Bluetti – Home backup battery

Bluetti – Home backup battery

As the National Grid ESO (Electricity System Operator) warns of power cuts this winter we’ve had an increasing number of inquiries about home backup battery systems for UK homes, which are also known as – and double up as – uninterruptible power supply (UPS).

Whilst previously not very common for homes UPS systems have been used by businesses for decades, providing backup power to essential services when the grid falters.

As the cost of energy escalates, and everyone looks for energy saving options and to secure their own power generation capacity via solar PV or wind, backup power systems make even more sense. Just like demand flexibility services, batteries enable you to avoid buying energy at times of high demand, when electricity prices rise, and to operate completely independently from the grid.

In this post we look at the Bluetti EP500Pro home backup battery – a new system designed to power a whole house for a day or two in the event of an unexpected outage.

Bluetti is a relatively new player in the energy storage industry, who launched their first product on Amazon In July 2019. In 2020 they released their AC200 product on Indiegogo as a crowdfunding project and pulled nearly 7 million dollars in two months. Their HQ is in Vegas, Nevada.

They also sell a range of portable power stations for camping trips and outdoor events, expansion batteries, and solar generator kits which include PV panels, charge controllers and batteries with all the ports you need for a an off-grid life.

All-in-one Backup Power Station

The Bluetti EP500Pro is a standalone battery power system with a 5100Wh LiFePO4 battery pack and a 3000W rated pure sine wave AC inverter. It holds enough power to run a family camping trip, cabin workshop, or even your whole house for a day or two, presuming it’s not too energy hungry. Up to 14 outlet sources allow you to power anything from laptops and air conditioners to your electric vehicle.

Seamless UPS Backup

The EP500Pro will automatically become your home energy source for essential loads when the electricity grid goes down. You can also pair it with up to 1200W solar input to recharge or to keep your appliances running without depleting the battery.

The EP500Pro also features a clever battery management system to manage the charge and discharge cycles for improved safety and durability. It even comes with a built-in dual-core processor and Internet connection, meaning the EP500Pro’s firmware can be upgraded through your internet connection without you needing to lift a finger.

The EP500Pro is currently on sale at £5,699.00 but usually sells for £5,999.

You can order it online directly from Bluetti.
