M190 Microinverter

The Enphase Microinverter shifts DC to AC conversion from a large, centralized inverter to a compact unit attached directly to each solar module in the power system.  Distributing the conversion process to each module makes the entire solar power system more productive, reliable, smarter and safer than traditional inverter systems.

Solar Power Challenges

Solar power production is affected by various factors such as module mis-match, obstruction shading, inter-row shading, and obstacles such as dust or debris.  In addition, non-uniform changes in temperature, irradiance, and shading create complex current-voltage curves, further affecting energy harvest.  This is due to the fact that in traditional systems the performance of the entire system is dictated by the performance of the weakest module.

The Enphase Solution

The Enphase Energy Microinverter System solves solar power challenges by performing Maximum Power Point Tracking (MPPT) at each solar module.  MPPT is an algorithm used to calculate and respond to temperature and light changes detected on a solar power system, and to determine how much power to draw from the module.  In contrast, centralized inverter’s MPPT algorithm sees the entire solar power system as a single module, and responds to the lowest production numbers it detects.

Increased Productivity

The Enphase MPPT algorithm works at each solar module in an installation and achieves greater than 99.6% accuracy which enables it to maximize energy harvest at all times, even during variable light conditions.  Tests show systems using Enphase Microinverters increase energy harvest by as much as 25% over systems using traditional inverters.

More Reliable

Traditional centralized inverters implementations create a single point of failure for solar power systems.  If the inverter fails, the entire system is disabled. Enphase Microinverters convert power independently at each solar module.  If one microinverter fails, the rest continue to operate as usual.  Also, if a microinverter is damaged or fails, it can be replaced during routine maintenance or when convenient, further reducing maintenance costs.

Reduced Operational Costs

With the Enphase Microinverter System, installers are no longer limited by string design, marginal designs, co-planarity, and matched modules.  The space, heat, and noise associated with a large inverter are eliminated.  Enphase Microinverter Systems improve mechanical integration, reduce wiring time, and remove the need for DC switching points.

Flexibility

Another benefit of the distributed microinverter design is the potential for installations to be expanded over time.  An initial set of solar modules can be installed and additional modules added as needs and budgets grow without requiring the replacement of a large centralized inverter.

Compliance and Reliability

The Enphase Microinverter is CSA Listed per UL1741 and can withstand surges of up to 6kV.  Enphase Microinverter Systems undergo rigorous testing including HALT and HASS, ensuring reliability.  Independent testing by Relex – a leading third party reliability expert – has shown an estimated Mean Time Between Failure (MTBF) of 331 years for Enphase Microinverters.

The Enphase Microinverter works in conjunction with the Envoy communications gateway and the Enlighten website.

D380 Microinverter

The D380 “TwinPack” Microinverter is comprised of two Enphase Microinverters in a single enclosure and an innovative cabling system, designed to reduce Balance-of-System costs and installation time. The D380 has a black anodized housing which improves aesthetics and allows for better thermal dissipation. The D380 TwinPack is optimized for commercial installations, but it is applicable to both commercial and residential installations.

Benefits

The D380's "two-in-one" enclosure cuts in half the number of microinverter units needed for an installation. In addition, the D380's new cabling system reduces the number of interconnections and junction boxes by 33%.

New Cabling System

The D380 utilizes an innovative "trunk and drop" cabling system. This new approach makes it even easier to connect microinverter units, and the 12 AWG trunk cable increases current capacity, allowing for 20A branch circuits. This means that you can have more modules per branch circuit:
