I believe they have NO built-in test capability (BIT) from which they can diagnose a Protective Earth Circuit Test failure. It means the Zappi checked the Earth impedance value to...

Then it’s highly likely your Solar inverter is creating the impedance earthing issue, or as I believe you have a 3-phase system that there may be an issue of phase...

Yes difficult because getting the right conditions on the day of diagnostics eg sun, etc is near impossible. If I were investigating I’d check the labelling of the phases installed...

It’s a pleasure to help. The normal house load is usually sufficient to get a Zappi PF reading when the solar isn’t generating. So no need for an EV charge....

Well they look OK they are saying all solar outputs are currently exporting, so a useful check would be to see if your solar systems are saying the same values...

I’ve been thinking this through. I suspect there is an interaction between your Solar inverter earthing and the MyEnergi connections. It is highly likely your Zappi has been set to...

Your PF values for CT1 and 3 look far too low if you’re no longer generating any solar. But I’m confident the problem is fixed.

The problem you have is an html one, check out W3C for the correct html to open a window within a window.

You will probably find iframes are no longer supported by most new browsers

I would like to get the ESP32 or 8266 power consumption down, but to be honest it’s not a software issue that needs to be implemented or changed, the real...
