    Is Solectria PVI 4000 inverter suitable for Sanyo 205 Module Solar Panels?

    I'm designing a photovoltaic based system that uses an inverter Is Solectria PVI 4000 inverter suitable for Sanyo 205 Module Solar Panels? Or have any other combination can suggest to me? Thanks

    Design a 230Vac to 5Vdc power supply circuit using Switching regulator?

    Thanks, but can I ask will the power rating of the transformer affect the circuit work.... Example...if I use primary voltage 230Vac , Secondary voltage 10V , The power rating 30VA transformer...will the power rating affect my circuit? Can I still use 2 , 0.1uF,50V capacitor?

    Design a 230Vac to 5Vdc power supply circuit using Switching regulator?

    I can use 0.1uF, 50V capacitor, right? (with 230V,12V transformer) My friend using 230V, 28V transformer is this correct too?

    Design a 230Vac to 5Vdc power supply circuit using Switching regulator?

    Where can I find the transformer 230V and 8V....? I can't find it from element 14 or mouser electronics etc....I need the vendor part number and manufacture part number. Thanks

    Design a 230Vac to 5Vdc power supply circuit using Switching regulator?

    No,the isolation is not important for me =) I just want to design a simple schematic circuit... So is it possible to use a transformer, a rectifier and then a switching regulator(LM2596) to make this circuit? which kind of transformer and rectifier should I use? Thanks =)
