Hoymiles – Your Partner for Smart Energy Solutions, Specializing in Module-Level Power Electronics Technology


Solar contractors face many decisions when it comes to finding the best solar design. One important consideration is determining whether to use module-level power electronics (microinverters or DC optimizers). Once costly specialty products, module-level power electronics (MLPE) have made great strides in the last decade and are rapidly growing in popularity. And there’s a good reason for that. Incorporating these devices can offer a number of design benefits. One of the primary reasons is to improve the energy production of the system. MLPE can help mitigate production losses from a variety of different factors such as shading, module mismatch losses, and orientation mismatch losses and provides compliance with NEC module-level rapid shutdown requirements.

Hoymiles is a global MLPE (Module Level Power Electronics) solution provider, specializing in module-level inverters (microinverters) and storage systems. With a vision of a clean, sustainable future, they strive to lead the smart energy industry through their rugged technology and reliable products. With their driven engineer team, 500+ global experts and distribution & service network spanning North America, South America, Europe, Asia, Africa and Oceania, Hoymiles has empowered homeowners and professionals in more than 70 countries and regions to join the journey to true open energy. Now they are favored by the market as a trustworthy partner to their investors, installers and end consumers.

Offering Industry-Leading MLPE Solutions and Services

Microinverters: When it comes to solar, your panels are just part of the picture. Microinverters perform the critical task of turning raw energy into safe, usable electricity. But this process always creates some amount of waste – electricity you’re creating, but not able to use. When you choose Hoymiles, you get industry-leading efficiency, low failure rates and premium quality. So you can get more from your installation and accelerate your journey to open energy. Hoymiles microinverters are built to plug-and-play, ready to get your solar ecosystem up and running sooner. Configure your microinverters to match your installation and solar panel layout. Hoymiles microinverters come with low failure rates and built-in surge protection. With 99.8 percent MPPT efficiency ratings, more of your panel production is turned into usable energy.

Solar Energy Storage: A hybrid inverter increases your self-consumption rate by turning excess energy you don’t use into a suitable form for battery storage. This can then be used at night or when your solar installation doesn’t generate enough energy to meet demand from your appliances. Energy storage also means you can balance your grid energy around peak and off-peak times, reducing your energy costs. Finally, solar batteries are a great source of backup power that’s there whenever you need it.  Solar battery pricing varies widely depending on capacity and performance – your installer can help you find the right solar battery for your needs. Their HY3-series hybrid inverters give you a way to store surplus solar energy in a battery storage system, then use it however and whenever you want, day or night. As a result, you can increase your self-sufficiency to more than 80 percent, reducing your energy bill while creating an always-available source of backup power. It’s an effective way to make sure that clean, free energy is always available – even at night or during power outages.

Rapid Shutdown Device: Even when the power is cut, residual energy is a major hazard to anyone working with your string inverter installation – from maintenance teams to firefighters. The rapid shutdown device automatically reduces voltages to safe levels when power is interrupted. It’s fast, simple, and compliant with robust standards like NEC 2017/2020 and SunSpec. It brings module-level monitoring to your solar installation. It’s an extremely convenient way to track performance in real time, right down to individual components and solar panels. There’s no need to physically check panels on site to find the cause of performance problems. Just remotely monitor your individual panels and get up-to-the-minute data. Designed for compatibility, their rapid shutdown devices can de-energize even the most powerful panels. Whatever the size of your implementation, they will help you maximize safety. Hoymiles rapid shutdown devices aren’t just for Hoymiles inverters. They support connectivity with inverters from every leading manufacturer, so you can make any installation safe and compliant.
