The Moonlighter
Lithium Battery Bank Powered with Victron & Proven Automatic Transfer Switch
Does your backup generator pay you back? Yeah — didn't think so. The Moonlighter is our tried and proven battery backup that pulls our clients out of the peak and into the savings. We use legal arbitrage to avoid the peak — AKA dynamic price hikes at 5pm in the afternoon — and when the grid drops, the automatic transfer switch hands your home over to the battery without a blink.
The $98 on-site assessment is applied to your install. Secure checkout powered by Stripe.
Commercial-grade Victron power electronics built into a clean, compact home enclosure.
How The Moonlighter Saves You Money
A battery bank does two things a generator can't: it stores cheap power and spends it when power's expensive — and it keeps the lights on when the grid drops out. Here's how the pieces actually work.
Store Cheap Power
The lithium battery bank charges overnight and during off-peak hours, when the grid sells power for pennies. You're banking cheap electrons instead of paying peak prices for them.
Dodge the 5pm Peak
When demand spikes and rates jump at 5pm, the Victron inverter hands your home's load to the battery — legal grid arbitrage. You stop buying expensive power exactly when the power company charges the most for it.
Auto Transfer Switch
When the grid drops out entirely, the proven automatic transfer switch hands your essentials to the battery in a sub-second blink — no gas, no fumes, no refueling. Silent independence, day or night.
A $35+ Net Positive — On Average
The Moonlighter costs about $153 a month on fixed hardware and setup, and our clients save an average of $189 a month dodging peak rates. That's a net +$36 every month — power that pays you back instead of the other way around.
Victron-Engineered, Lithium to the Core
Measure Your Home First
We come out, measure your load, confirm your Victron + lithium battery bank build, and design your legal peak-arbitrage system. The $98 is applied to your install — so the assessment is effectively free if you move forward.
