Grid Tie Inverter w/Limiter and "Back Feed"
« on: December 21, 2024, 02:03:00 am »
How does this* grid tie inverter (2000w DC50-90V) monitor both phases independently in the US with split phase and only one clamp? Is it even possible to not "back feed" into the grid with this setup? Page 1 of the pdf has both methods and the images. One person claims he was able to get it working with two clamps in series, but I don't know how this does not end up with a back feed on at least one phase under ideal conditions. I can't quite comprehend the translation. Thanks for any help.

The explanation is fairly explicit, those configurations are for using the inverter to power 240V (line to line) loads only. You put the current clamp in a spur running to the line to line loads.

OK, so the phase not being monitored just matches the monitored phase.

It does because it is only monitoring 240 VAC loads which are connected between the phases.
