GoodWe ESA Hybrid Inverter

Yes. This single-phase ESA power module can be installed without a battery.

Explore the 5 kW or 10 kW class here. The Australian 10 kW class requests the 9.999 kW EHA-G20 model. Your quote checks your roof, electrical supply and exact module. Three-phase ESA is a separate storage-system family and is not an inverter-only option on this page.

Storage is separate, and backup is not offered without a battery.

A future battery needs an exact ESA module, firmware and installation check. We confirm the compatible batteries, metering, switching and protected circuits together. Battery-package capacity and backup ratings do not describe this inverter-only request.

The standalone ESA installation price stays on enquiry.

We price your exact module and installation in a written quote. GoodWe's Australian inverter warranty Rev5.8 lists the ESA EHA-G20 hybrid power module with ten-year cover, starting at installation or twelve months after production, whichever is earlier. Battery warranty is separate; this does not establish Australian cover for every ESA battery module. PSW’s separate installation and service warranty is 10 years. For equipment supplied and installed by PSW, from installation completion, only where your signed installation agreement includes this commitment. Your written quote confirms whether it does. Existing longer promises and Australian Consumer Law rights remain unchanged. Manufacturer warranties apply separately on their own terms. Keep the model, serial number and handover documents for future support.

Standalone installation is quoted for your site. The written scope confirms the exact power module, mounting, metering, protection, electrical work, commissioning and handover. Batteries, backup equipment and extra site work are separate.

Your Plan carries an unpriced inverter request until the quote is confirmed. An existing battery system’s owned controller is counted once; this request does not add a second inverter to it.

AUD guide includes GST and the inverter contribution to base installation within a new-system package. Panels, storage, backup equipment, battery activation where applicable and additional site work are separate. No battery rebate or complete-system price is inferred from this inverter amount. Replacement-only work needs an itemised quote. Your written quote confirms the exact model, phase, equipment, eligibility and complete installed price.
