Is there anyone here knows how to install this on an inverter? I haven't been able to locate an instruction manual.

  • There's a wiring diagram on the right side. What else do you need to know?

    The wiring diagram in the top picture is different from the wiring diagram in the bottom picture. I assume the bottom one is your actual unit, and the top is just some random web picture? Is that correct? It looks like you have a manual there with installation instructions.

    Watch this video to see if it helps. Basically, the voltage connection to the meter is for voltage sensing only. The current transformer measures current on the single wire passing through the hole. Watch this video. help.ekmmetering.com/support/solutions/articles/…

You need to follow the labeling and instructions which were part of the equipment's UL, TUV, ETF etc. listing... nope, could not keep a straight face.

Seriously, the labeling and instructions that is actually on your equipment. If that's the lower picture, then the current transformer goes on 5 and 6, line to 1 and 2, and neutral to 3 and 4.

Do not daisy chain, that is don't bring "line in" into 1, and "line out" into 2, unless your diagram tells you to (such as in your first picture). In the lower pictured unit, you need to put pigtail wires on line 1 and 2, and use an appropriate 4-wire splicing device to join those pigtails to line in and line out (4 wires in total). Likewise lines 3 and 4. Note the instruction may be different for line vs neutral. That's for a reason.
