Victron's Smart Solar MPPT RS 450|100 Isolated is a 48V solar charge controller with a 450 VDC rated PV input and a 100 A rated charge output. It has been specifically designed for use in on-grid and off-grid solar applications where maximum battery charging power is required.
It features 2 independent MPPT trackers, allowing you to optimise your solar panel design and configuration to get the maximum performance from your specific location, and can operate with a wide PV voltage range of 80 - 450 VDC (120 VDC PV startup voltage) For additional overall system safety, there is full galvanic isolation between the PV and battery connections and the controller continuously monitors the PV array to detect if there are faults that reduce the isolation of the panels to unsafe levels. The charger is lightweight (7.9kg) with excellent efficiency, low standby power and very quiet operation.
A display on the front of the unit shows important battery and controller parameters and this controller has Bluetooth communication built-in which allows you to interface with it via the VictronConnect app on your Apple/Android/Windows device. Through this app, you can configure an extensive range of functions on the controller and monitor its performance in real-time and via historical stats.
Multiple units can be synchronised in a VE.Smart Network via the VE.Can ports (25 max. in parallel). This means that all units connected to the network are linked and operating at the same stage of the charging algorithm, so they act as a single, larger charger. When the 'master' unit moves to a different stage of the charging algorithm, all units move with it.
This controller is recommended for a maximum panel power of 5800W (5.8kW) (48V system)
