Live and learn indeed, just from writing up my own experience with Sunpal batteries..sigh

I'm curious, how did you find out the inverters were rebadged from elsewhere?

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...

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...

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...

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...

I recently purchased this JBD BMS here at the IC GOGOGO Aliex store and I am currently locked in a refund tussle with the seller. Seller is unsurprisingly unwilling to replace or refund. I would like some assistance diagnosing and fixing the problem to see whether repair would be the best...

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...

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...

I am looking at these ones here to expand my storage-what do you think? There doesn't seem to be much user feedback out here on all these 400-500ah cells : https://www.alibaba.com/product-detail/500Ah-Lifepo4-Lithium-ion-Cell-big_1600337159436.html?spm=a2700.9114905.0.0.MWNROo

Hello Aslan again, after about 8 months of use, I am having serious problems with two of the five batteries I bought. From my discussions with Sunpal, it looks like they will not honor their terms of warranty, and are offering to add two new batteries "with my next order" i.e., pay them more...

How sir? I cannot find this use case in Batrium docs and how-to's..

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?

"Your imagined solution does not exist."- this is what I really needed to hear.- I thought I was not searching properly. I was holding on getting Victron balancers thinking I might come across some magic solution in the form of a 4s, 48V balancer. I am familiar with the other workarounds of the...

For those of us already with 4x 12V LiFePo batteries in series, what BMS can we use to manage the whole bank? I suppose it would be a 4S, 48V one but I cannot find such a product anywhere, any leads?

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...

I would rely mostly on customer feedback to decide. Do as many inquries as possible, check their reviews on Alibaba, also check other sellers and compare, good luck!

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...

Just in case you missed this: A number of Growatts have recently been recalled in Australia over electrical/fire safety issues: https://www.solarquotes.com.au/blog/growatt-inverter-recall-mb2162/amp/

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 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...

No, the reports are from people that bought brand new straight from Growatt or from very well-known authorized dealers. Alibaba is just fine:There are very many reputable sellers there-and they are easy to separate from the chaff using the usual techniques (check reviews, whether they are a...

There are far too many reports online of malfunctioning and serious safety, quality and operational issues with Growatt inverters for me to trust the brand or product. I went with Victron and I am very happy so far-especially with their VRM monitoring portal-Growatt cannot match that.

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.

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 understand, - but this is not the inverters fault. So, yours is running perfectly huh? How is the noise?

I think the ES model is the later one, and that the differences are on the first page of the full PDF datasheets at the bottom of each inverter page. For example, with the ES it is possible to scheduler charging and discharging time slots-could be very useful :cool:

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...

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...

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...

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...

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!

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...
