Watts Up Review

The watts up meter is intended for use with rc equipment, but with tolerance of 60 volts the watts up meter can work great for small solar systems as well. The “watts up” is essentially a dc version of the popular kill a watt meter.

Watts Up vs Kill a Watt

Just like the kill-a-watt you hook the watts up meter between the source and the load. Yeah, it’s that easy. I used it recently to find out how much energy an iPad uses. Both meters are also reset when power has been disconnected. Speaking of power, one thing that the watts up Meter has over the kill a watt meter is a secondary power system for even more accuracy. This is done using a popular receiver cord that any rc hobbyists would have.

I was surprised to find that the meter had no buttons yet displayed 8 different metrics. This is done by always displaying 3 metrics and then cycling through the remaining 7.

Watts up for Solar

The most important metrics available for solar in my opinion are: peak watts (the best your panels performed in the day), watts, and watt hours. Without having to do any math you can know how much power your panels have produced and figure out how much that’s saved you in not having to buy that power from the power company.


This dc meter is going to cost you quite a bit more than it’s ac counter part. Partly because it’s not as popular (not mass produced) and I think because it’s slightly higher quality. You can get it at amazon for $50. The kill a watt sells for about half the cost.
