Modular Power Platform

Space Inventor’s Modular Power Platform (MPP) builds upon our flight-proven P4-series equipment and is scalable to suit mini- and micro-satellites from several tons down to medium-sized CubeSats. The MPP combines battery chargers (MPPT-P4), battery modules with integrated management (BAT-P4), and power distribution units (PDU-P4)—along with essential electrical power backbone-connected modules such as the Flight Preparation Panel (FPP), Kill Switches (KS), Bus Protection Unit (BPU) and passivation functionality.

Its modular architecture allows seamless scaling—supporting solar array power levels up to 4 kW—while maintaining advanced power conditioning and distribution. Each output power channel is fully protected against overcurrent and latch-up events for ultimate mission reliability.

With its inherently modular design, the MPP grows with your mission. This approach minimizes development time and risk while ensuring a heritage-proven platform that can be easily tailored to each satellite’s power requirements. Expanding battery capacity or adding power channels is as simple as adding another BAT or PDU module—no redesign required.

At its core, the Modular Power Platform (MPP) is built around a shared power backbone bus that connects all modules within the satellite power system. The backbone provides two redundant battery buses, two CAN buses, and two Platform Enable buses. Each module includes dual backbone connectors, enabling daisy-chain interconnection for compact and flexible harnessing (up to 700 W) or connection via a power aggregator (AGG) for higher power configurations  (up to 4000 W).

Beyond scalable power performance, the MPP integrates several key safety and operational subsystems to ensure dependable operation throughout all mission phases.
