When testing out the new Phoenix Smart Inverter in the weekend I got into several issues I had not seen described in the manual. I was trying to figure out if it would handle the load of my 1200 Watt water pump (it did not, stopping after 2 minutes) or the 400 Watt heating cable (cut immediately, so…

The cable sizing is not for the load, but core saturation in the inverter.

Have you tried the Victron Toolkit app?

Pretty sure the led status for those inverters are not in the tool kit.

@LifeInGalicia Thanks for that, but may I ask where you found this? This deviates quite a bit from the manual that came with the box, which is identical to the HTML and PDF version found here . I am not quite sure if the blinking in that video would constitute fast or slow blinking or fast single pu…

Did you try to connect to the unit with VictronConnect? That should show you the error.

@M_Lange I did not. I will try that the next time I get up to the cabin. Good tip!

[image] LX: You are definitely getting DC ripple. Hmm. I know you can usually get away with thinner cables the shorter the stretch was, so I thought 35 mm2 would be OK for such a short stretch. Should be fine to just double up the cables then? As in 2x35mm2 per connection point (2x2 M8 termin…

[image] LX: core saturation Aha. New term. I just spent ten minutes not fully grokking what it is reading Quora, but the practical gist I extracted is that in transformers you need some wiggle room above what the load supplies. So maybe 35 mm2 could suffice for some given load, but I addition…

Actually double 35 works better than 70mm. Interesting thing.
So yes a perfect solution.
