Kits matched to panel wattage
Microinverters are sourced matched to the specific module wattage and voltage window in a project, since an undersized microinverter caps a panel's output before it ever reaches the roof.

Microinverter kits matched to your panels
Built-in rapid-shutdown compliance
Module-level shutdown is inherent to a microinverter architecture, which satisfies NEC 690.12 without the additional rapid-shutdown devices a string inverter system needs.
Module-level monitoring included
Per-panel production data comes standard with most microinverter systems, giving a crew shading and fault diagnostics a string-level system can't match.
Right-sized kits, simpler shutdown
Stop over- or under-sizing microinverters
Wattage and voltage compatibility gets checked against the specific panel before the kit ships.
Simplify the rapid-shutdown BOS list
Module-level shutdown covers the NEC 690.12 requirement without extra shutdown devices.
FAQs
Why do microinverters simplify NEC rapid-shutdown compliance?
Microinverters convert DC to AC at each module, so the high-voltage DC that rapid shutdown targets never runs across the roof. That means module-level shutdown is inherent to the architecture rather than added through separate rapid-shutdown devices and initiators. The result is a shorter balance-of-system list and fewer components to coordinate for compliance.
How are microinverter kits matched to panel wattage?
Each microinverter has an input power and current window, and the paired module's wattage and operating current should fall inside it. A microinverter sized well below panel output clips production in peak sun, while one sized far above it wastes cost and headroom. Kits are assembled so the microinverter model corresponds to the module's wattage class and current, which is why matching by panel spec avoids over- or under-sizing.
What's the trade-off between microinverters and a string inverter with optimizers?
Both deliver module-level power electronics and rapid-shutdown compliance, but they distribute the hardware differently. Microinverters put a full inverter at every module, simplifying design and monitoring but adding per-module cost and more rooftop electronics; a string inverter with optimizers centralizes conversion, which can lower cost on larger or simpler roofs while adding a single point to service. Roof complexity, shading, and array size usually decide which fits.
