Micro Inverters

Maximum energy yield through solar microinverters

Solar microinverters operate on a fundamentally different principle than conventional string inverters, enabling significantly higher energy yields in complex installation situations. While in string systems the power output of all modules is limited by the weakest link, a microinverter optimizes each solar module individually. This module-based MPPT technology continuously adapts the power conversion to the specific conditions of each individual panel.

The decisive advantage becomes apparent when dealing with shading, different module orientations, or soiling. High-quality microinverters compensate for these factors by maximizing the yield of each module individually. Practical measurements show yield increases of 8 to 15% compared to string systems on partially shaded roofs. PV microinverters truly unleash their full potential, especially with balcony power plants with up to 800 watts of feed-in power or with complex roof geometries featuring dormers and chimneys. The integrated module monitoring also provides detailed performance data for each panel and enables rapid fault identification.

Buy microinverters for optimal energy independence

Anyone looking to buy a microinverter is investing in a flexible system with significant safety advantages. Because the conversion of direct current to alternating current takes place directly at the module, no dangerous DC voltages above 60 volts are generated on the roof. This significantly reduces the risk of fire and greatly simplifies both installation and maintenance. Installers do not require special high-voltage training, which lowers installation costs.

The modular design allows for gradual system expansion without complex planning. You can start with two modules and one microinverter and easily add more units later. Each added microinverter operates independently, without affecting the overall system configuration. This scalability makes the technology particularly attractive for households with limited initial budgets. At PVundSO, you receive equipment from leading manufacturers with warranties of 10 to 15 years, designed for long-term system reliability.

PV microinverters with WLAN monitoring for every need

Modern PV microinverters integrate Wi-Fi functionality for real-time monitoring of system performance. Smartphone apps allow you to monitor the energy production of each individual module and immediately detect any performance losses. This granular monitoring level is not achievable with string inverters, as they only record total yields. The monitoring systems visualize daily, weekly, and annual yields and enable in-depth analyses of system efficiency.

PV micro inverters with integrated communication technology significantly simplify commissioning. Plug-and-play installation requires only wiring the modules to the inverters and connecting them to the home's electrical grid. Firmware updates are performed wirelessly via the cloud connection, ensuring the devices are always up to date. In case of malfunctions, the system sends automatic notifications to your smartphone. Data is stored for several years, enabling detailed yield forecasts and profitability calculations. For systems with multiple inverters, the central monitoring platform provides a clear overview.

Cleverly utilize shaded roofs with microinverters

Shaded roofs pose a significant challenge for string inverters, while microinverters handle this situation optimally. Trees, neighboring buildings, satellite dishes, or antennas cast shifting shadows that reduce the output of the entire module chain in string systems. Installing each module individually, with its own microinverter, completely eliminates this domino effect. Each panel produces its maximum possible yield, regardless of the conditions of neighboring modules.

This is particularly advantageous for complex roofscapes with multiple orientations. East-west installations, where modules face different directions, benefit significantly from individual module optimization. Each unit automatically compensates for varying angles and intensities of sunlight. Even with temporary shading from falling leaves, snow, or bird droppings, unaffected modules continue to operate at full capacity. The technology is ideally suited for garages, carports, and garden sheds with less than ideal installation conditions. Even with permanent partial shading of 20 to 30% of the surface area, the system still achieves economical yields.

Individual consultation to find the right microinverter for you

Selecting the right microinverter system requires considering several technical parameters. The device's maximum input power must match the nominal power of your solar modules, with an oversizing factor of 1,2 to 1,3 being recommended. For example, modules with a nominal power of 400 watts require inverters with a capacity of at least 480 to 520 watts. The input voltage ranges must be compatible with the module specifications to ensure optimal MPPT performance.
