Sunscatter is the maximum power point tracking (MPPT) board used for power transformation and delivery from the solar array to the vehicle battery management system. It consists of a microcontroller actuating a DC-DC boost converter, armed with sensors to run a closed-loop feedback control consisting of both PID controllers and MPPT algorithms to optimize power delivery.
As of July 2023, we have migrated from the old Sunscatter MPPTs (sunscatter_gen1) to the new Sunscatter MPPTs (sunscatter_gen2). The major difference between these two are the user specifications and the DC-DC converter design. The Gen 2 Sunscatter boards have a higher power density and power transfer efficiency for a fraction of the cost.
