We are into solar tracking system. We are trying to build low cost solar tracking for field for running pumps etc.So turn tracker we are using linear actuator (24v ,6A). since there is no power supply in field these tracker will runs on batteries 12v 7ah which are connected in Series which are continuously charged by solar charge controller.
Linear actuators would not be my choice for this.
Perhaps you could post some sketches of what you have so far of the mechanism, the measures of the solar panel (length, width, weight and voltage/current), as this will have some bearing on the construction?
At what lattitude is this gonna operate?
How to build driver for linear actuator with protection
Protection against what exactly; positional, voltage, currrent or what?
Are you rigid about the linear actuators?
Is it just the driver you need, or is it the entire electronics system?
