GoodWe Shows Off New Home Solar Gear

Chinese inverter manufacturer and smart energy solution provider GoodWe recently showcased several new/ish home electrification goodies – including an all-in-one solar battery system.

All-In-One ESA Home Battery

Among the solutions GoodWe displayed at Intersolar Europe held in Munich, Germany last month was its new single-phase ESA 3-10 kW/5-48 kWh all-in-one battery system. 5  kWh or 8 kWh battery modules can be used in the ESA system, with up to six modules per stack.

Blackout protection features offer a claimed switching time to back-up operation of below 4 milliseconds, which is pretty darned quick. Owners may not realise there’s a blackout happening if they are only using backed-up circuits at the time, which can be a double-edged sword unless the system sends out an alert and the owner sees it.

On the safety side, GoodWe says the new ESA offers 6-layer protection architecture and advanced features such as AI-driven Arc Fault Circuit Interruption (AFCI) 3.0. This type of protection is a type of circuit breaker designed to prevent electrical fires by detecting and interrupting arcing faults in electrical wiring.

An ESA is listed on GoodWe’s Australian website, but is quite different in form and features to the product displayed at Intersolar (pictured above), and no ESA models are on the Clean Energy Council’s approved batteries list (yet).

To get a general feel of the nature of the company’s home battery gear, check out GoodWe battery reviews from Australian owners here. By the way, SolarQuotes founder Finn Peacock hasn’t been a fan of GoodWe batteries to this point (the reviews page explains why) – but you can see home battery brands he recommends here.

New EV Charger – HCA G2

GoodWe also showed off the second generation of its AC single- and three-phase EV chargers — the HCA G2. The HCA G2 offers advanced functions including dynamic load balancing, which the original HCA didn’t offer. EV chargers represent a significant load when cranking away at full tick, and a charger with dynamic load balancing can adjust how much power it draws so that it doesn’t trip a home’s main breaker when other appliances are also in use.

There’s further detail on the HCA G2 here. The HCA G2 is not yet listed on the Australian GoodWe site.

You can see what Australian owners think of the company’s first-generation HCA devices in our GoodWe EV charger reviews, and compare EV chargers side-by-side here.

Mystery Hot Water Heat Pump

In the image above on the left is what looks to be the company’s new all-in-one heat pump hot water system. No further detail was mentioned in GoodWe’s release and I couldn’t find it on the company’s Australian or global website. But if you want to learn about heat pumps along with information on brands and models currently available in Australia (and much more), check out our hot water heat pump system guide.

New(ish) Hybrid Inverters – ET G2

More recently, GoodWe has also formally launched its ET G2 series three-phase hybrid inverter series globally, which was launched in Australia late last year.

Available in 6kW, 8 kW, 10 kW, 12 kW and 15 kW output capacities, the ET G2 offers  an inbuilt smart meter, smart operation mode for maximising solar energy self-consumption, along with UPS-level backup mode (<10ms) in case of power outages.

GoodWe says the ET G2 Series has been enhanced for compatibility with high-power solar panels, with a maximum of 16A input current per string. The ET G2 is compatible with a bunch of batteries.

Listed on GoodWe’s Australian website (and on the CEC’s approved inverter list), the datasheet for the ET G2 can be viewed here. You can also check out reviews of GoodWe inverters from Australian owners. To this point and generally speaking, GoodWe inverters have offered good value for money and are well-supported here in Australia — the company has an office in Melbourne.
