Regulatory Victron SmartSolar MPPT 250/85

Victron SmartSolar MPPT 250/85: High voltage 245V input, Bluetooth monitoring and professional power for self-consumption

Ensuring maximum efficiency and stability on an isolated or residential solar plant depends directly on the controller's ability to manage large chains of . The regulator Victron SmartSolar MPPT 250/85 Represents the high range of engineering Victron Energy, offering an ideal solution for projects that require working with raised voltages in the photovoltaic field. When processing the direct current, this robust equipment not only accelerates the load of accumulators, but acts as an intelligent shield that maximizes the overall efficiency of the installation.

Ultra-fast tracking and flexibility in high voltage strings

The main virtue of this device against conventional regulators lies in the speed of calculation of its processor. In scenarios with partial shading or rapid variations of irradiance, its technology Ultrafast tracking MPPT Locate the optimal work point in milliseconds, rescuing daily energy volume much higher than other market controllers.

Its most disruptive technical characteristic is its ability to support up 245V maximum tension in open circuit (VOC). This allows installers to design series (stringsof Much longer, drastically reducing losses due to voltage drop in wiring, cheapering the costs of protections and simplifying connections on the roof. The device has Automatic voltage detection To work autonomously with 12V, 24V or 48V batteries, adapting its recommended power capacity from 1200W A 12V, 2400W to 24V, until reaching an upper limit of 4900W A 48V. If the plates generate a surplus of watts on extremely cold days, the internal software self-limiting the output to safeguard the circuit. If you need to set your photovoltaic modules impeccably on flat or tilted covers, we invite you to consolidate your installation using our Aluminum high strength.

Wireless connectivity series and maximum electric safety

Unlike classic industrial controllers that require mandatory external screens, the series Smartsolar It has a factory integrated a chip Smart Bluetooth High Efficiency. This allows users and technicians to link the regulator directly with a smartphone through the VictronConnect app. From the application you can customize the load phases according to the accurate chemistry of the accumulators (including advanced curves for LifePO4 lithium batteries), visualize historical daily production and monitor the state in real time. If you are planning a residential project focused on direct injection to the electrical network without physical storage to reduce your monthly bill, you can check the appropriate options in our menu of inverters networking.

The safety of the SmartSolar MPPT 250/85 is shielded through strict electronic barriers. Admits a Maximum short circuit intensity of 70A at photovoltaic entrance, and is available in Two types of physical entry: Large-section screw terminals (TR model) or MC4 quick connectors for an agile installation. The loading process is activated every morning automatedly when the tension of the solar 5V is located above the battery voltage, maintaining the active electrical flow when requiring a minimum differential of at least 1V for the rest of the sun's hours.

Frequently asked questions

1. What advantages do you provide that this regulator accept up to 245V solar input?

Allows you to connect a greater number of Solar in series within the same chain or string. When working at such a high voltage, the current (amperage) that travels through the cables is lower, which reduces heat losses, it allows to use finer cable sections and optimizes the overall performance of the installation.

2. What happens if the field of Solar exceeds the power in watts recommended to 48V?

The regulator incorporates active software protection. If you connect more than the 4900w Recommended on a 48V bank, the equipment will not suffer damage or burn; It will simply limit automatically the output power to its maximum nominal current of 85a, Protecting your internal components.

3. Why is it mandatory to strictly respect the 70th short-circuit intensity limit (ISC)?

The 70a They represent the maximum physical tolerance that admit the entry terminals and the regulator's electronic tracks. If a configuration is made with too many chains in parallel that exceeds this amperage, an accidental short in the plates could derive a destructive stream towards the regulator, causing an irreparable fault.

4. How does the winter temperature influence when calculating the maximum voltage 245V limit?

The Solar increases its open circuit voltage (VOC) As you lower the ambient temperature. When designing the string, the installer must calculate the sum of the plates voltage considering the coldest day of the year in the area, making sure that total sum never reaches nor does it exceed the 245v not to destroy the electronics of the team.

5. Is this 85A regulator compatible with current lithium batteries?

Yes, it is completely compatible. Thanks to Bluetooth integrated, you can connect wirelessly from your smartphone with the VICTRONCONNECT app, access the regulator settings and select the specific profile for lithium batteries (Lifepo4or manually enter the exact voltage parameters indicated by the battery manufacturer.
