Deye SUN-20K-SG05LP3-EU-SM2 20 kW zemsprieguma trīsfāžu hibrīda invertors

The Deye SUN-14/15/16/18/20K-SG05LP3-EU-SM2 is a range of higher-power three-phase hybrid inverters spanning 14, 15, 16, 18 and 20 kW, built around a 48 V low-voltage battery platform with a transformer-isolation design. Each unit combines solar generation, battery storage, grid interaction and backup power in a single rugged, IP65-rated package — a flexible, high-capacity solution for larger homes, farms and small businesses on a three-phase supply.

Like the rest of Deye's SG05LP3-EU-SM2 family, these inverters work with both lithium-ion and lead-acid batteries (48 V) and deliver very high charge/discharge currents — scaling with output power from around 260 A on the 14 kW model up to 350 A on the 20 kW. A two-MPPT, three-string design gives plenty of freedom to harvest from roofs facing different directions, while a backup (EPS) output keeps essential loads running during outages, supported by strong surge capacity for starting motors, pumps and compressors. Efficiency reaches up to 97.6%, so very little of the energy handled is lost.

The series is equally suited to on-grid, off-grid and backup setups. AC coupling lets it retrofit onto an existing solar system, multiple units can run in parallel for larger installations, and six programmable time periods make it easy to charge and discharge around time-of-use tariffs. A diesel-generator input adds resilience for off-grid sites, and 100% unbalanced output means each phase can be loaded independently. Built for European conditions, the inverters operate from −40 °C to +60 °C, carry full CE certification to the relevant safety and grid standards (including EN 50549, VDE-AR-N 4105 and G99), and are monitored remotely through the Deye Cloud app via Wi-Fi, Bluetooth, LAN or 4G.

Backed by Deye's standard 5-year warranty (extendable to 10 years), the SUN-14–20K-SG05LP3-EU-SM2 range offers a powerful, scalable foundation for solar self-consumption and dependable home or business backup at higher loads.

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd. · Valid where the final installation site is in Europe. The certificate supplied with your product takes precedence; figures vary by model.

Warranty periods

• Batteries / ESS: ~10 years (BMS often 5 years), plus a performance guarantee: ≥70% usable energy for 10 years, or a set throughput — whichever comes first.
• Runs from date of purchase (capped at 10 yrs 6 mths from factory dispatch). Data logger: shorter (~2 yrs).

What's covered

Defects in material/workmanship, confirmed by Deye inspection — repair or replacement at Deye's option. Hybrid cover includes main unit, LCD and fan, with parts + labour for repair at a service office. After a repair, cover continues for the remaining period or 90 days, whichever is longer.

Not covered

Opened/sealed-broken units; wrong or loose wiring; ignoring the manual; unauthorised repairs/modifications; poor ventilation; force majeure (lightning, surge, storm, fire); transport damage; non-approved batteries run in lithium mode. Battery validity: install within ~3 months, charge within ~48 h, don't leave idle ~6+ months, use the original Deye frame.

Requirements

Installed in Europe, on a fixed solid wall, per the Deye manual. Keep your invoice. Serial number is required to claim.

Your statutory rights (EU)

This warranty is on top of your legal rights against the seller under Directive (EU) 2019/771: seller liable ≥2 years from delivery; defects in the first 12 months presumed pre-existing; remedies are repair, replacement, price reduction or refund. A warranty can never give you fewer rights than the law.

How to claim

Contact your seller/installer first, or a Deye service centre below. Provide: model + serial number, invoice, install date, fault description (error codes/photos/logs). Claims without this info may be rejected.

Deye is a Chinese clean-energy manufacturer best known worldwide for its solar inverters and energy-storage systems. The inverter business operates as Ningbo Deye Inverter Technology Co., Ltd., a subsidiary of the larger Deye Group(Ningbo Deye Technology Group Co., Ltd.), which is publicly listed on the Shanghai Stock Exchange (stock code 605117.SH) since 2021.

