The ICEPS2 from ISISPACE is a Satellite Electrical Power System that is available in three standard configurations with an energy storage capacity of 22.5-45.0 Wh. This off-the-shelf power system provides 3.3 V and 5V regulated buses, as well as an unregulated bus. It is equipped with hardware-based Maximum Power Point Tracking (MPPT), an integrated heater, and hardware voltage and overcurrent protection. The system incorporates wide bandgap semiconductor technologies, implementing GaN-FETs to improve solar power conversion efficiency and performance. It supports the I²C communication interface and uses a low-power MCU for control and Telemetry (TLM). The system has a mass of 5 g (2 and 4-cell battery pack) and a volume of 96 x 92 x 26.45 mm (type A - PCB and top battery). It is tailored for powering 1-3U sized platforms and LEO missions.
