Nothing to talk about? they just work? LOL. There are a lot of Voltronics inverters out there in service, I think the original (250v PV) MPP 6548's are pretty common set up. A few years ago they were a low cost of entry path, today there are far more options. I have no regrets, they were cheap...

Sub catagory to "Up in Smoke" could be... "Black And Blue" :ROFLMAO:

I am thinking that the 1000W string is no more safe than 4000W string if an arc is formed by a poor connection. Better to spend your efforts on good connections, fuses between strings and check the MC-4's once in a while, cables under the PV (under load) for unusually warm spots (that would...

I got mad and bought a ten-pack of 10mm sockets...and still can't find any!

The SOC reported by each of the batteries - never seems very accurate. They are relying on the BMS to calculate the SOC but the BMS doesn't measure low currents well, (or at all) and it seems the BMS SOC is only accurate once it triggers full 100%, I had similar experience, and nearly lost my...

I got an old wood-stove free for picking it up, and bought some black stove pipe. Hooked it up and got some HEAT into my Greenhouse since it is still below freezing at night where I live...in the North-woods. Now if there was only some easy way to trade my problem with @BKY2003 's we could both...

yeah, but that just makes it Soooo much more frustrating later when you KNOW you have two of them, but can't seem to find Either ! :ROFLMAO:

You may have read about it, back in ancient times, before On-Site-Power-Generation, they had to string miles and miles of wires on towers and poles to bring electrical power to each and every home and business, very complex and expensive systems...lol.

I have the same issue coming up with plans for PV expansion, 400 feet away, ground mount, my inverters are not high PV voltage DC - BUT WAIT! as one of the guys pointed out for me, there is no need to change inverters, you can just add a high voltage SCC for the new array and leave the rest of...

If you take the Blue pill, you go Victron and no Rabbit holes appear? But if you take the Red pill, you get some AIO and build DIY batteries add BMS's and then SA to get it all to work together...and spend three years reading posts on a popular solar forum, learning a ton about stuff you didn't...

It does take some guts to do this from the point where you have never used solar, and are adding up all the costs (on Napkin # 22) and then explaining to the "Offical Load Tester" why we need to spend 30 kilo-dollars (lol) on some solar panels 'and stuff' . without sounding like ya just lost...

Headline: "DIY Solar Forum consumes 60% of Swedish man's total energy" ;)

Interesting story, a fire safety expert once told me: If we just discovered natural gas today, it would be impossible to get it passed for domestic use in N.America today.

Yup! DIY Battery Building is Alive and Well ;)

From the picture and description - this could have ended very bad. Interesting to see LTO - from what I have seen these cells are expensive compared to LFP - why use them for stationary set up? just learning experience or was there some specific reason to use these cells? IIRC the LTO voltage...

Just blown away by the rules and regs, and outright manipulation. Try to imagine any other self produced item being charged like this: 'oh you grow your OWN tomatoes, we will need to set a scale up at your house, you will pay us for rental of that scale, and then we will weigh the tomatoes you...

But 20 Panels...sitting in a shed...would keep me awake at night thinking of where I could install them... :unsure:

Then I walk to the storage room, pull out a spare, and install it. At least that is the plan. I will admit I bought a 'spare' inverter, but once I had it sitting in the storage room, yeah, I installed it, put this to work. Other than the inverter, I have lots of spare parts. I do have an entire...

I have to thank @ADK Homer for starting this thread, it is a question that clearly was on our minds, 280-some postings on ! Like many here, I jumped into solar in a 'serious' way around 2020-21 when all the parts seemed to fall into place (AIO, LiFePO4 racks, low cost PV) and I found Will's YT...

That is the conclusion I came to as well. Shipping 16 cells in boxes is going to cost nearly the same for 105's vs 280's by the time the dust settles, a BMS is a BMS so it may as well drive the largest capacity cells you can fit in a suitable box. I didn't like the cost of the Seplos, so built...

DIY Racks, add one at a time, once or twice per year...53kW so far and growing! How often do we check on the solar? everyday!, only because it's fun.

My entire workshop is Lithium Iron Phosphate - operated, no cord to the utility!!

LOL Someone should start this as a thread: "what do you put on a solar enthusiast's T-shirt" /front of the shirt: What do you get for the man that has solar? /back MORE SOLAR

First Law of Thermodynamics - conservation of energy. DeltaU= Q-W No Free-lunch, there are no exceptions. if you could make a machine with zero losses, the best you could do is net zero; energy in = energy out. However losses are a reality, so energy in > energy out is the only possibility.

Lower costs for PV panels and equipment will not make your roof bigger, point it more southerly than it is already nor reduce the poor solar most of Europe has for the winter months. Ask me how I know. I enjoy a "Rainbows and Lolly-Pops" story as much as anyone, but remain firmly fixed in...

1. Not Victron = moves on 2. Too Long Didn't Read = moves on 3. Too confusing - not going to orgaize OP's life for them = moves on LOL = couldn't resist the temptation! :ROFLMAO:

Getting back to the OP original question: "would you go EG4 or something different" I ran some numbers based on our discussions of the Deye (Sunsynk) 8.8k x 2 plus the square D isolation transformer, and compared with the MPP 6048's I have (two) plus the cost to add in a third one. The Sunsunks...

I feel even 'those in the middle' can start small, an inverter and battery, use off-peak power rates for load shifting-only, to start. Put aside the monthly difference in utility electric bill towards adding a few PV panels - watch for used panels. Build up slowly from there. Join the DIY Solar...

I don't always check my battery pack voltages and delta, but when I do, I like to use Solar Assistant! :love:
