Maybe, but you cannot know for sure. I happen to have exactly the same question, and would have done the same. Notice the OP did not add external links, he just pasted in the photo with specs and brand name. Nothing wrong with that surely!
I found the same thing @snoobler posted up above. I checked with my supplier about swapping out the 1 battery for extra solar panels but that may not be possible since the order has been prepared already. I also checked the SMA Sunny Island specs (see 17.3 DC Connection for Battery) and found...
Thanks a lot for the info-I'll have someone take them all out and measure the resistance correctly! The problem is that the thing is at my project site in Kenya so sending it out your way is prohibitively expensive. I will bring it back to Europe with me next time I go though-and check with you...
Hey hey, I am doing something very similar for my family house down in Kenya. One piece of unsolicited advice to you however would be: get the precision stuff/brains of the solar project from well known makers in Europe/US. Do not take chances with that. With my project, I am getting the...
Please reread my post. To clarify:
1) I was never offered free replacement. Items under warranty ought be replaced at seller's cost in full, especially in the event of outright foulplay.
2) They offered to *partially* replace the faulty batteries if and when I bought more from them. No. I have...
Thanks Toms! Yeah, I am attempting to create a DC coupled system like the one shown here. What I find confusing is that the configuration does not appear to be supported in SMA Design tool- checking again to see if I can add SMA SIC50. I also thought that the sunny island had a charge controller...
I see the Kilovault balancer you linked will draw up to 10Amps from the higher voltage battery. Victron balancers on the other hand will draw a maximum of 0.7Amps. I am guessing the Kilovault and other such balancers will correct imbalances quicker. The difference is huge though, why is that?
Hello Folks,
I have been looking for for an international supplier (preferably in Europe where I live) for the Victron Easysolar 5000VA/150 MPPT for my solar project in Kenya. I just cannot find any reputable suppliers that will sell and ship over there. I have been through Amazon Germany...
I spoke to the current contact person on their Alibaba page (Daisy) and they told me that these were no longer in stock. Is there any reason to shun used cells, especially if they have been tested and the IR+capacity are good and matched?
I would not mind used cells that are well tested and...
Oh yeah, that's definitely a great idea. I am aware of the SOC~lifeExpectancy relationship. I would have preferred to have it in the bank though- just so that the whole bank ages slower and I have a bit more usable capacity. I will research a bit more on the 60V bank possibility but I was...
Hello folks,
In my battery bank setup, I have got four identical 12V LiFePo batteries connected in series into a 48V bank. Each battery here has got its own BMS i.e., the BMS's do not talk, each does it's own thing. As you might guess, the first battery to charge up goes open circuit and so the...
They did refer me to their distributors map, and the two appointed distributors already in Kenya. The trouble is, those two Kenyan distributors are not folks you want to deal with: total joke.
Thank you! The prices are pretty close to Alibaba rates for each kind of ware I think. I wonder if anyone here has bought from them (Sunpal) and what their experience was, and also wonder what folks make of europe-solarstore.com . I am also looking at @upnorthandpersonal post on his experience...
Oh Yeah, the whole package was delivered some weeks back. Everything is in order. I am travelling down (to Kenya) to do the installation next month so I will update this post shortly after. According to my folks (its them that received everything), all items are in tip-top shape and I saw the...
Hello, thanks a lot for making this point. I intend to use the Victron Easysolar 5000VA charger/inverter unit. I just revisited the datasheet and see that the 150V/100A charger it comes bundled best works with 24V/48V banks, which it will auto-detect. I see no mention of 60V banks in there, only...
Yeah, but for Kenya, customs is much improved since they started ending the paper era. Charges, taxes and the clearance processes are clear but the permits you need to bring in what is where the real headache is. Branded, pre-assembled batteries would for sure be easier for an ordinary Joe to...
Depends on where you are though. My project site is down in Kenya. Certain things are difficult or expensive to get or ship in without much fuss with customs. Then again, I am yet to get to that gangster level where I build my own battery packs :-) :-). If I knew a seller that's got such units...
I disagree. The myriad serious issues users are reporting speaks volumes-and Growatt have not climbed to #1 on account of quality. Just tart by Googling "Growatt inverter reviews", then head over to Youtube and read comments below videos of their products (including non-promo real-life test...
Thanks a lot for the input!! Actually the project site is in Kenya so we are talking 240V/50hz. How do the "new in-the-box" Sunny Boys and Islands come about? If you have any links to some websites, I'll certainly have a look. Also, my system is pretty small: 6KW. The system you have got is...
I am in the process of shopping for an off-grid inverter and was just wondering, what is the difference between the Growatt SPF 5000ES and the Growatt SPF 5000 HVM-WPV counterpart? I see the two are from different series and the datasheets' first page would appear to suggest that the ES line has...
Thank you very much- I was looking for the same thing and it had not occurred to me to check with the official storefront. However, the suppliers own front probably deals with bulk orders for dealers around the globe so a 1-order item might not inspire the best in terms of the quality of...
Hello folks,
I am having some trouble decoding the technical details of the cells in the attached photos. These are BYD, but the serial number does not appear to follow the modern naming convention as with EVE cells for example. According to the guide here, the number of digits should be 19 or...
The panels are working like a charm, this is 9 months down the line. I had zero visible/physical errors with the hardware itself. The electrical perfomance is right at par with the advertised specs for 400W half-cell panels. I have 10 panels configured to run at 100V/40amp. 6 panels are still in...
Hello Michiganman, DO NOT touch SUNPAL. Their panels are fine (so far for me) but they are as dishonest as these outfits get. They sold me old, end of life batteries that were disguised as new at the price of new. Cliché right? I will write this up here soon. I repeat, avoid them like the...
Very good point about the system's modularity and ability to limp along when something fails.. The Easy Solar is in fact quite modular: you could literally piece it apart into the usual components. It's just neatly boxed up..
Wow, at 0.09 volts you are at serious death ranges for a lithium battery that is supposed to operated nominally at 48V. It could be that the battery died or got irreparably damaged, then the Gwatt is unable to charge. The Gwatt should have had a low voltage cut-off where it shuts down all load...
I wanted to share my experience here, mostly for the benefit of others to ensure nobody else goes through the horrible experience I had with Sunpal Power Co., Ltd, Hefei, Anhui, China, a seller I found on the Alibaba platform (see link to supplier profile). If this sounds like one of those "do...
