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.

SMARTSTOR™ is proprietary software developed by Powervault to manage and optimise the scheduling of Powervault solar battery systems. It automatically manages your solar battery in real time, and is an essential for owners of solar panels.
SMARTSTOR™ learns to predict how much energy you’ll need, and when. It understands your individual energy usage patterns and constantly scans the weather forecast, so it knows if sun will be arriving to power your solar panels. It understands when cheap energy from the grid will be available on the latest time-of-use tariffs.

Using artificial intelligence, SMARTSTOR™ looks ahead and makes decisions for you, storing and buying energy efficiently. It doesn’t waste the energy you generate from solar and doesn’t buy expensive energy from the grid that you don’t need. It’s hassle-free, and for solar panel users with a solar battery, letting SMARTSTOR™ automatically manage your solar battery in real time can increase savings by 90% (compared to using just solar panels and a solar battery).

SMARTSTOR™ and our batteries save you money even if you don’t have solar panels. You simply store cheap electricity from the grid, bought intelligently by SMARTSTOR™, which understands your time-of-use tariff.

SMARTSTOR™ is designed to maximise your savings, and most of the time that means maximising the amount of cheap and green solar you store for later use.

Several factors could prevent your Powervault battery from charging, such as a fault in the solar panel system, a malfunctioning inverter, or issues with the battery itself. We recommend visually checking the connections before contacting our support team for further assistance.

If your Powervault battery is not discharging as expected, it could be due to incorrect settings in the SMARTSTOR™ software, a fault in the energy management system, or a problem with the battery itself. Try adjusting the discharge settings in the software and verifying the battery status. If the issue persists, contact our support team for troubleshooting assistance.

While some Powervault batteries are designed to provide backup power during grid outages, they may not be able to sustain power for extended periods or during severe weather conditions. Intermittent power outages or fluctuations could also be caused by issues with the grid, the inverter, or other electrical components. We recommend contacting your utility provider to report the issue and checking the status of your Powervault system for any faults.

Inaccurate information in the Powervault Portal could be caused by connectivity issues, software glitches, or sensor malfunctions. Try refreshing the software and visually checking the connectivity of your Powervault system, then if the problem persists, contact our support team for assistance.

Unusual noises or odors coming from your Powervault system could indicate a potential issue with the battery, inverter, or other components. We recommend immediately turning off the system and contacting our support team for further investigation. Do not attempt to troubleshoot or repair the system yourself to avoid potential safety hazards.

Several factors could contribute to a decrease in battery capacity, such as extreme temperatures, excessive cycling, or aging battery cells. We recommend monitoring the battery’s performance closely and contacting our support team if you notice any significant declines in capacity. Our team can help diagnose the issue and recommend appropriate solutions.
