Australian Launch: GoodWe’s New ESA Series Home Battery 

Solar manufacturer GoodWe will be showing off its new ESA all-in-one home battery systems at the All Energy Conference in Melbourne next week. There’s been interest building in Australia regarding this new series — here’s a closer look.

What Are The New GoodWe ESA Battery’s Specifications?

• Single-phase.
• LFP (Lithium Iron Phosphate) chemistry.
• Available in 3–10 kW inverter options.
• Modular system — 5 kWh or 8 kWh modules. Up to 48 kWh per stack, with a maximum of 6 stacks in parallel.
• Ability to mix old and new battery modules.
• 63 A backup support.
• <4ms  switching time to backup.
• Battery voltage range: 350 ~ 550V
• 2–4 Maximum Power Point Trackers (MPPTs). 4 MPPTs on the 8 kW and 10 kW inverters.
• 1C charge/discharge rate.
• Dual output ports for flexible load management.
• Convection cooling (fanless).
• PV oversizing: Up to 200 per cent.
• Noise level: < 30 dB.
• IP66 rated for indoor and outdoor installation.
• Six-layer safety protection, including aerosol fire suppression and AI-driven AFCI 3.0, which detects and prevents arc faults.
• Real-time visibility and control via the GoodWe SEMS portal and app

As for estimated retail pricing, that’s not clear; but GoodWe gear is usually priced towards the budget end of the market. The new ESA is Clean Energy Council approved and a full datasheet can be viewed here.

Warranty Details MIA?

Missing from the press release were details regarding warranty, and I haven’t been able to locate that information on GoodWe’s Australian website as yet. Other GoodWe batteries such as the Lynx F G2  have had a 10-year product warranty and a 10-year performance warranty.

The warranty document for the new ESA is something you’d want to get hold of and go over carefully first if you’re considering buying one.

Old Vs. New GoodWe ESA

The new series is quite a step up from the previous generation in terms of looks and features.

The original only had a 5kW inverter and 10.8 kWh of storage, and fewer other bells and buzzers. While the old ESA appeared on GoodWe’s Australian website for a while, I’m not sure if it ever actually reached our shores and I don’t remember seeing it on the CEC’s approved list.

Here’s a video showcasing the new ESA:

Commenting on the new battery, Country Manager for GoodWe Australia Dean Williamson said:

“Australians are looking for energy solutions that are powerful yet simple. The ESA takes the guesswork out of solar and battery pairing while providing full home backup right out of the box. This is what the future of home energy looks like: simple, safe, and smart. The ESA gives Australians the confidence to take control of their power.”

GoodWe unveiled several new/ish home electrification goodies – including the new-generation ESA — back in June this year at Intersolar Europe, and now it’s Australia’s turn to see it in the flesh (so to speak).

The company will showcase the new ESA Series at All Energy Australia in Melbourne next week (stand EE135) and will have a couple of product launch presentations at the event: on Wednesday 29th October, 3.15pm-3.30pm and Thursday 30th October, 10.45am-11am.

GoodWe has had a long association with Australia. The company was founded in 2010 in China and  began shipping GoodWe inverters to Australia in 2012, then expanding its product portfolio to include energy storage solutions in 2020.

The ESA adds to the rapidly growing list of choices Australians now have in home batteries. The CEC’s approved battery list currently has over 100 brands covering 1,000 models. CEC-approved batteries are eligible for the federal government battery rebate.

You can see how a selection of residential energy storage solutions stack up side-by-side on specifications and estimated pricing on SolarQuotes’ home battery comparison table. We’ll have the new ESA on the table soon.
