Huawei SUN2000-3.68K-LB0 single-phase hybrid inverter 3.68 kW
Huawei SUN2000-3.68K-LB0 single-phase hybrid inverter, 3.68 kW with 2 MPPT and 16A MPPT current. Battery ready for Huawei LUNA2000 storage, AFCI arc-fault protection, IP66 rating and natural cooling. Compliant with EN 50549 / G98-G99. 10-year warranty, extendable to 20. Ideal for residential self-consumption.
The Huawei SUN2000-3.68K-LB0 is a single-phase hybrid inverter rated 3.68 kW from the new LB0 series, designed for residential PV systems focused on maximum self-consumption. It combines a grid-tie inverter and a high-voltage battery charger in one unit, is battery ready (Huawei LUNA2000 Plug&Play) and complies with grid standards such as EN 50549 and G98/G99.
Why choose a Huawei hybrid inverter?
A hybrid inverter manages PV generation, battery charging and household loads at the same time, increasing the share of self-produced energy you actually use. The SUN2000-3.68K-LB0 uses 2 MPP trackers with 16A current to harvest the most from arrays with different orientations, and integrates AFCI protection that detects DC arc faults up to 200 m away and trips within 0.5 seconds, reducing fire risk.

What it means in everyday life
Paired with a 4–5 kWp array, the SUN2000-3.68K-LB0 in a Southern-European home produces about 4,500–5,500 kWh per year, enough to cover most of a family's consumption. Adding a LUNA2000 5–10 kWh battery stores daytime energy for the evening, pushing self-consumption to 70–80%: fridge, lights, TV and small appliances run on solar power instead of grid power.

Frequently asked questions
Does the SUN2000-3.68K-LB0 work without a battery?
Yes. It is a battery-ready hybrid inverter: it works immediately as a standard grid-tie inverter, and the Huawei LUNA2000 battery can be added later in Plug&Play mode without replacing the inverter.
With this inverter and a 10 kWh battery, how much of my home consumption can I cover?
For an average household using 3,000–3,500 kWh/year, a 4–5 kWp system with the SUN2000-3.68K-LB0 and a 10 kWh LUNA2000 battery can cover about 70–80% of yearly needs, using stored daytime energy in the evening.
Which battery is compatible with the SUN2000-3.68K-LB0?
It is compatible with Huawei LUNA2000 storage (5, 7, 10 kWh modules and above). Connection is Plug&Play thanks to the inverter's integrated battery interface.
Is it suitable for a single-phase residential system?
Yes, it is a 3.68 kW single-phase inverter designed for homes with single-phase supply and PV systems around 4–5 kWp. For higher power or three-phase supply, other SUN2000 models are available.
Is it compliant with grid-connection standards?
Yes, it meets EN 50549 and G98/G99, as well as national codes such as CEI 0-21 (Italy), VDE-AR-N 4105 (Germany) and RD 1699 (Spain) for low-voltage grid connection.
