Inverters are one of the most crucial components for safe, efficient, and sustainable electricity generation in solar energy systems. These devices convert direct current (DC) electricity generated from solar panels into alternating current (AC) electricity used in homes and businesses.

On-grid inverters not only perform this conversion but also manage the generated energy in integration with the grid. Inverter installation in grid-connected systems is critical for energy efficiency, safety, and longevity.

In this article, we will thoroughly examine the operating principle of on-grid inverter systems, the installation steps, Solinved's engineering distinction, and why proper installation is so crucial.

What is an On-Grid Inverter?

On-grid inverters are a type of inverter that enables grid-connected operation in solar energy systems.
These inverters convert electricity from solar panels into AC and transfer it to the grid.

The primary purpose of this system is to use the energy generated from the sun for personal consumption and sell any excess energy back to the grid.

Solinved on-grid inverters stand out with their high conversion efficiency, advanced security features, and remote monitoring technology.

On-Grid Inverter Operating Principle

The energy flow in on-grid systems occurs as follows:

Solar Panels: Convert sunlight into electrical energy (DC).

Inverter: Converts DC energy to AC.

Distribution Panel: The converted energy is first used for internal building needs.

Grid Integration: Unused surplus energy is transferred to the public grid.

Energy Monitoring: The Solinved remote monitoring system monitors production and consumption data in real time.

This structure allows users to both generate their own energy and profit economically from surplus energy.

Before Beginning On-Grid Inverter Installation

There are technical and administrative steps to consider before installing an on-grid system. Solinved plans all these processes with its professional engineering team prior to installation.

1. Site Survey and Solar Radiation Analysis

Before installation, the panel layout, tilt angle, and orientation are analyzed. The region's annual sunshine duration is calculated.

2. Determining System Capacity

Panel power and inverter capacity are determined based on the user's energy needs. At this stage, the nominal inverter power is selected to be proportional to the panel output power.

3. Legal Permits and Grid Approval

For grid-connected systems, approval must be obtained from distribution companies. The Solinved technical team manages this process on behalf of the user.

4. Equipment Selection

Solar panels

Inverter

DC cables and connectors

AC connectors

Protection panels and fuse systems

Compliance with all this equipment to Solinved standards is essential for system safety and longevity.

On-Grid Inverter Installation Steps

1. DC Connections

Solar panels are connected in series or parallel and connected to the inverter input with DC cables.
Polarity must be observed when making this connection. Incorrect connection may damage the inverter.

The MC4 connectors on Solinved inverters ensure a fast and secure connection.

2. AC Output Connection

The inverter's AC output is connected to the building distribution panel.
This connection transfers the generated energy to the building's systems.
It is important to connect the phase and neutral lines correctly.

3. Grounding System

Grounding both the inverter and the solar panels is mandatory for electrical safety.
The grounding line protects the system from situations such as stray current or lightning.

4. Installation of Protection and Safety Equipment

Protection relays and fuses are added to protect against overvoltage, short circuit, or reverse current.
AC and DC protection panels are standard in Solinved systems.

5. Adjusting the Inverter Settings

After installation, the inverter is configured according to the system parameters. These settings include:

Grid frequency (50 Hz)

Nominal voltage (230V/400V)

Power limiting settings

MPPT (Maximum Power Point Tracking) optimization

Solinved smart inverters automatically optimize these settings, reducing installation time.

6. Activating the Remote Monitoring System

Solinved inverters can be connected to a remote monitoring system via Wi-Fi or Ethernet.
Users can monitor real-time production data, energy consumption, and system status via the mobile app.

7. Testing and Commissioning

After all connections are complete, the system is tested.
DC and AC voltage measurements are performed, and the inverter is commissioned.
After production begins, production values ​​are checked on the inverter screen or software panel.

Points to Consider When Installing an On-Grid Inverter

Install the inverter in a location away from direct sunlight or moisture.

Keep the cable distance between the panels and the inverter as short as possible.

The cross-section of DC cables should be selected according to the current rating.

Adequate air circulation should be provided around the inverter to prevent overheating.

Connection to the grid should only be made under the supervision of a qualified electrical engineer.

The Solinved technical team supports the user at every stage of the process and ensures the safest system commissioning.

FAQs (Frequently Asked Questions)

1. What is an on-grid inverter and how does it work?
It converts DC electricity generated by solar energy into AC and operates in integration with the public grid.

2. Do on-grid systems require batteries?
No. Since these systems are grid-integrated, batteries are not required. However, battery integration is possible with hybrid inverters.

3. How long is the installation time?
For residential systems, it typically takes 1–2 days. For larger systems, this time can extend to several days.

4. What power ranges are Solinved inverters available in?
Solinved offers a wide range of products, from 3 kW residential models to 100 kW industrial inverters.
