System was recently installed and have had no problems to date. Recently I upgraded the Master firmware for the inverter (K10) from 1.58 to 1.60. Since then the PV output only seems to match the household draw in very sunny conditions in Self-use mode. However, when you change modes to Feed-In Priority, the PV production goes up to what you would expect for the prevalent solar conditions.
I have hard reset the whole sytem but this problem does not want to go away.
Is the firmware release a dud? If so, what can be done about it? Obviously there is no option to return to a legacy firmware version which is extrememly frustrating.
Any ideas?
Master 1.60
Slave 1.02
Manager 1.58
Have you done a full power down and up again on your system, including the battery?
The other thing to check is on the Inverter itself, the Battery power limits are not reset down to a low value.
Let us know if you do not know how to check.

I have done a full power down and up of the system with no apparent change.
Not quite sure how to check the battery power limits so any advice would be appreciated….

I just flicked through the various settings menus on my inverter it helped the PIN code was set to 0000
A video by Will to follow and check.
If you are running with a VPP company for control of your system, they could have adjusted settings, or the change of firmware can reset things.
Have now had a chance to check the settings as per the video and they seem fine. I have noticed that this issue appears to only occur in the afternoon after the batteries are over 60% charged. Internal battery temperatures are normal so it is odd that the actual PV output is not being used for charging and not being exported to the grid (except when feed-in work mode is selected).
Are you signed up to a VPP scheme, where they have control over your Inverter?
I’m not part of a VPP scheme so this is really doing my head in. If I was, then either the excess solar would still be either exported to the grid or at the very least, topping up the batteries. In self use mode it does neither while in feed in mode it shows the full PV output and puts it into the grid.
I run the same firmware here on KH7, and it runs perfect. I can only guess a setting somewhere has buggered up.
I think you need to send off the evidence to Fox to look over your settings remotely, they might see something you cannot see as an end-user level account.

What is the best way to contact as an end user? I can find Installer support but not necessarily end user support.

If you call/email then have your Inverter Serial number to hand.
From what I can tell, the email support is bad for Australia going on forum posts, so a phone call it is.
Well, I have been in contact with Foxess and they updated one lot of firmware and rolled back another with no resolution of the problem.
My inverter just clips the PV outputput as soon as the batteries reach 60% SOC. The inverter doesn't even send the excess power to the grid in self use mode and my power company has no in feed limits. I basically have a battery unit that only ever operates at maximum 65% capacity which is absolutely rubbish. In addition, I don't get credited foe any excess power I produce because the inverter won't put the excess into the grid. I am thoroughly disappointed with this setup and no one seems to have a solution for this. I will attach screen shots showing the outputs self use mode then immediate switched to feed in priority then immediately switched back to self use mode.

I can only deduce that there are settings within the software that end users don't have access to which are certainly not configured correctly for my setup. I had emailed them weeks ago and heard nothing. Finally got onto them last weekend and they reinstalled the firmware remotely with no improvement. I spent 3 hours yesterday in the phone queue which just kept timing out. I have left contact details but still no contact.
To be honest, my experience to this point has been nothing short of poor with this system and the customer service. There is no way the system should operate like this. Before the batteries, my Sungrow inverter would be supplying the house load and exporting all day, sometimes exporting as much as 9kW during the peak sunny periods (about 10kW total). This system shows nothing like that production unless the mode is set to feed in priority which is the only way you can see what the PV output actually is. All I want is my batteries full, my houseload covered and any excess production to be exported to the grid to cover my daily connection charge. That should be no problem for a system like this.

I think in the Inverter menu there is a reset choice buried in the screen somewhere, that is last resort unless support starts to respond.
