What are you guys that have your panels set up for an interlock/generator using to monitor watts? Not looking to spend $300 on a Sense, just something cheap, but good to measure the load.

Cheaper LCD monitors exist, and cheaper wifi units as well.

I looked into this product and the info indicated it required internet access to work. There were a couple of similar power monitors that were all the same...  You needed connectivity to get any info..



I wanted some basic info with no need for connectivity.  I ended up putting together a panel to give me total amps on each leg, voltage, and frequency.  It also has amps from the HVAC, plus amps and control (120 vs 240) over the water heater.

This is the route I would go. With these monitors you can watch each leg independently (a good idea when running a genny). Just build an enclosure. You could even build it into your generator cord so it's portable and can go anywhere (if you move or a friend needs the genny, etc).

I needed a 20A Kill-a-watt meter. Nobody makes such a thing so I rolled my own by putting a small enclosure and one of those in the middle of a 20A extension cord.

Mine is whole house, on the incoming feeder, so I needed 200 amps.  This helps in understanding different load combinations while on utility power, so we know what works on the gernator.

I also added additional contacts to the transfer switch to lock out 5 KW of emergency heat any time the generator is on. It will drop out an additional 5 KW, if the load gets to high.

Frequency on both legs is not needed.
