AC cables from the Micro-inverters have three conductors with different colors Hoymiles to identify the function of each conductor: Red: Live Black: Neutral Yellow-Green: Ground Pay special attention and ensure not to reverse the phase with the neutral! The installation technician is responsible for selecting a junction box with the appropriate dimensions and insulation. - Page 14 DC Cable From PV Module DC Cable From Micro Inverter Fig.8. Connect DC Cables The recommended installation need keeping the Micro-inverters underneath the photovoltaic modules, so that the Micro-inverters can operate in the shade. Direct sunlight may cause damage to the Micro-inverters. Each module must be connected to the Micro-inverters with a DC cable having a length of less than 3m.
