02 / OUR OTHER MAIN SOLAR & STORAGE CHOICE

GoodWe ESA.
Power, brought together.

A hybrid inverter, modular battery storage and energy management in one coordinated platform. Explore how ESA can fit a new solar-and-battery installation or a carefully assessed upgrade.

WHY ESA IS IN OUR CORE RANGE

Start with the system.
Then choose the details.

GoodWe is our other main installation brand after Sigenergy. ESA lets us discuss the inverter, storage and monitoring as a joined-up proposal.

Integrated equipment

The all-in-one arrangement brings a matched power module and battery modules together, simplifying the equipment choices to assess.

Capacity around your use

Choose a supported module combination around available solar, evening demand and reserve preferences. More storage is not automatically more useful.

Visibility after installation

SEMS+ supports energy-flow monitoring, device information and alerts. We discuss connectivity, account access and the controls available for your setup.

THE AUSTRALIAN ESA RANGE

Match the phase.
Build the right capacity.

The range includes several power and battery configurations. Availability, approved combinations and network limits are confirmed for your property.

ESA optionPower familyWhat to assess
Single phase · EHA hybrid3–10 kW familyMatch the exact inverter to the roof, permitted connection, battery modules and supported loads.
Three phase · ETA hybrid5–30 kW familyAssess three-phase loads, circuit distribution, battery configuration and export approval.
AC-coupled variantsSeparate BHA / BTA configurationsA possible storage retrofit route. Existing inverter, monitoring and outage operation need checking.

Family names are not a promise of a particular output or export allowance. Model revisions and expansion limits differ; the exact configuration belongs in your quote.

UNDERSTAND THE NUMBERS

Battery energy.
Inverter power.

Two documented LFP modules

Battery moduleRated energyUsable DC energy
GW5.1-BAT-D-G205.12 kWh5.0 kWh
GW8.3-BAT-D-G208.32 kWh8.0 kWh

Usable kWh describes stored energy. kW describes output power. Delivered AC energy is affected by conversion, reserve settings and operating conditions. Other module generations exist; ask for the exact designation.

An example to compare

Example configurationManufacturer specification
Hybrid power moduleGW5K-EHA-G20 · single phase
Nominal AC output5.0 kW
Battery modules2 × GW8.3-BAT-D-G20
Stored energy16.64 kWh rated / 16.0 kWh usable DC
Nominal backup output5.0 kVA, subject to conditions
Maximum PV input for this model10.0 kW DC, with the final array design and approvals checked

This is an illustrative equipment combination, not a package offer or a battery-size recommendation. Actual available power and energy depend on the complete system.

Selected ESA equipment is rated IP66; location, temperature and installation requirements still apply. Figures checked against GoodWe’s current Australian datasheets on 25 October 2026.

BACKUP NEEDS A DESIGN

Keep the right things running.
Know the limits.

ESA has integrated backup functionality. We still need to define the circuits, supply phase, starting loads, reserve and available battery output.

Pass-through is different

A bypass-current rating describes grid power passing through the system. It is not the current the battery can deliver in an outage. The selected inverter and battery combination determines that limit.

Plan around your loads

Discuss refrigeration, lights, internet and pumps before adding heavy cooking, heating or cooling loads. Whole-home backup must be assessed rather than assumed.

Existing solar matters

Ask whether the proposed solar and storage arrangement can keep charging during an outage. Confirm any additional devices, wiring and commissioning work.

WARRANTY IN PLAIN ENGLISH

Know what
is covered.

GoodWe’s current AU/NZ terms list a 10-year limited inverter warranty for ESA 3–10K single-phase and ESA 5–30K three-phase products.

The specified LX D G2 battery modules have separate 10-year product and performance terms. Performance cover uses 70% retained usable energy or a minimum throughput of 3.0 MWh per usable kWh, whichever is reached first. The battery terms cover capacity equivalent to one full cycle per day; operating conditions apply.

Read the supplied-model terms for exclusions, claim deadlines and cost limits. Manufacturer warranty and installation workmanship are separate.

MONITORING & EVERYDAY USE

See where
your energy goes.

The SEMS+ platform helps you follow generation, storage, home consumption and grid flows. Features and data depend on the installed meters, communications, firmware and permissions.

Discuss reserve settings and tariff-based schedules at handover. Automated control is not a guaranteed bill saving; settings need to suit your electricity plan and backup preferences.

BEFORE YOU CHOOSE

Good questions.
Clearer options.

Should I choose Sigenergy or GoodWe ESA?

Sigenergy is our first-choice brand and GoodWe is our other main option. We compare the right configuration for your home, including supply phase, storage, backup equipment, app preferences and budget.

Can ESA be added to my existing solar?

There are hybrid and AC-coupled pathways. We assess your current inverter and system condition before proposing a specific solution, including its outage behaviour.

How large a battery should I choose?

Start with interval usage data, available solar surplus and your priorities. We can compare sensible module configurations and expected use across seasons.

What should be included in the quote?

Exact inverter and battery models, module count, usable energy, backup scope, monitoring, installation work, warranty terms and any applicable incentive assumptions.
