Photonic Universe is an official distributor of products from Victron Energy - the globally renowned manufacturer of high quality hybrid power electronics. Victron Energy solar charge controllers have a longstanding reputation for their outstanding reliability, innovative design and superior build quality.

This Victron 150V 45A MPPT controller comes from the intelligent BlueSolar range, which uses the latest ultrafast MPPT technology to maximise energy harvest whilst maintaining optimal battery health. BlueSolar MPPT controllers uniquely boast an intelligent battery life function, along with advanced communication options for remote system monitoring.

Ultrafast MPPT Technology:

This 45A MPPT solar charge controller is designed to deliver the highest possible energy yield in the shortest amount of time. This is achieved through the use of high speed Maximum Power Point Tracking technology, which tracks the maximum power voltage point of the solar panels as it varies depending on sunlight exposure and temperature. 

This technology enables the controller to produce up to 30% greater energy yield than PWM controllers and as much as 10% more power than slower MPPT controllers. This advanced technology allows the controller to perform extremely well in low-light or cloudy conditions, as the controller consistently strives to extract the maximum available power from the solar array.

Inbuilt safety protection:

Fully equipped with an extensive range of safety features, this controller offers complete protection against potential hazards such as PV short circuit, PV reverse polarity, PV reverse current, battery reverse polarity and battery overheating - monitored via the internal temperature sensor. The controller also has self-diagnostic capability and highlights any system errors using sophisticated fault-targeting technology. These are signalled via the high intensity LED indicators.  

Advanced programming and monitoring:

The user can connect an optional MPPT Control panel (sold separately) to the controller to access a range of monitoring and programming functions. The display shows charging parameters (voltage, current, power) for the solar panel and battery as well as 30 day performance data. The user can also set the duration and voltage of each charging stage.  

Alternatively, by connecting the controller to a Victron VE Direct Bluetooth Dongle, or the VE Direct USB cable (both sold separately), the user can gain access to the VictronConnect App, which unlocks numerous possibilities for advanced programming and remote monitoring of your BlueSolar system. Once the controller is paired with the app, a wide range of additional features are made available, including:

Live data transmission: Real-time information is displayed including solar panel output, battery voltage and current (flowing into and out of the battery) as well as battery state of charge.

Detailed data logs: System activity for the past 30 days is available to view; either as in-depth daily logs or as a monthly summary. These easy-view graphics display daily energy yield, maximum recorded power and voltage, time spent in each charging stage, minimum and maximum recorded battery voltages, error records and total energy counters.

User-defined battery charging algorithm: Option to disable preset values in favour of personalised charging parameters, including user-defined absorption voltage, absorption time, float voltage, equalisation voltage and temperature compensation settings.

The VictronConnect app is compatible with most mobile devices and computers, including Android and iOS smartphones, tablets, iPads, MacBooks, Windows PCs/laptops.

Other features:

The Victron BlueSolar MPPT 150-45 model is ideal for a wide range of applications as it is resistant to extreme temperatures, high altitudes, dusty environments and marine environments. The unit enclosure is IP43 water resistant with resin encapsulation of the internal electrical components and has a PD3 pollution rating.

This solar charge controller is also compatible with a wide range of battery types, including AGM, Gel, Tubular plate and Lithium batteries.
