Victron Energy BlueSolar MPPT Solar Charge Controller 75V 10A — 12/24V, high-efficiency MPPT for boats & vans

The Victron Energy BlueSolar MPPT 75V 10A is a high-efficiency solar charge controller that optimizes panel output and safely charges 12V or 24V battery banks.

Designed for small to midsize off-grid and mobile solar setups, the BlueSolar MPPT brings fast maximum power point tracking and advanced charging algorithms to improve energy harvest and battery life. It accepts up to 75V from the solar array and delivers up to 10A to 12V or 24V batteries, making it a compact, reliable choice for boats, campervans, tiny homes, and remote cabins.

How does the BlueSolar MPPT increase solar energy harvest?

The controller uses MPPT (Maximum Power Point Tracking) to continuously find the best operating voltage for your solar panels, so they deliver the highest possible power under changing conditions like cloud cover or partial shading.

• Rapid tracking adjusts to panel voltage changes for peak output.
• Works with panels up to 75V input for flexible array designs.
• Reduces energy losses compared with PWM controllers, especially when panel voltage exceeds battery voltage.

What battery types and voltages does it support?

The BlueSolar MPPT is compatible with 12V and 24V battery systems and supports common lead‑acid and lithium chemistries when configured correctly, providing multi-stage charging to help maintain battery health.

• Automatic detection and regulation for 12V/24V systems.
• Programmable charge profiles to match battery specifications.
• Smart charge algorithms to reduce overcharging and extend service life.

Can I monitor and control the controller remotely?

Yes—remote monitoring and configuration are available via VictronConnect, but note this BlueSolar model requires a separately sold Bluetooth dongle to enable wireless connection.

• Pair with VictronConnect to view real-time data and settings.
• Bluetooth dongle sold separately for wireless access.
• Local LED indicators provide basic status without a smartphone.

How does installation and wiring flexibility look?

The compact enclosure and clear terminal layout make the unit straightforward to fit into small electrical compartments, while its 75V PV input allows for longer cable runs or higher-voltage panel strings in constrained systems.

• Compact form factor fits tight spaces on boats and vehicles.
• High 75V PV input for flexible panel placement and array design.
• Clear labeling of PV, battery, and load terminals simplifies wiring.

Who is this for: The Victron Energy BlueSolar MPPT 75V 10A is best suited to DIY solar builders and small-system installers who need a dependable, efficient charge controller for 12V or 24V battery banks. It fits applications such as campervans, boats, small cabins, and backup power setups where maximizing output from limited panel area matters and remote monitoring is desirable when paired with an optional Bluetooth dongle. Choose this unit when you want proven MPPT performance from a compact controller without built-in Bluetooth—upgradeable via Victron accessories if you later want wireless monitoring.
