Why is the Hoymiles HMS 800W 2T the ideal solution for balcony power plants?

Article published at: Jan 24, 2026

The Hoymiles HMS 800W 2T microinverter offers an efficient way to produce solar energy with an output power of up to 800 watts. Integrated WiFi enables real-time monitoring via the S-Miles Cloud, making it particularly attractive for tenants and homeowners who want a simple and effective solution. DRBO Greenenergy provides this inverter as part of an innovative balcony power plant solution.

What is the current state of the solar industry?

The balcony power plant market in Germany is growing rapidly. In 2024, over 1.5 million units were installed, an increase of 300 percent compared to 2023. According to the Federal Network Agency, the registered capacity rose to 1.4 GW. Despite this growth, many households have untapped solar potential on their roofs or balconies, which is not used for electricity generation due to inefficient systems. At the same time, electricity prices are increasing, which intensifies the pressure on households.

What challenges are there in the energy transition?

Many households pay high electricity costs annually, while solar potential lies fallow. Another problem is the high installation costs for conventional solar systems, which often exceed 5,000 euros and deter 60 percent of tenants. Data from the German Energy Agency (dena) show that 40 percent of solar systems achieve less than 80 percent efficiency due to shading. In addition, 50 percent of users do not have remote monitoring, which can lead to failures. However, DRBO Greenenergy offers plug-and-play solutions that address these problems and enable easier handling.

Why do traditional solutions often fail?

String inverters, used in conventional solar systems, lose up to 50 percent efficiency with partial shading. They also often weigh more than 10 kg and require complex roof mounting, making them unsuitable for balconies. The efficiency is usually 90-92 percent, while modern microinverters like the Hoymiles HMS 800W 2T achieve an efficiency of 96.7 percent. Remote monitoring also has to be purchased separately for traditional systems, incurring additional costs.

What makes the Hoymiles HMS 800W 2T the best choice?

The Hoymiles HMS 800W 2T microinverter is a compact, powerful 2-in-1 inverter for two solar modules. With a maximum voltage of 65 V and IP67 protection, it operates reliably at extreme temperatures. It has two independent MPPT trackers, which ensure high efficiency and shade tolerance. Integrated WiFi enables easy monitoring of energy production via the S-Miles Cloud, leading to an efficiency of 96.7 percent. Weighing only 3.2 kg, the inverter is light and easy to install. DRBO Greenenergy also offers the necessary accessories for quick installation.

Who benefits from the Hoymiles HMS 800W 2T in practice?

Scenario 1: Tenant with a shaded balcony
Due to varying shade, up to 40 percent of energy can be lost. The Hoymiles HMS 800W 2T helps compensate for these losses and enables savings of up to 260 euros per year.

Scenario 2: Family with high summer consumption
In summer, air conditioning can consume a lot of electricity. With the Hoymiles HMS 800W 2T, up to 75 percent of electricity can be generated independently, leading to savings of 200 euros annually.

Scenario 3: Small business
For small businesses with high electricity costs, the Hoymiles HMS 800W 2T is a cost-effective solution that leads to a 15 percent reduction in costs.

Scenario 4: Senior apartment
For seniors looking for a simple solution, the Hoymiles HMS 800W 2T offers a maintenance-free and user-friendly way to generate their own electricity.

Why is now the right time to get started?

The balcony solar market is growing rapidly and is expected to reach 5 GW by 2030. The amendment to the Renewable Energy Sources Act (EEG) significantly improves the conditions for balcony power plants, making entry particularly attractive now. With the support of DRBO Greenenergy, you can actively shape the energy transition and benefit from falling prices.
