I'll will send you that tomorrow. PM me

But sure you understand the rules and update you post accordingly ;-)

Hello Alvin welcome, be sure to comply with the "New vendor rule" if you don"t want to be kick out ;-) . https://diysolarforum.com/threads/update-corporate-corner-group-buy-section-is-now-removed-and-new-rules-for-vendors.36121/

you may need to contact the author if you are not familiar with building and flashing on STM32 platform.

External switch OFF When at the standby status, the BMS can be powered on/off through external switches. basically you can have an external switch ON/OFF .

many people are doing the same mistake. CANBUS is a interface, not a protocol. jkmbs has a specific CAN protocol not supported by sunsynk. So basically they won't communicate. You will need to design a JKBMS-CAN to PYLON-CAN protocol translator, or a JKBMS-RS485 to PYLON-CAN All JKBMS...

- you have to triple check your balance cable. (have someone else to check it also) - did you have any picture - did you check cells level with the pc sofware and usb/rs485 interface - when did you buy this BMS ? - did you report to seplos for assistance.

M5

it can be set up, up to 5 sec

seplos BMS doen't support both CAN & RS485 only one of them depending of which version you order. don't try to upload RS485 firmware on a CAN version (or the other way) you going to brick the BMS.

hahahaha

To my friend I say, stay away from voltronic base inverter. you can't trust a product coming with 1 yr warranty. if you do your research you will find out, most of their new hight power PV inverter has bug. mpp didn't design the inverter. buy an inverter with at least 5 yr warranty, from a...

you can buy them in EU for a good price at solarpower24.

I would never replace it with a voltronic base inverter, a DEYE hybride sound a lot more appropriate. ;-)

Yep All answers are in the thread. To make a long story short, Amy was supposed to make the box, after some delay, she said "why not just ask seplos to design the box". Then I asked Amy to send the cells to seplos, and I started the thread. I paid the design fee. I was pretty sure this box...

Ok I see, makes sense.

I always rate my busbar at least x2 my charge/discharge inverter capacity. if you expect all 4 inverter to charge/discharge at max rate at the same time (4x120=480A=> x2 = 940A) in this case I would use 1000A busbar. But to be honest I would rather use 2 x DEYE 12-16kW inverter and...

Do not hesitate to give us feedback on your purchase and test experience. I can tell you that it's complicated to get your money back if you don't have your cells, even if you pay with paypal.

BTW A new box format for 185Ah blade style cell is coming. The thing is EVE,CATL, and CALB probably don't have this type of cell on the market. :-( .

The packaging really needs improvement it's too weak for a box of this size and weight, I'm sure you've reported to them with a picture, I'll do my best for them to change the packaging. For those who need the connector, they are usually very expensive (16 - 20$ each), I may ask them to add it...

there is no free solar energy.

You can start with easyEDA , it available online and offline. Simple to use and come with a very very large components library. With no experience it takes me 1 day to be able to do a 4 layers board. I did plan to switch to kicad but it so practical to have easyEDA connected lcsc catalog.

You need to call the support, to know your best option. You probably need to build a custome wire.

Price is fair bcoz you have everything except the cell. 1500$ was air freight.

Sunsynk is a deye rebadge inverter. You can see on seplos yt channel they build a large solar installation with deye inverter and battery with seplos canbus bms. You have to select pylontech. Unless sunsynk specifically remove pylon support from their inverter it should work.

Choose CAN

Do you have a written documents specifying 5 year warranty ?

It doesn't matter, forget about it

Epever 5415 can handle 2500w at 48v it cost 195 € , then you can get a 2000w or 3000w at 48v pure sin inverter from epever for 285 € to 335 €. You may also consider a voltronic base all in one low voltage pv inverter like mppsolar for example (cost less than separate scc and inverter).

You need to defined your requirements first, we don't know what you are trying to achieve. Did you already have the 2000w 24 panels? If yes you need to decide if you going to use 12v or 24v or 48v battery, depending of your choice scc can be selected.

For example ou can get epever triron 4215 scc from solarv directly or through amazon at a better price than from AliExpress

Try at least to buy something with a name on it. Even chinese brand like Epever, esmart, srne.

I can't trust an inverter who can't talk with pylon ;-)

that's sad, bcoz they have some very products with nice prices
