Does anyone have a solution on how to do this?
I have a 12V car battery to drive my garden lights but for some RGB LED lamps that cycle automaticly through colors i need 12V AC of 12VDC with a fair amount of rimple so the controller in the RGB LED lamp can drive it's internal clock with it.

So i need a 12V dc to 12V AC converter.

Isn't it easier to convert 220V AC to 12V AC? instead of converting DC to AC?
Or is there no 220V available?

My garden lighting is a stand alone solar system that works on a car battery which is charged by a solar panel.
Using 220V AC isn't an option
