Genuine Victron Energy replacement circuit board for the MultiPlus-II inverter/charger. This PCBA controls the cooling fan via a 40kHz PWM signal and is designed for the MGR50 module within the MultiPlus-II platform.

Key features

• Function, generates the PWM signal that governs cooling fan speed inside the MultiPlus-II.
• Module compatibility, designed for the MGR50 module within the MultiPlus-II range.
• PWM frequency, 40kHz.
• Weight, 25g, straightforward to handle during bench repair work.
• Part reference, SKU SPR00090, GTIN 8719076060710.

Product overview

Fan control matters for thermal management in an inverter/charger. Without accurate PWM regulation the MultiPlus-II cannot modulate airflow against load and temperature, and that can lead to thermal faults or premature wear on other components. This board is a direct OEM replacement sourced from Victron Energy, supplied as a component-level spare rather than a plug-in module.

Applications

Used for component-level repair of Victron MultiPlus-II inverter/chargers, typically to replace a faulty or damaged fan PWM converter board after diagnostic testing. Suited to Victron-authorised service centres holding stock for warranty and out-of-warranty repair work.

Installation notes

This is a job for a qualified electronics or electrical technician experienced with Victron MultiPlus-II units. The MultiPlus-II carries high voltages and stores energy in its battery connections, so all AC and DC supplies must be isolated and any residual voltage discharged before the unit is opened. It should not be fitted by end users without the right training and tools.
