  1. Thanks everyone for your feedback.
  2. Hi Everyone I have 10x 3000C batteries and I am struggling with communications with my Deye 12kw inverter. I had initially bought 8 and the coms worked fine and then I bought 2 more and that's where my trouble started. The 8 batteries were made on the 11/2021 and the newer 2 were manufactured on 03/2022 plus they have different part numbers. Individually the both work fine with the inverter but connecting them together causes the coms error. I see on the forum updating the firmware of the batteries is an solution but before I try that route does anyone have a simpler suggestion on how to fix this problem?
  3. Thanks for the input guys and sorry for taking so long to come back to the question I first had. The answer is that you can use it in 2 phase but the inverter alarms go off and it gives you some error codes which includes the W03 error code. The manual states that when getting this error it means a grid phase error and to use 0/120/240 which I did and it works. I have tested the inverter in UPS mode but am getting strange readings when I change it to when I want to feed to my local grid. That said I don't have enough solar to fully test this. I hope this will be of help to someone with the same problems I had. I am still impatiently waiting on the municipality to install my 3 phase meter....2023 anyone?

    Deye 12kw

    Hi there boys and girls I have for the first time "installed" solar this week (basically just laying it out on the ground...the mounting kits will be delivered hopefully next week) and having had a silent system till now I am worried about high temps in the inverter. The fan kicks on at 51C+ and keeps rising until 53C when the fans ramp up even more and the temp drops to 49C where is silent again for a while while the temps rises and the cycle begins again. I have recently installed 8x 3000C pylontech batteries and the temps increase with the higher output of the solar as it charges both the batteries and supplies the load. Question 1 Is this normal Question 2. The rated charge current of the 3000C is 37A. I am getting up to 43A (possibly more as it was cloudy today and I only have 6 panels connected) Is it 37Ax 8=296A. The Li-BMS data says that its charge current limit is 296A. I know it seems self explanatory but Youtube videos give differing opinions and I would rather make 100% sure than damage the inverter. Thanks for your help
  5. As I understand it the first dip switch (1) is the baud rate and the second (2) is the master/slave. The manual states that the master dip switch can be left on 0. I have no clue if changing the baud rate changes anything?
  6. Hi there gents I have recently bought 8 Pylontech US3000C batteries and wanted to confirm that I just have to leave all of the dip switches at 0000? The manual is a little hard to follow. Thanks for the help
  7. Hi. Can a single 3 phase inverter be powered by 2 phases without causing damage to the inverter?
  8. Thanks for the response guys. I think i will go with the pylon tech and deye combo. It seems we are in for another series of load shedding and eskom is also busy working on the powerlines here where we will have an outage from 8 till 4 tomorrow. Yeah...just ***** great! Initially i plan on just connecting power to the deye via wall socket to charge the batteries then remove all power and use the the system as needed as a generator. I read somewhere Lithium-ion batteries can hold their charge up to a year....not that i am planning to do this long term (2-3 weeks) Following that i will install a db board with the K&N Single Phase AC Switch Disconnector 25A that comes with the kit and also include a breaker, surge protector and over and under voltage relay switch that goes from the db board to the inverter. I will get an qualified electrician to do the connection from the mainboard and to check connections. Between the battery and inverter the kit includes a KETO Battery Disconnector with 125A Fuses. Is it necessary to include a breaker here as well? Between the inverter and essential loads i already have a db box with breaker and surge protector. Any suggestions?
  9. Firstly hello to everyone on the forum i'm really glad to have found a lot of oke's willing to share their knowledge with everyone. I have been looking into doing my own solar setup for some time now for even though the diy route seems daunting . I'm looking into a system to firstly help me combat load shedding and run as an UPS. I do not want to feed power into the grid or go full off grid. For now i only want to power an essential load of a 1000w that needs to run for 4-5 hours in the event of grid failure. The initial system will be without solar only drawing power from the grid. I will install solar at a later date. I've made the jump from buying an growatt inverter to rather getting a hybrid inverter as well as choosing Li-on batteries instead of AGM and because of this my budget is wrecked! My first choice is the Deye 5kw inverter but after reading very good reviews of the Goodwe ES 4.6kw inverter i'm wondering if it is not worth the extra cost? What are the main differences between the 2 and is the Goodwe the more reliable inverter at the end of the day? Can either inverter when solar is installed be set to switch from the solar directly to grid and not use the battery except when the grid is down? My second conundrum is choosing between the Dyness 3.6kwh and the Pylon tech us3000 3.5kwh. I see most forum members use the pylon tech and that the dyness is a newly established company (2017) So i guess the pylon is the best choice? Will 2 of these be enough for at least 4 hours at a 1000w draw? Thanks George
