Common Questions
What is the maximum solar panel power I can connect?
The maximum recommended PV power depends on your battery voltage: 1000W for 12V, 2000W for 24V, 3000W for 36V, and 4000W for 48V systems. The maximum PV open circuit voltage must not exceed 150V.
How do I monitor and configure the controller?
The SmartSolar 150/70 has built-in Bluetooth, allowing you to connect wirelessly to the VictronConnect App on your smartphone, tablet, or PC for monitoring live data, viewing historical logs, and customising settings.
Is this controller suitable for Lithium batteries?
Yes, the Victron SmartSolar MPPT 150/70 is compatible with Lithium batteries, alongside AGM, Gel, and Tubular plate types. You can customise the charging algorithm via the VictronConnect App to match your specific battery requirements.
Can I use an external display with this controller?
Yes, the controller features a connection area for an optional Plug-in LCD display or an MPPT Control panel (both sold separately) for direct monitoring and programming.
Installation Notes
- Ensure adequate ventilation around the controller to prevent overheating.
- Mount the unit vertically on a non-flammable surface, away from direct sunlight or heat sources.
- Use appropriate cable gauges for solar panels and batteries to minimise voltage drop and ensure safety.
- Always connect the battery first, then the solar panels, and disconnect in reverse order.
- Refer to the manufacturer's manual for detailed wiring diagrams and safety instructions.
Before You Buy
