Features
Hybrid Inverter/Charger
The Multi RS Solar 48/6000 is a 48V 6kVA Inverter/Charger with 450VDC 4kWp PV input.
Combination of an inverter, AC charger, and Solar MPPT
The inverter produces a perfect sine wave, and able to supply high powered appliances. It is also bi-directional, charging the battery when excess solar power or AC supply is available, or converting from the battery when it is needed.
Wide MPPT voltage range 80 – 450VDC, with a 120 VDC PV startup voltage.
Light weight, efficient and quiet
Thanks to high frequency technology and a new design this powerful inverter weighs only 11kg. In addition to this it has an excellent efficiency, low standby power, and a very quiet operation.
Display, Bluetooth and VictronConnect app
The display reads battery, inverter and solar parameters. The same parameters can be accessed with a smartphone or other Bluetooth enabled device, using the VictronConnect app.
Extendable PV capacity, both AC-coupled and DC-coupled
The integrated 4kWp PV capacity can be extended by adding Solar Chargers to the system, for example our Smart Solar Charger range, including the Smart Solar RS models. When connected in a VE.Can network, all battery charging will operate synchronously and coordinated. Alternatively, the PV capacity can be extended by installing PV Inverters, of which the output power will be automatically controlled by the integrated Frequency Shift Power Control.
Communication ports
VE.Can connection to a GX device for system monitoring, data logging, and remote firmware updates. VE.Direct connection to a GlobalLink 520 for remote data monitoring.
I/O Connections
Programmable Relay, temperature sensor and voltage sensor connections. The remote input can also be configured to accept the Victron smallBMS.
