Your video illustrates one of the main reasons I prefer systems built with redundant components. If you have two batteries (or inverters, or charge controllers), then it is so much easier to troubleshoot problems. The other benefit is that you can keep the system running with one component out of service. I also like how clearly you showed how it’s done. Keep going! I enjoy your channel very much.
Love those EEL battery cases, I have dealt with those folks when I purchased some raw LIFEPO4 cells, they were great. I love the fact that you are fearless digging into this stuff..
Yes completely agree their cases are brilliant very sturdy everything fits and they're great people to deal with. Also they have warehouses in Europe and America so the shipping is local and very quick.
Hi Sarah interest video, I liked your problem solving approach to diagnose the display fault, which by the way seems to be a dry solder joint on the display power pin, would be my guess, might be fixable. Whilst you were facing the camera the display, amusingly, turned on momentarily, and turned off as you turn to look at it. I could help but notice the power cut off switches on top of the battery packs. Good to see your going to swap out those round red switches, which was one of my recommendation a few videos back. I guess that is what your next video will be about, so looking forward to that. The air con unit is a good idea, much better than the mobile unit. Ours are in the loft space, not ideal I know, but that is were they have been for the last 2 summers, the first summer the ambient temperature topped out at 50c, but the batteries were only 30c so all was good, but I did install some fans that draw up air from under the floor boards directly to the Inverters to help keep them cool, and included a vet at one end of the loft space. Even though these events only happen 2 or 3 times a year in weekly intervals, its not really perceived as a threat, as the cell I have can cope up to 60c. I've event seen this temperature in our car battery pack on hot summer days when driving long distance. We are planning an extension that includes a battery / Inverter housed on the ground within the design. Cheers Ken
Why did you shut down all your solar production to use grid only? If I am not mistaken, the inverter wont care if the power comes from the MPPTs only. So, in my eyes swichting off the batteries should have been done the trick.
Well basically at the moment I've got the system set up to external communication meaning at the system is listening to the batteries so if I turn the batteries off the systems shuts down I could have changed the settings before I turn the battery off but I couldn't be bothered to be honest
Wow I'm amazed I've got people in Egypt watching my videos. I'm glad that you're finding them interesting... I bet you could generate some serious solar power over there in Egypt...
@Gridbusters-qx4om haha yes we have 3400 of sunny hours per year in Cairo and more than 4000 in Aswan. And yes I have an 11kw Eastman inverter and another 6kw inverter. I have 18 panels 550W each and on the way are 300ah battery. I can charge my BYD Atto 3 in 7 hours from the sun. And I run 3 air conditioners induction top etc. So like you I am trying to bust not only the grid but OPEC. I don't want my son to cross the red sea and dies to protect a hole in the ground. About 10 years ago I built a battery from rubbish of a computer mall. Old laptop batteries. We had unrest here. And my kids needed the Internet. So I built a 24V system and powered the the whole house. It was fun. I tought my son how to weld. Nearly 1000 18650 batteries. One day he will appreciate it. I hope.
i have just got Air to Air with a heat pump on a split system its really cheap compared to radiators and only took a day to install, Great for winter and summer .
I haven't really thought about that, but yes I guess it would be good for heating as well great if we have a really cold winter I'd be able to heat the plant room with it...
@@Gridbusters-qx4om I've only had it a week but i had been watching many RU-vid videos about them , it was cheaper than if i had the UK Government grant of £7,500 , this with only 3 cassettes and the heat pump was less than 5k . and so cheap to run , im getting a 2nd Powerwall 2 soon as the price has come down . I'm enjoying your project very interesting thanks .
That sounds really interesting I might be wrong but I think you can't get the government grant if your heat pump does air conditioning the government grant will only allow the heat pumps to do heating not air conditioning.
@@Gridbusters-qx4om You are right they dont do a grant for Air2Air but there is no VAT on renewables' , I'm not having a hot water tank either as i haven't had a bath for years and when i ask people they say the same . All that hot water you have to have to get the government grant , so im having two under sink water heaters that i probably wont even use a kettle is just as good .
You want to find an ac unit with two ports on it. An input and exhaust. I got mine for my grow room off of Facebook marketplace. But as I listen, yes a mini split would be a good idea. Check out the ones designed for solar. A bit more expensive but runs off of very little energy.
@@Gridbusters-qx4om The problem with most portable aircon units like you have is they suck the air out the room, so all that air going out has to be replaced, and that means hot air from outside the room is sucked in, hence Gordon's comment about using one with two ports. Mini split will solve the problem very nicely, and be much more efficient. Incidently one of my JK BMS displays stopped working a few weeks back. Your's looks like the back light is failing, or has a bad connection.
Check out the mini split systems used in the USA. Can you get one here? (France) Pre gassed for self install - Might be able to do it without getting expensive air con installers
I have pretty much the same cases....EEL with breakers and single terminals and no display. What do you need the display for when the BMS has bluetooth and an active 2a balancer?
@@Gridbusters-qx4om I believe the bluetooth is not part of the display module. It's in the BMS...well at least for my JK BMS. You probably have the Seplos BMS? I assume you are using the right app on your phone to recognize both BMSs.... Is one BMS working perfectly or are you having bluetooth issues with just the one with the funky display?
@@Gridbusters-qx4om If you haven't already tried, instead of just swapping displays, maybe try swapping the wiring harness between displays as well. It seems intermittent and those tiny wires break easy. Or put the questionable display with the good BMS and its set of good cables. Just a thought...best of luck. PS: I like the Victron gear.
@@Gridbusters-qx4om oh great.. I am using jk inverter communication bms, 150 amp one. With my deye 5kw single phase inverter.. I have this strange issue, while exporting to the grid, throughout the day, my battery drains by 10%. And if I don't export, battery SoC remains constant throughout the day.. Tried everything, different firmwares etc.. nothing helped..
