Holy cow, where do we start... $149,000 of batteries... are they unaware of other options on the market today? 12V batteries in series? Yikes...

🥳🥳🥳 holy cow that's a lot!

Just was shown an ad for this product a few minutes ago: https://battlebornbatteries.com/learn/products/lithium-power-pack/

This always annoyed me and I found a solution. Now you can browse through pages of the forum without scrolling all the way to the bottom.

Man these things were expensive, but the install was quite easy. They absolutely need more pictures and someone to rewrite the manual though. One of my condenser units had a coresense logic module, so I had to connect it to an off-grid system 240V supply, fire up the Bluetooth and change the...

If you have interest in EMP hardening or protection devices that mitigate the effects of an EMP on a solar system, check out the new section! This new section is a sub category listed under the solar system category: https://diysolarforum.com/forums/emp-hardening.91/

When I first saw these, I thought they were rewrapped ev cells to make them look flashy. Do you guys know anything about this company? I haven't heard of them before:

What do you think? I like them. Think about how easy an off-grid system is if you threw this on the ground in your backyard. Excited to see more of these come to market:

These guys are using basic rich solar panels in various configurations to increase overall output. They stated that most radiation is not absorbed when first hit, so anything that gets reflected gets absorbed by the adjacent panel. I tried to get some figures for overall increase of output...

How long have we wanted something like this for?! They claimed a 10 year warranty without any leaks. Very new company it seemed like, with current installations being pretty small. Super cool to see!

Snagged some photos:

What would you like to see? This thread will be seen by myself and a few other YouTubers, so let us know what you guys want :)

What would you guys like to see in a video covering the ep cube system? What would you guys like to see tested? https://www.epcube.com/

https://www.nextbigfuture.com/2024/01/ev-lfp-battery-price-war-w-55-in-six-months.html I hope we see some of these price decreases for stationary storage LFP! But check out the comments. An individual shared this opinion: Alexthinks January 16, 2024 at 10:12 pm This is not good news. The...

Not as fun as last year! I think everyone was sick or jet lagged ? RE+ solar conference was better last year. Looking forward to that one. Here are the pictures I took:

I had no clue these exist! Instead of wiring up a transfer switch or critical loads panel, you can run your entire home off this thing: https://www.generlink.com/ Imagine how easy it would be to run a house with an off-grid solar system with this unit. The biggest downside is they only...

"The California Public Utilities Commission (CPUC) is soon to vote on a proposed decision that is expected to be harmful to the value of rooftop solar for renters in multifamily housing, farms, and schools. The decision would disallow residents of multi-meter properties to consume their own...

New Section for DIY Solar Forum! I was browsing through the forum nodes today and felt like something was missing... Heat pumps! If you need to heat or cool a space with solar power, check these devices out. Super efficient method of moving heat with power generated by an array directly or...

Solar Assistant is a solar system monitoring and remote control app. It can also be used for home automation and load control. I am using this poll to measure it's popularity on the forum. I have never used it before, but am curious how many people are using it.

Very unique panels. I couldn't find many benefits listed on their site for these "elite panels", and the max wattage was 430W, but they looked so cool! Check out the current collector on the backsheet. They looked really cool in person! Here is the datasheet...

So currently, DEYE, Voltronic and Luxpower manufacture our favorite large off grid inverters. And at this years largest solar conference called RE+, everyone had relabeled units from these three companies. So my goal this year was to find a competitor. And I think I have found one. Chint Power...

Today I headed back to RE+ to get some better pictures of this thing. It is massive! And heavy. If you were to make a 16S 51.2V battery with these cells, it would come in at 421 pounds! I also took pictures of their other cells: EVE LF 100MA: EVE LF 280K And the LF 306K:

RE+ is a massive solar conference. I've gone to it for a few years now, and it keeps getting better! This year it is happening in Las Vegas. For those of you attending, what are you most excited to see? If you are not attending, what do you think I should check out or get coverage on? This...

1. Ignore Content If you do not like a forum (for example, solar water pumps), you can hide the entire page from your interface! This can allow you to clean up the forum to see only the content that you are interested in. If you ignore a group and wish to see it again, this option will be...

I have had zero interest in reviewing or testing their batteries because they seem overpriced for the features and capacity. It honestly looks like a $400 relabeled battery for the price of a battleborn or Discovery. Am I missing something here? I've read the spec sheets multiple times and I am...

I didn't realize it until last night, but I think this battery is pretty sweet. The look, form factor, busbar with quick connectors, communication ability, internal heaters, outdoor rated and the list goes on. Now I want to dump my server rack batteries. Which one would you rather have. This...

In our server error log, I have been getting "max user connection" error. Just figured it out yesterday. The SQL database had a limit imposed. I increased the limit, the error is now gone. I was confused because there were no issues with the actual server. It was in the server log of the forum...

Just saw this article posted: https://www.pv-magazine.com/2023/07/07/using-existing-fences-as-near-zero-cost-racking-solution-for-pv-deployment/ Would be fun to see how many sun hours I could collect in a day during summer versus winter. I suppose it's good if you have piles of used panels...

You guys will love this. I took some high definition pictures of the inverter they are using at this massive installation. And it gets even better. I found a broken 250kW Tesla charger near a transformer! Check it out:

Yesterday I ran a few polls to see what the customer support satisfaction was between Sol Ark and Signature Solar. I was expecting Sol Ark to have zero complaints, but more people had issues with them than with signature solar! To sum up the results: Signature Solar- 19% of voters had an...

Cast your vote above ? you cannot see the results till you vote. One vote per individual.

What do you think? I threw it together in photoscape this morning. I am thinking about adding top contributors to the donation list below the mods. There are incredible people here who spend hours helping others. What do you think? Is the banner graphic decent? If you have a better graphic, I...

Each row is a string. These two strings of panels are in parallel and connected to victron MPPT. You can see that the last panel is shaded: 420VDC. So plenty of voltage and the last panel in the string is shaded, but only producing 200W for both strings! Now wait 30 minutes.. The shading...

Typically I do not get excited over heat shrink, but today I think I found my favorite. It is lined with adhesive and when it cools down, creates an incredibly strong connection between two PV wires. This is for those of you who prefer butt splicing their PV cables instead of using MC4 for PV...
