Deye Three-Phase Hybrid Inverters in Zimbabwe: The Ultimate 14kW-20kW Power Solution
Sona Solar Zimbabwe brings you the heavyweights of energy independence: the Deye SUN-SG05LP3 series. Designed for large residential and commercial applications, these Three-Phase Hybrid Inverters (ranging from 14kW to 20kW) combine high-voltage PV input capability with standard 48V battery safety. This guide covers the full technical datasheets, wiring capabilities, and key features found in the official specifications.

The Deye Advantage: High Power, Low Voltage Battery
Unlike many high-capacity inverters that require expensive high-voltage batteries, this Deye series (SUN-14K to 20K) operates on standard 40-60V (48V nominal) Lead-acid or Lithium-ion batteries. This allows for massive battery banks using readily available and cost-effective lithium modules with a transformer isolation design.
Maximize your solar harvest with a high DC input voltage range (160V-800V). The units feature 2 MPPT trackers with a "2+2" string configuration, allowing for significant solar array flexibility and efficiency (Max Efficiency >97.6%).
These inverters feature support for storing energy from a diesel generator. This ensures continuous power supply even during extended periods of low solar production and grid failure.
The unit supports 100% unbalanced output on each phase, with a maximum output of up to 50% of rated power on a single phase. This is crucial for typical Zimbabwean homes where loads are rarely perfectly balanced across all three phases.

Comparison of the available models in the SG05LP3-EU-SM2 series.
| Model | AC Output Power | Max Charging Current | Max PV Input Power | Max AC Pass-through |
|---|---|---|---|---|
| SUN-14K | 14,000 W | 260 A | 28,000 W | 70 A |
| SUN-15K | 15,000 W | 280 A | 30,000 W | 70 A |
| SUN-16K | 16,000 W | 300 A | 32,000 W | 70 A |
| SUN-18K | 18,000 W | 330 A | 36,000 W | 70 A |
| SUN-20K | 20,000 W | 350 A | 40,000 W | 70 A |
*All models support 48V (40-60V range) Batteries.
System Scalability & Retrofitting
The Deye inverters support extensive parallel capabilities for scaling up commercial power. You can connect up to 10 units in parallel for both on-grid and off-grid operation, creating a massive energy hub capable of powering large commercial facilities.
The system is designed to AC couple to retro-fit existing solar systems. If you already have a grid-tied inverter system, the Deye hybrid can be added to introduce battery backup and smart energy management without discarding your old equipment.
Frequently Asked Questions
No. While it is a "High Power" (up to 20kW) and "High Voltage PV" (800V solar) inverter, this specific series (SG05LP3) uses Low Voltage (48V) batteries. This is advantageous as 48V Lithium batteries are widely available and safer to handle.
The SUN-20K model boasts a massive maximum charging and discharging current of 350A, ensuring rapid battery charging when grid or solar power is available.
Yes, the Deye SUN-20K series supports 100% unbalanced output. This means you do not need to perfectly balance your home or office lights and plugs across the three phases; the inverter manages the load difference automatically.
The inverter supports multiple monitoring modes including GPRS, WIFI, Bluetooth, 4G, and LAN (optional interfaces), allowing for remote monitoring and management via Deye's intelligent platforms.
