SUN-12K-SG04LP3-EU Hybrid inverter 12.0kW 1-ф/220

Deye SUN-12K-SG04LP3-EU — three-phase low-voltage hybrid inverter with 12 kW rated power (380V output) for commercial and home solar installations. It operates with low-voltage 48V battery banks, delivering an industry-leading charge/discharge current of 240A and supporting 100% unbalanced output per phase.

Typical Applications:

• Three-phase home backup for complex unbalanced layouts, delivering full power to one single phase
• Scalable B2B modular energy storage packs (parallel capability up to 16 units in parallel)
• AC coupled retrofitting for expanding existing grid-tied commercial solar stations

Pay attention: features a robust IP65 weatherproof metal enclosure and a touch-screen programming panel. The giant 240A charging current requires heavy-duty DC copper cable cross-sections (minimum 50-70 mm²).

Deye SUN Hybrid Solar Inverters — The Industry Standard for Off-Grid Power Stability in Ukraine

The Deye SUN hybrid solar inverter series stands as the most recognized and requested off-grid energy storage solution in Ukraine. Designed for maximum versatility, the Deye family covers low-voltage single and three-phase models (operating with 48V battery banks, delivering an industry-leading charging current up to 240A on 12 kW), as well as heavy commercial three-phase high-voltage systems up to 50 kW (compatible with 160V–800V battery strings). The core engineering highlight of the Deye SUN series is its structural flexibility: supporting 100% unbalanced three-phase output, seamless AC coupling retrofits, and a dustproof/waterproof steel enclosure rated IP65.

Typical Applications for Deye SUN Series

• High-Efficiency Backup for Complex Phase Layouts: The 100% unbalanced phase output allows Deye to divert full single-phase power capacity onto the most heavily loaded phase without tripping adjacent phases.
• Scalable Commercial Solar Arrays (Up to 16 Units): Parallel capacity up to 16 units lets B2B engineering firms build massive modular energy storage systems for manufacturing plants, offices, and cold storage warehouses.
• Dynamic AC Coupling & Diesel Generator Auto-Start: Deye SUN dynamically mixes PV solar, grid utility, and backup generators. The integrated AC coupling frequency shift control allows it to retrofit legacy grid-tied solar systems.

What Differentiates Deye SUN from Competitors

A key B2B advantage of the Deye SUN series is its ability to discharge and charge low-voltage (48V) battery packs at exceptionally high currents. This allows the system to rapidly recharge massive battery banks during short grid-on intervals.

When Deye SUN is NOT Suitable

• For simple single-phase residential off-grid sites under 6 kW where a large three-phase system is commercially redundant — select the Veichi SI range.
• For B2B projects requiring a solid, straightforward three-phase solar hybrid without high-end AC coupling features — select the rugged Veichi VH (VHT) range.

Our Practical On-Site Observations

Deye SUN boasts the largest number of pre-programmed Lithium battery BMS protocols in our catalog. Supporting over 30 battery brands via CAN/RS485 data buses, installers must select battery type Lithium in the menu and specify the correct BMS protocol index (such as 00 for Pylontech, 12 for Felicity, etc.). Pay careful attention to DC power cabling dimensions — running a 240A charging cycle through undersized DC cables will cause extreme heat buildup and trigger inverter emergency shutdown. Premium compatible batteries are available in our UPS lithium batteries catalog.
