Kit Contents
36× 590 W N-Type TOPCon bifacial dual-glass solar modules
Total array power 21.24 kWp. Vmp 44.35 V, Voc 52.82 V, Imp 13.30 A, Isc 14.02 A, size 2278 × 1134 × 30 mm.
1× FoxESS T17-G3 17 kW three-phase string inverter
Converts the module output to AC and feeds it into the grid. 2 MPPT, 140–1000 V, 28 A per MPPT (2 strings).
1× Three-phase AC panel 20 kW 32 A with CEI 0-21 interface protection (SPI), RCD and SPD, IP65
Protection and isolation of the AC grid connection.
1× DC field box 1000 V for 4 strings with Type 2 SPD
Surge protection of the PV strings on the DC side; DC isolation is built into the inverter.
PV String Design
4 strings of 9 modules, distributed 2 / 2 across the MPPTs. Operating voltage Vmp 399.2 V, Voc at 25 °C 475.4 V, worst-case Voc at −25 °C 542 V (conservative coefficient −0.28 %/°C) — within the inverter’s 1100 V limit and the 1000 V rating of the protection boxes. Maximum current per MPPT 26.6 A, within the input limit (2 MPPT, 140–1000 V, 28 A per MPPT (2 strings)). DC/AC ratio 1.25×.
Storage, Grid and Operation
Grid-tie string inverter without battery, CEI 0-21 compliant, with built-in DC isolator. Above 11.08 kW the Italian CEI 0-21 standard requires external interface protection: it is built into the kit’s AC panel.
A consistent, well-engineered system
The kit uses selected components and a PV configuration calculated and checked against the inverter’s electrical limits, ready for installation by qualified personnel. The product includes only the listed components. Mounting structures, cables, connectors, installation, permits, commissioning and any additional protection required by the design or lightning-risk assessment are not included. Shipping is a flat €120 in Italy and €350 within the European Union.
