I'm attaching the documentation for the RJ45 pinout and protocol information. AIMS technical support happily provided me this information when asked. My inverter is a 10,000W split-phase model, though I would think it applies to all LF models. Check with AIMS yourself if you are not sure!

Pins 3/5 = Inverter On (Normal Operation)
Pins 5/7 = Inverter On (Power Save Mode)

Cool - thanks for posting this.

It may not be obvious in the LFremote45.png - but I use pins 3-5 (close the circuit= on, open the circuit = off) to turn on/off the inverter via Midnite Solar Aux1 (relay) based on battery voltage. 3-5 and 5-7 are what the rocker switch closes on the main box or remote panel - for regular on/off and power save on/off. This works on 12,000w unit and the 2,000w unit (@ 48v) so I assume it works on all AIMs 'blue' pure sine wave inverters.

Thanks, I should have noted that as well. I occasionally hear someone doing this but they never provide details. I find it a bit odd that I'm seeing full battery voltage on pin 5, but AIMS support also did confirm that 3/5 are the correct pins to power-on.

It must be what the rocker switch on the main box (or remote panel) does - e.g. connects power (from pin 5) to either pin 3 (on) or 7 (save mode). The inverter is designed for specific battery input - so internally it would be designed to accept battery v for this.

Thanks for the youtube you just posted. I was particularly interested in how Batrium works on Charging tab... to me, Batrium is not intuitive? and so I really appreciate you showing how it works :)
