The Growatt SPH 6000TL BL-UP photovoltaic inverter, a 6 kW single-phase hybrid model, represents an advanced solution for small-sized residential or commercial systems. This inverter model is designed to ensure high performance, with particular attention to ease of use and efficiency. Being a device used for four years, it is in good aesthetic condition, almost like new, although it requires the replacement or repair of the board to be fully operational.

Appearance and Components

The inverter stands out for its compact and modern design, easy to integrate into different types of installations thanks to its small size. The device is equipped with an LCD display to monitor operations and data in real time. Furthermore, it supports two MPPT (Maximum Power Point Tracking) inputs, which allows you to optimize energy production even in systems with solar panels arranged in multiple directions.

Measurements and Technical Characteristics

• Rated power: 6 kW
• Maximum efficiency: 97.7%
• Transformerless technology to improve conversion efficiency
• DC rated voltage: 600V
• Rated current: 25A
• Weight: about 20kg
• Built-in protections for overvoltage, overtemperature and network monitoring
• Automatic standby function with restart when the voltage from the solar panels is sufficient.

Procedure for Use

The operation of the inverter is automated: it starts converting energy when the solar panels generate sufficient voltage and turns off automatically when the sun goes down. The inverter connects directly to the electricity grid for energy input, and thanks to MPPTs, it can maximize energy production in conditions of irregularities in the distribution of solar panels.

Maintenance and Safety

Being a used device, it is essential to carry out good periodic maintenance, which includes cleaning the cooling fans and checking the correct functioning of the protection systems. Being compliant with CEI 0-21 regulations, this inverter complies with Italian regulations for connection to the electricity grid, making it safe to use in residential and commercial contexts. In case of lack of CE certification, it is necessary to check the local provisions for bringing the equipment into compliance.

Sectors of Use

This model is suitable for small domestic photovoltaic systems, but can also be used in small-scale industrial contexts, where intelligent energy management and the possibility of adding batteries are an advantage.

Advantages of Buying Used

Opting for a used inverter like the Growatt SPH 6000TL BL-UP can be a convenient choice from an economic point of view, especially if well maintained. Repairing the board represents a minimal investment compared to purchasing a new model, while still guaranteeing excellent performance and a long operating life.
