Deye recently updated the app and I can no longer do a read using remote control. Anybody know the solution for this?

I have a Deye 8K (basically a Sol-Ark) along with 10 Enphase micros connected directly to the same sub-panel box with line-taps to meter line input. It works perfectly fine with excess power in any direction. If there is excess Enphase that Deye doesn't need, it will push into the grid. I ran...

59.3 grid low Voltage out 120/240 I did another test today and set TOU at 57v min,l and it worked, so that wasn't the problem. At one point yesterday, I fat fingered 560v instead of 56v. The UI gave me an error and I thought I fixed it, but perhaps that caused a DC bus shutdown, but reboots...

I was trying for 3.56v per cell for a top balance, so you are correct I guess it wasn't equalization. I was using the individual cell resister and charge approach to get them close quickly. Seemed to actually work since I think they were somewhat close from factory.

Ok, I had battery set to a high voltage in TOU menu to force an equalization. Once I dropped it back down again, it started pulling both battery power and solar power. Perhaps having a really high voltage value in TOU menu caused this issue. I may experiment more later, but its working for now.

You can see it was working fine, then all of a sudden it dropped to near zero. I also tried rebooting the tigos but didn't help.

Yes batteries are charged. But I've run this inverter without any batteries before as well. Regardless of batteries, wouldn't it pull power and sell excess? I have sell enabled. The charge % was off earlier, which seems odd because I thought it used volts to estimate rather than amp...

I'm using voltage mode on the batteries right now. EG4-LL on the two existing and the new is a build with EVE 280ah and JBD bms. The batteries seem to be working fine, I just can't figure out why the MPPT isn't pulling power from the panels. Grid and load all appears fine as well. It should...

I was working on a new battery pack today and messing with charge voltages to attempt top charge with close to balanced batteries. At one point I switched back to old bank to work on new one in isolation. Awhile later, I see switched back. I did this by throwing breaker on each bank. The...

My batteries are brand new and over first week of operation the soc/voltage is changing daily. It's now to 51V=2% it started around 49V=6% I'm not hitting 100% so maybe it's learning incorrectly.

This looks like the hub. https://signaturesolar.com/EG4-LiFePOWER4-Communications-Hub

It's a quote from the eve280k spec posted above. I guess the assumption of 50kn/m2 but no other denominator makes sense.

That spec indicates... "It can be seen from the above table, that the compression force of the battery cannot exceed 50 kN, otherwise the battery may be damaged." A 50kN force is equal to just 7.25PSI - The target PSI I've read on these batteries is 12PSI-15PSI?

Your example here is for a SINGLE CELL SAMPLE.. that's why the price is so high. If you want regular price... order a minimum quantity of 4. Note the "Samples" in the upper left corner and MOQ of 1.
