- Maximizing the energy harvest of an array of solar modules.
- Having a single inverter for an entire array creates a single point of failure.
- Complex design decisions must be made in sizing DC series and parallel strings.
- Limited monitoring and analysis and no per-panel visibility.
Enphase Microinverter General FAQ
What is a Microinverter?
An inverter is a power converter that converts direct current (DC) into alternating current (AC).
Traditionally, this has meant one, centrally-located inverter converting all of the DC current from
entire PV array. A micro-inverter is a much smaller version of the central inverter where there is
per PV module. The DC gets converted to AC at the point of the PV module. AC power then travels
through an ordinary branch circuit, and to the service panel.
What is a Microinverter system?
A Microinverter system is a federation of multiple microinverters all along a branch circuit, and/or
within multiple branch circuits, which are all converting DC to AC, all injecting their current
upstream, and reporting back to Enphase regarding their individual power-production statistics.
innovations allow a microinverter system to include a Lithium-Ion battery for backup power and other
energy storage purposes.
How do Enphase Microinverters differ from AC solar panels?
With AC solar panels (PVAC), the inverter and module are a single unit and are sold and installed as
such. In contrast, the Enphase Microinverter is architected as a standalone inverter. This modular
design means they can offer the flexibility to work with most off-the-shelf solar modules.
Can Microinverters work in off-grid environments?
No. They have only been tested to work in grid-tied installations.
