DC 5V~90V Digital Voltmeter Ammeter Gauge Battery Capacity Electric Energy Monitor 5-in-1 Voltage Amp Power Watt-Hour Meter LCD Display Coulometer with Hall Sensor for Solar Panel System Travel Trailer RV

Features:
Used to monitor the real-time current, voltage, power, battery capacity, residual capacity(Ah), and cumulative total watts.
Precisely measure the percentage and ampere-hour of battery capacity, DC birectional current(+/-), DC power(+/-), DC voltage, and DC cumulative energy total(+/-). 
Wide supply voltage range from DC 5V to 90V, supports two-wire or three-wire system.
Adopts Hall sensor for non-contact measurement, and provides with reverse polarity protection to prevent burning.
STN LCD display with backlit clearly shows the value even under the direct sunlight.
LED indicator flashes to tell the state of low battery and charging, and alerts you the state of overvoltage, undervoltage, and overcurrent.
More functions – backlight, zero clearing(reset), and data autosave when power down.
Widely applied on solar panels/system, battery bank, travel trailer, automobile, RV, model train, etc.

Note:
*Please note that the unit is NOT watertight.
*Applied load should not exceed the rate power.
