The Solar PV Strings Meter (DC Strings Meter) is capable measuring 1~16 sets of strings of solar panel and sum up the generated power & accumulated total power generation. It can also measure individual power of each string, then by means of built-in programs calculation, and show every string's current power and percentages of efficiency directly on LCD display. You may also view the readings of the meter from built-in LCD by using rotation button. Further more, by means of RS-485 or ZigBee interfaces, you may use PC to communicate and collect data from meters and setup a remote monitoring system.
