UK Solar inverter problem?

[plugsandsparks]

Oh and this is a relatively new concept as its wants to power the critical loads "off grid" - this would require a bit of re-jigging of the fusebox / a second fusebox - so i am now curious how they did it

Hi I'm glad it's a good system just a pity it doesn't work ?
We have a very old fuse box and i did ask them if it should be changed, but they said no they were just adding a small one just for the system. See photos. Then when the battery didn't charge, the instal manager said it was due to the old fusebox, had the same problem at his place, he said. Just turn the clamp. As I said, that worked to charge the batteries but did not stop the other problems not did it allow the batteries to be used.

I think i can see the critical load connection, it is marked A/C Backup, there is also one labelled A/C Grid, be interesting to see where those cables from Solis actually go. They should go to separate "fuse boxes" and did they ask you what you wanted wrt stuff to keep on if there is a power cut, maybe lights ?

Definitely something wrong with the math on your display, lol

Hi thanks. The wires come down through the ceiling in a conduit (another gripe). No they did not ask. Electrician had loads of problems getting the wires down from the cupboard upstair to the meters in the hall. One new fuse box. I'll try and take a video when I get home, I took one but don't seem to be able to find it ?

Ok but i dont have knowledge of that model to help diagnose the problem but i can see its not right. It is either the CT is not giving an accurate account of the grid incoming / outgoing or the parameter settings on the solis are not right. I have had similar problems with batteries not either charging or discharging but it was a much more complicated system involving multi vendor. As this is all Solis, it should work almost out of the box. The installer needs to come to site preferably when he can call tech support for assistance. When he does come back you can ask him what loads are on backup...

Thank you IF they come back. They are not answering me now?

Ok so I've taken more photos. The wires come down and into the new fusebox can't see wires going into the counter showing import and export, but it's right up against their fuse box.
Two grey wires come out of their fuse box into the two small boxes on top of our fuse box. Earth wire goes to the earth and a clamp with black and white wires clamps onto the red wire that goes into the fuse box.
Whilst I understand you cannot give me a solution, you have helped me know that the system is a new kind of inverter and you said it was 'nice', putting my mind at rest that isn't a bad system. As it is new type, I am assuming this is why they are having a few problems. I know what to say to them, thanks to you. I'll let you know what happens ?

Well solis are massive in the inverter market and an integrated single box solution for battery storage (now with off-grid working) is basically what has been needed in the market. FWIW Solar companies can be hit and miss with respect to service. When this system is working you will be impressed how the battery fills in the cloudy moments and extends the solar day. Hope it works out
