This thread: https://diysolarforum.com/threads/solar-assistant-power-backfeed-from-eg4.69755/ @solarhombre generously shared their M5stack setup for battery monitoring. I've purchased the components but haven't had time to set things up...I thought that was pretty cool. @timselectric mentioned...

I'm glad this was asked and explained because, as you probably guessed, it was mulling in my mind. :) I assume closed loop = all 4 inverters comm connected paralllel/current/etc and open loop = what I have.

Everything looks good, it seemed to have stopped. Maybe I was just being over sensitive since I just got everything up and running yesterday. The dim might be another issue I’ve had for a number of years now possibly related to an outside temperature swing. It started after I replaced a...

I’m getting something a little strange. Yesterday I got it all working as designed, but don’t have all my pv built yet so our loads drew more from the bank then what the harvest could supply so I switched the house back to grid overnight but kept everything else on the two invs (3&4) running...

Yeah, it’s a new area of this build I need to devote some time in learning. Many have built their own banks and bms and have that knowledge. Whereas I arrived later in the game and choose to go a little more turn key, but I lack in the battery/bms area. Yesterday, I got all 4 inverters going...

Thanks for your help.

So what does the equalization value you told me to set, do? Setting 31 default to 58.4v?

So bulk is setting 27, and equalize is setting 31 with default 58.4v. I’ll change both to 55.2. Confusing with setting 30 equalization to disable when we want to equalize with setting 31… unless they mean automatic equalization for setting 30.

Why would you stick with sbu if I have no utility connected? How to disable equalize…is that in bmstools on the battery? Nvm…found it setting 30 set to disable…got it….disable was default setting anyway.

Can you recommend a starting point for the settings for if I set them all to USE. I’m totally lost on that at the moment. Don’t want to damage anything. Trying to understand that manual is very challenging. This is why I thought it might be easier to go eg4/use have the bms do it for me and...

Ok thanks. Any difference which inv goes where regarding the phase? So it’s inv1&2 master and slave split phase and inv3&4 master and slave split phase. These two sets of inverters will not be comm connected together, so their phasing could be independent…not sure if that matters since we are...

I need to setup my system for USE battery mode instead of EG4 mode but I don’t know what settings to change and what the setting should be changed to. Can someone help? My setup is 4 inverters setup as two separate systems. Inv1&2 are split phase set to EG4 and USE for the master and slave...

Ok, so I got my bus bars, and they look legit. What I’m trying to determine now is the battery to inverter spacing on the bus bars. My setup is four inverters setup as two separate systems 120/240 split phase all connected to the same battery rack. I can’t get all inverters bus bar...

Did a continuity check, the neutral bars on both sides of the the shop subpanel are connected, I thought they were separate. I was thinking about the neutral return path for 120v a bit (trying not to overthink it). Regarding the combination of the two neutrals from inv1&2 into one #4 which...

I’ve been thinking about the lynx…just curious. In order to get the current thing right, the stagger deal, would you do like the rack bus bars are? Diagonal configuration? So battery cables at the ends, then for the pos, going from left to right if top view pov batt on left, inv1-2-3-4, then...
