Hello,

First of all, welcome! We're excited to have you part of the community.
The Fox site uses the same login details as the mobile app, so it's most likely that there is an error with what you're entering. Check for any spaces before or after the username or password, it must be exact and is ...

I would turn if off yes as without a com port connected you'll see a meter fault.

I would pop open the com port and double check the pins that it's been connected to vs what the manual says.

Nice write-up, thanks for sharing!

thanks for the follow up. I suspect the genny is going slightly out of G100 spec for a brief time.

G100 State3 means one of things:
1. settings > 0000 > safety settings > grid code = make sure this is set to G99 and not G97 by accident
or
2. your grid voltage is exceeding the 260v limit and your inverter is shutting down to prevent damage to your inverter and your local grid.

If you can confirm ...

Interesting SoH time/SoH breakdown. I'd recommend also recording mWh throughput if you're not recording it already as cycles won't likely be your warranty limit but the total battery throughput terms on the warranty. You should be able to see this figure in HA under the BMS value for energy.

agree, I do the same and it works great.

Morning,

Ct2 must only be connected to the ac output of the third-party solar inverter; if it is also seeing the output of the fox system, it will cause data issues in the app. Good news is that the battery charging and discharging is controlled by CT1 so shouldn't hurt the system while you get it ...

I would get your installer back, they've not setup your meter/ct correctly and clearly didn't test it before they left if the first time you charge it your system dumps it to grid.

Hey,

GridLostSet - Designed for when the H3 is operating completely off-grid with no grid connection allows you to ignore gridlost errors. Only useful if you're completely off grid with no grid connection. Leave off if you use a grid connection.
PVEPSEnable - Exactly as you say, enables pv ...

I believe this feature is called DRM in the user manual and where/how to enable this.

I assume you mean the earth cable, make sure you're using the correct screw as they are two sizes of screws in the package and people get some mixed up all the time.

Hey,

I don't believe you've got the C rating correct, more info as to how to work it out here:https://www.power-sonic.com/blog/what-is-a-battery-c-rating/

But I can save you the reading, on the EP11 battery, they recommend 13 amps DC charge/discharge or less.

Depending on your situation, you ...

They're pretty accurate as the sensor is on the inside not the outside, which might explain the difference. Try to keep it under 50c and you'll be fine.

So you're instructing your inverter to output 4.1kW, remember that this includes house loads so if you house used 2kW you would only be exporting 2kW in this 4kW example.

Can you share any details of where you think the problem is and why you believe there to be a problem?

Can you post a video or photos of what the inverter screen is doing during the export and a screenshot of your export setting configured in the mode scheduler.

Fox can email you the firmware bin file and there is a process to format a USB drive with the right folder structure for an offline update but honestly, it would be way easier to simply connect the inverter to temporary internet to update it over the cloud connection.

thanks for the update, if it keeps happening a wifi repeater might be a good idea to boost the signal to the inverter but I'd keep monitoring before investing in any additional tech.

To avoid this issue, make sure you update the manager firmware to 1.54 or later before you update the logger firmware.

1. I'm having a hard time confirming the connector type against the guide https://theecosupermarket.co.uk/identifying-fox-ess-batteries/ might be worth giving eco superstore a call as they're very helpful and offer a group discount if you tell them you're from the fox group.

2. FoxESS is ...

I would email fox again quoting your support case id and ask them for an update. Your installer should really be owning the resolution and not leaving it to you.

I'm always reluctant in updating battery firmware until I test them as they can add bms changes that limit current settings and aren't downgradable.

Hello,

You'll want to use the scheduler modes within the fox mobile app and have a force charge slot overnight and a feed-in mode slot during the day. You could also set up a force discharge in the evening if you want to discharge battery to grid and cover house loads.
This will do exactly what ...
