  • Grid tie solar and inverter sizing?

    I have 8 panels 225W 36.5V each and 5 panels 305W 45.5V each. Whats the best setup? parallel or series and should i do 225 and 305 separate string?
    Also can you point me to links for grid tie inverter to connect to 120V outlet. Greatly appreciated

    Hello Merda and welcome to Solar Panel Talk

    First off using an inverter that plugs into a 120v outlet is illegal in the US by code. So the only safe "grid tie" inverter to use would be one that has a UL listing and is approved by both your POCO and AHJ.

    Performing a DIY solar system is ok if you have the experience and knowledge of electrical circuits. You may also have to provide drawings of the installation to get a permit and approval.
