Device that Data Logs Generator Output?

Device that Data Logs Generator Output?

Device that Data Logs Generator Output?

I am hoping someone here might have recommendations for a product that can data log volts, amps, and frequency coming off an AC generator. Ideally, the product would be able to connect to local wifi and transmit the data in real time. If no such product exists then an alternative would be to data log on site and download the data periodically in person.

I thought Fluke Connect would be a good solution, but it seems as though there needs to be a mobile device present near the fluke device at all times. There are some Fluke multimeters that can data log, but wanted to get this communities opinion on possible alternatives.

Any help is appreciated.

RE: Device that Data Logs Generator Output?

What genset controller is fitted, that device may have an upgrade available to perform what you want. Alternatively try Comap intellisys https://www.comap-control.com/products/controllers...

this has web based monitoring and ethernet data port. i think they offer remote monitoring software.

other controller manufacturers offer similar devices.

Best to look for local support

RE: Device that Data Logs Generator Output?

Thanks Hoxton and Tugboat. Both of those solutions might be a little more than I need. It does not seem like either one has wifi built in, but I could be wrong.

Another forum suggested this: https://www.victronenergy.com/panel-systems-remote...

RE: Device that Data Logs Generator Output?

When you mentioned Fluke I assumed you had an industrial level budget. Victron is consumer grade equipment.

Something like this might work https://aemc.com/products/power-analyzers/power-pe...

Perhaps if you advise why you're looking at capturing data off the generator as well?
Is it a pilot product that you're doing validation on, or is it an existing piece of equipment with issues?
Some of us may have ideas on alternate means of solving whatever problem you might have.

I have installed and setup a number of these meters on several standby generators, as well as several battery systems and a couple mid-size industrial solar projects,

They have a reasonable cost, install and setup is pretty straight forward, data is easier to deal with compared to many other manufacturer's power meters (at least in my experience) and so far as I know after more than 100 meters installed in the last 4 year, no failures I'm aware of.

The web server is liked by many of my customers. The wireless module and web server is an optional module, https://www.accuenergy.com/products/axm-web2-multi...

Hope that helps,

RE: Device that Data Logs Generator Output?

Thanks Catserveng. That looks like a great solution.

RE: Device that Data Logs Generator Output?

When I first started dealing with them I was cautious, seemed to be too cheap to do all they said the meters would do, but overall their performance has exceeded many of the larger manufacturer's from what I have seen, and their product support has been very good to date.

Good luck on your project.


RE: Device that Data Logs Generator Output?

Catserveng - I received a quote from Accuenergy, unfortunately their specs aren't quite what I need. The lowest measurable frequency is 45Hz. The generator I am wanting to monitor is variable speed depending on the prime mover. Do you have any other recommendations that I could look into?

RE: Device that Data Logs Generator Output?

I can't imagine a generator that operates less than 45Hz. Variations in speed are typically 2-3 Hz from the fundamental frequency (50 or 60Hz, depending on where you are). But maybe I'm misunderstanding the application.

Regardless, I've found the Phoenix Contact power meters (EEM series) were a good value permanent power monitoring solution. I like them because they store the data onboard that you can retrieve via a local webserver.


RE: Device that Data Logs Generator Output?

It actually doesn’t take much imagination. I don’t know what the OP is doing but there are lots of wind turbines that generate at whatever frequency suits the moment and the output goes through power conversion electronics and comes out at the local power system frequency.

RE: Device that Data Logs Generator Output?

All standard data loggers have a frequency band of +/- 5 Hz of 50/60 Hz.

For your variable frequency (and possibly variable voltage) data logging, you might want to try the data loggers used in VFD's.

Drive gurus in this forum are great sources of valuable knowledge.
