500V 100A 200A 500A Wireless voltage meter ammeter Solar Battery Charging coulometer capacity Power detector Tester ,Easy to Use

1, wireless transmission of data, to avoid the complex wiring between the display and detection modules to bring interference, while wiring is more simple. 2. Hall sensor is used to realize non-contact detection current without disconnecting wires, which is safe, reliable and convenient. 3, voltage, current, power, temperature, capacity, percentage of remaining capacity, running time is displayed at the same time. 4, double relay interface, you can manage charge and discharge separately. 5, with charge over voltage, discharge under voltage, charge over-current, discharge over-current protection.
