I finished installing my array this fall and following is a review of this mount and install. I purchased the MT Solar Top of the Pole mount in a 16 panel configuration. When purchasing the mount, you go to the MT Solar website, there is a calculator where you input panel sizes, number of...

Currently on day 5 of no sun, finally turned the heat pump off and turned on the furnace this morning. Battery is currently at 21% and we are using about 1%/hour. I finally turned the AC input on to the inverters, breaker has been off since March. No laundry, no dryer, no dishwasher ran in the...

First photo is general view of components. Positive and negative busbars. 200a breaker goes to inverter, ANL fuse to fuse panel and 40a breaker on far left is for the buck converter. As this is a 24v system, I was able to use lighter cable as it was quite tight with tight bends in various...

Just looking at some figures, I turned my system on in mid March 2023 and used 13,666 Kwh since then. My grid usage in that whole time frame was 256 Kwh which comes to 1.87% of total Kwh thus far. As we are now past December/January, this might actually decrease over an entire year. They...

Going on day 3 of no sun and no real PV yield. My battery is 54Kwh. First day with heat pump on we used 32% of the bank, yesterday used 28% ( I did see some charging for about 10 minutes) and this morning I just left the house and down to 31% but sky is brighter today. Official Loads Tester did...

Update on the Big Blue Box from over a year ago. https://diysolarforum.com/threads/house-system-battery-box-hoffman.32305/ It's been a long process, I do not have much free time in the summer and this fall the array and EG4's I installed with some additional work done in house. A year ago in...

Hi everyone, been lurking in the shadows and finally decided to put up my first thread and post. I've read thru many of compression threads and can say there is much discussion about this subject. My background is automotive, I'll just leave it at that. This is how the EV manufacturers are...

Interesting video, surprising results

Finally got around to installing the Emporia in the shop. Had everything cleared out this morning around 9 am due to some communication problems overnight. Not even 12 hours elapsed and I can see a waste. West light and east light circuits each have 8 fixtures comprised of 6 bulbs per fixture. I...

Interesting news regarding isolators and solar panel fires.

My panels are generating over 60Kwh per day now. House is at 80°F during the day, I'm running a pair of 1.5Kw resistance heaters plus the heat pump. I'm still getting to full charge by 2 pm. This morning I was up before daybreak, turned all the resistance heaters up all the way and heat pump...

I have 2 of these charge controllers, one was installed over July 4th weekend, the other unit was installed late July/early August. The first MPPT has worked flawlessly, no problems. The second MPPT started to set a F01 code- Bus soft start failed after 2 weeks of use. This was right before I...

I'm going to consolidate some of the Daly Smart BMS questions into one thread concerning initialization and parameter setting, some of it I found here in odds and ends, some I discovered on my own. First off, thanks to those who pioneered ahead of me and found ways to get these to work. I...

Certainly interesting concerning the riv nuts. I built my Big Box and ran busbars down each side. I never took a photo of how the cables are attached. I simply used a stainless carriage bolt and cold headed a square hole in the copper busbar using my shop press after drilling a 5/16" hole. A...

Alliant Energy sent out notices regarding proposed rate increases starting in 2024 and another in 2025. Iowa's Governor had signed legislation with certain requirements of utility proposed rate increases and Alliant is filing for a non standard notice so it won't have to meet those requirements...

[Moderator Note: This discussion has been moved to its own dedicated topic, from a post where it was distracting from/tangential to OP's post, and derailing the conversation. And also an example of less-than-excellent communication on both our parts. Rather than deleting any content, its been...

Hurry while they last at this price, additional $40 off with the coupon. I was intending to build a pair of batteries with cells for my boat but for this price plus $40 off, I can use those cells elsewhere...

Hot off the press, system overview and general information.

I've been looking at a BMS for my 48V system I'm installing in my house. I'm seriously considering the Watchman CORE with Cellmate K9. https://www.batrium.com/products/watchmon-core-k9 I'm looking at the CORE with 2 K9's as I have 32 280Ah LFP cells, 500a shunt. In research, I ran across this...

https://www.kisaepower.com/bic-launch/ Wow! Wish this had come out sooner, looks to be a nice unit. Automatic transfer switch included and has Powerboost for twice the surge watts.

I guess you can abuse the SCC with PV overvoltage, then post a video on the internet blaming the inverter is at fault?

@timselectric This one is for you, the SPF5000ES didn't quite work out in the end. Love his comments concerning Signature Solar.

Recent post in a thread prompted this post, hope you like it, this is how I use poron foam for cell compression. I've charged em both ways, started snug (loose fit) or with poron foam compressed 25% and in 16P configuration, straight line of cells, both in parallel and series. The amount of...

Something for solar freaks, it's part of a video I'm working on. Took this on yesterday, December 29th, 2023 after 8 continuous days of no sun. 4240W per string, one string per each EG4 MPPT 100-48HV SCC's using JA Solar 530W panels in 8S strings. Foggy in morning until 10 am, only 49.03Kwh...

Interesting video after lightning damage

Anyone out there have this MPPT charge controller? Wondering if it shuts down when PV isn't available or if it has an idle draw. Link: https://signaturesolar.com/eg4-solar-charge-controller-mppt-500voc-100a-mppt100-48hv/

I've been looking for AC to DC charger for my trolling batteries which will be LFP possibly 12v 280Ah x 2 DIY batteries. Trolling motor can run all day and want a charger that can put out some serious amps. Prefer waterproof design. I did look at the IP67 from Victron which charges at 25A. Is...

Many here know I already have one MT Solar mount for my array. The recent purchase of the 370W pallet of 31 panels requires another ground mount. I submitted what I wanted to Sinclair and Kyle passed it on to the engineers. I asked if I could pickup at their loading dock as they are only 7 hours...

Will started a review of the Sol Ark in a video but I seem unable to find any follow up to it where it was installed and tested. Was there a second video ever created?

Ran across a deal on a large Hoffman electrical box for $200 on Craigslist. I've been looking for something to house the two 48V 280Ah batteries I'm currently building for use in my house. I wanted something that was enclosed, could fit 16 cells long in a series string so it had to be around 49...
