I figured I should come back on post a long overdue update on these. In general, I liked them. They did well on an airplane. One item I ran into was unequal battery life. After four hours on a plane, one bud would be at 55% battery, and the other would be at 12%. I didn't have the opportunity to dig...

Nice. The manual shows a parts list and some schematics. Like something from a bygone (positive) era. :) But no 50Hz mode for the 240V. The governor is adjustable and could probably be adjusted down to 50Hz. I expect you would lose a slight amount of output capacity due to the lower running RPM. Th...

All-in-all, it took me a bit over an hour to install the new meters. Definitely a success, and helpful if I ever have to run off the generator. I would like a set of smarter meters that can show power factor as well. Unfortunately, they are much larger and I'd have to figure out where to install the...

As a final test, I grabbed a hair dryer to load up the second phase. IMG_20210921_134133.jpg Everything looked good and at least reasonably accurate. I had testing both my heat gun and the hair dryer with a Kill-A-Watt. The added meters were pretty close. Time to test with real loads. I connected th...

Buttoned everything back up and time to test it with power. No magic smoke! As noted, the meters are +/-2V, so some difference between them and the built in meter is to be expected. IMG_20210921_133928_1.jpg Time to load things up. Heat guns and hair dryers are really good for basing generator testi...

With the mechanical parts done, time to address the electrical bits. First up, mount the current transformers, one on each phase. The transformers were installed on the output of the main breaker. IMG_20210921_131124_2.jpg The power to the meters, and also the voltage input are just screw terminals ...

Time for a test fit. To be fair, I had to open up on of the holes a little, vertically, to get the nice alignment.
Rear side of the mounting.

First hole drilled. I used a step bit to do the drilling. IMG_20210921_125222_1.jpg Second hole... you can see where the plastic overlay pulled and stretched when I drilled it. IMG_20210921_125420_1.jpg After a bit of clean up, it looks better. Still a little rough, but its just the overlay. The act...

Before I went drilling into the panel, I wanted to make sure there wasn't anything behind the blank spot... IMG_20210921_124849_1.jpg And there wasn't. Clear to drill... I want this to look reasonably decent, so I spent a good bit of time figuring out where the centers should be. Not the cleanest ma...

The generator has a built in meter that shows voltage, frequency, and hours. It doesn't have an ammeter. This seems like an oversight, but when I thought about it, I realize that it is more likely due to the average person not being able to interpret the display than for something like cost. The gen...
