Review on 🔋 DROK Voltage Amp Meter DC: Monitor Solar System Power with 0-300V 200A Capacity - Hall Sensor Voltmeter Ammeter Current Detector Panel by Jeff Swan

I use this to monitor my battery voltage in a small solar array. The LCD display shows the accumulated discharge when discharging and the accumulated charge when charging. I can't find a way to manually toggle between these values. Programming is not intuitive and there are options in the menu that are not explained in the manual. When setting the battery trip voltage value it doesn't save the values, when I go back to the menu item it still shows zero. An updated manual with more detailed instructions is required.
