Charging from solar
The Tesla Powerwall 2 seamlessly integrates with Tesla Solar or third-party solar systems, storing excess energy during the day for use at night or during grid outages. As an AC-coupled battery, it can charge from any solar inverter, making it a flexible and efficient home energy storage solution. When paired with a Tesla Solar Inverter, users can monitor energy production, storage, and usage through the Tesla app for full system optimization.
Without solar system
Even without solar, the Powerwall 2 can charge from the grid during off-peak hours when electricity rates are lower and discharge during peak hours, helping to reduce energy costs. It also provides automatic backup power during outages, ensuring essential appliances stay powered. With smart scheduling and energy management, users can optimize their energy usage for greater savings and efficiency.

Battery Storage FAQ's
At Heatable, we only install battery storage systems from the best home battery brands.
Our most popular being the all-mighty Tesla Powerwall 3 (we’re one of the UK’s largest installers of Powerwalls, and currently hold a Tesla Premium installer status).
We’re also proud installers of SigEnergy, and Alpha ESS battery storage systems.
If there's a particular battery you’d like to discuss, ask our team.
There's a few different types of battery storage systems, but one clear winner.
In terms of the actual battery technology:
Lithium-ion batteries
The most popular and widely recommended. They offer high efficiency, long lifespans, compact size, and deep usable capacity, but come with a higher upfront cost.Lead-acid batteries
Cheaper but larger, heavier, less efficient, and have much shorter lifespans.Other battery technologies
Such as solid-state, flow, sodium-sulfur, nickel-cadmium, and zinc-bromine exist but are not suitable for domestic use and are mainly used in commercial or grid-scale projects.
And, installation types:
DC-coupled systems
Connect directly to solar panels and are more efficient but cannot charge from the grid and are less suitable for retrofits.AC-coupled systems
More flexible, work well with existing solar setups, allow grid charging, and don’t affect feed-in tariffs, though they cost more.
