As a preliminary step for a forthcoming solar installation connected to the grid, I want to monitor the grid and the actual power consumption. The grid quality is poor with grid outage and variable voltage. So, I want to log grid voltage, grid frequency, grid outage (i.e. voltage=0 !!!) and power consumption (let’s say average and max peak during last ¼ hour). I want to log from a couple of days up to a year. What would you suggest to do that ?
