Description

The Deye SUN-14K-SG05LP3-EU-SM2 is a three-phase hybrid inverter with 14 kW rated power that combines solar, battery storage, and grid connection in a single unit. It works with low-voltage batteries from 40 to 60 volts (48 V nominal) and, thanks to AC coupling, can be integrated into new installations as well as retrofitted to existing solar systems.

Your Benefits at a Glance

14 kW three-phase power: Reliably covers the demand of larger households. In off-grid operation, the unit briefly delivers twice its rated power (10 s) for loads with high starting currents.
High efficiency: Up to 97.6% maximum and 97.0% European efficiency keep conversion losses low - boosting your self-consumption rate.
100% unbalanced output: Each phase delivers up to 50% of rated power. Ideal when your loads are unevenly distributed across the phases.
Expandable and weatherproof: Up to 10 units can be connected in parallel, and multiple batteries can be linked together. The IP65 protection rating also allows outdoor installation.

More Self-Consumption, More Independence

With two MPP trackers and an MPPT range of 160 to 650 volts, the SUN-14K gets the most out of your solar modules even under changing shading conditions. Six freely adjustable time windows let you control battery charging and discharging precisely - for example, to take advantage of low-cost grid electricity or to buffer load peaks. In the event of a grid outage, the inverter continues to supply your loads and, for additional backup, can even store energy from a diesel generator. A comprehensive protection package - including reverse polarity, overvoltage, and anti-islanding protection as well as integrated residual current monitoring (RCD) - ensures safe continuous operation, while intelligent cooling keeps noise levels below 60 dB(A). Communication takes place via RS485, RS232, or CAN; an optional WiFi, LAN, or 4G module lets you keep track of yields and consumption at all times.
