problem solved : Seems the breaker in the picture has burned , so it was on the Fritz....going out causing the weird trips. Replaced it with a new Breaker, hopefully the trips are at an end.

it is weird for the 22:55 trips........load is not high at that point .....about 900w - 1.6kw (see screenshots below) ......had a trip during the day today aswell....it seems the trip happens when incoming voltages kreeps up over 240V.....in the 243V+ range ...... might that trip a breaker ? the Voltage coming in drops then to 27V and not 0V ..........is that correct ?

I have now had two trip happening on a breaker switch, it is labeled as Eskom IN and has a 40A breaker. This breaker trips 22:55 at night.....(now two nights in a row) . See the picture below for the Grey/black breaker that trips . Could this be that the breaker is faulty ? Why would it trip if the house is running of Battery at that point and only the trickle feed is coming from eskom at 30w. is a 40A breaker fine for a 8800w inverter with the entire household + geysers running through it ? Surely I might pull 9kw or 10kw at points ?

This is my Setup for inverter, could be the Reconnect after trip settings not being setup ? Can anyone confirm their settings for this part ?

Thanks....will look at the other posts. I do leave it alone, and there are reconnects straight after , but a few times now it has not reconnected at all.......for hours on end during the night , running my battery to shutdown. Only after my intervention of flipping the breakers does it reconnect. This is my concern, I am more than happy if it disconnects and reconnects later if the power is in range, but it does not at this point it seems.

It is in busy times , more or less......looks like 16:30pm and 5:00am was some key times. also got a 12:15pm one. I did look at the setup and the range is very wide, 185v to 265v , and 47.5hz to 51.5hz , i have not seen anything near those limits in the graph data to be honest.....but it could be a small spike not got by the data polling interval of the sunsynk software.

Hi, I have a 8kw Sunsynk inverter with 3 x Pylontech UP5000 batteries and 14 x 550w Solar panels. This setup has been running smoothly and without a hiccup for 2.5 years. The last 2 days I have had the inverter disconnecting the AC load, feels like loadshedding or a powercut. However the Eskom feed is fine , streetlights are on and neigbours are fine. I basically then need to flip the breakers for the Eskom feed at my Solar DB board and once I flipped them back on then AC load is restored on the inverter. This has now happenend 3 or 4 times in the last 2 days. I also get the "ghost disconnects" where I get notified of the disconnect and immediately after a notification of reconnect to the grid. We have been the lucky winner of getting a smart prepaid meter, but that is now 3 months running. What can it be ? Is it the smart meter causing issues? I have upped the trickle charge to 30w from 20w , but still getting it. I tried looking at the graphs and logs , but the SunSynk app interval is an issue. I can see that the disconnects in the evening/early morning the Eskom feed sits at 240/244V , which is in range occording to me(there might be a spike I dont see in the data interval) What can I check ? Should I get an installer to come check things out ?

Looking for a voltronic clone inverter. 48v 5kw preferably.

Backup inverter kit Perfect for home office , and running essentials 24v system Powerstar IR 2kw inverter Pure sine inverter 2 x 12v monbat batteries 180ah Provides hours of backup Inverter can be fitted into db board Inverter has ability to accept solar input to charge batteries. Perfect plug and play solution R7500

did a quick test again , so think it might be batteries. below is how the measurements went : 0 minutes battery 78% and 25v 27 minutes battery 70% and 24.6v 49 minutes battery 50% and 23.4V 73 minutes battery 50% and 22.4V 83 minutes shutdown measured consumption over the more or less hour : 350-400watt. (0.35kwh) So it seems the batteries went to basically flat (22.4V) with 400watt consumed , which is not a lot to be honest. So I am going to try and disconnect the batteries and test them individually and see if there is maybe a bad battery * any tips how to test them ? Are these battery testers you can buy worth the while ? * if the batteries are dead, can I sell them for scrap/recycling ? who can I contact for this ?

I have attached the settings, the inverter does not have options to configure, it is all preset. Low voltage cutoff is set at 20v, so it should have been fine according to me, however the Inverter for some reason thinks the battery % is at 25%, so not sure if that is maybe an issue with the Inverter.

