  • Sunsynk 5kw x2 or 1x 8kw/10kw.

    Good day... I currently have 1 x sunsynk 5kw ( SUNSYNK-5K-SGO1LP1 inverter ), two Sunsynk Sun-Batt-5.32 and 12 x 450w panels. I am wanting to upgrade the system, so either buy another 5kw inverter or sell the 5kw and buy a 8kw or 10 kw inverter (Sunsynk). I did purchase the original Sunsynk 5kw inverter from the Powerstore sometime ago ( + - 5 years ago) and am worried that the current Sunsynk 5kw inverters are not compatible with the old ones when setup in parallel format. Anybody have some advice going forward?

  • CoC in a thatched roof house

    Hi AllWe are having a problem with electricians providing a quote to CoC our holiday home.It is a thatched roof and some of the wiring runs close to the thatch without being in conduit. This must obviously be remedied but the difference in opinion on how is about R40 000 worth.All or most of the wiring is twin flex. One guy wants to rip all the house wiring out and replace with Surfex   the other wants to just encase all the twin flex in conduits, and one in between with some Surfex and some conducting.Is there a definitive specification in the regulations for thatched roof house wiring and where do I access this please.Will eventually be going solar, with the panels on top of the water tower and car port, but for now it the CoC problem.

  • Sunsynk vs Victron

    I have a 8kw Sunsynk 10kw inverter with 18 550w north and west with 3 x Bslbatt 5 kw batteries My neighbour around the corner installed 2 x 5kw Victron inverters with 16 panels and 4 x Freedom Won batteries. At the same time during the day, his solar panels deliver 5 to 6 kw whereby mine only hover at 3 to 3.5kwI have posted about this before but never actually got an answer. Must I just accept that Victron setup is better than Sunsynk???

  • Solar enthusiast here

    Hi everyone I am quite happy that I stumbled apon this forum. I have found some very useful information already. A bit about my systems: Hooked up to the house: 3KVA SRNE inverter 5 x 450W panels 1 x 24V Easton lithium battery Running (or used to) my office: 1KVA ACDC Inverter (Asperix MKS) 1 x 330W Panel 2 x 12V Deep cycle lead acid battery's in series to make 24V State of the systems: The 3KVA system is a new install. Yes I do need to add another battery to the system as I run out of battery at 2am every day. (Budget only allowed for one at the moment) The 1KVA is 5 years old and the batteries died on me in the last month. So I am in two minds at this stage, sell the system and buy another battery for the 3KVA or do I just replace the batteries on go on. Any wisdom or thoughts on this would be appreciated. Extra: I connected a raspberry pi to the 3KVA Inverter and put together a go lang app to read the modbus information. I collect it with prometheus and then display it with Grafana. Was a very fun little project. All is running on the Pi4 without any issues. Next is to push that information to Cloud IoT through MQTT.

  • Inverter comparison 2025 - Help me choose

    My current system uses a 12kW Single Phase Sunsynk Hybrid Inverter with Volta Stage 4 Battery. I am very happy with my setup, even through I need to add one or two extra batteries.I'm looking to install another 2 systems for family sometime soon. I'm also looking to potentially upgrade mine as I switch to EVs. I can always go with sunsynk for the new installs, but my installer has warned me that they are starting to experience long lead times for repairs (he took one out the box not too long ago... it was faulty, and sunsynk took 9 weeks to repair it). Perhaps they are getting pretty popular and this is putting pressure on repairs, I dunno. So far, I've had no issues with mine.One option I have is to switch to Sungrow and move to a High Voltage solution, then move my system to my parents place as my inverter / battery combo is more than they need. Downside is that the only sungrow inverters that work with Batteries are maxed out at 10kW. So I'd need to install 2 of them, and then I would no longer be able to feed back into the grid as i have a 60A breaker and need to stay below 13.8kW.Then I was looking at the Deye units... they are a bunch cheaper than Sunsynk, and they seem to have a new app now? From a cost effectiveness perspective, it's attractive to look at Deye, when they are essentially the same hardware as sunsynk.So... question time.Does anyone have experience with Sungrow?What's the support / app experience like with Deye in 2025?
