Great for Portable Rig

This is a nice choice for a portable/DIY solar rig. It is more rugged than most and comes with sturdier connections. I also like the remote, which makes it simple to set up for different battery types. It is odd that something so simple would be so unintuitive on other cheap charge controllers. This does lack a nice display for battery or draw info. If that is okay with you, this is a good PWM controller for a small system.
