Home energy storage · built for North America

When the grid goes down, your home stays on.

HavenVolt is a wall-mounted home battery engineered around UL 9540A fire-safety testing and cobalt-free LFP cells — with seamless backup switchover and three sizes, 5 / 10 / 15 kWh, that fit real North American homes.

01How it works

Three jobs. One quiet box on the wall.

Store

Charge from rooftop solar or off-peak grid rates, and keep a protected reserve for the next outage.

Watch

The battery management system monitors every cell, while the app keeps a weather-aware backup reserve.

Switch

When the grid fails, essential circuits move to battery in under 20 milliseconds — lights, fridge, Wi-Fi and more.

Energy flow: solar and grid charge the unit; the unit carries essential loads through an outage.

02The line-up

Three sizes. One architecture.

Every HavenVolt shares the same LFP cells, BMS and enclosure platform. Pick capacity by home size and backup goals — and parallel up to four units as needs grow.

03Safety & compliance

Safety is not a feature. It is the architecture.

HavenVolt units are engineered around the UL 9540A test methodology for thermal runaway, built on cobalt-free LFP chemistry with high thermal stability, and protected at three independent levels. Installation guides follow NEC clearance and siting requirements, keeping permits predictable for your installer.

Cell level

Cobalt-free LFP cells

Per-cell voltage and temperature sensing on a chemistry chosen for thermal stability.

Pack level

Thermal barriers

Insulating barriers between modules and a directional pressure-relief design.

System level

Redundant protection

Redundant contactors, arc-fault and ground-fault protection, and a cloud watchdog on duty around the clock.

04For installers & distributors

A storage line your crews will actually like installing.

We grow through a certified installer network — not around it. Dealer partners get protected territories, routed homeowner leads, and a documentation pack that shortens every permit.

Fast, one-visit mounting

Rail-mount design: a two-person crew typically completes the wall mount and wiring in a morning.

Permit-ready documentation

Single-line diagrams, spec sheets and standards files, organized the way plan reviewers ask for them.

Protected territory & leads

Install-consult requests from this site are routed to the certified dealer covering the buyer's area.

Training & support

Online certification plus hands-on commissioning training, with spare parts stocked in a North American warehouse.

Pilot programs start from 10 units, with demo-unit pricing for showrooms.

07Incentives

Storage may cost less than you think.

Federal ITC

Qualified home battery systems may be eligible for the U.S. federal Investment Tax Credit.

State & utility programs

Programs such as California's SGIP offer additional incentives in select markets.

Time-of-use savings

Daily rate arbitrage keeps paying back long after outage season ends.

Incentive availability varies by location and changes over time. This is not tax advice — confirm eligibility with your installer and a tax professional.

08FAQ

Questions homeowners and dealers ask first.

Yes. The unit can charge entirely from the grid on off-peak rates and hold that energy for backup. Solar can be added later without changing the hardware.
