It puzzles me that you would not use the obvious solution, insulate. That takes care of cold mornings, and cuts out a huge amount of heat as well. Also with no radical temp swings, no moisture condenses. I have a 53ft by 40ft seacan shop with a central 30ft wide bay. Before insulating, even at...

I have a friend who lived for 2 years in a tent til someone gave him an old granary. He is solar powered. Another guy I know has lived 8 years in a tent in the arctic 45 miles from town. He lives on rabbit and ptarmigan. Walks to town in the winter when lakes are frozen. That is one tough SOB.

Sorry to hear this happenned to you, and all I can say is my dealings with Michael were honest, straight forward and the price was right. I have nothing to complain about. Some things are out of a sellers control, and with the shipping bungle up that is ongoing, I expect to see lots of shortages...

One source of wire most people forget is scrap yards. I've been a scrapper for years. Five years ago I bought a reel of brand new 1/0 copper 3 conductor Teck 90 armored cable for 1100 bucks There was 800ft on the roll and I have finally used it up. They sold it to me for the scrap price, about...

Here is an article that may help you, fHorst https://electrical-engineering-portal.com/how-dangerous-are-induced-currents-in-transmission-towers-and-poles

It's a laughing matter today, but a lot of foolish things we laughed at twenty years ago, are rammed down our throats now.

And if they are 12v each black box in the picture would be two 12's in series

Growatt maximum voltage is 147 volt, IRRc. The manual says if your Solar panels’ Vmp (Voltage at maximum power – the lower of the two numbers on your panel spec) (Not Voc) voltage is between 38.3 V and 57.5V, you can connect 2 in series with matching parallel strings to add up to the number of...

Congratulations on your success. I have been following your thread for along time now, and I have the same stuff as you, and it is good to hear of others doing it right

I think you took it wrong. No battery will ever stand the abuse a welder can dish out. The discussion I thought was about setscrew vs crimp. Im all for crimp. I have tried a bunch of stuff, and if air arcing out a weld and you feel cable getting hot, throw the stinger in a water bucket. I would...

I can't remember where I saw this but a simple window screen mounted in that box about mid way front to back will boost output. It's black and has a huge surface area to collect heat.

Do you have underground powerline feeding your house? Line leakage from a failed cable may be eating you wallet. After living in my 1958 house for 20 years, built when they could not spell the word warmth, I finally said enough is enough and got a modular home. Warm, spacious, we like it. We...

I'm with you on ground mounts being the best in our environment. But also I'm a big fan of steel roofs. In my case, with an almost always western wind, south facing means my panels are edge on to the wind. I've also learned to build my buildings facing gable end into the prevailing wind, and the...

Is your generator 120/240volt? Your power cord is feeding one phase of a split phase panel when on solar

You can hook as many watts to it as you want. The MPPT part can only use 7000 watts, but overpanelling allows earlier charging starts and later charging time. When the sun makes the array put out over 7kw, the excess is wasted unless you need it in the house. All inverters will use a battery to...

No. I am in Western Canada. This was imported into the Port of Vancouver. And these prices are in CDN. If I was in the US, I would not try importing from China. And I often think some of the grief members experience is from the action governments take.

For Growatt inverters I have dealt with www.watts247.com and think highly of Ian, and his prices are fair, and he is available on the phone, in person, and knows his shit.

At a scrapyard you can buy old welding cables for the per pound price, and lots of them are fair condition. All 4 of my 50ft lengths for my welder came from the scrap. Some places won't sell, you have to check.

I had no joy with the gov't website at all. I hired a broker and asked my questions and let them figure it out. What they told me was a small number and was encouraging. I have just received 20 Yangze 550 watt panels, and the whole transaction went well. In North America it seems that the 100 to...

No cost ideas at the moment. I am talking to them now, and it is such a new product that they don't know much, will get back to me. The two sales men I have talked to keep their promises and are clear on the phone to my crapped out hearing. They do call back. When I have anything to report on...

I will definitely agree on that.

Looked it up in the manual on page 8, it tells you that output is powered by the grid when the LED is green, green flashing is battery powered output. The Introduction says that input from a generator or powerline can flow through to the output. It can also have battery charging from these...

Good stuff on lugs. Welding suppliers have good experience with heavy DC current. Even good lugs at 250-300 amps will heat a cable termination up to the point that it will melt solder when doing steady high amp and high duty cycle. Most electrode holders are setscrew type and a while get too hot...

Never seen that sort of pile. I suspect that if you have frost down 1.5 meters like we do, that you would have heaving. I have included a drawing of what we in the west call screw piles. My house and deck sit on them It takes a Bobcat about 5 minutes to sink one 10ft deep and rotates 18 times...

Could you elaborate on that info a bit more, or some sources?

Or...you can have your BMS run a solid state relay like Chargery does to switch the DC load. That way the BMS does not handle high amp loads on a printed circuit board.

I don't live in the USA and we don't have tariffs to deal with, and the wily Chinese have figured a way around that problem. They explained to me that they do this for the US and would do the same for me even if not needed.

I got a call today from my contact at St Gobain regarding the PF100. His name is Richmond Powers and he has given permission to post his name and help the community. He can be reached at 949-238-0482. We discussed thicknesses and he is getting back to me on this in a couple days. He said the...

True, but we don't have tariffs. We do have import duties, and sales taxes, all based on product value, and I pay those happily. Product value is accurately stated. It seems to me that pissing matches between nations should be kept out of the consumers arena, and we should let the best product...