While the Deye brand is now synonymous with photovoltaic (PV) inverters and batteries, the group is a long-established diversified industrial manufacturer. Founded and chaired by entrepreneur Zhang Hejun, the company built its early strength in moulds, hardware, plastics, heat exchangers and dehumidifiers before becoming a major force in solar power electronics. The dedicated inverter subsidiary was established in 2007 and has since grown into one of the most recognised names in residential and commercial solar storage.

Business divisions

The Deye Group is a multi-sector manufacturer. Its main areas of activity include:

• Solar inverters and energy storage — the flagship and fastest-growing division (Ningbo Deye Inverter Technology).
• Dehumidification and air treatment — household, industrial and commercial dehumidifiers, constant temperature/humidity machines and custom air-handling equipment, a historic core business.
• Heat exchangers — evaporators, condensers and related components for appliances and HVAC.
• Solar air conditioners and heat pumps — PV-powered cooling, duct systems and water heaters.
• EV chargers and smart-energy IoT accessories.
• Power-electronics R&D — including frequency-conversion control chips and PCBA solutions.

This vertical breadth — from chips and moulds to finished energy systems — gives Deye a high degree of in-house manufacturing control.

Inverter & storage product portfolio

Deye positions itself as a one-stop provider of solar PV and energy-storage (ESS) solutions, spanning residential, commercial, industrial and utility scales:

• String / grid-tied inverters — roughly 1 kW to 136 kW, single- and three-phase.
• Hybrid inverters — roughly 3 kW to 80 kW, including low-voltage and high-voltage battery platforms, single- and three-phase (the SUN-series used widely in Europe).
• Off-grid inverters — for standalone and backup systems.
• Microinverters — roughly 300 W to 2.2 kW for module-level applications.
• Batteries & residential ESS — low-voltage and high-voltage lithium (LiFePO₄) batteries, stackable and all-in-one systems, and Micro Hybrid ESS.
• Commercial & industrial (C&I) ESS — battery cabinets (e.g. 60/120 kWh) and modular C&I storage solutions scaling from around 100 kW to multi-MW.
• Monitoring & smart-energy ecosystem — the Deye Cloud app and platform, data loggers, smart switches, EV chargers and a LoRa-based wireless energy-management system.

Technology & engineering

Deye emphasises in-house R&D and power-electronics innovation. Notable technical approaches include:

• T-type three-level topology with an enhanced SVPWM algorithm, which Deye states improves conversion efficiency by around 0.7% versus conventional SPWM designs.
• Frequency-droop / VSG control, allowing string and hybrid inverters to work directly with diesel generators — valuable in weak-grid and off-grid regions.
• "Smart Load" and "AC Couple" features, repurposing the generator port for flexible load control or for retrofitting storage onto existing PV systems.
• High-voltage battery architecture for higher round-trip efficiency and lower DC currents.
• 100% unbalanced three-phase output and fast UPS-style backup switchover on hybrid models.

Products are typically built to IP65 for outdoor use and certified to international standards (IEC/EN 62109 safety, plus regional grid codes such as EN 50549, VDE-AR-N 4105 and G98/G99 in Europe).

Global presence & market position

Deye has grown rapidly into one of the world's leading suppliers of hybrid and residential storage inverters:

• Products sold in more than 140 countries, with particularly strong positions in the United States, Brazil, South Africa, India, Australia, Pakistan and Europe.
• Widely cited as the No. 1 Chinese hybrid-inverter brand in the United States, a top hybrid-inverter brand in South Africa, and a leading residential hybrid supplier in China.
• Among the global leaders in hybrid-inverter shipments, exporting well over half a million hybrid units per year by the mid-2020s.
• Regularly ranked among the top global inverter brands in industry league tables (e.g. PVBL), alongside names such as Sungrow, Huawei, GoodWe and Solis.

Recognition

• EUPD Research "Top Brand PV" awards for inverters and storage across multiple key markets (2026).
• Named to S&P Global's inaugural Tier 1 Cleantech Companies List.
• Listed and audited as a public company on the Shanghai Stock Exchange, adding financial transparency.
