Charge Time (Fox ESS H1 Inverter)
Hi,
When the installer commissioned our Solar PV system, he entered a charge time for when the batteries would be charged from the grid. This was set to 00:00-06:00.
Now that we have a new energy supplier, I have set this time (under settings > work mode > charge time) to 23:30-05:30. I have done this on the inverter itself.

When I login to the foxesscloud using a web browser, I can see the previous time setting under quick settings, but it does not reflect the newly entered time. The inverter is online.

Is there another hoop I have to go through to see the correct time setting in the cloud?

Edit: Bum! Now it has just updated when viewed on a different PC, but the enable slider is in the off position (even though it is enabled in the inverter). When I move the slider and submit, I get the message "Parameters do not meet expectations. Please reenter". Is this because the start time looks to be after the end time?

Try creating two charge periods, 23:39-23:59 and 00:00-05:29. Not being able to set periods spanning midnight was an issue until the most recent firmware, not sure if this has reached the older H1.

If you make the change in the Fox cloud it sends the data to the inverter immediately and naturally updates it's battery database so it knows what the times were without having to keep fetching them.

When you change them at the inverter panel, the times are set correctly - but, the cloud isn't refreshed immediately - I don't recall the exact refresh time but think it was every 30 minutes that it checks the inverter and it would then update what you see in the app/website.

Note the times can be set 23:30 - 05:30 perfectly fine it's only the app/website that stops you from doing that.

Yeah, that might work.
I don't think the H1-G2 is an "old" model. I believe it was only released in the UK last year.

The H1 is OK with me setting the correct period (23:30-05:30) directly using its control panel, and it worked last night.
The issue is with the foxesscloud/v2 web interface. When I enter the required times, the interface swaps them and puts 05:30 as the start and 23:30 as the finish! And I've tried with other start/finish times too. It just swaps them so that the start is before the finish.

As soon as I click OK,

Then it swaps the times and focus is set to the end time,

Thanks. Have Fox acknowledged this and are working for a fix?

There’s a long history of legacy here, on the old app it didn’t work, then it did, then it didn’t on the new app (but always will if you set on the inverter) - in all honesty as the schedules are now very much ‘day’ based i’m not sure it will be addressed any time soon, a lot of other issues to solve first I think ;) .
