EV charger not working

I had my charger fitted earlier in the winter and has been working brilliants on a schedule for the last few months charging my car up over night on cheap power. Today is the first day I have been at home with enough sun to actually try and get the solar charging mode to work but what ever I try it just does not seem to work.

First I tried just changing the settings in the app and nothing what so ever would happen. Solar, hybrid and grid all did nothing. If I tried pressing start charging it would come up with rejected error message in red.

I then went out to my car unplugged and plugged it back in and then selected grid mode and could actually press start charging. Which it did. The issue being I watched the charge rate on my dash go straight up to ~ 9.5kw before the charger went into error 18 ( output short )

I don't believe this is a short circuit as the car simply charged at a higher rate than it should. So it must have been an issue with the CP PWM set from the charger. I then power cycled the charger and tried again and it worked as expected. I was also able to drag the max charge slider around and watch the charge rate change on the cars dash.

I then tried putting it in solar mode and nothing happens even when 2+ KW are been exported to the grid. I can press start charging and it starts to charge at the rate set on the slider but this is not exactly a solar export charge mode.

I will contact support as well but I wanted to know if anybody has actually managed to get this to work.

Just to add the firmware is AC_GL1_1.07 set up in config D linked to a gen 1 5kw hybrid serial -SD2148G330 software - D0.450-A0.451

Putting all the failure issues to one side. The EV charger needs its own EM115 meter to enable solar & hybrid charging. Your inverter should have a EM115 meter, but the EV needs one as well GE, initially told me that I didn't need the EM115 meter on the. Solar / Hybrid would not work for me based on the guidance GE had provided. I then had a EM115 meter (reading the setup instructions myself) installed directly to the EV charger. Solar / Hybrid worked straight away after that. If you can have a LAN connection I would do that as well as I have found WiFi tends to be hit and miss disconnecting for no reason on the EV charger.

Lexster1979 Installation manual suggests the EM115 meter is needed for "configuration C". Presumably in "D", it's supposed to get all the info from the givenergy inverter ?

(My inference from reading the various posts on here is that "C" works rather better than "D".)

Morning, I've had the same issue with my PodPoint charger, they have just changed some settings for me so I am about to test it is working this morning. I'll let you know how I get on.

Whatever PodPoint did to our charger worked.

DD its supposed to on configuration D use the inverter, agreed. I have mine on D at the moment, but found C was just as effective.
