Premium Lithium’s Powerplant can reduce customers’ electricity bills by up to 60% by storing solar energy during the day and discharging it in the evening. The Powerplant can also charge from the grid, which means it can store cheap, off-peak electricity. Customers on ‘smart’ time-of-use tariffs can save an additional 15% on their energy bills by storing low-cost electricity and discharging it at peak time.
Lower your energy bills by up to 75%
Low cost, high value
Lower CO2 emissions
Because energy is generated, stored and used in the same location, using a Powerplant ensures significant reductions in CO2 emissions by >300kg/p.a. in the average UK home. This helps not only our local environment, but also the planet.
Help Balance National Grid
The Powerplant has a number of extra benefits – beyond the green and economic – for the customer.
Complete All-In-One Solution
The Powerplant offers a complete all-in-one solution with included MPPT charge controller, inverter and modular batteries. This provides a complete turnkey solution for energy independence.
Compatible with All Solar PV Systems
The Powerplant is compatible with all modern smart hybrid inverters. Contact us for installation packages.
The Powerplant has been specifically designed to be modular as this allows for a more tailor-made energy solution for customers based on their specific energy needs. The modular design also allows customers to expand their energy storage easily and cheaply, therefore future-proofing their energy storage.
PremiumCare is Premium Lithium’s proprietary, battery ‘care and repair’ plan and is unique to Premium Lithium. This ensures full, complete battery support, assistance and maintenance as well as a 7 day ‘repair or replace’ promise. We are the only company in the UK providing this level of service.
Pre-order Discounts Up to 30%
With the current raw material and inflation crisis, we are able to offer pre-order discounts of up to 30%. By pre-ordering, the benefits from economies of scaling in production costs can pass on these savings to customers. Depending on the size of the Powerplant and the delivery time, these discounts can be worth over £6,000.
UK Customer Service
We pride ourselves on our customer service and will always answer any questions customers might have about their Powerplant system. Our engineers are always on-hand to check customers’ systems remotely or visit customers’ properties if they believe their Powerplant product is not working as it should be.
The Powerplant is designed to enable customers to become more energy independent and reduce their reliance on electricity supplied via the grid. The Powerplant also helps protect customers against rising electricity tariffs, which are currently increasing at a rate of >9% per year.
20+ Years of Use
We only use the highest quality battery cells, meaning our batteries have an expected minimum lifespan of at least 20 years. This ensures maximum return on investment on the Powerplant as well as long term energy independence.
Most ‘all-in-one’ battery systems weigh over 150kg. This makes them impractical to move around and potentially a falling hazard. The Powerplant’s modular design ensures that the heaviest part is only 85kg, providing a safer, more portable solution. Many UK homes also don’t have strong enough walls to bear such an enormous weight – as the Powerplant stands alone it can be installed anywhere in the home!
The Powerplant has been designed to be safe to use in domestic and commercial premises. All products have undergone extensive safety testing, UKCA and CE certification. For further information on the in-built safety features of the products, please visit the Safety & Regulations page.

Why should I buy a home battery system?
While batteries have been used in electric vehicles for a number of years, it is only recently that the price has come down to make them viable for home use. With a home battery solution like Premium Lithium’s Powerplant, you’ll not only be able to make significant long term savings on your energy costs, but you’ll also reduce your carbon footprint and deal with any potential power outages.
Why should I choose the Powerplant?
Should I install solar panels first before a battery?
Whilst many customers may already have solar panels, significant savings can be made with just a home battery also. Installation savings can be made if the battery and solar panels are installed at the same time and Premium Lithium can assist with installation of solar panels also.
How much money could I save on my energy costs?
Whilst everyone’s energy use and needs are unique, research has shown that the average UK home can save up to 15 - 25% off their energy bills with solar panels and around 50-60% with a home battery. With the rapidly increasing energy costs in the UK, our home batteries have the potential to generate significant, long term savings over their lifecycles.
How do pre-orders work?
With the current raw material and inflation crisis, we are able to offer pre-order discounts of up to 30%. By pre-ordering we are able to benefit from economies of scaling in production costs which means we can pass on these savings to customers. Depending on the size of the Powerplant, these discounts can be worth over £6,000.
What is PremiumCare and how much does it cost?
