Growatt is making a push for homeowners who want rooftop solar to do more than just trim their daytime electric bills, introducing a new residential energy system called MINA for the Australian market that combines hybrid inverter technology, modular battery storage, backup power support, and monitoring in one setup, PV Magazine Australia reported.

Here's what to know

According to Growatt, the MINA platform is built for single-phase homes. It is available with inverter capacities from 3 to 10 kilowatts and storage configurations ranging from 5 to 30 kilowatt-hours.

For homeowners, adding battery storage is one of the best ways to protect a home during outages, save money on energy, and move closer to going off-grid. If you're comparing options, it may be worth exploring EnergySage's free tools to get information about home battery storage options, including competitive installation estimates. EnergySage has teamed up with the electrification brand Qmerit to guarantee you get the best price on home battery storage solutions.

Another option is Pila, which offers excellent battery backup options. Its plug-and-play batteries are priced at a fraction of what a whole-home backup system would cost, making them a more approachable starting point for some households.

More background

Growatt said the setup can use as many as three maximum power point trackers, with one string on each, plus a 2.0 DC-to-AC ratio and 18 amps of input current for each tracker. The configuration is intended to work with newer high-current solar panels.

Growatt said its optimizer manages battery modules individually, helping reduce the effects of differences in charge level, operating history, and aging.

That design means a household could begin with less storage and expand later if its energy demands rise, whether from an EV, more appliances, or a desire for stronger backup power.

"This makes MINA especially suitable for households whose energy needs may change in the future," the company said.

The expand-as-you-go model could make it easier for families to scale up their home energy system without having to replace everything at once.

What's being done?

Growatt is also marketing MINA as a resilience tool for households dealing with power outages.

Growatt said the system has a 63-amp backup connection, switches over in under 10 milliseconds during outages, and can deliver 150% peak output for essential loads. When paired with rooftop solar, a battery system like this can help keep lights, refrigeration, internet service, and other important devices running when the grid goes down.

Battery storage is also one of the clearest ways for homeowners to cut peak-hour energy costs and make better use of the solar power they already produce.

On the installation side, Growatt said integrated carrying handles and plug-and-play connections can reduce labor time, with the hardware stack taking about 10 minutes and setup plus diagnostics taking roughly the same amount of time.

The unit can sit on the floor or mount to a wall and comes with Type II surge protection, arc-fault protection, natural cooling, IP66-rated housing, remote monitoring, and virtual power plant readiness. Growatt also said that a future 25-kilowatt bidirectional DC charging feature is planned for vehicle-to-grid use, though it is not yet commercially available.

Growatt Vice President Lisa Zhang described the MINA system as a scalable, future-ready solution for evolving residential energy needs.

"MINA reflects Growatt's commitment to making clean energy smarter, simpler and more accessible for homes around the world," Zhang said.
