FoxESS Community - Owners & Installers Forum

Hi there.

I moved into a house with Foxess system already installed last year.

Through summer it was great - battery rarely running out of power when it was sunny, but during this winter, especially when wfh, we can be depleting the battery (to min soc 10%) before the peak tariff with Octopus at 4pm, meaning we've paying full whack from the grid for that evening period.

I've read as many posts on the forum as possible about using the scheduler - watched the videos posted on the forum, etc, but haven't been able to find the answer to my query, which is:

Which scheduler settings do I need to use so that I can get the following:

02:00-05:00 = Charge from grid
05:00-16:00 = Self-use (but batteries only being used up to say 50% - so that we keep enough battery to run through 16:00-19:00 peak period. meaning if we did use a lot before 16:00, we'd go to grid usage)
16:00-19:00 = Self-use battery up to 10%soc
(Rest of the time = self use)

I tried to schedule the following periods but may have overcomplicated matters as I got an error code of '40257 parameters don't meet expectations'


Any help really appreciated

Our system:
Inverter H1-5.0E
firmware:
master: 1.70
slave: 1.02
manager: 1.78

12 x 380w panels

Batteries
3xHV2600 (nominal 7.68kWh)
version BM 1.020

I would just erase those and start afresh, as you don't need as many.

1st 02:00 to 04:59 A force charge, and make sure to put 5000W if you have 5kW Inverter.
2nd 05:00 to 15:59 Self-use, with Min SoC 50%, Max 100% and FD SoC at 50% and put again 5000W
3rd 16:00 to 19:00 (or 23:59 it doesn't matter) and set your 3 values to 10%, and put 5000W as power

Then check your graphs (swipe right to left, and power graph at the bottom) tomorrow after a full day, to check it responds as expected.

Great thank you.
Have just inputted those and it saved successfully which is a good first start

Will see what happens tomorrow

Thanks

Look forward to hearing results tomorrow evening hopefully.
