Victron Energy - 12/24/48V - BlueSolar MPPT 150/45-Tr - Non-Bluetooth - Solar Charge Controller

High-voltage MPPT charging for demanding off-grid systems

Designed for serious solar installations, this Victron MPPT controller efficiently converts higher PV voltage into usable charging current for your battery bank. The 150V PV input headroom supports longer panel strings, helping reduce cable losses and improve layout flexibility across caravans, cabins, marine builds and remote industrial sites. With 45A charging capacity and a proven Victron control platform, it’s a strong choice when you want stable charging performance across varying weather and load conditions.

Faster tracking for better harvest in changing conditions

Solar conditions rarely stay constant—passing cloud, heat and partial shading can cause rapid changes in panel output. Victron’s ultra-fast MPPT technology continuously tracks the optimum operating point, which can improve energy harvest compared with PWM controllers and slower MPPT designs (performance gains depend on conditions and array design). For installations where panels experience intermittent shading—roof racks, rigging, antennas, trees or nearby structures—the controller’s advanced maximum power point detection is built to avoid getting “stuck” on a sub-optimal point and keep charging more consistently.

High efficiency, passive cooling and real-world reliability

With a peak conversion efficiency above 98%, more of your solar energy is delivered to the battery rather than wasted as heat. The unit is fanless and uses a substantial heat sink for passive cooling, reducing moving parts and simplifying installation in enclosed electrical bays. It’s engineered to deliver strong performance at elevated ambient temperatures, with protective power derating when required to support long-term reliability in Australian conditions.

Flexible charging profiles for different battery chemistries

Charging requirements vary significantly between battery types. This controller offers a fully programmable charge algorithm plus multiple preset profiles selectable via the rotary switch, making it suitable for a wide range of lead-acid and other supported battery setups. An internal temperature sensor helps compensate absorption and float voltages, supporting healthier charging when temperatures swing between hot engine bays, coastal climates and cold inland nights.

Protection features that reduce common installation risks

Off-grid electrical systems need robust protection against wiring errors and harsh operating conditions. The controller includes electronic protections such as over-temperature management, PV short-circuit protection, PV reverse polarity protection and reverse current protection. These features help reduce the chance of damage from common faults and make commissioning and maintenance more straightforward for both DIY users and professional installers.

Monitoring options when you need visibility

For system diagnostics and performance checks, real-time data can be viewed using compatible Victron accessories such as a VE.Direct to Bluetooth Low Energy dongle or a Colour Control panel. This makes it easier to verify charge stages, troubleshoot low harvest days and confirm the controller is operating as expected.
