Well, I had it installed on the output of my multi for over a year. It does limit itself using a CT on the grid feed, and also using frequency when loadshedding.
I have two small issues with it: 1) my old bugbear - the clothes iron - when switching off, we push out current to the grid and the CT reads this, It throttles the Solis immediately, and takes up to 2 min before gradually getting back to full power. The feedback speed is totally lopsided: Pulling back current is instant, while increasing current takes 2 mins.
- When loadshedding kicks in, the CT feed of the Solis dies. And it has this weird aribitrary setting that limits its output power to whatever it was delivering at the time the grid went off. You can’t disable this setting. And this is the result:
We had a long power failure, starting at just after 8am, and the Solis limited its output to 130W. When the power came back, it jumped op to over 2kw.
