FoxESS Community - Owners & Installers Forum

That's really helpful, Dave - you have identified the key issue (once again). I am grateful for the clarification. For the benefit of any other readers interested in this thread: yes, my generation meter sits on the supply to/from the inverter - between the AC isolator for the H1-5.0-E and the ...

Thanks, Dave - your detailed knowledge and experience are very helpful. I have left it a day or so to see if there are any other responses to my post. I can tell this is a tricky one. I too have received the same advice in the past to assess battery capacity, and I have done exactly what you ...

This forum continues to be really useful so I wonder if someone help me with this conundrum ? I have a newish system which did not do well in the cold weather since Dec but is now working more or less as expected. My problem is the apparent capacity of my 2off HV2600s is less than 3.7kWh instead of ...

Very good, Dave - that all makes sense as to how I got it wrong, and I had already concluded on the Firmware only to change if I have a clear problem.

Hopefully my experience and your advice will be of use to others.

I can report the fault is resolved and I have learnt quite a bit along the journey - much rejoicing this end ! Firstly though a big apology to Dave Foster and thanks for his persistence. In a word his first thought was correct and the "Forced charge" "Switches" were set in error. I don't know how my ...

I rebooted the system as suggested at 4:45pm - so far no change in behaviour, and still a steady 120W only feed to the house. see graph below: SoC-90s percent steady unresponsive discharge.JPG No errors on reboot except as expected at time of turn off, see below: Error Codes on shut down and start ...

Will do, Dave. I know the sequence and will try it later today when home. FYI the behaviour is perlexing in other ways. Just now there is sun and some demand from the house but it chooses to charge the battery and only slightly meet the house demand, drawing the rest from the grid ! See below: SoC ...

Thanks again, Dave - in terms of your first question, yes I believe the flows are all in the correct directions. If I understand correctly, the image you want to check (as just captured) is: Energy Flows.JPG I have never seen an error in the directions of energy flow in such views, also the currents ...

Oh yes, apologies I forgot to add the max discharge current on the inverter is set to 35A,

Many thanks, Dave - I had already double checked the settings on the inverter and the operating mode has been "self use" throughout. Both min SoC were set to 20%, but I have just changed them to 10%. I am not clear why that would influence the responses so much. Here is the Load graph for Sat. I ...

Unfortunately, my system is still unresponsive despite the lack of "forced charge" settings for 24hours. I think it is best illustrated by todays record as copied in below. During the sunshine in the middle of the day, the battery was charged but the grid was still used to deal with short peak loads ...

Thanks Dave. Having checked I find I had left a lengthy period on the battery status page to "enable forced charge" but not "enable charge from grid". I reckon I did it from Ian's video to prevent battery discharge. At the time by system was still discharging in cold weather even though it was below ...

I am hoping that someone can help me with my new Fox ESS which I have monitored closely for the last month. It is in an outbuilding so unheated – I have read with close interest the threads about cold batteries and can echo that mine has come to halt, first in the cold snap in Dec., and then in the l ...
