Currently running 1.29 firmware - and yes I am a UK user as BJ suggests ;)

Here's the error See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ************** Exception Text ************** System.ArgumentNullException: Value cannot be null. Parameter name: value at...

I only have a Powerwall 2. Was interested in seeing what you'd done in that regard.

Yeh

The app crashes for me after login. What are the runtime prereqs?

Anyone noticed loud fan noise for 30 mins with 1.22.1 after setting a new backup reserve percent? This happens now for me regardless of temperature or power state after a call to sitemaster/run

Phone them up and ask them to do a remote reboot of your gateway?

Already responded to this earlier. I'll paste again for your convenience ;) It will be hard to know this for sure until a similar time of the year in 2019, but I would estimate this to be somewhere between 40-60%.

Agreed - fascinating stuff!

Yeah I guess the panels are much hotter than 44° in the sunshine. A 25% power loss probably puts them in the 90-100°C range!

Interesting - so it's probably temperature that's limiting production to 5kW when it's 28°C ambient (hot for the UK!) and the sun's been baking the panels all morning. I knew temperature affected things, but had no idea it was to the tune of 25%+ Thanks for the info guys :)

Yes that's right - I have one 3.54kW system on my East roof and another identical system on the West. My roofs are at a 32° pitch and are facing 121° and 301°. They're not flat.

I realise my system isn't typical, but my installer basically did what I asked. I thought there would be a fairly obvious switch from the East to West roof in terms of production, but in practice ambient and scattered light can still produce a decent amount of energy when in shade. This is...

I've done a similar thing, if not slightly less elaborate. ;) I also use PW2 API data to allow me to vary the charge rate of my EV to match my excess. Losing access to this telemetry would mess up several significant investments. :(

Losing this functionality would be devastating - I rely on the telemetry from my PW2 to automate 3 different systems! I've been on v1.20.0 for about 4 or 5 days now and still haven't lost control of monitoring functionality. Finger crossed. Please get tweeting so we can make or objection...

My experience with inverter clipping is a similar story. I had two 3.54kW systems installed on my East/West facing roofs back in February. The installer recommended and installed a SolarEdge 3.68kW inverter, as this matched the standard grid export limits for the UK. It was pretty obvious even...
