What are you going to plug the Sunny Web Box data logger into? It's not plugged into anything right now apart from the inverter (by the looks of the photo).
Just a little follow up, I received my first bill since I had the array installed. I'm pretty happy with the results. The bill was about 38.00 less than the previous month and I have been plugging in my PHEV Prius every evening after work. We have also had many cloudy days. Things should be great this summer.
I was very pleased by my first electric bill after having the system installed for one month. I saved approximately 38.00. Not too shabby! I am going to have some addtional work done soon. As the system stands right now it is dependent on the grid and I do not want that...a little extra wiring and parts are needed and then I can run the system independently.
Is that going to be a generator or something? I thought your batteries were charged from the solar panels anyway.
Mine is an off-grid system that charges the batteries first and then a 1kW inverter runs off the batteries. On sunny afternoons there's enough juice from the panels to supply the inverter directly (upto about 450W at the moment). The batteries just provide voltage regulation for gaps in the solar power (the odd passing cloud).
If I need to charge the batteries from the grid (in Winter) I have to manually hook up a battery charger to them. I bought an old 24V "golf cart" type charger for this. It only puts out 75W but it's enough to stop the batteries rotting in the dark months. Needless to say, I can't extract much solar power October thru to March (with almost none in November thru January). Now in May, I'm making about 7% of my total electricity from solar.
