How does a grid feed work?

Grid feed-in is a process in which the electricity generated is fed directly from the solar module and the appropriate inverter into the public power grid. The inverter is ideally installed close to the solar modules and connected to the solar module with the solar plug connector. Regardless of the size of the system, it is necessary to register the Solarasystem with the market master data register in accordance with the legal requirements.

The complete system includes:

• 8x Longi Hi-Mo-6 425w solar module lr5-54hth Black Frame
• 1x growatt mic 2500tl-x 2.5kW string inverter pv 2500w 1-phase
• 1x growatt spm-e electricity meter 1-phase 100a Smart Meter
• 1x growatt Shine WiFi-X data logger
• 3x MC4 plug pair - socket + plug 4-6mm² type 4 pv-KBT4/6I

Longi lr5-54hth-425M 425w solar module

TheLongi lr5-54hth-425M is a 425w solar module with monocrystalline cells and belongs to the improved Hi-MO 6 product series. The hpbc cell technology uses a full-back welding technology and thus increases the resistance to microcracks.

Compared to the previous series, the Hi-MO 6 series has been improved in terms of performance, reliability, appearance and optimization function. In terms of the appearance of the solar module, the Hi-MO 6 series simplifies the complexity and redefines the aesthetic concept of photovoltaic modules.

about the Longi LR5

• High efficiency hpbc cell technology
• High efficiency of 21.8%
• Improves light absorption by around 2.27
• 3.2mm coated tempered glass
• Manufacturer's product guarantee: 15 years on material and workmanship
• Simple design embodies modern style
• Better performance in energy generation
• High-quality module ensures long-term reliability

Multi-busbar technology

Busbars are located on every pv module. These are rails that are permanently printed on each solar cell. They receive the direct current generated and feed it to the busbars. By using more of these busbars, Longi reduces shading, shortens the transport distances and reduces the resistance in the modules.

mic 2500tl-x string inverter

With the growatt mic 2500tl-x string inverter (mpn: mic 2500tl-x), we offer a single-phase inverter that combines high yields with user-friendliness. It is particularly suitable for small pv systems and delivers up to 2500w AC output power. Simply connect it to your Solarasystem via the MC4 connection and you're ready to go. This allows part of the power requirement to be covered cost-effectively.
the device can also be monitored and configured on the move using the Shine app or web application via an optional WLAN module.

Why a string inverter: The output of solar panels varies depending on temperature, irradiation and shading, which can lead to so-called mismatching losses. These losses occur as soon as the output of a panel in a row is lower, which leads to lower electricity production for the entire row. A string inverter can reduce these losses.
Maximum Power Point Tracking: Maximum Power Point Tracking technology is used to generate the best possible yield from a Solaranstallation. The mppt of the mic inverter sets the optimum ratio between voltage and current over the course of the day, depending on the solar radiation and the temperature of the solar modules. The wide mppt voltage range means that a large number of solar modules can be connected and this enables efficient energy yield, the advantage of which is most noticeable when the sky is partially overcast and the light intensity is constantly changing.
Flexible and easy installation: Thanks to its compact dimensions and low weight, the inverter is quick and easy to install and connect. Thanks to the integrated MC4 connections, the connection from the solar supply to the inverter is also completed in just a few moments. The numerous protective functions ensure safe and smooth operation of the Solarasystem.
