About APsystems
Founded in 2010 in Silicon Valley, USA, APsystems manufactures its microinverters in Jiaxing, China. The company specializes in multi-module microinverters equipped with more than one Maximum Power Point (MPP) tracker. With over 1 GW of installed inverter capacity worldwide, APsystems has established itself as a leading name in the solar industry.
APsystems inverters are designed to work seamlessly with modern high-performance PV modules. A key feature is their ability to support high input currents per module—up to 550 Wp—making them ideal for applications like balcony power plants. This forward-thinking design keeps pace with the growing trend of higher-power solar modules, ensuring compatibility with future PV technologies.
Legal Considerations for Balcony Power Plants (Germany)
In Germany, balcony solar systems are limited to 600 watts on the AC side. These systems must be registered with both the national market data registry and the local grid operator. However, regulations are evolving, and the German government may soon increase the AC limit to 800 watts, as already seen in Austria.
Power from balcony systems is typically fed into the household grid using a Wieland feed-in socket, though Schuko plugs are also permitted. Installation is allowed in both private homes and rental apartments. In multi-family buildings, tenants must obtain consent from the property owner and the condominium association before installation.
How APsystems Microinverters Work
APsystems’ single-phase microinverters operate at 230 V and feature an IP67 protection rating, making them suitable for outdoor installation. These compact inverters are mounted directly on the back of PV modules and connect on the DC side via integrated MPP trackers. The generated power is then transferred to the home grid using either a Wieland or Schuko plug.
With an optional energy communication unit, users can monitor real-time energy production through a dedicated app. Electricity generated is used directly by household appliances, and any surplus is fed into the grid.
Key Benefits of APsystems Inverters
- Durability: Backed by a 12-year warranty, APsystems inverters offer long-term reliability. (Full warranty applies when paired with a smart monitoring interface.)
- High Performance: With support for high input currents (up to 18 A), these inverters can maximize output—reaching the 600 W AC cap even with newer, high-output PV modules.
Available Packages via Memodo Onlineshop
We offer a complete package designed for two PV modules. It includes:
- One APsystems inverter with two MPP trackers
- A 4-meter AC cable with open ends
- An energy communication unit
You can choose between a Schuko plug or Wieland feed-in socket depending on your specific installation needs.
Ideal Applications
APsystems inverters are well-suited for:
- Balcony power plants
- PV modules mounted on exterior facades (e.g., under windows)
- Garden house roof installations
How APsystems Stands Out
Compared to other microinverter brands, APsystems offers a significantly higher input current capacity (up to 18 A), ensuring compatibility with next-generation PV modules. As demand for balcony solar solutions grows, APsystems continues to lead the way with inverters designed to meet modern energy needs.
