For Enphase IQ Gateway & Envoy owners

Enlighten shows what your panels made. Not what they should have.

Your app is good at production. It has never told you what shade is costing you, or why your true-up climbed. That gap is what we measure.

Works with the IQ Gateway and Envoy. 30-day money-back guarantee.

Get started

Independent

Not Enphase. Not your installer.

Your data

We never sell it. Export it anytime.

Read-only

We watch your system. We never touch it.

A real person

Email me. You’ll get a human.

Your whole system, on your phone.

Four tabs. Open any of them, anytime, from anywhere.

Home

Where your power is going right now: solar, home, grid, and battery.

Performance

Each day: what solar made, what your home used, and what went to the grid.

Panels

Every panel's output, as often as your microinverters report it.

Health

Panels, microinverters, and the monitor. Green, or what needs a look.

And we tell you. A panel stops reporting: you hear within days. The monitor goes quiet: you hear within the day.

Enphase IQ Battery

We see your Enphase battery, too.

Nothing to connect. If your gateway has one, it shows up.

How full it is, and its charge through the day
What it charged, and what it gave back, every day
Its health, from Enphase's own figure
How much capacity it has lost since it was installed
The backup reserve it holds for an outage

Example figures.

Three questions about your own roof.

You can answer the first one today. The other two are the ones that cost money.

What did my panels make?

Enlighten: Enlighten answers this well, per panel.

WattHacker: So do we — but that is not why you'd want us.

What SHOULD they have made?

Enlighten: Not answered.

WattHacker: Measured against a clear-sky model for your roof's own geometry.

What is shade costing me?

Enlighten: Not answered.

WattHacker: Measured every month, in dollars at your rate plan.

What silence costs.

Measured on real roofs. Yours will differ — that is rather the point.

One dead panelOne 425 W panel at $0.45/kWh makes about 820 kWh a year — roughly $31 a month.425 W, stops producing: $370a year
Shade you never mappedThe shade analyzer's own annual total on one real roof, priced at that home's rate plan. An estimate, modeled from clear days — your roof will differ.estimated on a real roof: $676a year

“The device is a great way for me to now have insights into my system after SunPower went away, and I was left with no data or expensive month-to-month charge options to see my own data, on my own system.”
“WattHacker founder, Tony, is personally engaged with the product, its development, its improvement and its fine tuning for your specific application.
He understands solar, home electrification, energy storage and savings strategies, and can help you utilize your system data derived with the WattHacker device for improved performance and upgrade planning.

I find the current devise system configuration and the tools extremely useful, easy to install and use. I am looking forward to using and giving feedback on the system and its capabilities to enhance performance and visibility into my home solar system.”

“I had an issue with the first monitor and the owner reached out about the issue I was having before I noticed the issue. He sent me a new monitor and it’s been working great. Customer service alone is worth a 5-star review.”

“An added bonus has been WattHacker.com, which gives us a way to monitor our solar system, better understand its performance and efficiency, and identify opportunities to maximize our energy savings.”
“Tony was an incredible resource as we navigated our home electrification project. There were a lot of moving parts and decisions to make, and he helped us understand our options in a way that was clear and easy to follow. He took the time to explore cost-saving solutions while also keeping energy efficiency and environmentally friendly choices in mind.
An added bonus has been WattHacker.com, which gives us a way to monitor our solar system, better understand its performance and efficiency, and identify opportunities to maximize our energy savings. It's great to have that kind of visibility into how our system is working.
We really appreciated Tony’s knowledge, patience, and thoughtful approach. He made what could have been an overwhelming process feel much more manageable. We're so grateful for his guidance and would highly recommend him to anyone looking to make their home more energy-efficient and environmentally friendly!”

How it works

The monitor arrives. Plug it into any USB port in the house.
It joins your wifi and finds your gateway. You paste one authorization token from Enphase — we walk you through it.
I set your system up personally, and email you when it goes live.

Have a Tesla Powerwall too? Connect it in the app, and it shows beside your panels.

Not happy? 30 days, your whole first order back — monitor, shipping, and anything charged at checkout.
