Gerrie Posted August 21, 2021 Share Posted August 21, 2021 Just replaced my Axpert with the Sunsynk 5.5 situated in my garage, It is powered up and everything seems to work first time, still a bit of reading and experimenting to do with settings and WiFi dongle that I need to figure out but “WOW” what a machine. Everything about it feels and look like quality. It was quite easy to fit as most of my wiring was already in place except for the CT coil wiring that was a bit of a mission because my grid main cable is about 20 meters away from the inverter and I had to extend the CT coil wires to reach all that way and than changing my PV panels from parallel strings to series. Than fitting the earth bond relay easily inside the inverter, Also my DB in the house was previously upgraded and split into three sections when I first installed the previous Axpert. I did’nt use the PV string connectors on the bottom of the inverter but rather entered the PV wires through a sprag pipe in bottom of inverter.

Gerrie Posted August 21, 2021 Author Share Posted August 21, 2021 The DB is bit cramped because of lot of circuits but still good Quote Link to comment Share on other sites More sharing options...

When I bought my panels at a shop the other day , my eyes caught a rugged piece of machinery on the showcase wall. Approached it and it identified itself as a SunSynk 8kw . What a presence! Seen a lot of images of it here, but those images do not do justice to the physical presence of this machine! I am committing cardinal sin : my mentors of years ago taught me a fundamental rule : an engineer must never 'like' something , he/she must always judge purely by facts. But I do believe the sunsynk is an exceptionally robust product . Quote Link to comment Share on other sites More sharing options...

True, my wife brought my 5KW home and she said I can go fetch it in the car boot, for a moment I thought she got the wrong thing when I saw that big heavy box. I can just imagine the 8KW, guess guys better think where they gonna mount that beast. It’s still very early days for me to judge the Sunsynk but having worked with lots of cheap crap in my life this was not one of those moments.

Gerrie Posted November 2, 2021 Author Share Posted November 2, 2021 The Sunsynk has been running for a few months now and no complaints. Now that it’s been running for a while I was surprised to see you can run a 3KW geyser element with only 1 x US3000 (set to 1.8KW maximum of course) and plus taking into account my undersized 1980W worth of pv panels. At midday with nice sunshine it does not need any grid blending except the 10W grid feed-in setting that I have setup. It will be hard for me to justify more panels with my little usage. I need to get a extra battery for night time though. Below 3KW geyser load on at midday and it’s on a timer for 20minutes at a time.

PowerUser Posted November 2, 2021 Share Posted November 2, 2021 How do you get the battery to show on that screen? I don’t have PV yet but I have a battery, which does not show as yours. See below: Quote Link to comment Share on other sites More sharing options...

I’m not sure it worked from the start, it might be in the plant settings that you have something that needs a tick. Quote Link to comment Share on other sites More sharing options...
JUA Solar Posted September 1, 2022 Share Posted September 1, 2022 Nice Install. Curious to know which comms cable did you use between the inverter and the battery? Thanks Quote Link to comment Share on other sites More sharing options...

Lee2 Posted September 23, 2022 Share Posted September 23, 2022 What are all those plugs and lightswitches for next to the inverter? What powers them and what in turn do they power? Quote Link to comment Share on other sites More sharing options...

I did not fit a isolator like most installers do I decided on a socket so if I unplug it there is no Eskom power to the inverter and its than completely off-grid.

That photo is bit old I did install a new DB next to inverter, that was just a temporary little board in beginning to get my solar going.

Sorry maybe a stupid question, if you feed your inverter with a 15 Amp plug, you can only get 15 Amps to your load when you on Eskom, the 2,5 mm2 can only safely carry 15 Amps Quote Link to comment Share on other sites More sharing options...
Gerrie Posted September 23, 2022 Author Share Posted September 23, 2022 You are correct I never go more than about 10A my loads are managed with Sonoffs and Astute’s. I still have to swing the inverter cable over to a isolator the red plug was perfect with my old Axpert but the Sunsynk needs a isolator.
