Sungrow systems control

I’ve hit a lot of buttons in the last two weeks and managed on two occasions to “lock the system up”.

The first occurred using iSolarCloud and the system became unresponsive to further changes to settings. The error message was something like “Waiting”. After about half an hour the system became responsive again. I believe there is some sort of time out mechanism that is built in to the iSolarCloud software to enable this.

The second occurred yesterday under mkaiser. After hitting even more buttons trying to get control I gave up and returned the system to iSolarCloud management and after a further time out period it woke up again.

Neither episode was catastrophic, but nor were they ideal. The first was exporting solar when the feed in rate was minus one cent and the power was 12 kW. The second was the opposite. I had a full battery but was drawing from the grid at peak hour.

Have others had this? Apart from not hitting the buttons are there any suggestions to avoid or manage this?

No sorry.

hmmm 20 character minimum limit

FYI. This is the video I mentioned on Thursday evening.

Using the root mean square Solcast came out on top. I have it and Forecast.Solar in my panel but have not done any testing.

How’d you go with Solcast, @zeeclor (or anyone else who has tried it)?

It looks great. I signed up for a “Hobbyist” level account and was beginning to go through the setup process, but it’s limited to two “systems”. As I have three strings at home (East/North/West), that makes things a bit awkward for me. Their own docs suggest averaging the azimuth and whatnot to stay under the two system limit, but I’m not convinced that’s going to be any more accurate than my existing approximations with Forecast.Solar.

Curious to see how anyone else in the group has got on, and whether anyone has attempted the averaging method.
