Force Discharge Function
Posted: Sat Dec 23, 2023 2:35 pm
Hi, can anyone please help with the following?
I have the following Fox ESS equipment installed:
Fox ESS 5kWh Hybrid Inverter (H1-5.0-E ). Firmware recently updated (Master 1.63, Slave 1.02, Manager 1.70).
FOX ESS 4.3 kWh Master Battery (ECS4300H v2.0)
FOX ESS 4.3 kWh Slave Battery (ECS4300H v2.0) x2
No PV solar installed.
Octopus Go EV Tariff and Octoplus Saving Sessions.
Basically, I am trying to achieve the following:
1. Daily Charge 00:31 to 04:29 (to align with the Octopus Go EV night rate tariff).
2. Daily Discharge Option 1 - Immediate Discharge. Commence discharge to home load immediately following the charge period, from 04:30 until either MinSoC (20%) or next charge session (00:30 next day).
3. Daily Discharge Option 2 - Delayed Discharge (to take advantage of Octoplus Saving Sessions). Delay discharge to home load until a specified time, from xx:xx until MinSoC (20%) or next charge session (00:30 next day). We receive xx:xx (Octoplus Saving Session start time) with about 24hrs notice (so far this has been 16:30 or 17:00 for between 1 to 1.5hrs duration). Ideally, this needs to be a template whereby we can just alter the start time as required. This is what I have tried:
Work Model: Self-Use
User-defined:
Strategy Period
Time Period: Start Time: 16:00 End Time: 23:59
Working Mode: Force Discharge
MinSoC: 20%
FDSoC: 20%
FDpwr(w): 5000 (Not sure if this is correct?)
Items 1 and 2 have been working well since installation but when I try to implement/enable Item 3 it does not seem to work and removes all of the daily charge settings so that the battery fails to charge at the next charge period!
Any help would be greatly appreciated.
