Thanks for the reply I did search the forum and found several threads with similar issues but not the same. Firmware update is a good idea, I'll give that a try. Thanks for the reply.

I have 2 SPF 3000 48V in parallel off-grid. They have been in service for about 4 months. I have them connected to a 280a 48v battery. Everything works perfectly, on a normal day, battery will charge to 100% around noon and any loads are covered by solar until dark and then runs off battery...

Update: Error in my logic. The value of 4 is actually bit 2 high.

I have an EPEver 6415AN. I'm reading and parsing the modbus output. The status register, 3201. according to my specification is D3-2: Charging status. 00 No charging,01 Float,02 Boost, 03 Equalization. but I'm getting 04. My specification is V2.3 2015. Does anyone have a link to a newer...

I have this Renogy 3000W Inverter Charger. https://www.amazon.com/gp/product/B07PNGVMZK/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 The Inverter has an RS485 port on it. Has anyone successfully connected to it in any way? Thanks.

I have some JBD bms's that I wanted to use esp-link on. I purchased several esp-01s modules. Doesn't matter what version of esp-link I try to program on the devices, they all reset after starting the dhcp server. Using the arduino IDE, any sketch I've tried works, wifi or not. I've...

Currently I have 2 banks of 4 280a cells. One is using a 100a Daly bms, and the second is using a 100a JBD. With 4 panels, I was able to work a small building project for almost 2 weeks with no gas generator backup. This unit had little to no problem putting out 200a however the inverter can...

That is my guess as well. However in my case, all banks are balanced, equal charged, fused and the max combined charge current won't exceed 150A. Also, a possible peek discharge of 400A divided over 2 to 3 banks would be a very rare occurrence.

That's good to hear. I do intend to at least try them in parallel. Unfortunately, they are all on a boat in San Francisco waiting to get unloaded. Won't see them till sometime next year:( Thanks for the input.

The manufacturer rep said only the JBD 50a to 100a BMS's worked in series or parallel. Looks like I'll be reselling 3 200a BMS's. Eventually, I will be rebuilding to 24v or 48v where this won't be a problem, however, that requires replacing my $1000 inverter. Maybe next year.

Hi, My goal currently is to have 300A to 400A to power a Renogy 12V 3000 to 6000W inverter. What I have now is a 100A JBD on 4 280A cells and a 100A Daly on another set of 280A cells. I used the current setup for about a week and it worked fine up to about 2000W. I have ordered 2 more sets of...
