The DEYE SUN-4K-G06P3-EU-BM2-P1 is designed for three-phase photovoltaic systems connected to the utility grid. It delivers a rated active power of 4kW and supports up to 6kW of connected photovoltaic power.
Its two MPPT trackers allow two panel strings with different orientations or irradiation conditions to be connected. The 120–1000V MPPT operating range and 1100V maximum input voltage provide flexibility when sizing the photovoltaic array.
The inverter achieves a maximum efficiency of 98.1% and includes protection functions for both the DC and AC circuits. Its IP65-rated enclosure, natural convection cooling and optional monitoring solutions make it suitable for residential and small commercial installations.
Key Features
- Three-phase on-grid operation
- 4kW rated output power
- 6kW maximum PV input power
- Two MPPT trackers with one string per MPPT
- 20A + 20A maximum PV operating current
- Zero Export function
- VSG application
- Smart string monitoring – optional
- Anti-PID function – optional
- AFCI protection – optional
- IP65-rated enclosure
- Natural convection cooling
Benefits
Independent Management of Two Strings
The two MPPT trackers independently optimise the two photovoltaic inputs. This is particularly useful when the panels are installed on surfaces with different orientations.
Flexible System Sizing
The 6kW maximum PV input power allows the photovoltaic array to be oversized in a controlled manner relative to the inverter’s rated output power of 4kW.
Efficient and Quiet Operation
The maximum efficiency of 98.1% helps reduce conversion losses, while natural convection cooling eliminates the need for a fan.
Integrated Protection Functions
The inverter includes protection against reverse polarity, overcurrent, overvoltage, short circuits, excessive temperature, residual current and unintended island operation.
Recommended Applications
- Residential three-phase photovoltaic systems
- Small commercial premises
- On-grid photovoltaic installations
- Systems with panels installed in two different orientations
- Applications requiring the limitation of energy exported to the grid

Compatibility and Important Information
This is an on-grid inverter. It does not have a battery connection or a dedicated backup output for supplying electrical loads during a grid outage.
Using the Zero Export function requires the appropriate configuration and compatible metering equipment specified by the manufacturer.
Accessories for monitoring via GPRS, Wi-Fi, Bluetooth, 4G or LAN are optional. Their availability must be checked separately.
The PV strings must be sized according to the panels’ Voc, Vmp, Isc and Imp values, the temperatures at the installation site and the electrical limits of each MPPT tracker.
Installation, configuration and commissioning must be carried out by qualified personnel in accordance with the manufacturer’s instructions and all applicable regulations.
