GoodWe GW3000-ES-20 - Single Phase, 3kW Hybrid Inverter

Description GoodWe GW3000-ES-20

Today, more and more people are turning to backup power solutions. The GoodWe GW3000-ES-20 from the ES G2 series is a 3kW single-phase hybrid inverter that is specially designed for residential homes and apartments. It is quiet, reliable, and fits well into everyday life.

Technical features that are truly impressive

This inverter has an efficiency of up to 97.6% - that is, almost all the energy from the panels goes into operation, without major losses. The nominal power is 3 kW, but can withstand short-term overloads. The GW3000-ES-20 model has one MPPT tracker with a maximum current of 16 A, which is enough for a typical home installation with 8-10 panels.

It is hybrid, that is, it works with solar panels, batteries (low-voltage, 40-60 V, for example GoodWe Lynx ) and a regular network. Charge/discharge up to 60 A - the battery is filled quickly. There is a UPS function: when the power goes out, it switches to the reserve in less than 10 ms so that the computer or refrigerator does not turn off.

The coolest thing is passive cooling without fans. The inverter is completely silent, as many praise in reviews. The large radiator and smart design dissipate heat naturally, without moving parts. This means less dust inside, greater reliability and zero noise - ideal for the home.

Why specifically for housing?

The main feature of the GW3000-ES-20 is silence. You can hang it in a garage, hallway, balcony or even a pantry, and no one will hear the buzzing, especially at night when it is powered by batteries. IP65 housing - not afraid of moisture or dust, withstands temperatures from -25 to +60°C. Compact, weighs about 15-18 kg, easily mounted on a wall.

It is suitable for private houses, apartments with balcony panels or summer houses. The power is enough for lighting, appliances, pumps or even part of the heating. With a 5-10 kWh battery, it provides real autonomy in the evening or during blackouts.

The modes are smart: during the day, the maximum from the panels goes to the house, the excess goes to the battery, and if necessary, to the grid (with export restrictions for green tariffs). There is a mode for cheap night tariffs - it charges the battery from the grid.

Smart home integration

Many people install such an inverter precisely because of its compatibility with Home Assistant and OpenHAB . Home Assistant has official integration - it connects via a local network or via the SEMS cloud, shows everything: generation, battery charge, consumption. You can make automations: turn on the boiler when the sun is shining, or send notifications when the battery is low.

It also works with OpenHAB via Modbus or community scripts/MQTT. Users on the forums write that the setup is simple, and then everything is stable - you manage the energy as you want.

Advantages in real use

Complete silence thanks to passive cooling.
High efficiency and fast backup.
Flexibility with batteries.
Easy installation and long warranty (up to 10 years).
Integrates well into a smart home.

For an average family with a 3-5 kW solar station, this is one of the best options in terms of price/quality. Not the most powerful, but for a home – just the thing. If you are planning a hybrid system with batteries and want silence – be sure to look at the GoodWe GW3000-ES-20 . It pays for itself in a couple of years, and provides comfort immediately.
