Abstract:
1. A solar power generating system comprising: multiple photovoltaic panels, each panel connected to its own voltage sensor that is configured to transmit voltage information to a controller via a bus; wherein each voltage sensor comprises: the bus comprises ground, power, and control wires; the ground wire is connected to the ground terminal of the multiplexer in each voltage sensor; the power wire is connected to the power terminal of the multiplexer in each voltage sensor; the control wire is connected to the control terminal of the multiplexer in each voltage sensor; the sense-out terminal of the multiplexer in each voltage sensor, except a last voltage sensor in a string, is connected to the sense-in terminal of the multiplexer in a succeeding voltage sensor in the string; and the sense-out terminal of the multiplexer in the last voltage sensor in the string is connected to a bus master.
