Feature

Scalable Power for Diverse Project Sizes

Available in five output ratings — 15kW, 20kW, 25kW, 29.9kW, and 30kW — the ET Series allows distributors and EPC contractors to serve a wide project range with a single product line. The 150% PV input over-sizing ratio maximizes energy harvest even on partially shaded or sub-optimally oriented arrays.

Peak Shaving — Reduce Commercial Energy Costs

The integrated peak shaving function intelligently balances battery discharge and grid import to flatten the demand curve, directly reducing the "extra grid demand" charges that commercial sites incur during peak hours. This is a primary buying trigger for C&I project developers and energy management system integrators.

Dry Contact for Heat Pump & Large Load Control

A built-in dry contact output allows direct integration with heat pumps, EV chargers, pool pumps, and other large loads — scheduling them to run during surplus solar generation periods. This reduces reliance on grid power and adds real value for end users, making the ET Series easy to position in premium residential markets.

High-Voltage Battery Compatibility

Compatible with a wide range of high-voltage (HV) lithium battery systems including GoodWe Lynx Home E and other leading HV battery brands. Communication via CAN/RS485 ensures precise state-of-charge management and extended battery lifespan — a key qualification criterion for sophisticated end customers.

Up to 3 Independent MPPTs — Flexible PV String Design

Three independent MPPT inputs with up to 15A per string give installers maximum flexibility when designing PV arrays across multiple roof orientations or tilt angles — reducing system design time and installation cost.

Application

Large Residential Systems (15–20kW): High-consumption households with EV charging, heat pumps, or pool heating. The ET 15K/20K provides ample backup capacity through the HV battery while managing multiple large loads via dry contact scheduling. Suitable for European and Australian premium residential markets.

Small Commercial & Light Industrial (25–30kW): Retail stores, small factories, office buildings, and light manufacturing facilities with demand charge exposure. The 30kW model's peak shaving capability directly reduces peak demand fees on time-of-use tariff structures — a compelling ROI argument for commercial buyers.

Multi-Unit Residential & Apartment Buildings: The three-phase output is compatible with common area loads in apartment complexes, making the ET Series suitable for shared-energy or virtual net metering applications in markets where these models are gaining regulatory support.

FAQ

Q: What is the difference between the 29.9kW and 30kW models?

A: The GW29.9K-ET is specifically designed for markets (such as Austria and parts of Germany) where local grid regulations cap single inverter output just below 30kW to avoid additional grid-connection requirements. If you are sourcing for the European market, please confirm local grid regulations with your installer or grid operator before selecting a model.

Q: Can the ET 30kW hybrid inverter operate in off-grid mode?

A: The ET Series is primarily a grid-interactive hybrid inverter. When grid power is unavailable, it can supply backup power to loads connected to the backup port using stored battery energy or simultaneous solar generation. Full off-grid island mode for higher capacities is available with the ET 40–50K + STS configuration.

Q: What battery brands are compatible with the ET 20-30K series?

A: The ET Series is compatible with high-voltage lithium battery systems that communicate via CAN or RS485 protocols, including GoodWe Lynx Home E and a wide range of third-party HV battery brands. Contact us with your preferred battery specification for compatibility confirmation.
