90 Watt 5 Amp 12 Volt 3 Stage Pulse Width Modulation Class B Economy RV Solar System

Our installation customers are eligible for a 10% discount on in stock replacement LED lighting bulbs.

The 90 Watt Economy RV system is a top quality entry level solar system for Class B Rv's or smal trailers.This system is a good choice for those with low 12 volt electrical demands, limited roof space, or a tight budget. The 90 watt Class B Economy system utilizes a made in USA Zamp US 90 solar panel and a Blue Sky SC30 three stage pulse width modulation solar charge controller. All components of this system are made in the USA.

The 90 Watt Class B Economy System can produce 25 to 35 amp hours per day under clear sunny skies*. The 90 Watt Class B Economy System can charge Gel, AGM, Lithium or lead acid batteries commonly used in today's RV's.

The 90 Watt Class B Economy Solar System is expandable to a total 360 watts. If in the future you find that you'd like more solar power it is possible to add a second, third or fourth 90 watt module to the existing system providing there is available roof space.

The Blue Sky  Energy Sun Charger SC30 charge controller is a flush mounted controller that we'll install in an interior cabinet wall somewhere in your RV. The black face plate blends in nicely with RV interiors. The easy to read red digital display provides battery voltage, array current (amps) and total amps produced. The SC30 has a battery equalization mode and can be programmed with the battery manufacturer's recommended charge parameters. The display can be turned off at night if the glow from the red LED's disturbs you.

Sticky Feet RV Solar Panel Mounts require 72 hours to fully bond to the RV roof. Your RV will have to sit at our shop for three days before you can pick it up.

Battery Storage Capacity: We recommend a minimum 80 amp hour (or larger) battery bank for the 90 Watt Class B Economy System. We stock a full line of Interstate RV deep cycle batteries at our Granby, Colorado shop.
