800 W microinverter without electricity meter

Product detailed description

The SPD series microinverter is a modern solution for efficient use of energy from photovoltaic panels. It converts direct current (DC) from the panels into alternating current (AC), which is compatible with standard electrical networks.

Thanks to the anti-islanding function, the device immediately stops generating energy and isolates the voltage on the output cable in case of sudden disconnection from the socket or a power outage in the grid. This ensures safe use in homes.

The MPPT (Maximum Power Point Tracking) technology ensures maximum performance from each panel. You can monitor production via the Smart Life (Tuya) mobile app, where you can view current performance, device status, and perform firmware updates.

The IP67 rating allows for outdoor installation and resistance to harsh weather conditions. The design for low-voltage direct current increases safety compared to traditional high-voltage string systems.

Important note: Installation of photovoltaic panels and any work on the electrical installation must be carried out only by a qualified electrician. The information provided here is for general technical purposes only and does not replace professional inspection and assessment of the electrical installation.

To connect to the distribution network, it is necessary to notify the distribution network operator (ČEZ, PRE, EG.D) and comply with their requirements. Improper installation or failure to follow applicable regulations may pose a risk of injury, damage to equipment, or penalties. The seller is not liable for damages or malfunctions caused by incorrect installation, unprofessional interference with the electrical installation, or non-compliance with current legal regulations.
