  • 110V solar panels

    Hi all !

    I have one simple question, whether there is any way how to use the old solar panels with an output voltage of 110V at home?

    panels with voltage outputs 40v or higher, are designed mostly for Grid Tie Inverters, that need 300-600VDC to run.

    The can be used for battery charging, with a MPPT charge controller that down converts the high voltage, to battery voltage.