I have a Power Star Pure Sine inverter 2000w 24v. I have 4 x 100ah agm batteries connected. I mainly use it as a back-up in the office with 3-4 people working on it. Load is not too hectic ,about 500-600w an hour measured with a max of 1400-1500w (laser printer) The issue I have is that the current setup is not lasting the 2 hours of load shedding. I monitored it today thinking it might be the batteries that are shot. So loadshedding was ongoing this morning , load was 300w more or less, after about 40mins the Inverter stated the Batteries were at 70% and voltage shown as 25.8v .Literally like 5-10 mins after I checked the system shutdown and the inverter showing the batteries are at 25% on the little LCD panel. Voltage is still reflected as 25.8v more or less on the lcd panel. restarting the inverter still yields the 25% option. I then measured each battery and voltage was at 13.0v. * Could this be the batteries that are totally done? Should they not show lower voltage when shutting down the inverter? * Could this be an issue with the Inverter somehow? as the settings for the inverter to shutdown is set at 11v or something close to that (std settings not configurable). * best way I should test this ? try another inverter with the current batteries? * how do we test AGM batteries? Can I take them somewhere to do a test? like a batterycentre of sorts? Thanks!

I need some guidance and advise if I am on the right track with approach and thinking. I have been looking at getting a proper inverter setup integrated into the main DB with solar, but usually it starts small and before I know it I am down the rabbit hole and looking at 100k setups. So the current loadshedding has been the final straw to kick start the process, unfortunately it is the worst timing, as budgets are tight due to Covid etc. My thinking is to get an inverter and Battery setup that will be sufficient for my core needs to tide me over with loadshedding for the next 1 to 2 years and then maybe upgrade components as I go along. I dont want to waste money or buy double. So I have eliminated a portable type setup , it will be cheapest to an extend, but will need to move it around the house the whole time and there will be extension cables lying around etc, which is a risk with little kids. My core electricity needs : Daytime we have a home office for my wife's practice and I am working from home It is mostly 2 laptops and 1 desktop with 2 laser printers 1 small bar fridge in office 2 routers 1 60L fishtank with pump and heater Night time Routers and fishtank still 2 x led tv (not on at same time) with tvbox etc ability to put on lights (all globes are led) Strategy: So I figured I need to get my DB wiring sorted and setup, that will be needed regardless of the type of inverter or batteries I get.So I need to get an extra DB board, move out the lights circuit and the specific plug circuits that relate to my needs above. Leave the pool pump, geyser, kitchen etc off. Need all cabling and fuses and switches to get this ready. What would something like this cost? I have an estimate of R5000 for parts and labour? Inverter : This is the tricky one, obviously a nice 5kw Axpert would be nice and ideal, but it will stretch the budget and the 48v battery adds to the dilemma. I like the fact of an all in one setup, so the Chinese inverter was an option , but getting a seperate charger and plumbing it into the DB just seems more complex. So I have settled on looking for a 3kva 24v inverter. I am looking at an Axpert or Axpert like inverter. I am looking for a 2nd hand model if possible. I can get an Inkwenkhezi model for about R4000 , which looks decent and ticks the boxes . Is this a good make? Should I rather look for an Axpert / RCT , they are 6500 ish and up? The model I look at has PWM and not MPPT, is this an issue? I might look to add a few panels later (say to the 1500w max of the inverter) Will the PWM part be able to supply the house with power after the batteries are charged ? The inverter will be sold later and upscaled to a 5kw Axpert Batteries: I would like Lipo, but feel it is overkill for now, With the immediate need being load shedding and me not cycling / using them daily. Will upgrade to them eventually. My thinking is i need 2 x 200ah batteries at least, this should give me 24v x 200ah = 4800kwh . Taking 80% efficiency it give me 3800kwh more or less and if I go down to 50% DoD it will give me 1900kwh usuable power. This will be about 950kw per hour for each 2 hours of loadshedding. this should be enough to drive my core needs easily. seeing as I am going to upgrade later and looking for an interim solution of 2 odd years and for loadshedding mostly, I figured I could get middle of the road batteries, not the best and not the total worst. Was maybe looking at getting 4 x 105ah Royal batteries? should add up to about R5000 in cost. Should I rather look at getting 2 x 200ah batteries? I see you can get Ecco and Vision batteries for R3500 each, which would total R7000 I am looking at the batteries as "throw away" want to use them for the 2 years, and then they should be done, not really reselling( who would buy 2 year old 2nd hand batteries in any event), so trying to get the cheapest option that would last the 2 years. Am I smoking my socks with the above setup ? or should I rather wait and get a 5kw/lipo setup. I reckon at worst I would lose the battery costs, the inverter I would be able to resell and recover some costs and the installation will have to be done regardless of the setup I choose. Will this mean I can have a interim UPS setup for about R15000 Will electrician come and install the inverter and do the DB work if I dont purchase the inverter and batteries from them ? Is it better to take a package deal, where they do the install and provide the products?
