Just had my pv system installed today. I requested the EP11 with heater which the installer said was available and I confirmed this morning that's what was being installed.

How is it supposed to work? I can't see any options in the fox app for heating and the battery temperature hasn't gone above 3°c since they switched everything on this afternoon. Is there anything I need to do or do I need to wait for any reason?

Morning,

For the heater controls to appear in the app you need the fox v2 app to be on the latest version so check the app store. You'll also need the latest inverter and battery firmware to be installed by your installer.
Once this is done you'll see the heater controls under devices > battery at the bottom of the screen near mode scheduler.

Might also be worth posting a picture of the model details sticker on the side of the battery so i/we can confirm you do have a heater model as there is a great deal of confusion about which have and don't have a heater currently.

Also worth noting that this option only appeared in the app over the last week or so and appears to be buggy on initial release so don't worry if it's not working perfectly until the next batch of fixes are released.

Looking at the feedback from Fox here: viewtopic.php?t=1127 your model number will have a H in it if it does have a heater like EP11-H

Hi Will,

Thanks for your reply.

Is there any way to check the firmware versions in the app or is this only available on installer mode?

I'll post a photo of the sticker when I get home tonight, I'm pretty sure it didn't have a -H on it though so I'm not totally convinced it's the heated one.

Don't mind too much if it's just firmware but want to make sure it's the right model.

Many thanks
Scott

You can see the firmware when you login to the cloud desktop version https://www.foxesscloud.com/

Hi Will,

I have asked the installer to check the firmware versions.

This is the sticker on the battery In the desktop version is shows version on battery master as "1.005" is that the firmware? Can't see where else the firmware version would be listed

Many Thanks
Scott

That doesn't look like a H model so no heater. Current firmware for the EP is 1.006 so nearly up to date. Your inverter firmware will also need to be the latest but if on the latest and no battery controls then it's highly likely you don't have a heater model.

Hi Will,

I've contacted the installer to see if they can get all the firmware up to date. Hopefully they can sort it out if its not the right one! Definitely need that heater in this weather!

Installer has been updating the firmware today, alas still no controls for heating so I'm assuming it's not the heated model. I'm hoping the installer will be able to sort it
