Thank you for the detailed comment. For now I will only have 2 packs of 16s but will probably expand to 3 later on this year. As I understand, method 3 is the best but might not be worth it. My two packs will be max 150a charge/discharge each and if I add a third then 100a each. Is this a good...

I have a pack of 32 eve cells 305ah in a 2p16s configuration and I'll be splitting them into 2 x 16s packs with their own box/bms. Wondering which of these two methods is best for connecting them together. (I do have a 200a fused disconnect before the inverter connection) 1. Use a solid busbar...

Yes that could work, it should have both can and rs485 pins on the same port

Ah, I don't think that exists on the 16kw, at least not in the manual: Think I need a splitter for the top left port to put both solar assistant and the meter on the same port

Did you say you connected HA to one of the parallel ports? I won't be using them anyway so if that works to connect solar assistant then great

I was talking about AC grid charging which tops out at 8kw (140a-ish) since that is the limit on the AC side. Will need to wait for a proper sunny day so I can see if I can get closer to the 190a from pv but usually the battery is already past 80% in the morning so no way it could push that much...

Yeah using a 200a jkbms and I can get it to 140a max on the 8kw sunsynk and only have a 3 hour night window to charge 30kwh of batteries which is not possible. I usually import and export as much as possible, since the import in the 3 hours is 5x less than I get paid for export and then export...

Are you doing any grid charging of your batteries? And are you seeing anywhere near the stated 12000w power coming in?

Thanks. 60a on both grid ac and backup load?

@houseofancients what size breakers/rcbos are you using for the 12kw version?

I have messaged the SA guys and they told me that sometimes on some ports and some firmware, it is not possible to send change commands, read but not write. My Sunsynk has 6 ports, making it easy to connect a meter, battery CAN, solar asisstant, and the wifi dongle all working together. The Deye...

After a quick search on this forum for SUN-16K-SG01LP1-EU the Deye 16kw single phase hybrid inverter, didn't return much I suppose it is worth asking on a separate thread. Thinking about upgrading to one of these and had some questions: In the manual it says to add 200a AC breakers on both the...

Anyone else getting 502 errors today? Web portal also throwing error on desktop but the mobile app is updating correctly.

I asked them the same thing, if I can connect to the bms via the PC cable then it should work on SA as well, I gave them access to my instance to test. But you can more or less control it remotely just fine via home assistant and esphome, just create a new device (needs bluetooth) with this...

Never installed the seplos, at the time I had a Solis inverter and nothing but trouble with that. Also it doesn't have a balancer built in (I think newer revisions might have)

Already set up, the bms is connected via CAN to the inverter and they talk ok but it looks like the inverter does its own thing first. Example, the inverter empty battery was set to 43v by default, and even though the bms empty battery is set at 42.2v, the inverter cut the discharge at 43v. So I...

I have a sunsynk 8.8kw hybrid inverter and a DIY battery bank of 32 cells, Envision ESS 72173207 305Ah, 2p16s, connected to a JKBMS JK-PB2A16S-20P I have these values set at the inverter and was wondering if they are correct: The BMS also has float mode enabled, so not sure if the BMS values...

I just picked up this BMS but cannot find any proper user guides/diagrams for it just yet, I suppose it is quite new. Will be building a 16s2p battery with it when the cells arrive. Just wondering on the wiring of the balance cables if there is a diagram for it to ensure I am connecting...

Yes that did the trick thanks

Sunsynk did some upgrades today and it looks like data is no longer coming from https://pv.inteless.com/api/v1/inverter/battery... Something with changing from Region1 to Region2 Anyone know what the new URLs might be?

The batteries are dyness and they all have their own BMS so all that should be controlled by the BMS. I also had the pins of the CT flipped so it was reading grid usage as export, flipped it around and then the batteries started to work. I have this very annoying constant grid trickle of 100w...

I just installed an 8kwh hybrid sunsynk and I am struggling to make it discharge from the batteries. My use case is as follows: 08:00 - 23:15 I want to charge the batteries with excess solar after house load and drain the batteries to the house if the PV is less than the load. 23:15 - 08:00 I...

Anyone ever created a 3d printed case for the BMS? Pls share the stl if you did :)

I understand the Pylontech US3000C is not a DIY battery but perhaps someone here can help me with determining the maximum power a Solis 6kw hybrid inverter can draw from two of these batteries. The inverter has a max charge/discharge of 5000w. The battery has a nominal discharge current of 37a...
