UK Solar inverter problem?

[Poppymac]

Looks like the solis is in control here, assume that the display is from the solis. What is the model no of the solis?

 

[Poppymac]

Mmm not sure. I can see the serial number on the info and it says Model number F6 software version 330023

There should be a data plate, probably on the side of the invertor casing, just take a pic

Ok thank you. There is a plate but my phone won't let me take a pic as the cupboard is too dark. I'll try tomorrow and get some light on it. Thank you

Just found this on the Solid site, does this sound correct?

F6---4kW single phase Energy Storage Inverter。

Yes but the devil is in the detail, so you need to know exactly what Solis product you have. Basically, the output of the solar needs confirming with a clamp meter and the load of the house ditto, against what the display is showing, only then will you know what is wrong. I cannot help until i know what product you have and access to the installation manual for CT locations against what has been installed and what settings have been put in the commissioning parameters of the invertor.
What you should see is:
1. PV output A/C correctly measured
2. House load correctly measured
3. If PV is greater than house, battery charges
4. If PV is less than house battery discharges until exhausted (like at night)

cheers

Thank you I understand. going to grab a torch to try and take a photo of the panel. I understood as you say, that the battery would kick in once solar produced is less than what is used, but as the usage rises when the solar rises and usage goes to zero when solar is not produced the battery never kicks in. ? Off to try

Is this enough for your needs?

Nice system !
Here is the manual RHI-3K-48ES-5G - https://www.ginlong.com/rhi_inverter1/1952.html

Your display indicates that the installer has made two connections to your fusebox, one for house and one for critical loads, hence the picture of a house and light bulb. There is only one CT which is measuring grid incoming/outgoing power.

Look at Fig 4.8 /4.9 and see if this represents how your installation is wired. If you look under the Solis, there are two connections , one for Grid and one for critical loads, be interesting if both have been used. I suspect they will have to come back physically to check over the connections.
A photo of the CT would be useful just to see how it has been connected
