How does grid feed-in work?

Grid feed-in is a process in which the electricity generated by the solar module and a suitable inverter is fed directly into the public power grid. The inverter is ideally installed near the solar modules and connected to them using a solar connector. Regardless of system size, the solar installation must be registered with the national market master data register in accordance with legal requirements.

The complete system includes:

• 10x Luxen Solar 450W Bifacial Solar Module TopCon Luxneri Series N5 Full Black
• 1x Growatt MIC 3000TL-X String Inverter PV 3000W Single-Phase
• 1x Growatt SPM-E Electricity Meter Single-Phase 100A Smart Meter
• 1x Growatt Shine-WiLan-X2 Data Logger
• 3x MC4 Connector Pair - Female + Male 4-6mm² Type 4 PV-KBT4/6I
• 1x 10m H07RN-F 3 G 1.5mm High-End Rubber Cable Lapp Cable 1600103
• 1x 30m Lapp Solar Cable H1Z2Z2-K 1X6 WH/BK

Custom Options: The complete system can optionally be offered with a 3-phase current sensor. Other customizations regarding the number and selection of modules are also possible. Our support team is happy to help you with that.

Why a string inverter: The performance of solar modules varies due to temperature, sunlight, and shading, which can lead to so-called mismatch losses. These losses occur when one panel in a series performs worse, reducing the output of the entire string. A string inverter helps reduce these losses.
Maximum Power Point Tracking: MPPT technology generates the best possible output from your solar system. The MIC inverter’s MPPT adjusts the optimal balance between voltage and current depending on sunlight and temperature throughout the day. The wide MPPT voltage range supports the connection of many solar modules and enables efficient energy yield, especially when the sky is partially cloudy and light intensity is fluctuating.
Flexible and simple installation: Thanks to compact dimensions and light weight, the inverter is quick and easy to mount. Integrated MC4 connectors make connecting from solar modules to the inverter fast. Multiple protection functions ensure safe and smooth operation.
