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.

Compatibility and Important Information
This is an on-grid inverter. It does not have a battery input and cannot provide backup power when the utility grid is unavailable.
The export-limitation function requires a compatible meter or metering equipment that has been correctly installed and configured.
The maximum recommended photovoltaic array power must not be confused with the inverter’s rated AC output power.
The PV strings must be sized according to the panels’ Voc, Vmp, Isc and Imp values, the limits of each MPPT tracker and the minimum and maximum temperatures at the installation site.
Compatibility with the distribution system operator’s requirements must be checked before purchase and installation.
Installation, configuration and commissioning must be carried out by qualified personnel in accordance with the manufacturer’s instructions and all applicable regulations.
