Billion SG3204S
Solar DC 4 Strings Meter
The DC Strings Meter for PV Panels is suitable to be installed in small to medium-sized PV Combiner Box, which can measure the power generating capacity and accumulated total energy output for up to 4 combinations (SG3204S) PV power circuit. The DC Strings Meter can also measure instant power, voltage, and current for each loop as well as detect temperature/surge in surrounding areas. Through the electric-isolated RS-485 interface, users can remotely control and monitor the operating status of each string PV panel and analyze the collected data on the computing control system to optimize power generating performance.
