120kW 1000V MPPT DC/DC Converter for BESS | Eneruvo 120kW MPPT Controller

120kW MPPT Controller for High-Voltage BESS 120kW MPPT Controller

The ENR-MPPT-12 is a high-power MPPT DC/DC converter designed for photovoltaic integration in DC-coupled battery energy storage systems. It tracks the maximum power point of the PV array and converts solar power into a regulated DC output for charging a compatible battery DC bus.

With a rated output power of 120kW, a maximum PV array voltage of 1000V and an MPPT voltage range of 200–1000V, this external MPPT controller provides a dedicated PV-side power conversion solution for commercial and industrial solar-plus-storage applications.

Its four independent MPPT tracker units, 12 PV inputs and parallel multi-module output capability support flexible system design and expansion.
