SmartSolars connected to my iPad no problem. I’m at a remote site trying to connect to my iPhone. Downloaded the app no problem. Entered 000000 for the Victron no problem. My iPhone keeps asking for the code displayed on the SmartSolar SCC before it will connect. of course...

This wouldn't help supply chain/shipping issues if it gets worse: https://www.cnn.com/2021/06/14/politics/china-nuclear-reactor-leak-us-monitoring/index.html Only 85 miles from Hong Kong. Yikes! More solar power please.

When I brought up the Tiny VNA months ago some folks found it helpful. Here again is a product in the $50 range that won’t replace a multi kilobuck analyzer but it does a crazy good job. I ordered one from here April 29 and it should arrive this weekend...

You can charge to full capacity at 3.5 or even 3.4v. It’s a long video but see here:

Is anyone aware of a small mini-split? Say 5,000 BTU? I have a 20 foot off grid shipping container that I spend some time in on occasion. It is located in Arizona so there is a surplus of solar energy and some brutal temperature swings. I basically just want to take the edge off a freezing...

There have been a number of threads and discussions about inverters and transformers for the US 120/240V market. Some of the discussions are with Victron equipment and Victron transformers, some with other stuff. To be honest I have a hard time following some of the use cases. Here is one...
