Datalogger for Small Solar Systems

The use of photovoltaics for domestic purposes, in single family houses, makes it necessary to inform our users how they have aided in avoiding global warming, namely, how much solar energy they have spent. It is also of particular importance how much energy the accumulators have. A system with a microcontroller and a single-board computer is proposed for monitoring the important parameters of the small solar system. The system measures current up to 25A and voltages up to 55V in 4 channels. A SQL Server is built into a Single-board computer. Every 5 minutes the data logger sends data to a remote central server.
