    Fast shipping with quality solar cotroller.

    Very nice, quality piece of anyones solar power system. Great for expedition vehicles or home projects.

    Gets the job done for off-grid RV camping

    The ROCKSOLAR 20A handles everything my solar panels throw at it. The features of this controller is very helpful for keeping everything charging during a sudden downpour. I've only had this unit a short time, but it has exceeded my expectations.

    Worth every penny!

    High quality, Easy to use, Good diagnostics, Backlit LCD, Handles LifeP04 batteries, Recommended.

    Simple, easy and powerfull charge controller.

    If you want plug and play this is it. Hook up your panels wires, batteries wires and your rockin. No settings to go through or anything. It recognized my 24v battery right away and started charging immediately. Quality seems very good.
