KH Series Master 1.50 and Manager 1.51 Firmware
Testing for any worthwhile changes in these versions.
Please comment any findings below.

Looks like it's country restricted, as I get the error "failed Country not matched" when trying to install it in the UK.

Since my firmware was upgraded to this release I've discovered the following issues.

• Setting a force charge stopped working. I had to add a high Force Discharge Power to the time slot to get this to work. This doesn’t make sense as it handled charge power itself before (?)

• If Force Charging during the day (e.g. Free Electricity Session) the Solar was still used, and less was taken from the Grid. Now after the update, Solar seems to be disabled for the duration of the slot. Wasting Solar energy, again this worked fine before.

• Before the update, I could set a force discharge to a certain FD SoC e.g. 30% to leave enough battery for the evening until the cheap slot again. Now after the FD SoC is reached it uses Grid import for the remainder of the slot, which could get expensive.

Fox seemed to be confused as to the issues and suggested I had a 3rd Party Device changing the settings and at one point disabled mode scheduler as a fix.

Can anyone else confirm these issues?

Have you tried the Master 1.52?

Have you tried the Master 1.52?

It seems I am now a ginea pig for this new version.

Excellent, please report back

I've requested for another the upgrade to Master 1.52 on my original ticket but yet to have a reply. Not sure whether it is better to start a new request for that...

On a positive note after the upgrade to 1.5 / 1.51 I don't appear to have problems with freezing data after making changes to Mode Scheduler. Just a shame about the new issues

Got mine updated to Master 1.52, but Still NO Max SOC (Solar) setting?
Max SOC setting disappeared after firmware upgraded to 1.5

Hi Sid9

Max SoC is still there for me, but I don't think I have ever had Max SoC (Solar). Might be an older setting? Do you know what firmware you were upgraded from to 1.5? I thing I was on 1.39 previously.

[MaterialBarracuda48]

For what it is worth, no Max Solar value for my new version.

I gained a new mode called Backup, though due to testing gremlins, I have not set it.

[Sid9]

Think it was 1.43

Fox got back in touch and ran a test which verified the issue of using Grid after FD SoC Reached. But now say it is by design.

Fox Support got back in touch and ran a test on my inverter which confirmed that Grid is Used after FD SoC reached, they now say that is by design, even though it worked perfectly before.

I have set test slot for you and find it stops when it reaches FDSOC. The power stop occurs because the battery has reached the set SOC. This is how the software logic is designed: once the battery reaches the FD SOC, it will no longer discharge. If you want it to discharge, it must be outside this time period. For example, if the FD SOC is set for 5 p.m. and the battery reaches FD SOC at 4:50 p.m., the remaining ten minutes cannot be used for discharging.

What is the point of having FD SoC and a Min SoC if not going to use the Min SoC in this slot?

So rather than being able to set a schedule that will work most days I have to monitor any Charge or Discharge to make sure I am not wasting Solar, or using from Grid unnecessarily

Not impressed
