320kW 1500V MPPT DC/DC Converter for BESS | Eneruvo 320kW MPPT Controller

320kW MPPT Controller 1500V DC/DC Converter for DC-Coupled Energy Storage

The ENR-MPPT-24 is a high-power, high-voltage MPPT DC/DC converter designed for photovoltaic integration with compatible battery energy storage systems. It tracks the maximum power point of the PV array and converts PV power into a regulated DC output for charging the battery DC bus in a DC-coupled energy storage architecture.

With a rated output power of 320kW, a maximum PV array voltage of 1500V and an MPPT operating range of 500–1460V, this external MPPT controller is designed for high-voltage, high-power solar-plus-storage applications.

The ENR-MPPT-24 features 24 PV inputs and six MPPT tracker units. Its output voltage range of 950–1500V supports integration with compatible high-voltage battery DC buses, subject to the battery system’s voltage limits and electrical compatibility.

Applications

The ENR-MPPT-24 is designed for compatible high-voltage DC-coupled solar and battery energy storage systems requiring high-power PV-side MPPT control and DC/DC conversion.

Typical applications include:

• High-voltage battery energy storage systems (BESS).
• DC-coupled solar-plus-storage installations.
• High-power PV-to-battery DC conversion.
• Commercial, industrial and larger-scale energy storage projects.
• Modular energy storage systems requiring high-power converter integration.

High-Voltage MPPT Conversion for Large Energy Storage Systems

For high-power DC-coupled energy storage, the MPPT DC/DC converter must be selected according to the PV array voltage, MPPT operating range, battery-side DC voltage, rated current and system protection requirements.

The ENR-MPPT-24 combines 320kW rated output power, six MPPT tracker units, a PV input voltage of up to 1500V and a battery-side output voltage range of 950–1500V. Its IP66 enclosure and smart air cooling support deployment in demanding operating environments.

The converter can be incorporated into a compatible energy storage architecture to provide dedicated PV maximum power point tracking and DC charging. System integration should verify the battery voltage window, maximum withstand voltage, current limits, protection coordination and communication requirements.
