WattChop writes your battery its own algorithm, installs it on the site controller, and drops a fresh one whenever your rates change. It runs autonomously — following live grid, load, and solar every cycle — and keeps earning every year you’re subscribed. Run your first Analysis Report free. No credit card required.
Solar panels take what the sun gives them. Meters measure what already happened. The battery is the only piece of the stack that can actually make a choice — when to charge, when to hold, when to discharge.
Most battery systems are wired to a schedule. A sprinkler timer for electricity. Charge at night, discharge in the afternoon, repeat forever. But markets aren't static. Weather isn't static. Tariffs aren't static. A battery running on a schedule is wasting its only real advantage.
Your algorithm follows live conditions every second. When your tariff changes, we drop a new one. WattChop studies your site's tariff, load, and generation, then writes a custom algorithm and installs it on the site controller. It runs autonomously at the edge — following live grid, load, and solar every cycle, and it keeps optimizing even if the internet drops. It works best where the math gets interesting: time-of-use rate structures and high demand charge windows.
WattChop reads your tariff, your building, and your interval data — and solves for the system that delivers the maximum savings. Not the biggest. Not the cheapest. The one the math supports. The answer comes back as an Analysis Report that pairs with your EPC's proposal — the methodology behind the savings number, documented and defensible.
Your algorithm lives on the site controller and dispatches around the clock — following live grid, load, and solar every cycle. No cloud round-trip. No dependency on the internet staying up. The intelligence is on site, working every second of every day.
When your utility reshapes its pricing, WattChop writes a fresh algorithm and drops it to your battery. Not on a schedule — when your rates actually change. That's the difference between an install and a living, ten-year service.
It depends. Dozens of ways — direct hardware commands, BMS integrations, EMS platforms, inverter APIs. We don't build any of them. What we build is the schedule: a 24-hour dispatch map of charge, hold, and discharge setpoints that your battery — or your EMS partner — follows.
Hardware is hardware. We're the intelligence that tells it what to do.
Load your data and WattChop shows you your building — when you actually use energy, what your utility charges you for it, and where the expensive hours hide. The only way WattChop gets sharper is by seeing more buildings. So the parts that don't need to be paid for, aren't. Come one, come all.
Upload Green Button data, CSV intervals, or synthesize from utility bills. See your building's complete energy profile — peak demand, load factor, TOU exposure, seasonal patterns, building classification. Unlimited projects.
Tariff Smart visualization of your building's energy performance in real time. Connect your meter, see your data, track your savings. Free for all users.
Self-commission an eGauge meter in under two minutes. Phase detection, CT programming, register configuration — no truck roll required.
More tools coming. This is just the beginning.
Every building breathes in a pattern. A grocery store's load profile looks nothing like a data center's. A school peaks differently than a hospital.
WattChop uses validated data sources to group buildings by how they consume energy, then uses that similarity to deliver results backed by data — not guesswork. Even without interval data, the synthesizer builds an accurate load profile from monthly utility bills.
This building wakes at 6am and runs hard until 7pm, every weekday, all year. Its worst hours land between 4pm and 8pm in July and August — the same window its utility charges the most for. That overlap is the opportunity.
Seeing your building is free, forever. You pay when you want the answer — how big should it be, and what will it save.
No limits. No catches. No credit card.
How big should it be, and what will it save? Most sizing offsets a percentage of kWh, or follows a rule of thumb, and never asks when your energy is expensive. We size against the bill — optimal size, the diminishing-returns curve, and demand vs. energy broken out. Hand it to your customer alongside your quote and the savings number stops being a claim. It's an Analysis Report, not a proposal — the methodology is the point.
Your battery, optimized every day you’re subscribed. Your custom algorithm, Site Findings, and Daily Receipts — all landing in your own Mission Control dashboard, proving it's working and saving. Hardware and implementation provided by EnergyBoom.

The algorithm is the product. Partners, OEMs, and platforms take it by API and run it inside their own sales tools, monitoring platforms, and EPC workflows — their hardware, their brand.
The optimal system size — modeled against the site’s real tariff, not an offset percentage or a rule of thumb.
A charge, hold, and discharge schedule any hardware can follow — and a fresh one when the rates change.
The algorithm running on site, correcting every cycle against live conditions. No cloud dependency.
