Key Design Variables
Unlike conventional, off-the-shelf remote power systems, ForverPower is designed for your specific application. For each remote power application, the following variables are optimized:
Power Output — ForeverPower units can be designed to produce as little as ½ W/hr per day to as much as 1,000 W/hr per day.
Availability — Availiability is defined as the amount of time that the unit is able to provide energy to the load. Availabillity is usually expressed in terms of 9’s:
Number of 9’s
Availability (%)
Expected Unavailability in One Year
Two 9’s
99%
88 hours (3.7 days)
Three 9’s
99.9%
8.8 hours
Four 9’s
99.99%
0.88 hours (53 minutes)
Five 9’s
99.999%
0.088 hours (5.3 minutes)
ForeverPower can be designed to provide a specified level of availability.
Expected Service Life — ForeverPower can be designed to last ten years or longer with zero maintenance. Typically, this requires a non-battery energy storage solution. SmartSpark Energy Systems has extensive design expertise with both battery and non-battery (ultracapacitor) energy storage solutions.
Deployment Location — SmartSpark Energy Systems has developed an algorithm for properly sizing ForeverPower based on the climate in which the application will be deployed. Utilizing 30 years of historical climate and ambient sunlight data, ForeverPower can be designed to reliably power applications in almost any climate.
Size — the size of your ForeverPower unit is dependant on the variables listed above. Ultracapacitor based systems tend to be bigger and heavier than battery based systems, but have increased service life. In general, ForeverPower systems should be smaller and lighter than competitors using lead acid batteries for energy storage.
