GivEnergy 20 kW 3‑Phase Gen 3 Hybrid Inverter (GIV‑3HY‑20.0‑HV)

GivEnergy 20kW 3‑Phase Gen 3 Hybrid Inverter: The Commercial‑Grade Inverter for High‑Throughput Solar and Battery Systems

The GivEnergy 20kW 3‑Phase Gen 3 Hybrid Inverter is purpose-built for large-scale residential and commercial energy systems. With a huge 30kW solar input capacity and 20kW charge/discharge throughput, it’s engineered to handle complex energy loads while giving businesses and property owners full control over when and how they consume or export energy.

This powerhouse hybrid inverter supports both AC and DC coupled battery systems, integrates seamlessly with dynamic tariffs, and offers built-in EPS functionality to support critical loads during outages.

Unmatched Capacity for Demanding Sites

This 20kW inverter is ideal for installations requiring serious throughput, whether it’s a commercial unit, agricultural property or multi-tenant building. It supports 30kW of solar input across dual MPPTs, and delivers up to 20kW of power to the site or batteries with 50A charge/discharge capability.

• Massive 20,000W output power and 30,000W PV input
• Dual MPPT tracking with 2 strings per tracker
• Pass-through current of 30A

Smart Monitoring and Network Integration

With built-in WiFi/LAN connectivity, this inverter can be monitored remotely via the GivEnergy portal or mobile app. It supports EMS control through RS485+2 ports, enabling detailed load management and third-party integrations where required.

Businesses can access real-time performance data, remotely adjust settings, and even enrol in grid services and export schemes with full control and visibility.

EPS Backup for Critical Operations

Like its 11kW counterpart, the 20kW inverter includes EPS functionality, but at a commercial scale. With a 29A backup output and sub-10ms switching time, it ensures key loads remain powered during outages, making it suitable for operations relying on continuous supply such as refrigeration, IT systems or production equipment.

Commercial Energy Control with Smart Tariff Support

This inverter is designed to maximise return on energy investment. With full support for flexible and agile tariffs, users can schedule charging from the grid when rates are lowest and discharge when energy prices peak. This makes it an ideal fit for SEG export schemes and commercial environments looking to reduce reliance on imported power and stabilise costs.
