SmartSolar MPPT 250/85-MC4 VE.Can

MPPT (Maximum Power Point Tracking) technology is an advanced method for tracking the maximum power point that allows the solar charge controller to maximize energy harvesting from your solar panels. The SmartSolar MPPT 250/85-MC4 VE.Can uses an ultra-fast MPPT algorithm that continuously optimizes the power extracted from the panels, even under variable weather conditions or partial shading, to charge your batteries as efficiently as possible.

The SmartSolar MPPT 250/85-MC4 VE.Can is designed to manage solar panels with an open-circuit voltage (Voc) up to 250V. It is critical not to exceed this voltage to avoid damaging the charge controller.

This charge controller can supply a maximum charging current of 85A to your battery bank. This makes it suitable for high-capacity solar systems.

The SmartSolar MPPT 250/85-MC4 VE.Can is compatible with a wide range of battery chemistries, including lead-acid batteries (gel, AGM, flooded) and lithium batteries (LiFePO4). Its adaptive charging algorithm is fully programmable to meet the specific requirements of your battery type.

Yes, the SmartSolar MPPT 250/85-MC4 VE.Can automatically detects and charges battery banks of 12V, 24V or 48V. For 36V systems, detection and configuration must be done manually.

The controller is equipped with multiple protections to ensure the safety of your system and the product itself. These include:

Protection against PV polarity reversalProtection against output short-circuitsProtection against overheating with automatic power reduction

Yes, the SmartSolar MPPT 250/85-MC4 VE.Can can recharge deeply discharged batteries. It can operate with a battery voltage down to 0 V, provided the battery cells are not damaged.

The controller offers several advanced connectivity options:

Integrated Bluetooth Smart: Enables configuration and real-time monitoring via the VictronConnect app on your smartphone or tablet.VE.Can ports: For daisy-chaining multiple controllers and transmitting data to a Victron GX monitoring device.Victron Remote Management (VRM) Portal: For full visibility and remote control of your system over the internet by connecting the controller to a GX device.VE.Direct port: For connection to other Victron devices or a PC via a VE.Direct to USB interface.

Yes, using the VE.Can ports, you can daisy-chain up to 25 additional VE.Can SmartSolar chargers. This enables synchronized charging stages and centralized management of your large-scale solar system.

The SmartSolar MPPT 250/85-MC4 VE.Can is equipped with MC4 connectors for easy and secure connection of your solar panels. MC4 connectors are an industry standard for photovoltaic installations.

For optimal installation, the controller must be mounted vertically on a non-flammable surface, with sufficient space above and below to allow proper airflow and heat dissipation. It is recommended to place it in a dry location protected from direct weather exposure. Connections must be made in accordance with the user manual to ensure safety and performance.

The maximum power of solar panels you can connect depends on the voltage of your battery bank:

For a 12V system: up to 1200W
For a 24V system: up to 2400W
For a 36V system: up to 3600W
For a 48V system: up to 4900W
It is important not to exceed these values to ensure proper operation and longevity of the charge controller.

The multi-stage adaptive charging algorithm automatically adjusts the charging process based on the battery's state. It typically includes the following phases:

Bulk (Bulk charge): Charges the battery at maximum current until it reaches a specific voltage.
Absorption: Maintains a constant voltage to ensure a complete and balanced charge.
Float (Float charge): Reduces voltage to maintain the battery at full charge without overcharging.
Storage: A slightly lower voltage for extended periods of non-use to minimize battery aging.
This algorithm extends battery lifespan and optimizes performance.

Victron Energy products are generally designed for demanding environments, including marine applications. While the IP43 protection rating for electronic components and IP22 for connections provide good resistance to splashes and dust, it is still recommended to install the controller in a location protected from direct moisture, salt spray, and extreme temperatures to maximize its lifespan and performance in a marine environment.

The SmartSolar MPPT 250/85-MC4 VE.Can offers high MPPT conversion efficiency, reaching up to 98%. This means it optimizes energy recovery from your solar panels with minimal loss.

The controller can be connected to a Victron GX monitoring device (such as a Cerbo GX) via the VE.Can port or the VE.Direct port. This connection allows the GX device to collect data from the controller, display it locally, and transmit it to the Victron Remote Management (VRM) portal for complete remote monitoring of your system.

The SmartSolar MPPT 250/85-MC4 VE.Can is designed with passive cooling (fanless) for most operating conditions. In case of overheating, it features built-in protection that automatically reduces output power to prevent damage. It is essential to ensure adequate ventilation around the device during installation to aid heat dissipation.
