Pronutec presents its new 800 VAC Combiner Panels range. Working voltages from 400 V to 800 V in AC grids, both in indoor and outdoor installations. Wide range of; currents, number of inputs, different switching devices, surge protection, and auxiliary services.

These panels are the ones that are differently connected to the transformer in the Transformer Station. The panel collects the cables from the inverter, through the bottom,  by means of fuse switch NH 00/1/3. These fuse switches have been tested and are capable of working at voltages up to 800 V AC.

Main features of our range of  800V AC combiner panels 

Depending on the needs of our customers and the requirements of each solar plant, we design and develop a wide range of low voltage panels for photovoltaic applications:

• Voltage values: from 400 V  to 800 V.
• Current values: up to 4000 A.
• From 4 to 16 feeders of size NH1/3.
• With optional load break switch or automatic circuit breaker.
• For indoor or outdoor installation.
• Choice of different types of enclosures.
• Multiple accessories available.

PV energy shouldn’t be considered any more an alternative source of energy. As it is becoming more cost-competitive, it is now an increasing reality.

One of the main reason for this, is the reduction of installations and maintenance cost. New trend consist in designing photovoltaic distribution network in 800 V AC instead of DC voltages with smaller string inverters close to the photovoltaic panels.

At the same time, the transmission of energy at higher voltages make possible to reduce power losses and the cost of the installation.

By using upper section cables, up to 300 mm2 for NH 1 and NH 3, the voltage drop is reduced. In this way, the tendency in last inverters generation is to transmit at 800 V AC.

Our range includes:

• LV Vertical Fuse Switches of Pronutec for 800 V AC
• SIBA NH fuses
• High-performance switch disconnectors of Telergon for 800 V AC
• Automatic Switch disconnectors
