The Boss of Your Powerwall
The Tesla Gateway is like the head honcho of your Powerwall setup. The Powerwall’s busy stashing energy - nabbed from solar or the grid - but the Gateway’s the one steering the ship, making sure it all lands where it’s needed. It’s the clever spark that turns your battery into a proper home energy champ.
In tech terms, it’s the gizmo hooking your Powerwall to your home’s electrics, the National Grid, and your solar panels if you’ve got ‘em.
It’s standard with every Powerwall job - Powerwall 2 or the fancy new Powerwall 3, you name it.

What Does the Tesla Gateway Do?
The Gateway’s got a few ace jobs that make it a total keeper:
#1 Grid Guru
It’s your go-to for the National Grid. Want to charge up on the cheap when rates drop? Or flog extra juice back when your solar’s buzzing? Gateway’s on it.
#2 Blackout Hero
Power goes kaput? It’s got your back faster than you can blink - swaps you to backup and cuts the grid tie so engineers don’t get a nasty surprise.
Once disconnected from the grid, it essentially provides you with your own off-grid system, allowing the Powerwall and solar to continue to provide power to your chosen circuits.
It’s super fast too - switching to off-grid mode takes approximately 25 milliseconds - meaning you’re unlikely to experience any flickering at all.
#3 Monitoring
Your Tesla Gateway’s a proper busybody - it’s constantly gathering the full scoop on your solar output, home energy use, grid reliance, and Powerwall levels.
All that juicy info gets beamed straight to the Tesla App (your fancy energy dashboard), letting you peek at what’s going on in real time, no guesswork needed.
With this goldmine of live data right in your pocket, you’re the boss of your home’s energy.
Fancy tweaking things to save a few quid or keep the lights on when the grid’s having a wobble? It’s all there at your fingertips, ready for you to call the shots.
#4 Solar Buddy
Rocking solar panels? The Gateway makes sure they’re best mates with your Powerwall. Powerwall 3’s got its own inverter for a straight hookup; Powerwall 2 teams up with an external one to bank that sunshine.
Why Is It So Important?
No Gateway, no dice. Without it, your Powerwall’s just a fancy box with no plan.
It’s the bit that makes it smart, safe, and legit - UK rules say it’s got to cut you off the grid in a blackout, and the Gateway’s the enforcer.

Gateway 2 vs. Gateway with Powerwall 3
You’ll hear us bang on about the "Backup Gateway 2" for Powerwall 2 or just "Gateway" with Powerwall 3. Same gig, slight twist.
Gateway 2’s a standalone piece with an external inverter for solar; Powerwall 3’s Gateway rolls with its built-in one - less kit, more slick.
“The Tesla Gateway’s the real star. It’s what ties the whole show together - without it, you’re stuck with a battery and no brains.” - Ben Price, Heatable Co-founder
Alternatives to Tesla Gateway
Wondering if there’s another way? For Tesla Powerwall fans, the Gateway’s your golden ticket - custom-made for the job.

Enphase Ensemble System
Their Encharge battery and Enpower switch combo handles backup and solar. A tidy rival to Tesla’s setup.
SolarEdge Energy Hub
Hybrid inverter with battery smarts - great shout if you’re in the SolarEdge gang.
