Victron SmartSolar MPPT 250/85 85A solar charge controller for solar panels up

This Victron 250V 85A MPPT controller comes from the intelligent SmartSolar range, which uses the latest ultrafast MPPT technology to maximise energy harvest whilst maintaining optimal battery health. SmartSolar MPPT controllers uniquely feature built-in Bluetooth, to allow remote system monitoring via any Bluetooth enabled device, along with a programmable relay with various signalling options.

Ultrafast MPPT Technology

This 85A 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, reverse polarity, overvoltage, overcurrent and reverse current, as well as battery overvoltage, reverse polarity and 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.

Inbuilt Bluetooth

This SmartSolar charge controller features built-in Bluetooth which allows the user to easily connect to any Bluetooth enabled device, such as a mobile phone, tablet or iPad in order to access the VictronConnect App (no additional Bluetooth dongle required). The mobile app unlocks numerous possibilities for advanced programming and remote monitoring of your Victron SmartSolar 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 also available to download as a PC version, for computers without bluetooth connectivity. If you would like to use the PC version of the app to monitor/program your SmartSolar system, this controller can be connected to your PC via a VE Direct USB cable .

VE.Can connection ports allow easy connection to Victron GX devices or other compatible solar controllers using a simple RJ45 cable.

Optional LCD display

Alternatively, this SmartSolar controller features a connection area for an optional Plug-in LCD display (sold separately). Simply remove the rubber seal on the face of the controller and plug in the removeable LCD display to access a range of monitoring and programming functions. This display shows charging parameters (voltage, current, power) for the solar panel and battery as well as 30 day performance data and any system faults. The user can also set their own charging parameters for a user-defined battery type, personalise settings for the load, charging stages and more.

Programmable relay

This solar charge controller has programmable relay contacts, which can be programmed (e.g. with a smartphone, via the app) to start a generator or to send a low battery signal which will activate an audible alarm.

Other features

The Victron SmartSolar MPPT 250/85 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 .
