DC-Coupled Expertise

Intelligent PV integration

High solar utilisation and optimised energy storage. DC coupling puts solar PV, batteries, MPPT control and power conversion into one efficient energy system.

How DC coupling works

PV power goes through a DC-DC converter straight into the battery bus. Only the energy sent to loads or the grid passes through the inverter, so there are fewer conversion stages and less energy is lost.
