Hi, all. I have..
2x Fox 5kWH batteries
7kW peak in PV panels; facing East
Fox 7kW inverter
I have been trying everything I know to setup a summertime regime whereby the sun comes up at 5-6am, batteries are fully charged by 7am and are thereafter just exporting all surplus to the grid. I'm on Octopus so between 4pm and 7pm I can export at peak rate. However, the sun is in the West then and my generation is low. Knowing that at 7am the following day the sun will be charging the battery again with vigour, I want to be able to set the system to force export/feed-in from 16:00 - 19:00 down to about 50% battery to get me through the night.
Despite all of my best efforts using the FOX Cloud 2.0 mobile app and/or the FOX ESS Cloud website, the system still fails to export and keeps the battery at 100% into the evening.
The settings I setup in Mode Scheduler (says 'Enable' are:
- Start = 16:00
- End = 19:00
- Work Mode = Force Discharge
- Min SOC on grid = 50%
- Max SoC = 100%
- Forced discharge cutoff soc = 50%
- MAX C power for forced discharge = 500W
It saves OK and has the enabled switch on green, but it just ignores this and when 16:00 comes around the following day it stays at 100% battery.
Can anyone advise, please? Have I got any of these settings wrong? MY installer has done a firmware update but has since gone silent.
Many thanks in advance.
Is your FDPwr really set to 500W or is that a typo ?
The FDPwr setting is the max power the inverter will discharge at but this takes into account house load so for example if your house load was 500W or greater it wouldn’t force discharge at all - you should really set that to your inverters max power 5000W
The other thing to check is that you have no schedules before this that end at 16:00 - schedules start at xx:xx:00 but end at xx:xx:59 so if you have a previous schedule that ends at 16:00(:59) it could overwrite the next schedule. i.e. you would end the previous at 15:59 and the force discharge schedule at 18:59.
