Trinabest, the energy storage spin-off from Chinese PV outfit Trina Solar, has launched its residential battery storage product on the Australian market, offering two sizes of the company’s lithium-ion phosphate PowerCube.
The 7.2kWh PowerCube 2.0 and 4.8kWh PowerCube mini were unveiled at the All-Energy Australia conference in Melbourne on Tuesday afternoon by Trinabest CEO Frank Qi, who – like various of his competitors – pinpointed Australia as a key market for battery storage.
The two battery storage offerings will be rolled out nationally through Victorian energy solutions company Mpower, which says it will be the sole point of contact – the “one throat to choke” – for service and “advanced support” on the batteries.
Trinabest said it had taken its time selecting the right partner in Australia to roll out its battery storage products, settling eventually for Mpower, which has extensive experience in battery storage – particular in off-grid applications – and offers a number of other products for the residential market.
“The Trina group, like Mpower, aren’t a start-up business with a lot of marketing hype about their solution,” said Mpower’s Chris Leahy. “It’s a well tried and proven product and company.”
Trinbest said the larger battery, the 7.2kWh PowerCube 2.0, will retail for $7,999 fully installed with the company’s PowerBox inverter. Both batteries come neatly cased in a variety of colours.
The system, once installed, is AC-coupled, allowing it to operate independently of the grid during outages, and has the smarts to allow the stored energy to be sold to the grid as well as used in the home.
