Examples of installation architectures Installations > 100 kw - Ue y 800 V DC In the case of a PV architecture with an earthed polarity on the DC side and a central inverter having galvanic isolation and an IT earthing system on the AC side, it is necessary to: b protect each string of photovoltaic modules with a installed in the protection cabinet for the PV strings located near the PV modules b add a earth protection circuit breaker, with all poles in series, on the DC side of the PV inverter. PV inverter stoppage is actuated via an auxiliary contact combined with the earth protection circuit breaker. Polarity earthing and the protective device should not be implemented if the PV inverter already has an earthed polarity. If the Isc of the DC installation exceeds 1.5 ka, replace the earth protection circuit breaker with an NSX80 DC PV provided with a 16 A release.

32 Complementary technical information Examples of using switch-disconnector Architectures 10 kw-100 kw grid-connected PV system (small buildings) Three-phase multi-input inverter without array box Typically, 10 kw to 36 kw grid-connected inverters with U OC MAX probably higher than 600 V (i.e. 800 V or 1000 V) and I SCTC < 125 A, I AC < 63 A. In this range of power, inverters usually have between 2 and 4 maximum power point tracking (MPPT) inputs, so the number of strings in the same DC sub-network is equal to one or two. There is no need for string protection. A PV main switch for each MPPT input is necessary. When an inverter is indoors, additional remote-controlled switches at DC cable entry point are recommended for emergency services.

U OC MAX is generally higher than 600 V (up to 1000 V), I SCTC does not exceed 200 A, I AC does not exceed 100 A. This design has more than 2 strings. Reverse current protection is therefore necessary. A main PV switch is required.
