See pic: The first (long) spike is the fridge starting. It's AC, draws from the inverter. The second one is the water pump. DC, draws directly (well, it goes through a distribution panel) from the battery. See, even though the first draws a lot more amps, the second causes a bigger voltage...

Considering the amount of absurdities I keep seeing in galleries being passed off as "art", I thought I'd do my own. Kidding aside, the "trends" section of the SmartShunt allows for some rather good looking and interesting graphs. Please post your own if you have nice ones. A cloudy day...

I shouldn't have installed it so close to the vegetable patch ;·) * * What I grow in the vegetable patch is classified under section III of the None Of Your Business Act of 1661 ** ** Issued by Donalt B. Zilly, Elector Palatinate, who was certifiably insane. Section I: Shut up and mind your...

It has recently come to my attention that solar panels in the U.S.A. cost at least three times what they do in Europe. Considering that taxes on consumers goods there tend to be less than half what they are here, panels are mostly made in China - therefore cheaper to ship to America than to...

1. The pressure meet terminal must select and use appropriate terminal specification first being put into use coordinating the correct implement again when being put into use (Probable) translation: use jaws of the same size on both sides. 2. Revolution retinue pressure model arrives at correct...

I recently got 8 280Ah cells from Shenzhen Luyuan (Amy Wan). Grade A-. They looked good (very well packed too). No dents, no scratches, no swelling. But, one cell goes over voltage. It's not the BMS, the cell actually does. Voltmeter confirms. Switching cells order doesn't change things. It's...

I just got my 8 280Ah cells from Shenzhen Luyuan (Amy Wan). Grade A-. They took 83 days from order to door. And the parcel people made a mess so I had to go and pick them up (60 km. from here) twice. But, apart from that, I'm really quite happy... so far. The packing was really good. Made to...

I got 4 of my 8 280Ah cells today. DPD obviously stands for Donkey Parcel Deliverers, as they didn't tell me they would deliver 4 one day and 4 the next, did they. So I'll have to go back to Palma (60 km.) tomorrow and get the rest :·/ The four I got were all exactly at 3.382V. Quite...

I've been thinking about converting my 240V fridge to 24V. It's not so much consumption that worries me, more noise. Anyway, I'm almost ready to experiment. I got me a used fridge (so I can try it without giving up my current fridge yet), I'm looking to buy a Danfoss-Secop compressor. Thing is...

Well, it seems to me slightly out-of-place that in the US they would use something as simple and straightforward as international electrical measurement units. As there seems to be no place for anything sensible like the metric system in the ex-colonies, I hereby propose the immediate adoption...

I have a 24V water pressure pump. It works just fine, good pressure and all... it just cut in and out a bit too frequently for my taste. I did buy an accumulator tank for it, with... pretty dismal results. Even after setting the correct pressure - a bit of a trial-and-error process, my car tyre...

Unlikely, but you never know... I have a CCC (Cheap Chinese Clone - Must PV1800 VMPK) that has been working quite well for almost a year, but... I'd rather be safe than sorry... if it does blow, I'd rather have a spare one that I bought cheap than having to spend (quite a bit) more to get one in...

I really have searched here and pretty much everywhere... the more I search, the more confused I get. I asked for a 100A BMS with active balancer for 8s (24V). The vendor suggests a JK-BD6A20S10P. $65, which sounds good. Except, it has pins for 20 cells, not 8. To connect the remaining pins, is...

Epever Tracer 3210 AN. With which I am quite pleased. Every now and then, my ammeter on the output of the controller goes to zero. After a couple of minutes, it resumes charging normally. How often it does it... it's not as if I'm watching the ammeter all the time :·) I do watch it quite a bit...

A suggestion more than a complaint... even though I do find it slightly annoying having to scroll up and down to check who the OP actually was - I don't have much of a photographic memory, and not many people bother with avatars anyway ;·) There is a Xenforo plugin that will highlight the OP in...

