Hello, I'm new to this forum and have not super electonic knowledge (just little and simple).
I have a DC Source (from Solar panels) around 250 Volt DC
and want to convert it to same voltage but AC at around 55Hz (50/60)
the simplest way for me it wold be to build a squere wave generator may be with a 555 and power it with a small power source (12Volt) and connect the output to a relay DPDT and then simply use the DPDT to reverse the polarity of the 250V DC having an output of 250V AC . But I think there is be a better way (relay have long responce time) probably using Mosfet ?
The general idea is to have a DC input souce at any voltage and an output at same peek to peek voltage but AC (squere is ok ..) (Simple as possible and cheep).
If the sun is low the voltage will be less I know, .. no problem... I won't have a stable voltage .. no problem... (but I will have a stable frequency).
I do not want to use batterys for this project otherwise I would have used a normal inverter....
I appriciate any ideas, and hope do be of help in futer.
