The protection box is designed to cater for the unique dual MPPT layout of the three phase Sunsynk 12kW hybrid inverter. The box is sub-divided into two parts:
- 2input, 2output ports with a 32A isolator and type I_II SPDs – this connects to the first MPPT
- 1input, 1output ports with a 16A isolar and type I_II SPDs – this connects to the second MPPT
