Growatt MINA Smart Home Energy Storage System Revolutionizes Residential Power
Growatt has introduced MINA, a smart all-in-one home energy storage system designed specifically for residential solar markets. The launch marks a significant step in making home energy management more accessible, efficient, and adaptable for homeowners looking to reduce their reliance on the grid and maximize their solar investment.
About Growatt
Founded in 2011 and headquartered in Shenzhen, China, Growatt is a global provider of distributed energy solutions. The company specializes in sustainable energy products including PV inverters, energy storage systems, EV chargers, and smart energy management platforms. Growatt serves customers in more than 180 countries and has become one of the leading residential inverter suppliers worldwide.
What Makes MINA Different
The MINA system integrates a hybrid inverter and battery storage into a single compact unit, simplifying installation and reducing the space needed inside the home. This all-in-one design eliminates the complexity of managing multiple components, making it easier for installers to deploy and for homeowners to operate.
Key features of the MINA system include:
- Modular battery design allowing capacity to scale from 5 kWh to 30 kWh
- Compatibility with both single-phase and three-phase power systems
- Built-in backup power capability for use during grid outages
- Support for both new solar installations and retrofits for existing PV systems
- Integrated smart energy management for optimizing self-consumption
Designed for Flexibility
One of the strongest aspects of the MINA system is its adaptability to different household needs. The modular battery structure lets homeowners start with a smaller capacity and expand later as their energy demands grow or as they add electric vehicles and heat pumps to their homes. This scalability protects the initial investment and provides a clear upgrade path.
The system supports AC-coupled retrofits, which means homeowners with existing solar arrays can add MINA without replacing their current inverters. This lowers the barrier for entry into home energy storage and appeals to the millions of households globally that already have solar panels installed but no storage solution.
Smart Energy Management
MINA connects to Growatt’s ShinePhone app, giving users real-time visibility into their energy production, consumption, and battery status. Homeowners can set operating modes based on their priorities, whether that is maximizing self-consumption, prioritizing backup reserves, or taking advantage of time-of-use electricity rates.
The system’s intelligent algorithms learn household consumption patterns and adjust charging and discharging schedules automatically. During periods of high solar generation, excess energy charges the battery instead of being exported to the grid at low feed-in tariffs. When electricity prices peak in the evening, stored energy powers the home.
Safety and Reliability
MINA uses lithium iron phosphate (LFP) battery chemistry, which is known for its thermal stability and long cycle life compared to other lithium-ion chemistries. The system includes multiple layers of protection including overcurrent, overvoltage, and temperature monitoring to ensure safe operation in residential environments.
The unit carries an IP65 rating, allowing for both indoor and outdoor installation. This gives installers flexib
