The prices of gas and electricity worry us all and that has made many people choose to install solar panels. And many of those who have already taken the step are now considering attaching batteries.
The energy price Spanish families are becoming more and more concerned and the option of many families has been to invest in alternative energies.
With biomass, gas and electricity reaching record prices, renewable energies have become a more than interesting option. And there is no doubt that the solar energy It is currently the most efficient for its quality/price ratio.
Two discharge powers can be configured: 6.8 kW and 13 nominal kW
The photovoltaic installations Current ones can cover a large part of the energy needs of a home, notably reducing the electricity bill at the end of the month.
The only problem is that when the sun goes down and night falls, the solar panels stop producing and users have no choice but to turn to the electricity grid and pay for the energy consumed.
Sunpower Residential Battery
There are several alternatives to solve this problem. One is the virtual battery of Próxima Energia, although it is associated with an electricity rate that is not compensated in many cases.
Another alternative is to install residential batteries associated with solar panels. In this way, it is possible to take advantage of all the energy production during the day, accumulating the surplus for when night falls or consumption peaks occur.
This is how Sunpower’s scalable battery system works.
We have already told you about some of them at a very good price, but today we present a new product launched on the market by Sunpower, a prestigious North American company in the sector.
Specifically, we are talking about the new Sunpower SunVault residential batteries, which offer a scalable system that starts with a 13 kWh unit capacity and can reach up to 52 kWh. Taking into account that residential photovoltaic installations usually range between 2.5 and 6 kWp, we are talking about a very considerable storage potential.
Sunpower SunVault Features
According to the American company in the official statementUp to five configurations will be available, with capacities starting at 13 kWh and scaling to 19.5 kWh, 26 kWh, 39 kWh and 52 kWh.
These can be configured two discharge powers: 6.8 nominal kW for the 13, 19 and 26 kWh versions, and 13 kW for the 39 and 52 kWh versions. All the batteries in the SunVault range are of the LFP type, that is, lithium iron phosphate cells.
According to Sunpower, SunVault batteries offer a efficiency of more than 86% and its nominal internal voltage is 51.2 V, with the maximum continuous backup output current (AC) being 28.3 A.
In addition, SunVault batteries can operate in an ambient temperature range of -20 to 45ºC and have a protection level IP54. All with a 10-year warranty with unlimited charge and discharge cycles.
“Every homeowner has unique energy storage needs.: Some want the peace of mind of being able to power essentials like a refrigerator and Wi-Fi during an outage, while others want the flexibility of also charging an electric vehicle or running their air conditioner,” said Nate Coleman, Product Manager at SunPower.
“With these new storage sizes and increased power output through multiple inverters, SunVault’s modular configuration allows customers to get the size of storage they need.” safe in the knowledge that they can grow their system as their home energy requirements change”has expanded.
Sunpower makes available to interested parties a calculator with which to determine how many hours of electric autonomy can be achieved with a SunVault battery.
