Ultra-fast Maximum Power Point Tracking (MPPT)
- Especially in case of a clouded sky, when light intensity is changing
continuously, a fast MPPT algorithm will improve energy harvest by up to 30% compared to PWM charge controllers and by up to
10% compared to slower MPPT controllers.
Advanced Maximum Power Point Detection in case of partial shading conditions
- If partial shading occurs, two or more
maximum power points may be present on the power-voltage curve. Conventional MPPTs tend to lock to a local MPP, which may
not be the optimum MPP. The innovative SmartSolar algorithm will always maximize energy harvest by locking to the optimum
MPP.
3.9. Frequency shift function
When external PV inverters are connected to the output of the inverter, excess solar energy is used to recharge the batteries.
Once the battery absorption voltage is reached, charge current will reduce by shifting the output frequency higher. This frequency
shift is automatic and does not require configuration on the Multi RS Solar, though the AC PV inverter may require additional
configuration. This feature is used for battery over charge protection and solar assist. It does not allow charging the battery from
an AC PV inverter to fully 100% State of Charge. To complete a full charge from solar, connect PV to the internal MPPT solar
charger, or another DC MPPT.
3.10. High peak power mode
High Peak Power
- The maximum AC output power can increase to up to a peak 9000W or 50A AC, when sufficient PV power is
also available to support the battery supply.
Isolated PV connections for additional safety
- Full galvanic isolation between PV and battery connections provide additional
overall system safety.
Temperature Protected
- Over-temperature protection and power derating when temperature is high.
3.11. Interfacing and Communications
VE.Direct port and two VE.Can ports
The Multi RS Solar only supports a data connection to a GX device (i.e Cerbo GX) via the VE.Can port, and not the VE.Direct
port. The VE.Direct port can be used to connect a GlobalLink 520 for remote data monitoring, or USB to VE.Direct dongle for
VictronConnect access on a Windows computer.
Device Display
A 4 line LCD back-lit display shows operational information including battery levels, solar yield, and system icons.
User I/O connector:
• Aux 1, 2 input
• Programmable relay
• Battery voltage sense (Vsense)
• Battery temperature sense (Tsense)
• Remote H & Remote L - Configurable
Bluetooth Smart built-in
The wireless solution to set-up, monitor and update the controller using Apple and Android smartphones, tablets or other
compatible devices.
Configuring and monitoring with VictronConnect
Configure with the VictronConnect app. Available for iOS, Android devices, as well as macOS and Windows computers. A
VE.Direct to USB accessory is required for Windows systems; enter VictronConnect in the search box on our website and see the
VictronConnect download page for details.
3.12. Battery charger
The batteries can be charged by solar energy using the built-in MPPT solar controller, a compatible AC supply connected to the
AC input, or an AC PV grid inverter connected to the AC output. The built-in MPPT has a power limit of 4000W. So the maximum
