What is the difference between a stand-alone solar controller and a solar controller built into an inverter

The solar controller is an important component in the solar power generation system. The solar controller is an automatic control device used in the solar power generation system to control multiple solar cell arrays to charge the battery and the battery to power the solar inverter load.

It stipulates and controls the charging and discharging conditions of the battery, and controls the power output of the solar cell components and the battery to the load according to the power demand of the load. It is the core control part of the entire photovoltaic power supply system.

Inverters on the market now have built-in controller functions, so what is the difference between an independent solar controller and a solar controller built into the inverter?

A standalone solar controller is a separate device that is usually separate from the inverter and requires a separate connection to the inverter.

The solar controller built into the inverter is part of the inverter, and the two are combined to form an overall device.

Independent solar controllers are mainly used to control the charging process of solar panels, including monitoring the voltage and current of solar panels, controlling the charging status of batteries and protecting batteries from overcharge and over-discharge.

The solar controller built into the inverter not only has the charging control function of the solar panel, but also converts solar power into AC power and outputs it to the load.

The combination of a solar controller and an inverter not only reduces the number of components of the solar power generation system, but also saves installation space.

Since the independent equipment components of the independent solar controller are separated from the inverter, from the perspective of later maintenance, the replacement of the equipment is also more convenient and saves costs.

Independent solar controllers can choose different specifications and functions according to actual needs, and can more flexibly meet users' different application needs. The solar controller built into the inverter usually has fixed specifications and functions and is not easy to replace or upgrade.

Standalone solar controllers are better suited for applications that require greater customization and flexibility, while solar controllers built into the inverter are better suited for applications that simplify installation and reduce the number of devices.

If you have a small solar power generation system, we recommend an inverter with a built-in controller. The structure of the solar power generation system is simpler, which can save space and cost. It is a more economical and practical choice and is more suitable for small solar power generation systems. Power system.

If you have a medium to large system that needs better management and has enough space and budget, an independent solar controller is a good choice. It is an independent device and is more convenient for subsequent maintenance and replacement.
