Quad microinverters · Kingston, Canada

Every panel,
on its own terms

One Sparq microinverter powers four panels and tracks each one independently, so a cloud, a chimney, or a leaf costs you one panel, never the roof.

Watch the overview

I'm a homeowner

Watch a story · a real install

Built one roof at a time.

A Quad goes under the panels. AC wiring runs to the main panel. In dual mode, the array can keep powering the home when the grid is down.

Over six thousand units ordered in June 2024. Another ten thousand in August.
A new thirty-thousand-unit order, about sixty megawatts, in March 2026.
Expanded to C$32 million in May 2026.

Watch the whole job For homeowners

Every panel in the system
works for itself

Shade one panel on a string inverter and the whole string slows down. Shade one panel on a Quad and you lose one panel. That's the Quad advantage.

The engineering

Three breakthroughs, one microinverter

The engineering choices behind the Quad architecture, and what each one is for.

Proprietary Quad architecture

One microinverter powers four PV panels with individual MPPT, reducing installation cost and bill of materials considerably. 4× fewer inverters needed.

Electrolytic-capacitor-free design

Power electronics designed without the part that fails first, the electrolytic capacitor, to match the true lifetime of PV panels. 25-year design life.

Dual-mode operation

Dual-mode operation can power suitable local loads during grid outages while solar power is available, without a battery. Grid-independence ready.

Prove it · interactive

Drag a cloud. Watch the difference.

A conventional string inverter wires panels in series: shade one, and the whole string drops to the weakest panel. The Quad tracks each panel independently. Try it.

Quad2 · single-phase

Four panels. One unit. Twenty-five years.

The flagship residential microinverter: independent MPPT on four DC inputs, all-AC cabling, dual-mode operation, and no electrolytic capacitors anywhere inside.

For homeowners For installers The product

Quad3 · three-phase

The ease of a microinverter, at commercial scale.

Native three-phase output and 500 W/kg (2000 W AC from a 4 kg unit), for rooftops, carports and industrial arrays. It keeps producing and powers critical loads when the grid drops.

Every panel, watched. Every watt, accounted for.

The gateway commissions the array and syncs the layout to the cloud. The web dashboard watches every panel. The app puts it in your pocket and pushes an alert before you'd notice.

Built for the life of the array

No electrolytic capacitors. No weak link.

Sparq microinverters are engineered to match the true lifetime of the panels they power, through cloud, heat, and twenty-five years of weather.

The digital ecosystem

Gateway. Dashboard. Pocket.

Behind every Sparq array is a connected stack (gateway, web monitoring and mobile) reporting panel-level performance to the cloud.

SparqLinq

Gateway for commissioning, control, and cloud sync.

Web monitoring

SparqVu

Web monitoring with intuitive displays: production, history and health at panel level.

Mobile

Engineered in Kingston. Made in India.

Two continents, one microinverter

Designed in Kingston, Ontario, with roots in Queen's University's ePOWER lab. Manufactured by IL JIN Electronics under the Make in India program, in commercial production since 2025. A March 2026 purchase order for 30,000 Quad2 units (about 60 MW) was expanded to C$32 million in May 2026.
