I see some of my batteries not easy to charge over 3.35 or so I guess the new settings on 3.30 as starting level was better but maybe 3.35 will be better from what i see from my batteries. Pink

One more day with charging. My growatt and JK BMS show batteries full just before lunchtime. This 2 days i wake up to around 50-60 A left battery capacity. It seems that some batteries not easy to get over 3.35v but im not sure if thats even needed? After some balancing it look like 3.3x v per cell. 277 amp. 99% capacity is the standard i can expect. When balancing over3.3 look like its 80% done by de-charge who is higher and very less added to lowest batteries. So 55.x will end up with 53.x when finish balancing. Pink

You correct. My mistake. Pink

Today fist full day with all set up as it should be to work normally. Total generated today is 24 kvh. Its funny how carefully Im with the usage of electric now when its "free" Pink

Now i understand why active balancing only at the end of the charge is discussed. I had set my JK BMS to start balance from dc 3.45v as in this video but ended up with deviation of dc 0.2xx v who took much time to get balanced back and I feel it messed up the charge process and I also guess its ineffective. Now i have change my settings and try balance from dc 3.3v tomorrow. Lets hope thats a better and smoother way of charge. Pink

Good performance Crossy, almost 1000kvh Pink

Great numbers !!! Pink

So i have adjusted the charge voltage some up. Actual charge voltage is some lower than what in the settings on the inverter. Currently charge at 50A or so now who is much better. Pink

I must admit Im curious to see if if will produce around what i expected and calculated it to do. Things seems to run a bit low for now.. I get less than 10A charge currently Pink

So i was sure to wake up early today to get some charge before grid was taken down ( will be down whole day) So i started up charge from solar as soon there was some sign of daylights but that was very optimistic from a solar beginner. I had to wait an hour or some before see and sign on charge from the solar. Now grid is down and i have got up my wifi monitoring on the master inverter. I have not figured out yet if it show data from master only or master and slave inverter together. Pink

Yes, It also a plus to have planed and build it so it can be managed and fixed as much as possible by myself. Pink

All was up and running at lunchtime but because of the weather and my batteries needed to be charged I turned off AC Out on the inverters. I only tested 15 minutes or so today offline from grid. Pink

I was seduced many times when planing and buying with some cheaper options but I tried to choose good value (Good quality at good price) With the hope that It will last for many years but time will show. I tried to plan the setup to have some extra margins for the capacity on for example inverter. But time will show.. I spent more or less exact 300k for all. Electric bill lately been around B 4k (+/- 500) so maybe 6-7 years needed for ROI. Pink

I got the news early this morning. Then i decided To get this finish and up as soon as possible, so I skipped breakfast and started right away.???? Pink

Im currently charge at around 20Amp per battery from the "sun" Pink

I dont really have sun today and tomorrow they told grid will be down 10-12 hour or so from early morning so I just grab what i can get now to charge up my batteries for tomorrow so i have to use grid for home today. Very happy to see it working..next i will get up the monitoring software on wifi so i got some more feeling on whats going on. Pink

Just got all up and running with the 2 growatts in parallel, so right now im on solar power !!! Pink

JK BMS default does not charge or take load so it had to be setup. the i got the expected voltage. pink

Both bms are up and show normal voltage but on inverter battery poles i get 155mv. Pink

Needed some days waiting for some small parts.. but now battery 1 is up with JK BMS. Still need to do the settings, this is default settings. Pink

Very good point. Pink

Yes i remember that from some earlier post..very confusing but very correct. Pink

Im setting up a routine for startup and closing down the whole setup. If any have some corrections or improvements pls let me know: START UP 1 Check BMS Its Turned ON - Precharge 10 sec - Open Battery Breakers 2 Open breakers For Solar 3 Open Inverter ONE - Open Inverter TWO CLOSE DOWN 1 Close Inverter TWO - Close Inverter ONE 2 Close Breakers For Solar 3 Close Battery Breakers Pink

Today I got the ATS up and connected to grid and Inverters so one step closer..

Yes all will be tested first. Pink
