All off-grid solar power systems need an enclosure to protect the components, whether they are mobile or not. A trailer just happens to provide the required features, at a competitive cost. The ruggedized cargo trailers we use as a platform for our MS-Series provide the following benefits: 1) They provide a dry, clean, rodent-proof space that protects the system’s electrical components. 2) They are theft resistant and allow the user to move in an emergency, or move seasonally in the case of a seasonal home. 3) One of the biggest advantages is the extra space provided inside the trailer. Our past customers have used this additional space to store tools, food, sensitive electronics and emergency supplies. Some have set up mobile office spaces for jobsites, remote monitoring or surveillance.
