  1. Hi Krish, sorry I missed your post, for some reason I did not receive a notification. To answer your question the difference in price between a 5kw and 8kw is more than R10k to my knowledge. I doubt whether a good electrician will charge you more than that to fix up a common neutral issue? In the end I spent about R3k to get it resolved however a lot of that had to do with a lack of experience on their part and different guys had to come and troubleshoot. Basically I learnt the following from the guys that solved it. If you split your circuits, the test to determine if a common neutral remains after installation. Switch off Eskom at 63amp breaker in DB. If you test a voltage (230V) between Eskom neutral and the inverter output live you have an issue somewhere. Bare in mind this issue can also be some kind of earth fault on a light circuit or similar. Deye/Sunsynk inverters can be remote controlled but the factory only releases this protocol on special request. You can remote monitor no problem with the Solarman APP. Installation - difficult question. In theory not difficult to install, but if you encounter issues then you might get stuck.
  2. You need to send your logger and inverter serial number to Sunsynk to request update. I suggest you go to Sunsynk website and send your details to the customer care e-mail address. Or ask your inverter supplier. Most of them are on wechat/whataspp groups with the factory/technical and they can request your download. The factory pushes download to your inverter via logger.
  3. I think where the 5kw Sunsynk pips the Goodwee on features is a higher backup power rating of 5000W continuous and 10 000w for 10 sec. Colour touch screen. 120A battery charge and discharge. Extra auxiliary port which can take a generator input with auto start. Same port can be AC coupled with a grid tied/micro inverter. MPPt to control wind turbine and the parallel setup. The software can control an earth bond relay from a function port, which to my knowledge a Goodwee cannot do at present? The Goodwee is Super silent as it has no fan and their app interface looks a bit better. Is the Goodwee support good? I have heard of a lot of issues as well.
  4. Hi Pieter Johan from ICC to my knowledge is working on the protocal for Sunsynk monitoring. Give them a call. BMS software for Pylontechs is built into the inverter.
  5. Hi NC 20. Initially I did not have a great time with the inverter but this was due to a tricky wiring fault in my house that took ages to diagnose, find and resolve. If you are splitting your circuits into essentials and non-essentials with inverter taking care of essentials loads only, any common neutrals and or earth faults not on earth leakage (lighting etc) can cause havoc with the way the inverter measures power. Once that was fixed the inverter works a charm. The devices are fantastic but there is still a steep learning curve with regard to technical advice and after sales service from the suppliers and installers.
  6. Hi NC20, I have this inverter purchased from Ellies. Just FYI mine states maximum PV array power is 6500W and max PV volts 500V. I think their spec sheet may need updating. Battery charge and discharge at 120A. I have pasted the info sticker stuck on my inverter below.
  7. Hi Francois It is on 110 cycles at the moment and is about 1,5 year old. It has a 10 warranty period to my knowledge. Spec sheet sais "more than 3500 cycles at 100% DOD", but mine has never gone that low. Normally around 60% or higher during load shedding. I think on 80% DOD or less it should have a life of 4/5 thousand cycles. Mine has a 92,4Ah remaining which does seem like a fast degradation to me. I will get in contact with the supplier
  8. Hi All I have a Narada Lithium battery (48V 100ah) connected to a hybrid inverter. It has been used for about a year and half now for load shedding backup purposes. In the last 3/4 months I have noticed the SOC on the batteries own internal BMS screen is gradually dropping down even-though the float voltage is maintained correctly as per specification. It drops about a 1% a week. The manual states 51,75V for float and 54V for charge I tried a test discharge a while back all the way down to cutt-off voltage and that did reset the SOC back to 100% upon recharge, however subsequently it started gradually dropping down again and is on 89% at present. The latest discharge and charge cycles have not worked to reset SOC back to 100% What is going on? Should I be worried? Time for a warranty claim?
  9. Hi NJS, I have a Sunsynk inverter. To my knowledge the INGE inverter is an alternatively branded version of the Sunsynk. The hardware is the same and all of them are manufactured by Ningbo Deye Inverter in China with the following branded variants - INGE, Sunsynk, DEYE, OHm, and Sol-Ark.
  10. One could use a contactor as you suggest with a 60 second time delay on or off auxiliary add on. Then no need to get a signal from inverter.
  11. Thanks, I don't think my Sunsynk inverter will work properly with permanently bridged neutrals.?? It had a serious load power measurement issue until recently, which was resolved when we sorted out some common neutrals and earth fault problems between backup and non backup circuits etc. I am thinking about going the contractor route to link earth and inverter output neutral. At least the risk of non-compliance with SANS is reduced to 60 seconds only while inverter synchronises to the grid before reconnecting. Load shedding seems to be a distant memory at the moment. Apparently Sunsynk are working on something to resolve this issue. It might be in a software update which can send a signal to control a relay. But where does one find a relay which would accept such a signal?
  12. @Fuenkli did you ever get feedback from Goodwe on this issue?
  13. Hi Gerhard My battery is a Narada which is not compatible with BMS. Apparently the ones that work at present with BMS are Solar MD, Freedomwon, DYNESS and Pylontech. No list of compatible batteries included in the manuals. The suppliers should have a full list. If you go for the Sunsynk branded version it shares a menu structure that is very close to the USA Sol-Ark version. Sol-Ark have an excellent youtube channel that in my mind is the best source of information I have come across on how to set up the machine correctly and exploit its amazing set of features optimally. (Obviously ignore their 120v split phase power standard). The Deye, Ohm and INGE variants have a slightly different firmware and menu structure but in principle all work the same. I have a few recorded video demonstrations on how to use and set up for them. Send me an e-mail and I will respond with the recommended suppliers/installers in Pta. [email protected]
  14. Hi Gerhard This company in china https://www.deyeinverter.com/ manufactures the Deye inverter. In our market we get a 5kw and 8kw variant. In RSA you get the original Deye branded version, a Sunsynk branded version, an OHM branded version, INGE branded version and for interest in the USA they have a Sol-Ark branded version. There might even be more. The Deye data sheet you have come across is accurate for the specifications https://solaradvice.co.za/wp-content/uploads/2020/03/8kW-Deye-Sunsynk-Hybrid-PV-Inverter2020-Datasheet.pdf. Was it this one? I have a 5kw Sunsynk branded unit and I am very happy with it. I had some installation teething problems that took a while to sort out especially over lockdown, however this is all resolved. Unfortunately, there are a lot of inexperienced Solar/electrical installers out there who do not truly understand the correct wiring requirements for these type of hybrid inverters and even less knowledge of how to resolve things if a problem is encountered. The installation manuals are also a little light on detail. You can use any type of Solar panels with this inverter. It all comes down to the panel specification and how you wire them to stay within the inverter's range. For example I have 15 panels of 335W each. Each panel has a max rated current of +- 9 amp. If you wire 6 of them in series your Volts would be +- 240 V but the max amps would not exceed 9A which is well below the 18A maximum. You could wire two strings in parallel and you would still be within the 18A (9A + 9A) range but I will leave the technical details to the more experienced on this forum. You are welcome to get in touch if you have questions or need further information about these inverters as I have learnt a great deal about them over the last 2 months.
