Carevas 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 Tra

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 from DC 5V to 90V supports two-wire or three-wire system. Adopts Hall sensor for non- measurement and provides with reverse polarity protection to burning. STN LCD display with backlit clearly shows the value even under the direct sunlight. indicator flashes to tell the state of low battery and charging and alerts you the state of overvoltage undervoltage and overcurrent. More functions - backlight clearing(reset) and data autosave when power down. Widely applied on solar panelssystem 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.
