Table of Contents In November 2023, we introduced our new IQ8 Microinverter, IQ8P-3P™, for the small commercial solar market in North America. The IQ8P-3P Microinverter enables a peak output power of up to 480 W, supporting small three-phase commercial applications and newer, high-powered solar panels. IQ Batteries. Our Enphase IQ Battery storage systems, with usable and scalable capacity of 10.1 kWh and 3.4 kWh for the United States, and 10.5 kWh and 3.5 kWh for Europe and other international countries, are based on our Ensemble OS™ energy system, which powers the world’s first grid-independent microinverter-based storage systems. We currently ship our Enphase IQ Battery storage systems to customers in North America, Belgium, Germany, Austria, France, the Netherlands, Switzerland, Spain, Portugal, Sweden, Denmark, and Greece. Enphase IQ Batteries in Europe can be installed with both single-phase and three-phase third-party solar energy inverters, enabling homeowners to upgrade their existing home solar systems with a residential battery storage solution that reduces costs while providing increased self-reliance. ® In May 2023, we introduced our latest Enphase Energy System, which features the new IQ Battery 5P and IQ8 Microinverters. The IQ Battery 5P is modular with 5 kWh capacity and the IQ8 Microinverters provide a peak output power of 384 W. The IQ Battery 5P is also available for customers in Australia, the United States, Puerto Rico, the United Kingdom, Italy and Australia. The IQ Battery 5P is modular by design and is designed to deliver 3.84 kW continuous power and 7.68 kW peak power, which allows homeowners to start heavy loads like air conditioners easily during power outages. ® Our IQ Load Controller for our Enphase IQ Battery storage systems allow homeowners to decide what gets power in their home in the event of a grid outage, with the ability to choose up to four loads. These loads will be on when the grid is present and shed automatically in the event of a grid failure. This product makes installation simpler and saves time for installers. Electric Vehicle (“EV”) Chargers. The increasing penetration of EVs has implications for home energy management, as households not only consume significantly more power with an EV, but also have a large battery that can be used for both backup and grid service. In the first quarter of 2023, we began production shipments of Enphase branded EV chargers at our existing contract manufacturing facility in Mexico. We expect this move could help to meet the rapidly growing demand for reliable and affordable EV charging solutions by providing a greater supply of product and more predictable lead times. Our EV chargers are compatible with most EVs sold in North America. Customers are able to purchase Enphase-branded EV chargers with a charging power range between 32 amperes and 64 amperes. In January 2023, we demonstrated our bidirectional EV charger technology enabling vehicle-to-home and vehicle-to-grid functionality. This new bidirectional EV charger is designed to leverage the power of grid forming IQ8 Microinverters and Ensemble OS energy management technology to seamlessly integrate into Enphase home energy systems, and can be controlled from the Enphase App, empowering homeowners to make, use, save, and sell their own power. ® In June 2023, we introduced the IQ Energy Router family of devices in Germany and Austria to enable the integration of select third-party EV chargers and heat pumps into Enphase solar and battery systems. The IQ Energy Router family of devices monitors and controls energy usage between an Enphase solar and battery system, EV chargers and heat pumps. The devices work in coordination with the Enphase Energy System and deploy artificial intelligence-based solar production forecasting, consumption forecasting, and an optimization engine to maximize self-consumption. In October 2023, we launched our smart Enphase IQ EV Chargers in the United States and Canada. The IQ EV Charger is Wi-Fi-equipped and includes smart control and monitoring capabilities. The IQ EV Charger is designed to seamlessly integrate into our solar and battery system to help homeowners maximize electricity cost savings by charging directly from solar energy. Grid Services. We participate in the ConnectedSolutions program, which is an incentive program implemented by two utilities in the Northeast region of the United States to reduce electrical demand during high-use periods. Enphase storage customers in Connecticut, Massachusetts and Rhode Island can sign-up, monitor, track money earned and control participation in the program using the Enphase App. We also participate in the Hawaiian Electric’s Battery Bonus grid services program that offers an incentive for homeowners on the island of Oahu to install a new home battery. And we participate in the Arizona Public Service residential battery services program, which offers homeowners who install Enphase IQ Batteries in its service territory the chance to participate and earn money through one-time, upfront incentives.
