Any idea of the average watt usage of the 9000 BTU air con? Pink

Currently I measure 32 degree air temperature.. Goal is hat the machinery and circuits are cool enough. I guess temp will raise more with more routers pc equipment etc in the room. Pink

My 5m2 technical room have always been a cold room because no windows and how its built. After get 2 x Growatt inverters in there its getting quite hot in there so I consider to find a way to cool the room down in a way that make sense. Maybe some cooler direct from a dedicated solar panel? Pink

80 $au is quite allot of money to just be connected! Pink

Just keep grid as a backup option on a ATS. Pink

Good Point! Pink

I was surprised today to see that i got quite good level of solar power even in a light raining, cloudy day. At 14.15 my batteries was recharged, so Im exited how long i can keep running without my ATS kicking inn. Pink Pink

Get AC's with inverter, used less less power. Pink

Ok thanks for that info. My garage have grid supply so i just connect it there then to avoid any issues. Pink

Is there any reason to not run power greedy applications like a rice machine and power tools on solar power from hybrid inverter? Im getting 7k watt or so middle of day and our rice machine uses 3kw or so (4hp)? Pink

The EV will do the magic for your ROI and must be counted !!! Im "semi offgrid" I dont have any grid supply to my inverters but i do have a ATS with grid power so im very exited to see hoe much i can live without it kicking in with any grid power. I guess 2-3 rainy days... Pink

Yes you are correct in morning i use to see 55-65% remaining capacity. Last day i see 5W at 05.55. 08.xx I use to have more solar power than usage so charge start, then finish around lunchtime. I have set charge limit to 50A. Pink

I have very few days to refer too but charge current most of the time 20-30A. Charge time have been 4-6 hours. With latest settings there is very little or no balancing needed in the end today. Pink

I can only speak from my experience this days. With voltage 56v and before that 57v some of the cells picked up much faster on the higher voltage and then BMS got quite busy to try balance out that most by discharging. Pink

Done some small adjustments on JKBMS settings and reduced Growatt charge voltage to 55v and now it charge in a better way and very less volt difference between the cells. Pink

Thanks for the info, yes im on it researching. Pink

Ok thats quite good. I see many talks about cents per day per unit on mining now. What you mine? Do you have some links and details to share? Feel free to share here or PM me with any info you have to share. Pink

Do you have a link to the ice make machine? Pink

Im researching same now... You have some details to share? Pink

Good idea. How much the temperature in your freezer down just before its power back up? Pink

Anyone thought of any usage of the excess solar energy some of us have after batteries are full and its still much energy who could be used for something usefully? Pink

Thanks for that info.. I got same 100% SOC on 3.35 so all is fine then. I also want to be moderate on charge and battery voltage so then all fine. Pink

I have watched quite a few and I think the setup is ok. The question is if its normal or not for the batteries to struggle to get over 3.35v? Capacity wise it seems ok.. Pink

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
