3 kWp photovoltaic kit connected to the grid with Huawei Battery ready panels and inverter
3 kWp grid-connected solar kit with Huawei SUN2000-3KTL-L1 hybrid inverter, Huawei DDSU666-H Smart Meter for zero-export control and high-quality solar panels (minimum 3,000 Wp). Battery Ready: compatible with Huawei LUNA2000 and LG Chem storage — no retrofit required. Net metering ready. Full monitoring via Huawei FusionSolar app (iOS/Android).
Kit includes: high-quality solar panels (min. 3,000 Wp) · Huawei SUN2000-3KTL-L1 inverter (3 kW, single-phase, IP65) · Huawei DDSU666-H Smart Meter.
The 3 kWp on-grid Huawei solar kit is a complete solution for building a residential single-phase solar system with net metering, designed for homeowners who want to reduce electricity bills and have the flexibility to add battery storage in the future. At the heart of this kit is the Huawei SUN2000-3KTL-L1 hybrid inverter — one of the most reliable single-phase inverters on the market, with a maximum efficiency of 98.6% and native Battery Ready compatibility with Huawei LUNA2000 lithium batteries.
Why choose a 3 kWp grid-connected solar kit?
A 3 kWp on-grid system is the most popular size for residential single-phase homes with average electricity consumption. It produces solar energy during daylight hours to power domestic loads, and any surplus is fed back to the grid and compensated through net metering schemes. With optional battery storage, excess energy can be stored for evening use, maximising self-consumption and reducing grid dependence throughout the day.

Battery Ready: what it means and why it matters
The Huawei SUN2000-3KTL-L1 is a hybrid inverter with a native interface for Plug & Play connection with Huawei LUNA2000 lithium batteries. No retrofit or additional device is required: simply connect the battery module of your choice to convert the system into a full hybrid with storage. The Battery Ready feature protects your investment over time, allowing you to add storage whenever you want — or when battery prices drop further.

Frequently asked questions
Is this 3 kWp solar kit suitable for my home?
A 3 kWp system is ideal for single-phase homes with average electricity consumption (2,500–4,000 kWh/year), such as apartments or small houses with a fridge, washing machine, air conditioning and programmable loads. Maximum benefit is achieved by consuming energy during solar production hours — scheduling appliances at midday can significantly increase self-consumption. For higher consumption or if you plan to charge an electric vehicle, the 6 kWp kit may be a better fit.
Can I add batteries later without replacing the inverter?
Yes. The Huawei SUN2000-3KTL-L1 is Battery Ready: it has a native interface for Plug & Play connection with Huawei LUNA2000 batteries. No retrofit, adapter or modification to the existing system is needed. Simply add the battery module (from 5 to 30 kWh expandable) and the system automatically becomes a hybrid with storage, managing charge and discharge cycles intelligently.
How much energy will a 3 kWp system produce per year?
Annual production depends on location, panel orientation and tilt. As a general estimate for Italy: Northern Italy 2,700–3,300 kWh/year, Central Italy 3,300–3,900 kWh/year, Southern Italy and Islands 3,900–4,500 kWh/year. For other countries, the PVGIS tool (free European Commission simulator) provides precise estimates based on GPS coordinates, orientation and shading.
Does the kit include zero-export control?
Yes. The Huawei DDSU666-H Smart Meter included in this kit measures energy flows in real time and enables zero-export mode, preventing the system from injecting surplus power into the grid when required. This feature is increasingly important where grid operators impose zero-feed-in limits for small residential systems.
