Solar Micro-Inverter technology by:

Enphase Energy Micro-Inverters are revolutionizing the solar industry across the spectrum of residential, commerical,and utility scale projects, and in many cases have replaced the competing technology of central inverters. Micro-Inverter technology is robust, proven and extremely cost e�ective. Enphase Micro-Inverters o�er the following inherent advantages that are unmatched by all other competing inverter technologies:

Enhanced Power Harvest:Each micro-inverter integrates with its own solar panel. This allows each solar panel to produce power independently from every other solar panel. This dynamic is extremely valu-able to maximize or “harvest” the most energy possible from the entire system. Regardless of sunlight condition, dirt or debris collected on the solar panel or any transient shading conditions, micro-inverters allow each solar panel to maximize its production threshold independent from every other solar panel in the system. The competing technology of a centrally inverted system is not engineered to support solar panels performing independently, resulting in a dramatically lower energy harvest assigned to the entire system. This is character-ized as Maximum Power Point Tracking, or MPPT (the optimization of volts and amps).

Ensured System Reliability:Each Micro-Inverter pairs with its own, individual solar panel. In the unlikely event of a single solar panel failing, the failure would be limited only to that panel. The rest of the panels in the system would continue functioning una�ected, guaranteeing maximum system reliability andproduction. In a centrally inverted system, an entire system would be a�ected until the failed panel could be located and replaced.

Lower Voltage, Safer Installation:Micro-inverters install directly under each solar panel and immediately convert the panel’s DC electric production into AC electricity used in your facility. The result is a 240 Volt micro-inverted system, instead of a 600 Volt system as rendered by a central inverter.

“Enlighten” System Monitoring:

Proactive Customer Service – Enlighten continuously communicates with all solar panels in the system and runs constant performance tests. If a problem with any solar panel or microinverter in the system is detected, Enlighten sends an alert to the system installer via email. The alert is a detailed report of the tr-ouble event. This allows the installer to correct the problem, often even before the system owner is aware a problem exists. This is a true measure of proactive customer service and commitment to system up-time and reliability.

Reinforcement of Solar Panel production warranties- Every major manufa-cturer of solar panels o�ers a product workmanship warranty that covers thesolar panel against physical defects for a period of 10 years. In addition to this

workmanship warranty, manufacturers also o�er a “power production” guarantee whereby they warrant their solar panels will produce at least 90% output after 10 years of service and 80% output after 25-years. This type of production warranty is common and linear degradation of the solar panels production is expected during their service life. Enlighten monitor-ing helps owners to enforce any production warranty claims. Because Enlighten displays the individual output of everysolar panel, it allows the system owner to focus on any panels that are performing below their warranty level. This level of monitoring is not possible with a central inverter., where system and output is displayed as a “lump sum”. With a central inverter, neither the system owner nor the system installer would be able to identify underperforming or failing solar panels.

Having a proven track record, Enphase Energy Micro-Inverters are furnish-ed with the manufacture’s 25-year warranty that covers parts and labor (warranty documentation can be found at www.enphase.com/warranty.) The Mean Time Between Failure (MTBF) for Enphase Energy Micro-Inverters is lab tested at an astonishing 119 years. Comparatively, the vast majority of central inverters come with a standard manufacturer warranty of just 10-years, making Enphase Micro-Inverters...

Better Analytics- Having the ability to monitor the productivity of your solarenergy system is important to validate your capital investment. But monito-ring takes on a whole new level with Enphase Micro-Inverters. That’s because Enphase has created an internet based monitoring portal called “Enlighten”. The Enlighten portal allows you as the system owner to have control over system analytics anyplace the internet is available, including your smart phone. Enlighten enables you to measure the output of every solar panel relative to every other solar panel in the system. Enlighten shows a virtualization of thepanels as they are installed on your rooftop and measures solar panel output real time, where system production data is refreshed every �ve minutes. Enlighten is also very intuitive and makes it simple to query performance informa-tion daily, weekly, monthly, annually, and on a lifetime basis for the entire system, select solar panels or just a single solarpanel. The �exibility of the system is amazing and unmatched. System analytics can be referenced numerically and/or graphically in easy to read detailed reports. All data can be directly emailed or exported from Enlighten. Best of all, there are no subscription fees to pay-ever. Enlighten is provided for free from Enphase Energy.
