Deye 3‑Phase High‑Voltage Hybrid Inverter (e.g. SUN‑20K‑SG01HP3 / SUN‑30K / SUN‑50K series)
A robust, smart, and high-performance solar inverter designed for medium to large residential, commercial, and industrial applications. Ideal for grid-tied, off-grid, or hybrid energy systems, the Deye high-voltage series delivers scalable and efficient power management with flexible battery support and advanced energy control features.
Key Features
-
High‑voltage battery compatibility: Supports lithium-ion or lead–acid batteries between 160 V and 700 V (some models support up to 800 V or 1000 V range) for increased efficiency and scalability. PV Power
-
Hybrid operation: Seamlessly manages solar input, battery storage, and grid power in multiple modes—grid‑tie, off‑grid, AC‑coupled retrofits, or generator backup. PT Online+1Dnea+1
-
Unbalanced 3‑phase output: Offers 100% unbalanced load support per phase, allowing real-world flexibility when phases are unevenly loaded.
-
Parallel expandability: Connect up to 10 units in parallel for multi-kilowatt installations (varies by model) to scale capacity cost-effectively.
-
Smart control & scheduling: Supports programmable battery charging/discharging across 6 time periods, programmable supply priority (PV / Battery / Grid), and remote system control via RS485, CAN, Wi-Fi, LAN, or 4G.

Why It Stands Out in South Africa
-
Reliable backup: In off-grid mode, switchover occurs in under 10 ms—ensuring a seamless UPS-like experience during power outages.
-
Efficient and compact: High DC/AC ratio (up to 1.3) allows installation of additional PV capacity without oversizing the inverter.
-
User-verified robustness: Solar professionals report robust long-term performance, often comparing favorably vs Victron or Huawei in reliability and price.
Model Selection Overview
Model (Example) Battery Voltage Range Max AC Power MPPTs Parallelable Weight & Size Warranty SUN‑20K‑SG01HP3 160–700 V 20 kW / 22 kW 2 Up to 10 ~30 kg, wall-mounted 5 years (extendable) SUN‑30K / SUN‑50K 160–800 V 30 kW / 50 kW 3 or 4 Up to 10 ~75 kg, larger chassis 5 years (BT site dependent) — For higher capacity systems (e.g. 50 kW or 80 kW), expect wider MPPT support, parallel-ready controls, and advanced EMS functions.
