Why do PV plants use 800 VAC instead of DC?
For this reason, it is already common to find a new model the design of PV plants with 800 Vac, instead of DC. These installations have string inverters closer to the photovoltaic panels that are able to work at this voltage and offer high performance.
How to protect the output of string inverters in 800 V AC?
Facilitating the maintenance. Fuses with gG or gS curve are the only ones suitable for the protection of the output of string inverters in 800 V AC. Other curves, as for example the aR, present too high-power dissipation and too low breaking capacity.
Is 800 VAC a good choice for a photovoltaic plant?
The photovoltaic energy sector is demanding increasingly efficient and innovative solutions that reduce the consumption of resources and associated costs and are more environmentally sustainable. For this reason, it is already common to find a new model the design of PV plants with 800 Vac, instead of DC.
