Description
Productinformation in detail
Efficient Storage and Flexible Power Output
Every Deye inverter of the SUN series not only supplies your home or business directly with solar power but also feeds excess energy into a battery storage system if desired. This can significantly reduce your electricity costs. The devices support battery types from lead-acid to lithium-ion; the voltage range of 40 to 60 V and the self-adjusting charging strategy to the BMS of a lithium-ion battery guarantee high flexibility.
Depending on the model, the maximum charging and discharging current varies:
SUN-14K-SG05LP3-EU-SM2: 260 A
SUN-15K-SG05LP3-EU-SM2: 280 A
SUN-16K-SG05LP3-EU-SM2: 300 A
SUN-18K-SG05LP3-EU-SM2: 330 A
SUN-20K-SG05LP3-EU-SM2: 350 A
With these gradations, a Deye inverter always offers the right power for your energy management.
Maximum PV Utilization Thanks to Powerful MPPT Trackers
The Deye inverters of the SUN series are characterized by their advanced MPPT systems, which operate in a voltage range of 160 V to 650 V, ensuring optimal energy yield. Depending on the model, the maximum DC input power ranges from 21,000 W to 30,000 W. Multiple MPP trackers (2/2 + 2) ensure high efficiency even with partial shading or complex roof conditions.
High AC Power and Great Flexibility
Whether 14 kW, 15 kW, 16 kW, 18 kW, or 20 kW nominal power: Every Deye inverter offers enough reserves to respond to power peaks. For up to 10 seconds, the devices can even provide double the nominal power (off-grid), which is very helpful for inrush currents of large consumers in the home or business.
The integrated asymmetrical power output (up to 50% of nominal power per phase) gives you maximum flexibility in load distribution. Thanks to a continuous AC pass-through current of 70 A, the Deye inverters also supply large loads such as charging stations, heat pumps, or other energy-intensive devices without any problems.
Reliable Protection and Robust Design
Deye inverters are equipped with extensive safety and protection features, including DC reverse polarity protection, AC output overcurrent protection, overvoltage protection, short circuit protection, as well as ground fault current and island monitoring. A sturdy housing with IP65 certification protects against dust and water spray, while intelligent air cooling ensures safe operation even at high ambient temperatures.
