Review on 🔋 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 Christopher Yap

We'll keep you posted! I have fully calibrated the device. The power consumption seems to be about (225 W). volts right! The power consumption follows Ohm's law for output power in watts. I love how it shows the reverse charge input! For me it's worth it! The backlight flashes while charging and turns off after charging. Saves electricity. Enough settings to justify its price as long as you set it with a fudge factor until you can carefully calibrate it. If time remaining is important to you, I've found that math and dry run work best with your phone's timer. I have a 200Ah battery, the 2000W inverter says 15% load = 300W divided by 12V = 25A, 200Ah divided by 25A = less than 8 hours of run time. Observed the inverter shut down almost at the expected time. The clock initially showed an operating time of 9 hours, went up to 10 hours. So don't rely on the clock.
