ASPM550PANEL MICRO-INVERTER

ASPM550 · Panel micro-inverter

ASPM550 is a low-profile panel micro-inverter for factory integration into an AC photovoltaic module. The 21.5 mm profile and 1.5 kg unit weight support module-level AC conversion without a separate string inverter. Mechanical integration, electrical compatibility and the complete AC-module assembly must be confirmed for the delivered module and hardware revision.
