Your Powerwall, finally running on autopilot.
Grid Getter quietly orchestrates your battery so you save more, spike less, and stop watching your utility bill. Set your goals once. We handle the rest, every minute.
Set your goals
Pick a peak target. Toggle the modules you care about.
We watch every interval
Sampling every 60 seconds, aligned to your utility's billing window.
Powerwall acts
Battery covers the spike. Bill stays predictable.
Four modules. One battery. Every dollar accounted for.
Pick the modules that fit your home. They share the same brain — your goals, your utility, your hardware — so they never fight each other.
Cap your peak. Predictable bills.
Watches grid draw every 60 seconds during peak hours and shifts load to your Powerwall before a spike turns into a demand charge. SRP & APS pre-configured.
Live MonitorSee where every watt goes, live.
Real-time dashboard of solar, battery, grid, and home — refreshed every 60 seconds. Stack-ranked top consumers, weather context, and full history exports.
Solar Self-UseKeep your sunshine on your meter.
Holds solar surplus in the battery instead of exporting it for pennies, then releases it on the most expensive minutes of your evening. Cloudy-day forecasts baked in.
TOU OptimizerCharge when it's cheap. Use when it's not.
Reads your time-of-use plan and learns your home's evening load curve. Tops up the battery during super-off-peak hours and discharges during the priciest window.
See your spikes the way Grid Getter sees them.
A real peak-hour simulation: every minute, the line on the right is what your bill would look like if Grid Getter were already running.
* Based on SRP Customer Generation Plan E-27 summer rates. Real April 2026 average savings: $40/mo.

Everything Powerwall owners ask us
What hardware do I need?
A Tesla Powerwall (2, +, or 3) and the Tesla account it's registered under. That's it — no extra meter, no electrician, no rewiring.
Will it work with my utility?
Grid Getter supports utilities today, including SRP, APS, PG&E, SCE, SDG&E, Xcel, and most major time-of-use plans. Don't see yours? Live monitoring still works everywhere.
How is this different from the Tesla app?
Tesla's app shows you what your battery is doing. Grid Getter tells your battery what to do — based on your utility plan, your home's load curve, and your goals. It's the brain that sits on top.
What's the savings claim based on?
$40/mo is the average DemandGuard savings across Phoenix customers in April 2026. Summer demand rates run 2–3× higher in most utilities, so summer savings are typically larger. We publish monthly aggregates on our blog.
Can I disable a module or override it manually?
Always. Every module has a one-tap pause and a manual override. Your battery, your rules — Grid Getter stops the moment you ask it to.
What happens to my data?
Your energy data stays in your Grid Getter account. We never sell it, never share it with utilities without your permission, and you can export everything at any time.
What we're learning from real homes
Monthly aggregate stats, deep dives into utility rate structures, and the occasional weird thing your Powerwall does.
