3.5 Inverter installation

Reserve enough clearance around the inverter to ensure sufficient space for heat dissipation.

Installation spacing

In case of multiple inverters, reserve specific clearance between the inverters.

When installing inverters back-to-back, the distance between every two inverters should be at least 600 mm.

≥600mm

≥450mm

≥300mm

≥600mm