So, apparently the cells in my Pylontech LFP batteries look like this: What are they? Pouch cells? -

...the Victron SmartShunt. For what? The Most Annoying Software/Hardware/Firmware combo of the 21st century. :·/ Hardware: decent construction, pathetic Bluetooth adapter. It's not just that it has a short range, it's totally temperamental even when showing 5 bars out of 5. (Cannot connect -...

Maybe we could/should have some sort of "incentive" for people to put their location in their profile? It would save a lot of "depends where your array is located" questions and.. all that :·) One forum I'm active on, gives access to some "restricted" areas based on that, but maybe just a plain...

Traditional ones anyway. I just wired up a bus and a house. Used remote control switches for everything. No wires needed- except for power. You can get them cheap, DC, AC, anything. With multiple transmitters. One-channel, multi-channel, anything. Smartphone-activated, voice-activated...

This has been addressed before, but no satisfactory answer was provided - that I can find. Say an LFP battery has a life expectancy of... 5000 cycles. Pretty good as it is, but... say one never "cycles" it. There's no real reason to do so either, is there? From what I understand, a cycle is...

LFP, 220 Ah (two 110s in parallel). This is off a Victron SmartShunt. The orange (current) spikes are the fridge starting. Almost no voltage drop. The blue (voltage) spikes are the water pump (it's 24V, draws less than 2A, doesn't spike - it goes through an analog ammeter, I can "see" it. So...

I have a SmartShunt. I use Victron Connect on Android to monitor it. All it's really good for is giving me a rather precise (I guess) voltage and amperage reading, but it's OK. Problem is, I rather dislike pocket computers (smartphones). I'm old, my eyesight is not what it used to be, I like...

So, that is the controller I have. I tried the PC app. Over RS 485 to USB cable. Took me ages to get the COM port settings right, but I managed that. I set my parameters. It said OK. User mode appeared in the charging settings - I set it to that. Next day I got some sun, it went to 28.8V (I set...

Pretty easy... ;)

(I've asked Mother Goo...gle, but I' can't seem to find any useful information). Just as the title says. No matter how well you treat your phone's battery, two-three years is what you'll get out of it. And it seems no one expects it to last longer, either. My phone's battery easily lasted a week...

Installed a smartshunt some... four hours ago. Yes, bluetooth range is abysmal. There are workarounds, but, hey :confused: Apart from that, it's not making much sense is it. I wonder how long it will take to start doing so... ;·)

Obviously a "solar parody" of Monty Python's Galaxy Song :·) The choice of words and semi-rhymes is meant to to keep it close enough - and above all, vaguely assonant - to the original. Just a boring Sunday morning, really ;·) Whenever life gets you down, Mrs.Brown And things seem hard or tough...

I need some pointers here. Just installed a new battery. 110Ah, 24V. It's a Pylontech UP 2500. Not much sun today - well, not constant, charging it at 15-20A - with plunges at around 5-6, when clouds obscure. discharging almost nothing. SOC, it has 4 LEDs. 3 are lit. According to the manual, it...

Temporary accommodation. We're building a little house. Being temporary, I didn't waste much time on fine points. I just took the seats out, put some floorboards and some stuff from the ex-house in. Water I get from a neighbour (he sold me the land, he's an old friend). Now that was the...

I've almost decided to get a Pylontech UP 2500 battery - 24V, 110 Ah. It already has a BMS in it - with leds for display. If I wanted to add something "visually pleasing" in the way of BMS... like PC software or Android app... how would I got about it, and what is out there? It has RS485 and...

Simple problem: I like analog ammeters. I have one between the panels and the charger. Nice to look at, gives you nice to read information. I have one between the windmill and the (separate) charger. Absolute bliss to look at - when you have wind :·) I have one for 24V loads... er well. Just...

I'm seriously thinking about buying two of these (to make 24V) https://batteryfox.es/product/ultimatron-lifepo4-12-8v-200ah-smart-bms-con-bluetooth/?lang=en A few questions: - Does anyone know anything about those? They're French. I can't find any reviews for them (which doesn't mean there...

Sorry for the double post :·/ I somehow got confused.
