Notes from the Installation Team
We've installed several of the Morningstar SunSaver solar controllers but never a SunSaver 20. We feel that if a solar system is of the size of needing a 20 amp controller there are better options out there that include a remote display.

The SunSaver 20 controller is easy to install and the build quality is very good. The SunSaver 20 must be mounted on a vertical surface. The green charge indicating LED remains on during the day and is easy to see if the controller is installed in a darker area. The red disconnect LED illuminates if battery voltage has reached low voltage cut off. We havn't really figured out why you'd need to use the low voltage disconnect feature in a recreational vehicle application. Each of the terminal connections on the SunSaver are numbered. It is important to follow the numbering sequence during installation. Even though the SunSaver 20 is epoxy encapsulated we recommend installing it in a dry area.

What you need to Acquire
1 Automotive type ATC in-line fuse link and fuse sized for your solar system
4 - 10 Gauge ring terminals for making the solar in and the battery out connections from the SunSaver controller (6 if you use the low voltage cut off option)
2 Ring terminals for making battery connections
4 Screws for mounting the controller
