Hoymiles products for grid-connected PV systems and balcony power plants

PVundSO offers a comprehensive selection of Hoymiles products for decentralized power generation. The Chinese manufacturer Hoymiles specializes in microinverters and battery storage systems and is one of the world's leading providers in this segment. Their product range includes solutions for balcony power plants starting at 400 watts, up to professional PV systems with several kilowatts of power. All Hoymiles components available from PVundSO comply with VDE standards and have the necessary certifications for the German market.

The product range extends from compact microinverters in the HMS series and three-phase models in the HMT series to hybrid inverters in the HIT series with integrated battery connection. The range is complemented by suitable accessories such as connection cables, DTU units for monitoring, and specially developed connectors. At PVundSO, you benefit from free shipping within Germany and a delivery time of 2 to 8 business days, depending on product availability. Hoymiles inverters are characterized by their modular design, which offers significant advantages during expansions or maintenance work.

Hoymiles inverters for your photovoltaic system

Hoymiles inverters operate on the principle of modular power optimization, where each solar module has its own microinverter. This architecture prevents power losses due to shading or different module orientations, as each Hoymiles microinverter operates its own individual Maximum Power Point Tracking (MPPT). The HMS series is suitable for single-phase connections and offers models with output power from 400 to 2000 watts. For three-phase installations, HMT models with up to 2250 watts are available.

A key advantage of Hoymiles microinverters lies in their safety. The DC voltage is converted directly to AC voltage at the module, eliminating the need for dangerous high-voltage cables running through the building. Current models achieve an efficiency of up to 96,7%. The HMS-500-1T, for example, handles 500 watts of input power at a maximum DC voltage of 60 volts and offers two MPPT inputs for flexible module configurations. System performance can be monitored in real time using the included or separately available DTU-WLite-S. Hoymiles inverters contribute to system safety by automatically shutting down immediately in the event of a power outage.

Buy a Hoymiles balcony power plant at a great price and reduce your energy costs

A Hoymiles balcony power plant offers renters and homeowners an easy way to get started with solar energy. PVundSO offers complete sets starting at €249, including all necessary components. The CLASSIC balcony power plant, with two solar panels and 840 watts of module power, uses a Hoymiles HMS-800-2T inverter and generates 700 to 900 kWh of electricity per year, depending on location. At an average electricity price of €0,40 per kWh, this equates to annual savings of €280 to €360.

The payback period for a Hoymiles balcony power plant is typically between 3 and 4 years. The MAXI balcony power plant, with four modules and a total output of 1680 watts, delivers correspondingly higher yields and is suitable for households with increased electricity consumption. Since January 2024, balcony power plants with an output of up to 800 watts can be connected in Germany without an electrician. Installation is carried out using a standard Schuko socket, although registration with the grid operator and in the market master data register is required. The Hoymiles balcony power plant inverter switches on automatically when the sun is shining and immediately reduces the electricity drawn from the grid. Excess electricity is fed into the public grid without compensation.

Hoymiles microinverters for reliable solar power generation

Hoymiles microinverters offer significant advantages over string inverters due to their decentralized design. Each solar module operates independently, so shading, soiling, or defects in individual modules do not affect the overall performance. A defective Hoymiles microinverter only affects a single module, whereas in string systems, the entire module chain can fail. The MTBF (Mean Time Between Failures) of Hoymiles microinverters exceeds 100.000 operating hours, which corresponds to a lifespan of more than 25 years.

The HMS-2000-4T processes up to four solar modules, each with a maximum input power of 600 watts. Integrated off-grid protection ensures that the inverter shuts down within 0,2 seconds in the event of a power outage. Active cooling via a fanless heat sink design ensures silent operation and minimizes wear parts. Hoymiles microinverters operate in a temperature range of -40 to +65 degrees Celsius, making them suitable for extreme climates. The IP67 protection rating allows for outdoor installation without additional weatherproofing. Wiring is tool-free and takes only a few minutes using Hoymiles connection cables with pre-assembled connectors.

Hoymiles battery storage systems to optimize your self-consumption

Hoymiles battery storage systems expand your photovoltaic system by adding energy storage capabilities and increasing your self-consumption rate to up to 80%. The MAXI balcony power plant with storage combines four 1680-watt solar modules with a 2,56 kWh battery system. The integrated Hoymiles battery storage system charges during the day with excess solar power and supplies your base load in the evenings and at night. Typical base loads such as refrigerators, routers, and standby devices require a constant 100 to 300 watts, which can be covered by the stored energy.

Hoymiles' HIT series hybrid inverters manage both solar panels and battery storage via a central control unit. Models ranging from 10 to 20 kW are suitable for larger residential buildings or commercial applications. The three-phase design ensures even load distribution within the home's electrical system. Battery management systems continuously monitor cell voltage, temperature, and state of charge to maximize battery lifespan. Lithium iron phosphate batteries achieve 6000 to 8000 charge cycles at a 90% depth of discharge. With daily use, this equates to an operating life of 15 to 20 years. In the event of a power outage, the emergency power function keeps critical appliances running for several hours, depending on the battery's state of charge and the connected load.

Frequently asked questions about Hoymiles

What warranty does Hoymiles offer on inverters?

Hoymiles offers a 12-year manufacturer's warranty on microinverters, which can be optionally extended to up to 25 years. Battery storage systems come standard with a 10-year warranty. The warranty covers defects in materials and workmanship, but requires professional installation in accordance with VDE standards.

Can I combine multiple Hoymiles inverters?

Yes, Hoymiles microinverters can be combined and expanded as needed. Multiple HMS devices are connected in series via the T-node system and linked to a DTU unit. The DTU-WLite-S monitors up to 99 inverters simultaneously, enabling systems up to 50 kWp.

Do I need an electrician for the installation?

Balcony solar power systems with an output of up to 800 watts can be connected yourself using a standard household socket. For permanently installed PV systems and battery storage, installation by a certified electrician is legally required. PVundSO can connect you with qualified installation partners in your region upon request.
