Powervault
For Business

A Powervault solar battery is a home energy storage system that captures excess energy generated by your solar panels during the day, storing it for use later when the sun isn’t shining. Your Powervault can also be set up to store cheap ‘off-peak’ energy from the grid which you can use instead of buying more expensive electricity from the grid.

The battery stores surplus electricity generated by your solar panels during the day. You can then use this stored energy during periods of high energy demand or when solar generation is low, such as at night. Powervault batteries can also be used to store off peak energy from a time of use tariff, saving even more.

Installing a Powervault can save you money by lowering your electricity bill. Other benefits include cutting your home’s carbon footprint by reducing your reliance on the grid, increasing your energy independence, and contributing to a more sustainable energy future. You can find out more about the benefits of a Powervault solar battery in this insight article.

Powervault batteries use lithium iron phosphate (LFP) technology: we like the fact that it’s safer and more suited to longer duration energy storage and has a longer life span.

This battery chemistry is great for static storage applications but LFP battery chemistry cannot charge when the cell temperature is below zero degrees centigrade.  If forced to operate below zero, LFP cells become unstable and potentially hazardous. It can also have severe consequences for the health and, therefore, longevity of the battery.

It is very rare in the UK for temperatures to remain below freezing for the whole day (on average there are just 5 so-called ‘ice days’ per year, but since 2008 many areas of the UK have had less than 1 per year). If the battery cell temperature does fall below zero, it will automatically stop charging until the temperature rises again. It’s worth noting that it takes a long time for sub zero air temperatures to penetrate to the cell level.

If you use SMARTSTOR with your Powervault battery, the software is designed to cycle your battery continuously , charging and discharging to optimise your energy usage. Simply doing this creates a small amount of heat that helps to keep your battery warm in the cold and stops it being adversely affected by cold weather. 

Some manufacturers claim that their batteries work below freezing. For this to be true, they will most likely be fitted with an internal battery heater. We have chosen not to do this, as it significantly reduces your battery round-trip efficiency and therefore the financial benefit of using the battery at that temperature.

Powervault batteries are designed to be compatible with most solar panel systems. Our team can assess your specific setup to ensure compatibility.

Our batteries are built to last and come with a 10 year warranty. The SMARTSTOR™ system, when activated, will monitor battery health and take proactive action to ensure the cells are protected from over or under charging. For more information, check out our article about battery safety here, or our warranty information here.

The physical footprint of a Powervault battery depends on the model and capacity. The specific dimensions can be found in the product pages, here. Our team can provide specific dimensions and installation requirements based on your needs.

Yes, Powervault offers a web portal that allows you to monitor energy production, battery status, and consumption patterns remotely. You can also adjust settings and schedules as needed for optimal performance.

This is something that we are actively looking into, and some of our partners do provide, so please let us know if you would be interested by filling in a contact form

Installation services are typically offered separately. However, we have our own installation team and work with certified installers who can ensure proper setup and integration with your existing solar panel system.

Powervault batteries are designed to be maintenance free, we proactively monitor all Powervault installations and where necessary can offer remote fixes or site visits to ensure proper functioning.
