Inverter Type

Specification
Updated 2026-08-24 · Read this page as Markdown

The architectural class of the unit: string inverter, microinverter, hybrid or off-grid. The type determines where it sits in the system, what it can be connected to, and whether it can work without a grid present.

A string inverter converts a whole series-connected group of modules at one point and is the default for most roofs. A microinverter sits under each module and converts locally. A hybrid inverter adds a battery port and energy management to a grid-tied design. An off-grid inverter forms its own AC network and cannot export. The distinction is not cosmetic: a plain grid-tied string inverter shuts down in a power cut by design, so if backup is the goal, the type has to be chosen accordingly rather than bolted on later.

Hybrid Inverter A grid-tied inverter that also has a battery port and the control logic to charge and discharge storage, deciding moment by moment whether solar energy goes to the loads, to the battery or to the grid. Many hybrids can additionally supply a protected circuit during an outage. Microinverter A small inverter mounted behind an individual solar module that converts that module's DC output directly to grid-frequency AC. Modules are then connected in parallel on an AC trunk cable instead of being wired into a DC string. Number of Phases Whether the inverter delivers single-phase or three-phase alternating current on its output. It must match the building's supply, and above a certain power level the network operator normally requires three-phase connection. Off-Grid Inverter An inverter that creates its own AC network from a battery bank rather than following an existing grid, supplying loads in an installation with no utility connection. It is also called a standalone or battery-based inverter. Transformerless Inverter An inverter that converts DC to AC without a galvanic isolation transformer between the array and the grid. Removing the transformer raises efficiency and cuts weight and size, and it is the dominant design in modern residential equipment.
