New work mode - Force Export
Dear Fox ESS Support Team,

I am a happy owner of a 42 kWh Fox ESS battery paired with my 19 kW solar array on 3-phase power in Ormeau QLD 4208, Australia.

I use the FoxCloud app daily to schedule battery discharge so I can maximise evening export credits under retailer plans such as AGL Battery Rewards (5–9 pm window).

The current “Force Discharge” work mode is the closest option, but it has a significant limitation: it only controls the battery discharge rate and does not take into account simultaneous household consumption. As a result, the actual net export to the grid is unpredictable and often falls short of my target.

Example of the issue
I want to export a total of 18.2 kW across the 5–9 pm window. My current Force Discharge schedule looks like this:
5–6 pm: 1.0 kW discharge
6–7 pm: 0.4 kW discharge
7–8 pm: 8.4 kW discharge
8–9 pm: 8.4 kW discharge
If the house is using any power during these hours (even 1–2 kW for lights, fridge, etc.), the actual export drops below 18.2 kW. There is currently no way to guarantee the exact export amount I need.

Requested new feature
Please consider adding a new work mode called “Force Export”.
In this mode the inverter would:
Let the user set a target net export rate (or total kWh over a time window)
Automatically calculate and adjust the battery discharge rate in real time to achieve exactly that export target, taking into account current household load + any solar generation

This would be a simple but powerful addition — basically “Force Discharge + automatic load compensation”.
This feature would make the Fox ESS system far more effective for customers on export-reward or time-of-use plans and would be hugely appreciated by the growing number of Australian battery owners.

I am happy to supply screenshots of my current schedules, export logs, or any other information that would help your development team.

Thank you in advance for considering this request. I look forward to hearing from you.

Kind regards,
Stuart

I believe that this is a duplicate of my request, but I like your explanation and name better :)

There was a way to do this as you will see in the comments on mine however it’s not possible now as one of the required parameters is now an installer setting again :(
Re: New work mode - Force Export
I am seeing more and more on Facebook where people are complaining that they are still drawing from the grid when in forced discharge, but they are calling that mode export thinking that the power figure set is an export to grid amount and not a fixed discharge rate from the inverter.

The trick of setting the Inverter to its maximum (or some other limit set in case for some reason they want a lower limit set) and setting the Export Limit as per Stuartmp's comment works EXACTLY as the new feature needs to work, but you can't use that now as Export Limit is an Installer setting.

I propose that there is a user set Export Target, that can't be set higher than the Export Limit so that people can still do what they are expecting, while staying within wholesaler's Export Limits in areas where there is a limit.
