The solar panel SPSys supply controller is planned to supply a payload with 12 or 24 Volts, testing and recharging until three battery-backed systems; Its basic applications are in aerospace ambient.  The system autonomously manage the charging, the charge state and the temperature  

state  of each in function battery; by user request charging can also be execute in manual mode using external instructions, by telemetry up. To guarantee the correct amount of current many modules can be used in parallel.
