The DEYE SUN-14K-SG05LP3-EU-SM2 is a 14kW three-phase hybrid inverter designed for photovoltaic systems with low-voltage battery storage. Its 40–60V battery architecture and two dedicated battery inputs allow for a flexible system configuration, suitable for homes with high energy consumption, guesthouses, offices, workshops, and small commercial premises.
The inverter manages the energy generated by the solar panels, battery, grid, and loads within a single unit. It can be integrated through AC coupling into an existing photovoltaic system and supports the storage of energy supplied by a diesel generator. Six programmable time periods for battery charging and discharging help adapt the system to the consumption profile and energy tariffs.
The model supports up to 22.4kW of maximum PV input power and uses two MPPT trackers, each supporting two strings. In three-phase operation, the output can be 100% unbalanced, with each phase supplying up to 50% of the inverter’s rated power. For loads with high starting currents, the off-grid output can temporarily reach twice the rated power for 10 seconds.

The three-phase output can operate with 100% unbalanced loads, with up to 50% of the rated power available on each phase. In off-grid mode, the unit can deliver twice its rated output for 10 seconds.

Advantages
Power for demanding applications: The 18kW capacity is suitable for three-phase projects with significant loads, provided that the installation is correctly sized.
Management of a high-capacity storage system: The maximum current of 330A supports the charging and discharging of properly sized compatible batteries.
Flexible photovoltaic array: The maximum PV input power of 28.8kW and two MPPT trackers enable the efficient use of panel arrays with different orientations.
Fewer limitations between phases: The 100% unbalanced output is useful in applications where loads are not distributed equally across the phases.
Integration with multiple energy sources: The system can coordinate energy from photovoltaic panels, the grid, batteries, and a generator.
Scalability: Up to 10 inverters can be connected in parallel, allowing a properly designed installation to be expanded.

Compatibility and integration
The inverter supports lead-acid and lithium-ion batteries within the 40–60V range. For lithium-ion batteries, the charging strategy adapts to the BMS through compatible communication. Exact compatibility depends on the battery model, BMS protocol, and firmware version. We recommend checking compatibility before purchase.
The photovoltaic strings must be sized according to the voltage and current limits of each MPPT, including variations in module voltage caused by temperature changes.
Protection and safety
The inverter includes DC reverse-polarity protection, AC output overcurrent protection, thermal protection, AC overvoltage protection, AC output short-circuit protection, DC component monitoring, AFCI, anti-islanding protection, a DC switch, insulation impedance detection, and residual current monitoring. Surge protection is Type II on the DC side and Type II on the AC side.
