MYENERGI LIBBI BATTERY STORAGE

Join us for a run through of a MyEnergi Libbi battery storage system in a beautiful  period home in Glasgow’s West End. 

This home was our first ever MyEnergi Zappi EV charger install back in 2019. Since then, we have installed hundreds. It has become the most popular charger we install and the brand has grown exponentially. As a bonus, retrofit battery installations from February 2024 are at 0% VAT rate. This provides substantial savings to homeowners. 

The client already had solar PV, a MyEnergi Eddi solar hot water diverter and an EV charger, so the only piece missing to complete the renewables eco system was a battery. In homes, storage space is at a premium and we don’t want to take it up with a battery. Ideally, you’d have a garage or outside space where it can go, out of the way.  

Here, there was an external cupboard. We clad this in concrete fire board to provide a flat  surface to mount the equipment on used floor stands to level the equipment on the uneven concrete floor. The Libbi is supplied from an RCD and has a surge protection device to prevent over voltages from the grid damaging expensive equipment.  

The Libbi can work in 2 modes. In AC coupled mode the inverter controls only the battery. In DC coupled mode the inverter controls the battery and solar (also known as a hybrid inverter). The existing solar inverter was working perfectly well and the Libbi was set up in AC coupled mode to work alongside the solar inverter. An advantage of AC coupled mode is that the energy load in the home can be covered by solar generation and the battery discharging at the same time. 

The Libbi is a modular system and there are options between 1 battery at 5.12kWh up to 4  batteries at 20.48kWh. Before installation, we discuss your consumption, what size is  right for you, costs and planned future additions. If the budget doesn’t allow, or things change in future, a battery can easily be added later.  

This install consisted of a 5kW inverter with 4 batteries at 20.48kWh. The usable capacity  of the batteries is 18.4kWh, and they can charge at 4.6kW and discharge at 5kW. General  base loads in a home for essentials such as Wi-Fi, fridges and heating are around 400W  and appliances are 2kW.  

Most Libbi customers we’ve met have used the MyEnergi Zappi app before and love the  user-friendly interface and features. Each day you control and monitor equipment via  smartphone. The app is reliable and gives great information. The beauty of Libbi is all your equipment is visible and shows energy moving in different directions. With a simple click of a finger, the EV charger will not drain the battery, and surplus solar energy can be sent in any order to the home, EV charger, Eddi hot water diverter or battery.
