I am also in same boat like you, i would think that better solution is to use Chargeverter to charge battery to limit bad quality of power from generator, how did you manage to solve it btw?
Starting to build offgrid system, already kicking and firing questions in forums :)
good to have such place, hello everyone.
Fully build up a campervan offgrid system fully autonomical one, controled from computer all the way.
1kW of panels, 300Ah Lifepo4 12v battery bank, based on raspberry...
Well good you write it, it can be done. If no power goes from generator it can try to start again, and such loop can be done 3times. If 3 times does not switch it on. System will send message that generator does not have gas or something else. Many things can be programmed with python on...
Chargers Itself it would be same as you state, but importance is there that Inverter has it on PV, and not bypassing Inverter and connected to battery. So statistics are without any false reading. It is always better to pass thru Inverter everything since it is heart of the system, not bypass...
Okay, so i have been diging that JKBms and Deye will not work by coms, i cant connect them together with coms as jkbms is still in beta for deye inverter. So in this situation how do i not messup inverter readings from battery when chargeverter works ?.
Cv2 is generator switching on and off ...
Well if i have BMS connected to Inverter by CAN, it reads volts from battery, it have all readings from BMS and provide charging acordingly to BMS status. If i put chargeverter after BMS - does that produce any implications for inverter communication with bms or for inverter itself, additional...
Indeed. And now i see that it will be problematic to connect jkbms to deye so i can setup inverter only to get voltages from battery and in this situation, „false readings” will occurr for inverter if chargeverter will be on.
How to solve it ?
I have Deye and Chargeverter. Inverter is connected to batteries with JKBms without com communications, Inverter is setup to read voltages from battery (coms jkbms in early stage has many bugs with deye)
So How do i charge batteries properly with chargeverter so that deye will get proper...
Is it possible to connect both with coms without any danger ?, heard from guy that was working with unofficial bridge that batteries was drained to 0% because of bugs in JKBms firmware. Has anyone working solution and deye reads all data correcly in both ways ?
it seems that isc for g12 is to high for Deye.
Isc is max 17A and working current till 13A. Panels has nearly 19A Isc it will be bad.
Any other bifacial double glass 600+ watt recomendations ?
Is there anyone could help me with the numbers ?, i am bit in the fog, right before i choose solar panels.
Actual system specs:
Eve 316ah MB31 3,2v 16cells
Deye Inverter SUN-12K-SG04LP3-EU
Chargeverter 5kw (generator behind it)
Thank you for answering me. It is more clear now for me. So basicaly it has to be properly setup on chargeverter and inverter. There is no implications for Inverter to receive charging power from chargeverter and battery (bms will pass thru what batteries need, and inverter will do the same)...
So i have been digging around how to hookup my system together, seems that using Gasoline / LPG Generators that does not have inverters inside (cheap one) hooked up to Deye Inverters is really bad idea because of bad quality of power they produce.
Since i am in difficult geographical position...
I am in same situation, but i have generator 1phase and deye 3 phase, i would prefer to use generator for charging batteries not input it to inverter, yes ofcourse if generator has inverter inside, then okay, but otherwise - i am still thinking how to do it, chargerverter is a way ?
Indeed chargeverter is good solution i am also in different boat, my generator is 1phase and deye inverter i have is 3 phase. I wonder if chargeverter can be setup to charge Lifepo4 48v 314ah correcly without communication with jkBMS i have, is setting gargeverter manually sufficient in terms...
They dont say that CV will not work. They just say that Having deye connected when CV is charging is a bad idea?, but why they say that i dont know.
I wonder how to make Deye not charging batteries when CV is charging. It would eliminate potential problems?.
What kind of Solar panels choose for 12kW Deye Inverter?
I would need about 5kW of power for now. I will expand system in next year.
I was thinking about Bifacial with double glass panels
Such as, 650W or 700W Double Glass Bifacial HJT
Panels will be on tracker in mountains. They will not be on...
