Polar Battery 5.12kWh

If you’ve got solar panels in place, you can charge it for free and save the sun’s energy for later.

If you’ve not got solar panels, use smart tariffs. On a smart tariff, your battery charges when energy is cheaper than normal.

Either way, that lovely cheap energy in your battery will supply your home when you need it.

Available in 4.8kWh and 5.12kWh options, the ALPS series battery offer a compelling
blend of affordability and performance.
Harness renewable energy, reduce reliance on the grid, and enjoy significant savings on electricity bills.
Seamlessly integrate with your existing setup and take control of your energy usage, empowering your energy independence efficiently and economically.
