Efficient Solar Panels with eIQ Energy’s Parallux vBoost 250

250-watt DC-to-DC converter module

Designed for use with lower-voltage panels (20 to 50 volts), the vBoost 250 mounts directly on the PV panel rail, connecting with an MC3 or optional MC4 connector. Power and data are carried on a single wire pair with optional MC4 connector.
