  1. Thank you @TonyH, there is no mixing of AC & DC cables in the trunking. The battery cables run upwards and jump over in flex conduit. The AC cables run alone in the horizontal trunking. When I install my solar strings they will run in their own trunking.
  2. Thanks @ianm I tried finding some reference from Keith but clearly missed it. This would have helped. @Brani yes confirmed, CT connections to be in installed on 5-6. I hear you kn the level of nervousness Last night after a final check and ensuring that my earth-bond relay was engaging I switched ON. All good and running nicely as an expensive UPS for now. Looking forward to the solar installation next... Thanks to everyone for your assistance!
  3. Meant to say that 'N underneath the terminal block lines up with L2 on the PCB...' Note: I now know that the markings on the PCB's are supposed to be blocked out, but this is exactly the point of my comment that has not been done sufficiently. Looking at my photo one can see that they have tried to blank it out, but its not so evident when you are actually looking at it...

    Hi @Speedster I have the 18A...
  5. SunSynk 8kW AC Wiring Morning all, This morning I was going to post a question pertaining to the AC wiring of the 8kW Sunsynk but decided to rather contact one of the Master Installers listed on the SunSynk website to clear up my concern. It does not sound serious, but after having chatted to Shane (Solar Electric Wise), he confirmed the confusion is real... Attached is a photo of my AC wiring for GRID & LOAD on the terminal blocks. Take note of the markings on the PCB as N, L1 , L2 (suggesting two phases?) whereas underneath the terminal block it is marked as N, L. Now thi

    @Vassen how would you know if you’ve bought the newer model? Where can I check? Week before last I bought an 8kW SunSynk at a great price and it came with the WIFI dongle.

    Managed to get one from ACDC Dynamics in Pinetown. Good price too!

    Hi @Vassen Thanks for your assistance. 1. Noted. 2. I'm going to install the SPD directly to E while i research further for interest. 3. Sorry I did not explain myself to well, i should rather have said when you merely want to by-pass the inverter. I'll have a look for the electrical diagram that you refer to. If this is merely the function then i have taken care of this with my 4-pole ON/OFF/ON 63A rotary isolator which does the same trick i.e. Isolates the inverter and bypasses Grid to Essentials DB. 4. Thanks for confirming. The chaps at ACDC Express were a bit stun

    Hello All, With reference to the SunSynk Protection Circuit show below, i have the following queries and would appreciate your assistance please: Question 1: I would like to confirm the size of the Supply & Load MCB's for the 8kW SunSynk. I have seen numerous discussions about the 5kW which is 35A. Depending on which Installation Manual you consult, i typically get the following: 5kW Max. AC Output Current: 25A Max. Continuous Passthrough: 35A 8kW Max. AC Output Current: 40A Max. Continuous
  11. Nice install @Kill_switch I am about to do the same thing with the same equipment. Just some questions on the battery connection: 1. Is it not better to connect the two batteries using 25mm2 cables of the same length at a common junction / busbar and then take it to the inverter using 50mm2 from there via the circuit protection? 2. The manual recommends a 350A DC isolator in series with 250A fuses. I know you are current limiting and agree with the discussed rational for your 200A fuses. But is it good practice to rely on pulling fuses every time you need to isolate power to th

    Okay, so I did some more reading and I came across another discussion regarding Fusion vs Deye where my precise question was addressed. https://powerforum.co.za/topic/7465-fusion-hybrid-inverters-5kw8kw/ Advice offered by @Vassen is that SunSynk support is far better. @Craigm did you go for the Deye from SolarAdvice and are your receiving expected support? I haven't seen any comments about direct Deye or alternative brand support quality? Thanks Trevor

    Hello All, I have read most of this forum thread, so excuse me if i missed it somewhere. I know that the Deye / SunSynk / Fusion inverters are one and the same merely rebranded but all emanating from the Deye factory. What i would like to know however is if the support channels are all different? @Johann1982 I noted the efforts that you went to in order to get support from SunSynk. Did this come via SunSynk or Deye the OEM? Perhaps someone can shed some light on the various brands and the support channels that exist? For example, I note on the SunSynk website that Ellies & Herho
  14. Looking at the data sheet it’s saying that Recommended is 37A but Max is 74A. So surely for the instance I’m explaining about 3x 74A = 222A which is even better! We’re talking about an event that happens 2-3 times per day for 3-4min.
  15. Hi @plonkster Thanks for this, but my main concern is the ability for Lithium-Ion batteries to handle Surge Currents in excess of their rated Maximum Discharge Currents. So with 2x US2500's connected in parallel this would provide 5.1kWh delivering a maximum 112A (continuous) or 224A (15-sec). So what happens during short term over current situations drawing say 7kVA of power which should be pulling 145A from the batteries for 3-4 minutes? How do the Pylontech's and similar Lithium-Ion batteries handle this? Do they trip or just keep push current like my flogged AGM's? Thanks,
