Micro Inverter

The principle

Modular design made for easy expansion

When it comes to generating electricity with the micro-inverter system, you can determine how small (or big) your PV system will be (or will be). Depending on your energy needs and your financial resources, the system can be extended or modified panel for panel.
  • System sizes range from a single module (eg a balcony) to a multi-kilowatt peak output
  • can be connected through the flexible design of the Sunny Multigate an unlimited number of additional micro inverters * * Depending on local regulations
The principle

The device

more with less

In the development of the Sunny Boy 240, SMA has focused on the essentials. This means we combined elements, doing away with complete assemblies. As a result, the unit contains approximately 50 percent fewer parts than competitive products.
  • Central functions outsourced to the Sunny Multigate (eg power line communication filters or disconnection device)
  • Central functions outsourced to the Sunny Multigate (eg power line communication filter or disconnection device)
The device


Exceptional easy

Regardless of where and how the device is installed, the electrical and mechanical planning work to a minimum. The installation and connection are extremely easy thanks to the ready-made, easily identifiable plugs.
  • Mounted AC cables
  • Choice of DC adapters


Everything at a glance

Access to the Sunny Portal, which comes as standard, can the system be controlled in a modular level. This means that the PV administrators benefit from round-the-clock access to detailed analysis, diagnosis and yield monitoring functions.
  • Display of the module and inverter data in real-time
  • Clear identification of shading / module problems
  • automatic reporting


Everywhere at home

A micro-inverter system is also ideal for challenging applications with partial shade, a complex roof structure, small systems or different roof orientations.
  • In combination with an existing string inverter system or if a newly installed micro inverter system
  • larger yield with shaded or differently oriented modules
