Hi guys

i need some help with my inverter hopefully someone can help.

I bough a Sunsynk 8kw inverter and installed it. Currently running without batteries still need to connect them up. Settings was changed to no batteries. Inverter did not like that came up with a F13 fault, had to reset all faults cleared.
Grid is connected to grid on the inverter DC switch on, green button pressed in. I still need to fault find the solar as its not showing im generating anything(for another discussion) 

the CT is connected in 5/6 plus being white and black negative. I am measuring 30mV coming from the CT. (I have swoped it around as read in previous forums suggested still does not work.

The problems i have is the CT is not showing any watt value.

On the top left corner of the display it shows off in green is this normal?

I will fault find the solar power over the weekend maybe i wired a plug incorrectly. 
 

Sunsync technical support did not help much.

Any help would be appreciated.

<Hi. As far as I'm aware. If you set it up without a battery. You only connect the mains power to Grid. Nothing can run via Load. It becomes Grid tied. CT coil must be on Eskom side. Arrow facing towards the inverter. Hope this makes sense. 

Hi Craig

i had it connected like that my CT shows no measurement and i am reading mV coming from the CT. 
 

now i have my house connected on the load side of the inverter and its showing im pullings amps but no watts

I  have a 8k running in Grid Tied mode.

Had the F13 fault initially. 

Set it up as No battery and mains on the Grid Input - worked immediately.

Even without the CT coil connected.

Maybe do a Factory Reset and try again.

I agree with @Craig Pottinger in that you can not connect to the Load Port.

You say "In top left hand corner it show off" 

You need to push the power button to turn the inverter on. 

Just because the display is on doesn't mean the inverter is switched on. 

@Colin B, that is a very astute observation, @Vegeta84, did you check that 

Hi Guys 

managed to get it working setup and wiring was correct. 
if there is not DC present from solar or Battery the inverter goes to limp mode and all the readings do not work 

@Vegeta84, was thinking about what you said above, last Sunday i installed a Sunsynk as a grid tied ( no battery ) for a client and at night the AC and NORMAL led's are both lit up and inverter shows all the readings, except of course the DC led & readings for solar, will be interesting to see what you get tonight.

@Tariq nope when my DC falls away the inverter goes into that limp mode and all the measurements stop working. This morning when the panels produced some power it came on again.

Thats the same thing i had without batteries, with a battery the ct works during the night as well now.
