At a glance
Efficiency at module level.
Three power variants for different PV modules – with low DC voltage and precise MPPT control.
Concept
Built for decentralized PV systems.
The EQ Microinverter 1T1 is assigned directly to one PV module, enabling flexible system design, rapid shutdown and module-level monitoring.One module, one MPPT
Each module operates at its own power point, independently of the other modules.
Low DC voltage
A maximum input voltage of 60 V supports a safe module-level system concept.
Flexible expansion
Depending on the model, multiple units can be combined within a 20 A branch circuit.
