One of the most important criteria for PV inverters is the efficiency. The higher the efficiency, the lower the losses that are produced when converting DC current from the solar modules into AC current for the grid. SMA has set a new record for transformer-based units by achieving a maximum efficiency of 95.6%.
Additionally the OptiCool system developed by SMA in a sturdy aluminium housing with a double-chamber design safely protects the electronic components from dust and water for long term performance of your inverter.

Key Features:

• Best efficiency for transformer inverters in the 4kW class
• OptiCool - Maximum power up to an ambient temperature of 45°C due to dual compartment colling system
• SMA grid guard 2: Automatic disconnection
• Flexible application
