The Weekender ISW System combines our largest single Solar Kit and our most popular pure sine wave inverter, for a complete RV power package. The result is an economical yet powerful way to have most of the comforts you need wherever you dry camp. Like the SOLAR EXTREME and SOLAR ELITE systems, it features all of the components that will allow convenient access to AC or solar power through your breaker panel, and the ability to charge batteries from both shore and solar power. However, the system will easily integrate with your vehicle's stock converter. The WEEKENDER ISW is easily expandable into a full-time system, with the addition of one or more expansion kits.
