The SP HYBRD system is designed for high quality through manufacturability resulting in low cost. The systems are built and tested in a controlled environment. Once delivered, the unit is completely operational. The only on-site "construction" is the possible erection of the optional wind tower and/or the telecommunications equipment. Both of which can be attached to the heavy powder coated steel frame. The use of a dual-axis provides more power versus the use of a fixed mounted or seasonally adjusted type photovoltaic module racking. The use of Industrial Grade Deep-Cycle Maintenance Free Gel Batteries alleviates past problems dealing with frequent customer servicing of the batteries.
The use of the "cool-cell" battery box enhances the life of the batteries by reducing the temperature within the battery box. The water absorbs the heat generated by the batteries during the day and releases it at night while concurrently, absorbing the cooling effects of the nighttime ambient and providing chilled water for a cooling effect inside the battery box for the next day. A simple but effective means of natural convection.
The use of of a high generator combined with a dedicated large propane tank means the generator will not be overstressed and is operated at its peak for shorter periods of time maximizing its efficiency, thereby extending its service life. The projected 30-day supply of fuel mirrors regular deliveries by the Propane Company.
