Question about Steffen digital brilliant

Not sure I can help you except to say that it plugs into a standard power socket. So if you can plug it in to the solar system it should work. On a more technical note don't it forget measures ac current. Hope this helps.

Nothing more to say. I bought it to measure the power consumption of my heating system.

No, it doesn't work at all. Direct current, other plugs.
