That looks OK, if you turn on the kettle and oven, you should see it pull from the batteries

Well exactly what I said to the installer.At night i would expect the batteries to run down powering whatever is needed. As long as the batteries are flat before the Sun comes out, i guess it does not matter
I haven't had a chance to read this in depth, but the fact that the battery hits 80% and stops discharging could indicate that the depth of discharge setting is too high. Generally the installer sets the system so that 10-20% of the battery is not used, as even though lithium batteries can be discharged very low you buy quite a bit of extra life for them by allowing this buffer. The installer or Solis tech should be able to see the setting remotely. It could be as simple as they thought they were setting it to stop at 80% DoD and in fact were setting it to stop at 80% capacity.
Sometimes a factory reset and reconfigure can help.
Most likely something that has already been looked at, but thought I would mention it!
Can you take a pic of the display when it is in that state, i.e. your are clearly drawing power but the batteries are not contributing
Thanks both of you. I've got videos but I'm unable to attach them - only photos are showing when I try to attach.
With regards to the settings, it is strange.as before the new emeter was installed (before it gave up the ghost completely) for 12 days it was working perfectly. The system was installed on the 9th June.
I will try and take a photo tomorrow as the battery is at 83% at the moment and is powering the lights and fridges although I have to say that the power is jumping either to or from the grid constantly since we are using just battery power.
Yes thank you. The lightbulb is back as the installer asked me to do that last night as he said the reason the grid was jumping on and off was due to that, as the clamp couldn't pick up properly with the lightbulb off. Didn't make any difference whatsoever.I see that the critical load is back (lightbulb), its got to be in the parameter settings as there is clearly a load for the batteries to contribute to, but it has decided it does not want to.
I would try and contact Solis again and see if they will dial in and go through the parameters.
