Mitsubishi Service & Repair Forum
Hi there, I understand you're having an issue with the Mitsubishi FR-S540E-0.75K-EC unit. From what I gather, it's a 0.75kW three-phase micro inverter compatible with the FR-DU04. The problem seems to be that it's not working as expected. Let me know if you need further assistance.
