How our Off-Grid RSTM Packages are rated:


Three Season (3S): Three-season Wh/d ratings indicate the energy demands each package is capable of supporting for Spring, Summer, and Fall use. The 3-season ratings benefit from longer daily peak sun hours, and warmer ambient battery operating temperatures.


Four Season (4S): Four-season Wh/d ratings indicate the energy demands each package is capable of supporting. The 4-season ratings account for reduced daily peak sun hours and the colder temperatures of Winter. We always recommend keeping batteries in temperature controlled spaces above freezing.


Weekend (Wk): Weekend use implies that the PV system will be used for shorter intervals than Full-time use, and will have several days to replenish the battery bank before it is used again. As a result, the system can handle higher periodic energy demands, and has a slightly lower built-in energy reserve.


Full-time (FT): Full-time use implies that a PV system will be used on a daily basis, or for longer stretches at a time. As a result, the system is designed to handle regular day-to-day energy demands, and has a slightly higher built-in energy reserve of about +25%.
