I can try 5&6, but it sounded like everyone has come to the agreement that for the 5.5 KW inverter it should be 3&4. Yes. Apologies, thought it was an 8kw inverter. My bad.

July 30, 20233 yr 19 hours ago, Chockies said: Last question to check my understanding - When you change the system mode to "Limit to load", it then uses an internal CT coil and does not need the external one, right? With the sunsynk/deye inverters you must always have the CT installed ( Correctly at your incoming eskom/utility live line before other circuits ) to ensure everything works correctly.
August 6, 20233 yr Quick update on my situation... I took a chance and went straight to the Sunsynk service center and asked if they can please test my CT Coil - Ten minutes later they came back and confirmed it was faulty and gave me a new one, no questions asked! Hooked it up today - And everything is working as expected!! 🥳🎉 Definitely best to test with PV off - Can confirm that if your little Eskom smart meter says you are using 1.4 kW, then the CT reading on the inverter must also show 1.4 kW. I noticed there is a variance of about 10 - 20 watts, but believe this is ok

Will check tomorrow if the CT is sitting on the UPS load side and not the feed from the grid. Or did RiazM return his inverter to the supplier and I got given that faulty one instead? ( Yes, I'm that cynical..! ) Just check your CT Ratio value in Advanced menu.

The inverter will not show it's own use to operate and at times it's own use could be split between grid and battery use.
September 1, 20232 yr Hi , I have a Sunsynk 5Kva invertor with 10 x 455 panels and 2 x Revo 5,1 Kva batteries installed and having issues , no support from installer hence my request for assistance on this forum. During load shedding the system is drawing the load from both the Solar and Batteries but during normal Eskom power it draws almost nothing from Solar and uses grid instead which is costing me money . I went through a few videos and noted the mention of CT coil but I dont see this unit displayed under system flow chart settings in my invertor. Would this be the reason why the invertor is not drawing from Solar but grid instead? I also note that AGM has been selected even though I have 2 Lithium batteries with BMS instead of Lithium. Thanks in advance.
September 8, 20241 yr I am preparing my installation at home for the connection of an 8kW Sunsynk inverter. Can someone give me the dimensions of the reverse power blocking CT. I need to know how much space will be required to fit the CT in the Main Distribution board between the meter and the Main Switch.
December 12, 20241 yr Hi all I have a client that had a sunsynk installed by a other guy . Ct coil is the right way and I have gone through all the videos and manuals. I am getting a 31 volt , between 4watt to 55 watt on the ct but the grid is off please can someone help it is driving me crazy . I am thinking there could be a back feed coming from somewhere Thanks Gary
December 13, 20241 yr Have you got an analogue voltmeter (old fashioned type with a needle) or a tester with a low-Z voltage range? If so redo the test and see if you get a different voltage reading.
May 7May 7 Hi allCan anyone help with the settings on a Sunsynk inverter both Voltage and Amps for a 3kw and a 5kw turbine please
