Enphase Microinverters: An Independent Overview by Solar Choice

Overview of Enphase Energy – Company History

Enphase Energy was based in March 2006 by Raghu Belur and Martin Fornage in California, United States. Enphase was the world’s first microinverter producer, introducing the primary microinverter system in June 2008. It didn’t take Enphase lengthy to determine themselves within the solar inverter market, as by September 2011 Enphase had shipped 1 million inverters.

In 2012, Enphase entered the Australian market and launched on the NASDAQ. Enphase has a dedication to innovation, because it’s one of many firm’s core values. In 2016 Enphase opened a brand new analysis and growth facility in New Zealand. Enphase’s R&D improvements have resulted in 134 patents globally.

Enphase in June of 2018 first introduced the seventh technology of their microinverter expertise, the Enphase IQ Microinverter System. The IQ 7 vary is Enphase’s newest microinverter expertise obtainable.

Enphase’s Australian head workplace is positioned in Melbourne, Victoria.


A Brief Rundown on Solar Inverters

A solar system’s inverter is the purpose at which the DC electrical energy produced by solar panels is was grid-compatible AC electrical energy. There are 4 sorts of solar inverters, these being string inverters, hybrid inverters, microinverters, and power optimisers.


How Do Microinverters Work?

Conventional techniques have only one centralised inverter for your complete solar panel array, microinverter techniques couple a microinverter with every solar panel. Systems that use microinverters have quite a few potential benefits over standard techniques by way of system design flexibility, ease of set up, set up prices, and system power yields. Accordingly, such techniques are rising in reputation, numbers, and affordability.

Some of the final benefits of a microinverter system over a standard system embody:

-Greater system power yields, particularly in circumstances of partial shading of the solar panel array in comparison with standard techniques which have ‘strings’ of solar panels

-Remove doubtlessly extra harmful outgoing high-voltage DC electrical energy related to standard solar photovoltaic (PV) techniques

-Individual solar panel power manufacturing will be monitored intimately–better peace of thoughts for system house owners and better ease in troubleshooting within the occasion of an issue

Microinverters may also be built-in into solar panels themselves as a substitute of connected to mounting (a “detached” association). Installation of techniques which can be comprised of those “AC solar modules” are significantly extra straight-forward than the panel + microinverter set-up.


What is PV Evolution Labs Top Performer?

PV Evolution Labs (PVEL) with assist from DNV GL has been independently testing Solar Panel reliability since 2014, and for the first time in 2019 have examined solar inverters. It is a voluntary check which producers should pay to be part of.  The solar panel testing is taken into account internationally as a wonderful indication of solar panel high quality. It’s anticipated that the inverter testing could have the identical recognition. To learn the complete PVEL scorecard click on right here.

Enphase didn’t rank in any of those checks.


Enphase Inverters – Points of Difference

Enphase continues to show why they’re thought of because the trade’s main microinverter producer. They have achieved this via the fixed innovation of their IQ vary, creating a confirmed observe file.

The Enphase IQ 7 Series is the seventh technology of the product sequence to be launched up to now 10 years. This high-quality vary of microinverters has a low failure fee together with the trade’s highest microinverter EU Efficiency of 96.5%. The Enphase IQ 7 Series Microinverters had been proven to supply 1-3.1% extra energy than string inverters in an impartial examine carried out by PV Evolution Labs.

Enphase goals to make sure that it supplies end-users with a product that not solely guarantees the generic advantages of a microinverter system, but additionally a extra interactive and informative person expertise than most standard techniques particular to Enphase’s applied sciences.

Enphase Envoy & Enlighten

Envoy is Enphase’s home energy answer; that is the software program that connects the person to their solar system. It supplies bi-direction communication between the microinverters and the web.

Enphase Enlighten allows the person to watch their system’s well being and microinverter efficiency at a person solar module degree, via a web site platform and cellular software.


Enphase Inverter Costs

Indicative pricing

Enphase IQ Series Micros IQ7+ 290VA Microinverter $140 to $160
Enphase IQ Series Micros IQ7 240VA Microinverter $120 to $140

Keep in thoughts that inverter prices typically solely run between 10-20% of your whole system, so usually it’s value investing in a high-quality inverter given this can have a big impression on the effectivity and efficiency of your Solar Power mission.

Enphase Microinverter Battery Compatibility

The solely vital limitation of Enphase Microinverters is in regard to battery storage. Microinverters aren’t appropriate with the vast majority of solar batteries as they’re DC coupled, that is due to microinverters output AC power.

However, Enphase Microinverters are in a position to be utilised with the favored AC batteries, the Tesla Powerwall 2, and the sonnenBatterie hybrid 9.53. Enphase additionally provides a CEC authorised battery, the AC Battery is exclusive within the Australian market in that it is extremely small and fully modular: A single unit (weighing 23kg) shops 1.2kWh of usable energy.

The AC Battery is certainly a battery for grid-connected solar techniques: it’s not able to offering backup power within the occasion of a blackout and isn’t applicable for off-grid solar techniques.


A Full Range of Enphase Microinverters Available in Australia 

All of Enphase’s Micro Inverters listed on their Australian web site are authorised by the Clean Energy Council for the Small-scale Renewable Energy Scheme, which is Australia’s home solar rebate program.

The 4 authorised fashions are:

Enphase IQ 7A Microinverter

Enphase IQ 7 Microinverter

Enphase IQ 7+ Microinverter

Enphase IQ 7X Microinverter

Example of an Enphase Commercial Solar Project 

This industrial mission noticed a solar system put in on the Richmond Football Club’s headquarters and coaching facility; the ME Bank Centre which is positioned in Melbourne. The system put in by Metro Solar totaled 100kW in measurement. The system used Enphase M215 Microinverters and Yingli 250W Solar Modules.

Utilising Enphase expertise, Metro Solar was in a position to design a system to seize most harvest and improve efficiency for the ability’s extraordinarily giant baseload, most of which is consumed throughout the day. The microinverters additionally enable further technology within the morning and at nightfall to extend general financial savings for the Richmond Football Club.
