Our Power API

Drawing on the success of APIs that have made iPhone and Android a platform for app development, Fenix has created a “Power API” to give inventors and entrepreneurs the tools you need to create and sell innovative new products using the ReadySet as an energy platform.  By publishing a Power API and building a Developer Platform, we hope to empower you to create the micro-wind turbines, vaccine refrigerators, and next generation products that we cannot even imagine yet.

Developer Platform

We’ve teamed up with our friends at Instructables.com to create a ReadySet Group where innovators can work together to create applications as well as post questions at different stages of development.

ReadySet Technical Specifications

Charge Input Specification

Solar
Solar Array Voltage: 16-60V
Solar Array Power: 5-75W (up to 5 of the Fenix solar panels in parallel)
Solar Power Algorithm: Maximum Power Point Tracking (MPPT)
Note: Due the characteristics of the battery, the charge rate is limited to a max charge power of 30W regardless of available solar power. If energy is being drawn from the power ports while charging, the ReadySet can convert up to an additional 30W of solar energy and provide it directly to the outputs (bypassing the battery) for a total of 60W of solar energy conversion.


AC-DC Electric Wall Adapter

Normal Power Brick Voltage: 16-19V
Normal Charge Power: 20W
Normal Charge Current: Charging is constant power, current will vary based on input voltage

High Power Brick Voltage: 20-60V
High Charge Power: 30W
High Charge Current: Charging is constant power, current will vary based on input voltage


Charge Source Qualification

Once voltage is detected on the charge input, the ReadySet qualifies the input to determine what type of source has been attached. Voltage is measured and current is pulled from the input source to determine its stability and characteristics. If measured characteristic match those of a solar array, MPPT is enabled. If not, constant power charging is assumed and charge power is set based on the open circuit DC brick voltage (per previously enumerated AC-DC brick supply specs). The brick included with the ReadySet Kit is rated at 18V, 1.3A (23.4W).

Charge Output Specification

CLA Output
Voltage Range: 11.5V – 15VDC (nominal 12VDC)
Current Limit: 6A±0.25A combined (approximately 72W@12VDC)

USB Output
Voltage Range: 4.75V – 5.25VDC (nominal 5VDC)
Current Limit:  2A±0.1A combined (approximately 10W@5VDC)
Note: Upper USB port is configured to signal 1A charge capability for Apple devices

Battery Specification

Nominal Voltage: 12V
Capacity: 9Ah
Chemistry: Valve-Regulated Lead-Acid
Max Charge Power: 30W
Usable Energy: 54Wh
Note: Usable energy is intentionally less than the full battery capacity to protect the battery from deep discharge and extend the lifetime of the battery.
