How does grid feeding work?

Grid feeding is a process where the generated electricity is fed directly from the solar module and the compatible inverter into the public power grid. The inverter is ideally mounted close to the solar modules and connected using solar connectors. Regardless of the system size, the solar installation must be registered with the Market Master Data Register in accordance with legal requirements.

Longi Hi-Mo-6 430W Solar Module

The Longi LR5-54HTH-430M is a 430W solar module with monocrystalline cells and part of the improved Hi-MO 6 product series. The HPBC cell technology uses full-back soldering technology, increasing resistance to microcracks. Compared to the previous series, Hi-MO 6 features improvements in performance, reliability, aesthetics, and optimization. The design simplifies complexity and redefines the visual concept of photovoltaic modules.

Features

• High-efficiency HPBC cell technology

MIC 2000TL-X String Inverter

The Growatt MIC 2000TL-X string inverter (MPN: MIC 2000TL-X) is a single-phase inverter that combines high yields with user-friendliness. It's ideal for small PV systems and provides up to 2000W AC output. Simply connect it via the MC4 connector and you're good to go. This allows a portion of your electricity demand to be covered cost-effectively.
An optional Wi-Fi module allows monitoring and configuration via the Shine app or web application.

Growatt MIC Inverter Overview

• Single-phase operation
• Maximum Power Point Tracking (MPPT)
• Connect directly to PV modules
• Touch button and OLED display
• Compact design and easy installation
• Optional: Monitoring via Shine platform (requires additional accessories)

Why a String Inverter?

Solar module performance varies due to temperature, sunlight, and shading, which can cause mismatch losses. If one panel in a string underperforms, it reduces output for the whole string. A string inverter helps minimize these losses.
MPPT: Maximum Power Point Tracking ensures optimal energy yield by adjusting voltage and current to match sunlight and module temperature. Its wide MPPT voltage range allows flexible connection and high efficiency, especially under fluctuating lighting conditions.
Easy installation: Thanks to compact dimensions and lightweight design, the inverter is quick to install. MC4 connectors simplify connection, and built-in protections ensure smooth and safe operation.
