i've pretty much given my opinion on that statement already... as to the proposal they made.. that was of marketing, creating demand and purchase numbers only, as i understood

deye = sol-ark = sunsynk

Again LVTOPSUN is a rebadger , not a manufactorer. As I said "it looks like" , I can tell you for a fact that it is no deye

you'll be fine pulling the info from every battery, with the exception of the master battery.. Once you set that as a CANBUS master, it wont respond to RS485 request anymore.. For my setup this isnt an issue, as i have a pretty big stack... simulation your setup , you would see something like...

You can use the up of the sol-ark 8k, even the same model number

I believe you can only change the V3 setting through the windows software and a rs485 connection. The bluetooth i think is monitoring only

Looks like this is a rebadged signeer inverter https://www.manualslib.com/manual/2507349/Sigineer-Power-M3048bp.html

LVtopsun rebadge multiple inverters from different OEM's ( just like EG4), so it is quite reasonable to think you may have a different inverter.. Deye doesnt make a 3KW model

If this is your reasoning, use a 400a t-class fuse ( like you already should be using :) )

Looked at Abb... For a slightly comparable mccb to the tomzn , I would need to spend over 300 euro, the noark's are even more expensive here

You need to use the proper app for your BMS.. V2 and V3 use w different app, both can be downloaded directly from the seplos site , after registration

400a is absolutely nuts for this inverter.. 200a at 51,2 nominal voltage is 10240 watts.. Your inverter will be overloaded long before that For my sunsynk 12k's I use a 250a tomzn.. Have tested that it does what it should do , and it is huge , heavy and spring loaded bidirectional Connected...

Why are you selling if I may ask ? Seems like a serious system that would serve a family well

Seems your shop vac might have a very high startup load.. Consider a smart start for it

We have, they have dropped 50% over a year and a half

Looks like the default settings, with changed ov protection ( which is charge voltage), like looks fine to me

to add... there was a time where Deye was selling their split-phase inverter directly in the USA, that stopped about 3 years ago.. There are a few that still have the original 8 KW Deye split Phase inverter ( i think @Lt.Dan and @RayfromTX i know for sure, you can see them at his YT channel...

not quite.... Wrote a whole story here years ago.... short take away story is : Keith started a company and engineered the first true hybrid long ago that produced the GTIL sun 1KW and GTIL sun 2 KW in order to grow the business he sold that company and tech to a Aircon factory of epic...

unless your EBC-A40L is broken ( which it doesnt look like ) , it is either your method, or the cells... could be cycled before you got them could need a little "pep up" fortunatly it is quite easy to create a test plan with the EBL software to repeat a test 2 -3 times

Not familiar with solax

Every inverter has its own implementation of what protocol.. rs485 , like serial is just the medium on which that protocol travrls

https://www.waveshare.com/rs485-to-wifi-eth.htm But as zanydroid already said , you'll need the proper protocol and "translator" for your specific inverter

Ok, so the problem is with you sol-ark setup in regards to solar sell.. Can you verify that is disabled ? Furthermore you can set the trickle higher, to ensure that the peeks will not be offloaded.. A warning though, a hybrid inverter will take and give a bit from the grid when connected.. It...

Again, if connected to the sol-ark, it should be exporting.. It is exporting to the sol-ark, not the grid.. The sol-ark "emulates" the grid The sol-ark then determines if the export goes to the batteries, the loads or the grid ( if setup that way).. The Enphase doesn't know the sol-ark is the...

Don't use Enphases zero export feature at all, as it doesn't make sense.

The zero export is handled by your sol-ark ( if connected to you smart/gen/aux ) port. The sol-ark will tell you Enphase micron's to shutdown by frequency shifting Connecting them this way will also ensure the still produce even if your grid is down Are your Enphases connected that way ?

Probably better.. They sat for quite a long time, and while in general lifepo4 doesn't have a memory, they may need a warm after sitting for such a long time

If that is the case, I would cycle test them at least 3-4 times from 3.65 down to 2.5 and back before comming to conclusions. What tester did you use ?

Lol..does mean sol-ark must have a HUGE overhead :)

Maybe this treat will get you the answers on not letting your LA go to waste : https://diysolarforum.com/threads/testing-lead-and-lithium-lfp-battery-banks-in-parallel.31202/page-3#post-1065569

Well. About 2100-2800 euro ( 2500-3200 USD) for the 12k 3 phase ( comparable to the 15k sol-ark) Sorry know that hurts

They aren't paralleled

When paralleling the inverters do not sync to the grid, only the master does and passes that information on to the slave.. The do however both sync to eachother using the common battery. Guess what happens if that fails 😔 This video is about single phase inverters, but using 3 phase inverters...

I'd go for a 3rd deye

No it is not, will cause damage But the exact answer.. Common battery, or don't parallel
