Inverters

Reliable inverter solutions for solar panels

The efficiency of a solar power system depends not only on the quality of the panels – the inverter is the central unit that has a decisive influence on how much of the absorbed solar energy can actually be used. There is a growing demand in the industry for reliable solutions with long-term stable performance, such as modern Huawei inverters, which precisely and intelligently control energy flow in both residential and industrial environments.

State-of-the-art solar inverters are no longer just converters – they have become complex energy optimization centers. The possibility of feeding energy back into the grid and integrated battery management open up new dimensions in system design. Solutions such as Huawei batteries and other advanced batteries enable energy storage and intelligent management.

Imagine that your solar systems can be monitored in real time, quickly diagnosed, and maintained remotely – all of which significantly increases return on investment and minimizes operational risks. Reliable inverters not only improve efficiency, but also increase customer satisfaction.

Why is an inverter "essential" for solar power systems?

Without an inverter, a solar power system cannot function efficiently – the direct current (DC) generated by the panels must be converted into alternating current (AC) so that it can be used by domestic or industrial appliances and fed back into the grid. In addition, inverters enable the use of MPPT (Maximum Power Point Tracking), which improves the efficiency of AC/DC conversion, especially in changing light conditions or partial shading. Furthermore, modern inverters have safety features: they automatically shut down in the event of grid faults ("anti-islanding"), thus protecting maintenance personnel and the integrity of the grid. Overall, the inverter is the brain of the system, optimizing energy production, regulating the grid connection, and ensuring system reliability.

What is the difference between a hybrid and a conventional (string) solar inverter?

A traditional string inverter simply converts the DC power generated by a series of solar panels (strings) into AC power and then feeds it into the grid or to the load. Its advantages are its lower price and simpler installation, but its disadvantage is that shading or a fault in one panel can reduce the performance of the entire string.

A hybrid inverter, on the other hand, combines the functions of a traditional inverter and a battery charger, enabling energy storage and recovery. In the event of a power failure, it also acts as a backup power source and optimizes energy consumption – although it is more complex and expensive.

How do I choose the type of inverter for the solar panels I want to install?

When choosing an inverter, it is worth considering the following:

1. System size and design – for smaller systems, a string inverter is often sufficient, while for larger systems or in shaded environments, a micro or string inverter with MPPT multi-point conversion may be advantageous.
   
   
2. Power requirements and expansion options – if you are planning for expandability or later battery operation, a hybrid inverter may be preferable as it already includes storage management.
   
   
3. Budget and maintenance – string inverters are generally cheaper and easier to set up, while hybrid devices require a higher initial investment and more complex installation.
   
   
4. Energy independence, backup requirements – if protection against power outages is important, a hybrid inverter is the ideal choice; otherwise, disconnecting from the grid remains a viable solution in the event of a power outage.
   
   
5. Monitoring and smart features – some inverters offer built-in remote monitoring and system diagnostics to help optimize your system.

What permits are required to install an inverter?

There are several permits and regulatory requirements that must be met for the installation of an inverter:

• Electrician's license: the power supply must be connected by a qualified, licensed electrician.
  
  
• Mains connection permit: if the system is connected to the mains, the local electricity supplier's regulations (e.g. grid compliance, connection contract) must be observed.
  
  
• Building and local authority permits: a building permit may also be required for roof modifications or fixed installations.
  
  
• Safety and compliance certificates: inverters must have CE and EN standards and network certificates, such as anti-islanding protection.
  
  
• Quality standards: In Hungary, compliance with the MSZ HD 60364 standard and relevant electrical safety regulations is mandatory.
  

The exact licensing process may vary from project to project, so it is always advisable to consult with local authorities and your electricity supplier about the necessary steps.

What warranties do manufacturers offer for different inverters?

Manufacturers offer different warranty terms for inverters, which are often linked to the type and connection to the online system.

Huawei hybrid inverters come with a standard 5 or 10-year warranty, which can be extended to up to 15 years if the device is connected to the FusionSolar system.

For SolaX models (e.g. X1, X3, G4), the 5-year basic warranty is automatically extended to 10 years if the inverter is connected to the SolaX Cloud.

Deye SUN series inverters come with a 10-year warranty covering material defects and main components – however, the warranty is only valid for installations in Europe and requires appropriate documentation for validation.
