MyEnergi Libbi Home Battery
Looking to maximise the usage of your home’s energy? For homeowners looking for a contemporary energy storage solution, read more about the Libbi Home Battery.
Product Description
MyEnergi’s Libbi Home Battery is the ideal product for homeowners looking to save their energy and make the most of their solar PV and EV Charger investments. With its versatility in storing surplus energy with your solar PV systems and wind power, the Libbi Home Battery also collects and stores energy from the National Grid during off-peak hours where tariffs are lower.
This enables you to continue using stored energy during peak hours where energy tariffs are steeper. The Libbi Home Battery can also be utilised as a blackout backup during when there is no available electricity; enabling you to stay powered in the event of a power cut.
To top it off, its sophisticated, smart technology has an advanced anti-draining feature that kicks in when plugged into an EV charger (which you can also turn off if needed).
This product saves both hassle and money on your energy bills. Combining both energy efficiency with cost efficiency, the Libbi Home Battery ensures you are prepared for any fluctuations and changes in the energy world.
MyEnergi Libbi Home Battery Features
The Libbi Home Batteries we supply come with a:
- Modular design – with each modules storing 5kWh of electricity, however, can store up to 20kWh when combining 4 modules
- Available in two sizes of 3.68kW and 5kW
- Compatible with other MyEnergi devices including the Zappi PV Charge Station.
- Optimum control with ability to be charged via solar, the grid, and wind energy.
- Adaptable installation - Connect without the extras as the Libbi Home Battery works both as AC and DC with solar PV.
- Anywhere, anytime access – view and control your Libbi from any location with the MyEnergi App.
- Erudite live displays – monitor the electricity your home imports and exports all from your phone.
- Your energy Backup – energy stored using Libbi can be used even through power cuts and blackouts (additional installation costs will apply).
- Anti-draining feature.
