BlueSolar MPPT 150/45

MPPT (Maximum Power Point Tracking) technology is an advanced method that allows the charge controller to find and track the maximum power point of solar panels. This means it continuously optimizes voltage and current to extract the maximum possible energy from the panels, even when sunlight conditions change rapidly. The BlueSolar MPPT 150/45 uses an ultra-fast algorithm to improve energy harvest by up to 30% compared to PWM controllers and up to 10% compared to slower MPPT controllers.

The BlueSolar MPPT 150/45 charge controller delivers exceptional conversion efficiency, exceeding 98%. This high efficiency ensures that nearly all energy produced by your solar panels is converted into usable power for charging your batteries, minimizing losses.

No, the BlueSolar MPPT 150/45 is designed to operate without a cooling fan. It can maintain its full output power up to an ambient temperature of 40 °C thanks to its efficient design, which contributes to its reliability and silent operation.

The BlueSolar MPPT 150/45 includes several electronic protections to ensure system safety:

Overheat protection with power derating.PV short-circuit protection.PV polarity reversal protection.PV reverse current protection.

The BlueSolar MPPT 150/45 charge controller operates within a temperature range from -30 °C to +60 °C. It can deliver its full nominal power up to 40 °C.

The BlueSolar MPPT 150/45 features an innovative maximum power point tracking algorithm that efficiently manages partial shading conditions. In case of shading, multiple maximum power points may exist. This algorithm always identifies the optimal MPP, thus avoiding getting stuck on a less efficient local power point and maximizing energy harvest.

Yes, the BlueSolar MPPT 150/45 charge controller features a fully discharged battery recovery function. It can initiate charging even if the battery has been discharged to zero volts. Additionally, it can reconnect to a fully discharged Li-ion battery equipped with an integrated disconnection function.

The BlueSolar MPPT 150/45 has dimensions of 130 mm (height) x 186 mm (width) x 70 mm (depth) and weighs 1.25 kg.

The BlueSolar MPPT 150/45 has an IP43 protection rating for its electronic components and IP22 for the connection area.

IP43 (electronic components): Indicates protection against solid objects larger than 1 mm (such as tools) and against water splashes (rain).

IP22 (connection area): Indicates protection against solid objects larger than 12.5 mm (such as fingers) and against water droplets falling at a maximum angle of 15° from the vertical.

The BlueSolar MPPT 150/45 charge controller is compatible with a wide range of battery types. It features a fully programmable charging algorithm and eight pre-programmed algorithms selectable via a rotary switch, suitable for AGM, Gel, Lithium batteries, among others.

The BlueSolar MPPT 150/45 is compatible with 12 V, 24 V, and 48 V battery systems. A 36 V system option is also available via a software tool.

For a 12 V battery system, the maximum nominal solar panel power you can connect to the BlueSolar MPPT 150/45 is 650 W. If a higher PV power is connected, the controller will limit the input power.

For a 24 V battery system, the maximum nominal solar panel power you can connect to the BlueSolar MPPT 150/45 is 1300 W. If a higher PV power is connected, the controller will limit the input power.

For a 48 V battery system, the maximum nominal solar panel power you can connect to the BlueSolar MPPT 150/45 is 2600 W. If a higher PV power is connected, the controller will limit the input power.

The BlueSolar MPPT 150/45 controller can accept a maximum open-circuit voltage of 150 V from solar panels under the coldest conditions. The maximum start-up and operating voltage is 145 V.

The maximum short-circuit current of solar panels that the BlueSolar MPPT 150/45 can support is 50 A. It is important not to exceed this value, as a higher PV short-circuit current could damage the controller.

Yes, it is possible to use a Smart Battery Sense or a BMV-712 Smart Battery Monitor to communicate battery voltage and temperature. These devices connect via Bluetooth to one or more charge controllers, enabling precise compensation for voltage and temperature during charging.

The BlueSolar MPPT 150/45 power terminals are designed to accept cables with a maximum cross-section of 16 mm² (or AWG6). It is critical to use appropriately sized cables to ensure a safe and efficient installation.

The BlueSolar MPPT 150/45 features a fully programmable charging algorithm. You can configure it via the VictronConnect app (using the integrated Bluetooth connectivity) or select from eight pre-programmed algorithms using the rotary switch on the device. The user manual provides details on selecting and customizing these algorithms.
