You can also find lots of useful information in the following frequently asked questions and answers:

Why is the communication module (e.g. SolaX Pocket WiFi+LAN) important?

The communication module enables remote monitoring of the inverter and the system with real-time data collection and automatic fault reporting. The WiFi+LAN connection ensures a reliable data connection, can be used outdoors with IP65 protection, and generally does not require a separate power supply.

This makes it indispensable for efficient operation and maintenance.

What communication protocols do these accessories support?

Inverter accessories generally support multiple industrial standards, allowing them to be flexibly integrated into different systems:

• Modbus TCP/RTU – widely used, client-server architecture, reliable data transfer
  
  
• IEEE2030.5, OpenADR – important for energy planning, smart grids, and power market applications
  
  
• RS‑232/RS‑485 – classic serial interfaces, particularly common in older control systems

What is a performance optimizer and when is it particularly recommended?

Power optimizers are connected to each individual solar panel to maximize their individual output. They are particularly recommended if:

• There is partial shading, different tilt angles or panels with different orientations – each panel operates at its maximum capacity
  
  
• In hybrid systems, optimizers can achieve efficiencies of up to 98–99%, providing module-level control.
  
  
• They are particularly important for SolarEdge systems, where they are a mandatory component.

What is the role of an energy management assistant?

The energy management assistant (e.g., Huawei EMMA-A02) is responsible for the intelligent control of the system. Its tasks include

• Controls external relays (e.g., switching consumers) based on the current status of the system
  
  
• Optimizes energy consumption, e.g., battery charging/discharging, grid feed-in control.
  
  
• Helps to increase cost and energy efficiency, reacts proactively to production and consumption conditions.

How can inverter accessories be integrated into an existing system?

Integration is usually simple and step-by-step:

1. Physical connection – the module (e.g. dongle) is inserted into the appropriate port on the inverter
   
   
2. Communication setup – the protocols (e.g. Modbus, CAN, RS‑485) are configured on the inverter interface
   
   
3. Network connection – the module connects to the router via WiFi or LAN, ensuring sufficient network signal strength.
   
   
4. Connection to a monitoring platform – for example, cloud-based services or local SCADA systems.
   
   
5. Testing and commissioning – the protocol function, data transmission and regular data collection must be checked.

Is a separate power supply required for the operation of the accessories?

Most communication modules (e.g., SolaX Pocket dongle) use the inverter's internal power supply and therefore do not require a separate external power supply – they are "plug & play" devices. Other devices, such as the Huawei energy management assistant or measuring modules, generally use the 12–24 V DC supplied by the inverter and do not require a separate power source.

Opinions and recommendations from SOLARKIT experts

SOLARKIT experts clearly advise that the use of power optimizers in inverter systems is "not just an option, but a conscious decision" in designing an efficient and reliable system.

Optimizers ensure that each panel operates at its maximum power, even in the event of partial shading or panel differences.

They also emphasize that optimizers are particularly recommended for installation situations such as fragmented roof surfaces, different tilt angles, or future expansion plans, as they provide greater flexibility in system design and operation.

The experts also emphasize that although optimizers do not directly increase the service life of components such as inverters, their use can reduce the load on the equipment and thus indirectly contribute to the long-term reliability of the entire system.

Overall, the SOLARKIT team believes that optimizers are a long-lasting, low-maintenance, cost-effective investment. They increase system performance, make it scalable, and improve installation flexibility—all of which make them an economical choice for any modern solar power system.
