Tesla Solar Batteries & Inverters
Professionally installed by Viable Power
At Viable Power, we install the Tesla Powerwall, one of the most advanced home battery systems available today.
Sleek, powerful and intelligently controlled, the Powerwall stores your solar energy for use day and night, reducing reliance on the grid and keeping your home powered during outages.
We’re approved Tesla Powerwall installers across Surrey, Hampshire and the South East, helping homeowners add reliable, future-ready energy storage to their solar systems.
It’s one of several trusted brands we work with to deliver premium, long-lasting performance for our customers.
Why Choose the Tesla Powerwall?
Tesla is a global leader in clean energy technology, and the Powerwall brings that same engineering quality and innovation to residential energy storage.
Each Powerwall provides a usable capacity of 13.5 kWh and delivers up to 5 kW of continuous power (7 kW peak) — ideal for most UK households.
Unlike many battery systems, the Powerwall is an all-in-one unit that combines a lithium-ion battery, inverter and intelligent energy management system. This design simplifies installation, saves space and delivers efficient performance straight out of the box.
The Powerwall is compatible with both new solar installations and existing PV systems, making it a versatile choice whether you’re upgrading or starting fresh.
Tesla’s advanced software automatically manages your solar generation, battery charging and grid use. Through the Tesla mobile app, you can track solar production, consumption and battery status in real time, and set charge or reserve preferences. The system learns your household energy patterns and adjusts operation to maximise self-consumption and savings over time.
Reliable Backup Power When You Need It
One of the major advantages of the Tesla Powerwall is its built-in backup capability.
When the grid goes down, the Powerwall switches to battery power in under a second — fast enough that most households won’t notice the change.
It can keep essentials like lighting, Wi-Fi and refrigeration running for hours or even days, depending on your setup and energy demand. You can also reserve a portion of the battery exclusively for backup use, offering extra peace of mind during storms or power cuts.
With an IP67-rated weather-resistant enclosure, the Powerwall can be installed indoors or outdoors, making it ideal for UK homes where internal space may be limited.
Every unit is backed by Tesla’s 10-year warranty, guaranteeing the battery will retain at least 80 % of its original capacity after a decade of use — one of the strongest warranties in the industry, with unlimited charge cycles included.
