Hi guys just installed the fox system single phase on 16/1/26. I noticed that when the load is more than 3 or 4 it will withdraw from the grid. then after a while (maybe a couple of minutes or longer) grid will drop back to 20w. I wonder if this is normal? it mainly happened during higher load (say more than 3kw)
thank you
Ethan
Re: still withdraw from grid while battery has power
Can we get 4 pieces of information to assist you please...
You may have to let us know what you see for your Battery limits in your Inverter
Also to get you Export/Import power/current limits as seen in his short video
You haven't told us what Inverter you have fitted, if you have a small 4kW one, then you are going to be limited in what you can convert from your battery (DC) into power (AC)
And can you tell us what battery you have also.

I am just an end user like yourself, I wonder if that is the initial setup screen shown for a new install?
If Dave Foster views your post, hopefully he can answer what that screen is.
Having a strong Inverter like you have, it can convert 10kW and not the limited power you are seeing.
Not sure exactly what battery (should I say stack of batteries!) but if you can post the model, then we can find the charge/discharge rates. I suspect they exceed the 10kW of your Inverter if needed, which makes me suspect your Inverter has not been programmed at all, or if it has, incorrectly.
