Review on ๐ Renogy 500A Battery Monitor - Shunt Included, Programmable High/Low Voltage Alarm, Wide 10V-120V Range, Up to 500A, 20ft Shielded Cable, Compatible with 12V Lithium Sealed/Gel/Flooded Batteries by Frankye Sherman
Low quality. best diagnostic, test and measurement tools
Poor reliability, monitor readings become inaccurate after several months of use. The monitor is currently powered by a 100Ah battery. Resetting the capacity did not work. All wiring is reliable and the shunt is connected with high quality submarine cable. I tried isolating the monitor and tried a separate battery. The monitor will continue to show a positive input regardless of actual conditions. The monitor is currently reading a +18A charge input that is not connected to a power source. My multimeter shows the actual consumption at -0.06 amps. Renogy support was unhelpful with days between replies and ignored my warranty support request.
