REFUsol 500K - 630K

98,1% peak efficiency

With high efficiency (European efficiency of 97,6%) even the central inverters of REFUsol score points. This is because, in this device class too, we rely on our own innovative UltraEta circuit topology and quick and high-performance MPP tracking.

Innovative cooling systems

Both devices have an effective water cooling - even at 630K with a compressor. This ensures safe operation, even under extreme usage conditions.

Accessories

Ideal supplement REFUpmu
The intelligent power regulation makes it possible for the network operator to limit the power in accordance with the Medium Voltage Directive. In addition to this, the actual feed-in capacity of all connected inverters can be logged and represented via the monitoring as total power.
