Hi, 

Please explain how this screen works?

- System mode (Please suggest best possible settings)

- Battery setup > Shutdown screen.

 

 

Do you have the CT coil installed ? Do you have non essential loads?How much solar do you have ? What size battery?

Perhaps take a look at this video of the Deye setup.  It will give you an idea of how a similar setup would work.

 

Here is a video going over some of the basics of the Sunsynk inverters:

 

Hi also new to this. UK based . 3.6 Kw Sunsynk inverter. 10.24 kw Sunsynk battery. Confused by menu. I have a Time of use tariff. Cheap electric 00:30-4.30. First issue is that timing only run on one hour slots.

Have set to charge from grid between 1-3am, so missing out on 1 the of cheap tariff.  Only seems to charge at 2kw and reaches 6-7kw at end of that slot. So second issue. Why is it not charging at 3.6kw.

System was retro fitted to existing panels (4kw) with own solar edge inverter. Data about generation is not displayed on the Sunsynk menu. Not sure if there is a way to rectify that without interfering with the feed in tariff.

Lastly there is a long distance (25m) from garage where batteries installed to main incomer, so CT coil wire runs through underground conduit extended with UTP network cable. Getting weird results during day. Lots of power being sent to grid from panels rather than to battery. 

I only want solar export when battery full. Note feed in tariff in uk pays based mainly on generation. The export element is paid based on guesstimate that 50% of generation is exported. But it pays on both elements even if nothing is exported, hence need to minimise exports. 

I would welcome some advice on system mode page and battery setup. 

Also heard Keith Gough mention alternative to CT coil using a meter. 
 

Advice would be much appreciated.

Hi did you get this sorted? I'm in a similar spot.

 

hi we have lithium battery  x 2 

each 56volt  BMC is working

on battery settings: equilibrium setting is set to 55.5 volt and 0 days and 0 hours...is this correct?  thank you

Hi, I got a 8kw Sunsynk Inverter installed, but if zero export is selected, so that we power the non-essential load also from solar/battery if eskom is on, the reading on the inverter go hywire. Getting zero load figures and pv figures also go up and down and grid go to negative. Sure this is not right. Is this a problem with the ct install or other settings that is wrong?

I had a similar problem and only got it properly sorted when I finally got a smart meter.  I also have a long extension on the ct coil which was giving wildly inaccurate grid readings causing the inverter to send lots of power to the grid. In the end setting the ct ratio to 2300 and grid trickle to 500 actually results in about a 20w trickle average and much more effort use of solar and battery. I just live with the useless grid usage numbers on the inverter. I assume it's down to interference on the long cable.
