Don't call your friends when you install the big nkon box 🤣
Luckily my battery is in the garage so an easy roll in from pallet drop.
think thats the best approach
I'm thinking of getting the 16kwh nkon box, if someone wanted to go halves on delivery?

Seems like a good deal, not sure how it’s tax free from Ukraine!
your in the non eu site, and its not from ukraine, its tax free to ukraine ~Link for EU

Are batteries from EU countries tax free? Is the price at checkout what you pay?
Example, this dyness one from Netherlands.

If on the EU site, It's including vat., there will be no charges once its arrives. Benefits of being in the EU
Thanks.
Some good value on batteries these days.
Do you know if the one I linked is plug and play?
When should SOH start dropping on a new Fogstar/Seplos BMS 16kWh battery connected to a Solis S5 inverter , Its working well but the battery is less than 1 month old and done 26 cycles but SOH has dropped to 99.8%.. Is this expected or is there something wrong ? Thanks.
Yeah, it should be.
Id say expected, the SOH is just a cycle counter, nothing anything more than that.
I wouldn't worry about it.
Hi, I’m looking to add a Dyness G2 10kw battery to an existing 3.6kw hybrid inverter. I had 2 2.4kw Pylontech batteries that have stopped working in the last year. I don’t have room for the Dyness where the Pylontech batteries were so I’m going to put it on adjacent wall that would mean approximately 5m of cables from inverter to Dyness. There’s a breaker with 80a fuses that were feeding the Pylontech batteries, would this be sufficient for the Dyness battery and what size cables would I need. Thanks.
Would it not make more sense to go with a 16kWh Seplos type ?
Use 35mm² cables.
80A @ 52v is only 4kW
80 amp is fine for your inverter.
Would agree with the 35 mm2 cable because of the long run
I’m tight for space, the dyness can go up on a wall out of the way. If I decide to go with another dyness down the road and upgrade my inverter to 5/6 kw, will 35mm still be ok?
I Want to get my father in law a 15kw battery and then he can charge on the cheap night rate and pay very little for his electricity throughout the year. He has no solar setup so far, so he'd need an inverter and 15kw of batteries. My question what is the cheapest roughly he could get that for? Not a DIY job, but an inverter, 15 or so kw of batteries, that will load at 5kw per hour so he can fill them during the night on the cheap rate and all to be installed by a professional installer. Are we talking , it's possible for 2-3k after grant or does grant not apply?
Grant does not apply as no solar panels in your scenario
Thinking about a battery to avail of night rates but looking at my usage, January was the heaviest month using on average 43kWh per day. 31kWh was at day/peak rate. Am I correct in thinking I'd need a battery set up to at least store that amount to cover me every day?
Next question, what's the cheapest way to do that, possibly DIY.
It's all down to the size of your night window, and your mic.
You could get 2 x Seplos type packs, and then parallel a rectifier to get the charging up beyond the inverters 5kW limit
Not sure about this supplier but I toke a chance and purchased from them they said 10days from Poland
Pre-assembled 16kWh 51.2V 314AH LiFePO4 Solar Syestem Battery Pack ,Bu – Deligreencs
cheers just have the Energia EV one at the moment, 11pm to 8am.
You will need the electrician to install the inverter and submit the NC6 because it is capable of exporting to the grid. The cheap 4 hour window will let you fill one 16kWh battery, but adding a 3kW rectifier will let you charge at 8kW, so enough to fill two batteries.
You can pick up 5kW Solis inverters on adverts and DD for around €500-€600 new. Batteries will be a bit over €2k each if buying pre-built.
How much energy is needed?
Hi, I have a house in Dublin that has total of approx 26000Kwh batteries (2 x 5K WECO's and 1 x 16K Seplos), charging during the Energia window 2-6 with 5K Solis and Huawei R4850 rectifier (I only run this at 40a as at 50a the fan on it makes it sound supersonic) the most I can get into the 3 batteries is approx 23KwH thats if the WECO's hit 6% soc and the Seplos gets to 12% at best (I run the Solis as WECO battery and hence the inverter derates to the WECO discharge current which makes it hard to get the Seplos much below the 10%)
Ghost do you have stats to show the 32Kwh charge?
Hi, I have a Solis Hybrid inverter and a Weco 5kw battery, I wanted to add another 5kw to the system but I am not sure if the inverter will accept two different batteries?
This is the Dyness battery I was considering https://www.nkon.nl/en/dyness-dl5-0c.html?_gl=11wgi061_upMQ.._gs*MQ..&gclid=CjwKCAiAw9vIBhBBEiwAraSATjRCM48fUFN5b7R9i1RFJZhCK68F1RD9OejhakcRpyQ0DuPYUjFsFRoCZLsQAvD_BwE&gbraid=0AAAAAD1QO9hf5kOEj4rfkOUh1rPE7OIV8
What type of weco is it? You'd have to parallel them and just let one of them link with the inverter and the other run without control. I had this kind of set up for a while with weco batteries paralleled with a DIY battery running on a JKBMS and it worked ok. It wasn't optimal though as the inverter was blind to the weco batteries and so would often stop discharging based on the JKBMS when there was some juice left in the weco, so wasn't getting full capacity from the weco most of the time.
oh, thats interesting. All I know is its a Weco 5.3KWH.
Mine were the Weco 4Klt but I presume it would work the same. I vaguely remember some advice I think I got on here that it's best to have the larger battery communicating with the inverter. It won't be perfect but should still give you most of the available storage in the unlinked one. I think my Weco used to discharge to just below 20% before the other battery would be reading 10% and the inverter would stop discharging. I wanted to be able to discharge to 10% so didn't lose much capacity. I also probably could have gotten a bit more out of it by playing around with the inverter settings or the JKBMS settings but ended up upgrading to a larger DIY set up anyway.
Inverters will happily work with zero communication, by setting the battery up like a leads id, and allowing the inverter to guestimate the SOC%.
The most important thing is to determine the composition of the existing battery, since it could be 15s or 16s. Checking the voltage when fully charged will confirm it
Really curious about how this goes.
I have confirmed that my semi d party wall can easily take 120-150 kgs, now that we are into winter the existing 5kWh battery is flat by early afternoon. I think it's time to get a 16 kWh installed. Although most models / cases don't mention anything about wall mounts etc, most seems to be designed to stand up straight or on coasters.
I meant to quote this message in my last comment.
Deligreen also have this Seplos DIY kit offer… that appeals to me as I think it would be easier to build in the attic than trying bring 130 kg up the stairs and attic ladder….. Can someone more knowledgible please review and comment on this listing - Does EVE vs CATL matter?