How about
Deye 12kW inverter charging batteries thru
jKBMS and Chargeverter charging thru jKBMS also, jKBMS communicating only with Deye. Chargeverter setup manually. Is this scenario possible
?, will jKBMS limit charging overload if it will happend ?, is it possible to charge with two sources...
Inverter terminals for Bat+- are same as BMS terminals. Just couple cm in diff direction. I am saying about something different if you carefully read my post.
I know that it is not main subject but anyone sucessfully fully connected JKBms to deye ?
And sec question, will deye turn on only from batteries ?, np pv and grid?
Right, sorry for being so borring for you, mate. I am just trying to get all kind of viewpoints and solutions and then choose the right one for me. I am at begining with that adventure i dont want to break anything.
ps. I dont want to overcharge also anything.
So Inverter with BMS is the way to go, and CV without communication, just set it manually to charge at certian levels ect. Right ?
Your second paragraph, can you explain in more detail how you will manage to do it ? And more detail ?. You will connect Grid to generator socket in inverter and...
Anyone has tested chargeverter with system that there is different inverter than from EG4 company ?, i am thinking to uplink chargeverter to system that has deye connected all the time
So i have Deye 13kw, eve 16s 48v 314ah and chargeverter, connected to jkbms, so from posts above there is no problem to charge batteries from inverter with 0.25c and chargeverter with 0.25c, and inverter set to discarge with 0.5c - batteries specs show that 0.5c charge and discharge is possible...
Thanks for presenting me your logic
The problem is that, i have deye inverter in the system, and deye support are telling me that connecting charger to batteries in system where their inverter is connected is no way to go as i am putting something behind inverter and as they say things should...
Manual choke is present but starting from key is there. This key is like in car so i could start it by uplinking to wires behind key. But i would need to make some mechanism to move choke lever?…
Well i have generator without Inverter so it has poor AC quality. As many of you perheaps, so i dont want to connect it to Inverter as it could do harm to it.
I was thinking about chargeverter but since connecting chargeverter could make problems in terms of false battery reading in inverter...
Yes i am planing to wire that myself but for sure i will use all way remote support that i can get.
So you are saying that 10 panels of G12 700w will be better in terms of starting MPPT?, how about winter ?, if there is not much sun, how i can calculate if mppt will start when there is less sun...
I am collecting my offgrid solar system, i need to understand and connect in safe way panels in two strings to my Deye 10kW, can anyone help me in understanding possible problems, things that panels need to have so whole will be safe and efficient ?
Like i said, there are couple viewpoints and much info that i already got from my questions, each answer got more cents to my question and now i have better understanding for system
How it works, and this post gave me and others more info for gen topic. For that i am grateful, for your help...
If Inverter is connected to Battery BMS it will see battery exact voltages, SOC and other readings which bms gives. So if CV is charging batteries, inverter could have inconclusive readings because comms will show different readings than readings from battery cable where CV is connected.
Or...
There is another solution, how about buying microinverter 1phase like easun 6kw and link genny to ac in, batt out to main system. Then we got additional pv input and we are passing all that noisy ac thru other inverter
There is another solution, how about buying microinverter 1phase like easun 6kw and link genny to ac in, batt out to main system. Then we got additional pv input and we are passing all that noisy ac thru other inverter
I have my Deye 12kw 3phase inverter, it has possibility to connect another 1phase inverter to pass AC to it.
Why ?, i will want to connect to 1phase inverter to my 1 phase generator. Or i can connect second battery bank to it, that way i am passing this two or one thru Deye with no-void of...
I had to change my panels to 615w model, can you tell me if 7pcs will be okay for now ?, i will try to go with more but there is no more in stock.
Panels i have chosen are G12 615w
There is spec...
Folks do you have idea what solution inverter is less sensitive for connecting low budget genny 1F to AC in to charge batteries only?
This one ?
