I need an Ammeter to control the charge ( from Photovoltaic Module or Alternator or Battery Charger) or discharge ( to the various Loads ) of the main battery of my boat.
Model ” DROK® Voltmeter Ammeter Volt Amp Multimeter DC 4.5-30V 100A Voltage Currenr Monitor Ampere Voltage Combo Testing Meter Gauge V/A Panel Meter for Car Auto Motocycle Battery Power Indoor Outdoor Red/Blue Dual LED Display with Current Shunt” is Suitable?
This model is able to distinguish negative to positive current ( i.e. charge to discharge)? or you suggest an other item.
Do you have also advices for the wiring ( apart the wiring diagram on the brochure).
