Hello all,
i want to make project that can monitor pv panel through arduino and communicate with matlab..so i want to know which current and voltage sensor suitable use to monitor the pv panel that produce dc output..can i use SCT-013-000V sensor to measure current??and voltage divider to measure voltage??
Thanks..
Re: Development of pv monitoring system
Look at Resources > Building Blocks, and use the search to see how others have measured the d.c. output of the PV panels. All transformers work on the principle of changing current and flux, so a C.T. will never work on direct current.
If you have only the one panel, then I suggest a small Hall-effect transducer to measure the current. You might be safe using a direct connection to measure voltage but you must be certain that the d.c. circuit from your panel is either completely isolated from any other equipment or that it and whatever you connect to shares a common connection (most likely that will be Ground). If yo cannot do this, then you must isolate the data connection to the outside world - radio is a good way to do this. Otherwise, it is very likely that a fault current will circulate that will destroy your Arduino and any computer that it is connected to.
