How to make from input 12VDC output 24 VAC
I found commercial product but its really expensive
I have 24VAC/400-500mA sprinkering valves
and only self powered solar garden.
Valves are not working on 24VDC they need really VAC.
Current workaround solution is 12VDC->220V->24VAC
Does somebody other and better and more effecient solution howto power 24VAC valves?
