FYI: 300A Wireless DC Voltmeter Ammeter

Postby JRHill on Mon Nov 20, 2017 11:29 am

The well "pit" is 50' away from the house and has a 4x8' insulated lid which is not fun to lift and prop up. Other than checking battery water/SGs I have no reason to get into it except during the low solar season to see voltage on the Morningstar controller. And then it might be froze shut or have a foot of snow on it, or both. I've to thought run a lead out to check the voltage but it's not happened and Lord knows I don't want to trench another conduit. Today, looking out the window at the lid I thought to do a search and found this:

Whoa, yeah, an experiment in quality but I can work with that.

300ADC? Thought some other folks might want to experiment....

Best,
Jim

Devices arrived today. Wow if this stuff came through normal channels it would cost many hundreds of dollars instead of US$25. They are really well made - whatever they can do. But the Chinese translation to English is so bad, really bad, I can only guess on operations/wireless mode.

Sometimes it's just worth a chuckle... Whether Chinese or English, technical writers have their own method of communicating.

I like the description: "...Coulomb counter..."

Good luck!
