Kit Contents
48× 590 W N-Type TOPCon bifacial dual-glass solar modules
Total array power 28.32 kWp. Vmp 44.35 V, Voc 52.82 V, Imp 13.30 A, Isc 14.02 A, size 2278 × 1134 × 30 mm.
1× Huawei SUN2000-20K-MB0 20 kW three-phase hybrid inverter
Manages PV generation, battery charging and discharging and grid exchange. 2 MPPT, 200–1000 V (full power 480–800 V), 30 A per MPPT (2 strings).
1× Huawei DTSU666-H three-phase Smart Power Sensor with 3 split-core 100 A CTs
Measures grid import/export: required for self-consumption, battery management and export limitation.
1× Selectable storage: Huawei LUNA2000-S1
20.7 kWh: 1× Huawei LUNA2000-10KW-C1 power module, 3× Huawei LUNA2000-7-E1 6.9 kWh battery module or 41.4 kWh: 2× Huawei LUNA2000-10KW-C1 power module, 6× Huawei LUNA2000-7-E1 6.9 kWh battery module.
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 12 modules, distributed 2 / 2 across the MPPTs. Operating voltage Vmp 532.2 V, Voc at 25 °C 633.8 V, worst-case Voc at −25 °C 723 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, 200–1000 V (full power 480–800 V), 30 A per MPPT (2 strings)). DC/AC ratio 1.42×.
Storage, Grid and Operation
The Huawei SUN2000-20K-MB0 accepts up to 4 LUNA2000-S1 systems (2 on each of its two battery inputs); each system is one C1 power module plus 3 × 6.9 kWh modules. The included Smart Power Sensor is required for self-consumption. 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.
