Hi people,
The plot thickens on the gate opener. I have tracked down a manual for the satellite actuator and it is 36v. So now we are talking opening speed.
Problem is how do I get 36vdc at around 4A out of a 12v battery? I have to solar charge the battery.
One thought is to use 3 smaller 12v batteries in series each with their own dashboard-style solar charger. Those dashboard chargers are rated at 5W and they have a non-discharge diode which would prevent back flow into the panel. Would that work????
Any thoughts on this or other alternatives? A dc-dc converter would be costly for 36v @ 4A continuous I am guessing.
I did a surplus search and found one 12v-36v converter for $125, way outta my league for this project. Admittedly it was rated at about 30A or more.
