Huh... Yes, that does not look like mine ? Mine has some Sungrow stickers stuck over some of the Chint ones... I'll try to take a picture when I can. When you say it came with it, you mean it came packaged in the same official box as the inverter, from Sungrow? Or, would it be possible that...

Just checking in - how has your battery project been going? ? Thankfully, my 51.2V pack has been doing pretty good the past few weeks.

So, I'm not sure how related the SH10RT and the SH5K-30 are, but for the SH5K-30, all meters need to be plugged into RS485 inputs dedicated for meters (A2 and B2) - so there's no iSolarCloud configuration needed. Plugging them in to any other RS485 input won't work for the SH5K-30, as far as I...

Okay, problem solved, finally. I got a Sungrow branded DTSU666 in the mail yesterday, and sure enough, it has proprietary settings ? It's communication settings are as follows: -9600 baud -None parity, 1 stop bit -Address 254 The only reason this is proprietary is that the original DTSU666 I...

Tiny update: I got a RS485/USB adapter, in order to confirm the communication settings for the S100 and DTSU666, both. The S100 does appear to be communicating as follows - - 9600 baud - None parity, 1 stop bit - Address 32 So with that, you'd think that the inverter should be able to pick up...

Yeah, so, for me, when I select "Other Battery," and then turn it on, after it goes through the Start-Up sequence, it does take a few minutes to fully utilize the battery. At first, it will only send a few amps to check if everything is okay, and then stop for a bit--and then send a few more...

Glad to hear there's someone else in the world with this inverter! Doesn't seem like there are many people on the forum with Sungrow stuff. I can confirm that the SH5K-30 can take batteries without CAN communication. Sungrow talks about this in there manuals in regards to lead acid packs, but...

Thanks again, you guys! I can confirm that it was a bad connection ?‍♂️ While the new terminal post was good and tight, in my concern that I might strip the threads again, I must've gone too gingerly on the nut clamping down the bus bar. When I took it off to investigate, the bottom was...

Super appreciate the reply! Good to know a recommended place to start investigating - and that the behavior might still be related to a bad connection (even if it's looking a bit fishy, in that regard). Yeah... definitely contemplating a BMS upgrade - lots of people complain that the Daly's...

Okay, so, search for "bad cell," or "bad connection" on here, on you get a flood of results ? It seems like most people wind up needing to get in there and start trying to fix stuff before they figure out what's wrong; but before I go ripping apart my pack and testing things, I wondered if...

Okay, the "Ct" and "Pt" settings were a bust... The Chint DTSU666 manual says they stand for "Current Transformer Ratio" and "Potential Transformer Ratio," and changing the settings seemed to just add a multiplier to the readings on the DTSU666 display, but didn't seem to effect the inverter at...

Okay, a tiny bit of progress: I found this other forum of people discussing connecting to their Sungrow inverters for data tracking purposes, and saw someone post about taking readings off an S100 meter. This is what they found: "Modbus Response (COM3) Address: 32 Function: 3 (0x03) – Read...

Hey all, It seems like the last step before I can really start using my solar battery is to get the inverter clued into what's happening with our power usage in the house, so it can do export control. Long story short, I'm having trouble getting the DTSU666 3-phase meter installed on our...

With that, now my cells are too far out of balance 'cause that one wasn't getting charged/discharged correctly, so now it's back to top balancing the whole pack... ?

I think I figured out what was going wrong with me. I had a balance lead that was connected just well enough that everything would look fine just sitting there--but once the inverter started charging/discharging, the connection would break down and look like the cell was going too low, and...
