Solar not charging to battery
No idea. This forum is just other users trying to help each other.
Helps if you can tell us what kit you have, what tariff you are on and a better description of what is happening.
Perhaps the battery is full, or the solar is being used by the house demnd
Oaks was working, now not
Did you change something, or did it spontaneously stop working?
The activity log on the portal might reveal something.

Oaks Posted at 9.00pm. Perhaps the sun has set?
The obvious things would be battery charge rate or pause, does it still charge from the grid? This assumes you are on a multi-rate tariff of course.
On mine, if the wifi is down or just not quite reaching my inverter, eco mode will not automatically charge the battery from solar.

The inverter should do what it was last setup to do if the wifi goes down.
