[RE-wrenches] Voltage discrepancy

[Darryl Thayer]

Any way she can get a real voltmeter?  the MX60 has voltage calibration, so does the FX  it sounds like something is over charging, perhaps the generator run?   additonal details on battery bank size, array size and typical load.

Hello Wrenches, 

I just got off the phone with an off grid system owner who has a voltage discrepancy showing between the reading on her MX-60 and both her Mate and Trimetric meter.  The MX-60 shows 28.8 V and the Trimetric and the Mate both show around 25 volts.  The batteries are using a tremendous amount of water.

Has anyone seen this scenario before?  Do you think the MX-60 is bad? 

Thanks,
