Hello,
I have (6) 100w panels wired parallel for 18vdc /30amps approximately. This comes in and I have wired (3) 12/24vdc/30amp controllers in parallel with the PV panels. Each controller is then wired to a 12vdc battery. Simple enough. But there is an issue: I also need these batteries to provide a series output of 36vdc for an actuator motor. The series connection of the batteries is an immediate short condition. How do I protect the controllers and get the required 36vdc I need. I am using each batteries output at 12vdc for brushless motor blowers. The actuator circuit at 36vdc is also needed to maximize solar energy gain.
Kind regards,
Jim
