Ultra-fast Maximum Power Point Tracking (MPPT) Solar Charge Controller
The MPPT RS SmartSolar is a 48 V Solar charge controller with up to 450 VDC PV input and either 100 A, or 200 A output. It is used in on-grid and off-grid solar applications where maximum battery charging power is required.

Multiple independent MPPT tracking inputs
With multiple MPPT trackers, you can optimize your solar panel design for maximum performance for your
specific location.

Isolated PV connections for additional safety
Full galvanic isolation between PV and battery connections provide additional overall system safety.

Wide MPPT voltage range
65 – 450 VDC PV operating range, with a 120 VDC PV startup voltage.

Light weight, efficient and quiet
Thanks to high frequency technology and a new design this powerful charger weighs only 7.9 kg for the 100 A model. In addition to this it has an excellent efficiency, low standby power, and a very quiet operation.

Display and Bluetooth
The display reads battery, and controller parameters. The parameters can be accessed with a smartphone or other Bluetooth enabled device. In addition, Bluetooth can be used to set up the system and to change settings with VictronConnect.

PV Isolation resistance monitoring for peace of mind at higher voltages
The MPPT RS continuously monitors the PV array and can detect if there are faults that reduce the isolation
of the panels to unsafe levels.

VE.Can and VE.Direct port
For connection to a GX device for system monitoring, data logging, and remote firmware updates. VE.Can allows for up to 25 units to be connected together in parallel and synchronize their charging.

I/O Connections
Programmable Relay, temperature sensor, auxiliary, digital input and voltage sensor connections. The remote input can accept the Victron smallBMS, and other BMS with allow-to-charge signal

1. MPPT operating voltage range is constrained by battery voltage - PV VOC should not exceed 8 x
   battery float voltage. For example, a 52,8 V float voltage results in a maximum PV VOC of 422,4 V. See
   product manual for further information..
2. A higher short circuit current may damage the controller if PV array is connected in reverse polarity.
3. Max. 450 VOC result in appr. 360 Vmpp, therefor the maximum PV array is appr. 360 V x 20 A = 7200
   Wp.
4. The MPPT RS will test for sufficient resistive isolation between PV+ and GND, and PV- and GND. In the
   event of a resistance below the threshold, the unit will stop charging, display the error, and send the
   error signal to the GX device (if connected) for audible and email notification.
5. Programmable relay which can be set for general alarm, DC under voltage or genset start/stop function. DC rating: 4 A up to 35 VDC and 1 A up to 70 VDC
6. The MPPT RS is currently not compatible with VE.Smart Networks.
7. The Charger set-point (float and absorption) can be set to max 60 V. The output voltage at the charger terminals can be higher, due to temperature compensation as well as compensation for voltage drop over the battery cables. The maximum output current is reduced on a linear basis from full current at 60 V to 5A at 62 V. The equalization voltage can be set to max 62V, the equalization current percentage can be set to max 6%.
