Huawei kit, sized from the record
Off-grid solar system for a villa, with Huawei 3 × LUNA2000-21-S1 storage
Worked out for a villa running air conditioner ×4 at 4,800 W, kitchen (microwave & kettle) at 2,000 W, washing machine at 800 W, water pump at 750 W, lights & Wi-Fi ×2 at 400 W, freezer at 200 W, TV ×2 at 200 W, fridge at 150 W with no utility supply. The Huawei unit it names is the storage — 3 × LUNA2000-21-S1 batteries (62.1 kWh in all). The inverter is stated as 12 kW with no model beside it, since no single-phase SUN2000-LB0 goes past 6 kW. With three phases at the meter, the SUN2000-12K-MAP0 is the Huawei hybrid of that size.
What is inside
Inverter×1
12 kW hybrid inverter — a rating, not a model: the single-phase SUN2000-LB0 family stops at 6 kW

Solar panels×22
22 panels of 550 W, near 57 m² of roof — a count: this catalogue holds no Huawei panel
How the load turns into these units
Start every motor on this list together and the draw touches 11.7 kW; across a full day the same list consumes close to 49.5 kWh. On one phase that means 12 kW of inverter. The SUN2000-LB0 line listed here, which begins with the SUN2000-3K-LB0, spans 3–6 kW — short of it — so this page prints the rating and leaves the model blank. A building fed by three phases has a Huawei answer: the SUN2000-12K-MAP0, 12,000 W and AED 5,309, whose record puts each PV input at 16 A and its working window at 160–1000 V.
Refilling the day takes 11.6 kWp, which is 22 panels over roughly 57 m², figured on 5.7 hours of full sun per day. No panel in this catalogue is a Huawei product, which is why the array appears as a size and a count.
Nothing stands behind this kit when the sun is down, so the store of energy is a whole day's use plus a margin for an overcast one: 49.5 kWh. 3 × LUNA2000-21-S1, 20.7 kWh apiece, bring 62.1 kWh. Its record lists the modules it stacks: LUNA2000-5-E1 (5kWh) / LUNA2000-7-E1 (6.9kWh). Chemistry is LiFePO4, and 10.5 kW is the most one unit moves in or out. Its bus sits at 350–560 V behind a single-phase SUN2000 and at 600–980 V behind a three-phase one. Bring help to the store: a unit is 216 kg. The enclosure is IP66 and its stated working range is -20 °C ~ +55 °C.

What buyers ask about this Huawei kit
Which SUN2000 does a kit like this one (villa) run on?
On no single-phase SUN2000: 12 kW is what this load asks of one phase, and the LB0 family tops out at 6 kW. The Huawei 12 kW Three-Phase Hybrid Solar Inverter SUN2000-12K-MAP0, AED 5,309, covers it where the supply is three-phase.
How many kWh does the kit store, and where does that number come from?
62.1 kWh, as 3 × Huawei 20.7 kWh Lithium Solar Battery LUNA2000-21-S1. One day of this load and an overcast-day margin make 49.5 kWh, and this is the least that covers it.
Does Huawei make the panels in this kit?
No — we list SUN2000 inverters, LUNA2000 batteries and their accessories, and no panel. The 22 panels (11.6 kWp, 57 m²) are a requirement to be met with modules bought elsewhere.
How much is the Huawei hardware in this kit?
3 × LUNA2000-21-S1 at AED 12,112 — AED 36,336 for the set. These are the figures printed on the units' own pages, for goods collected from our store in Dubai or Riyadh.
Which LUNA2000 comes next if the load grows?
LUNA2000-21-S1 belongs to a family listed at 5, 6.9, 10, 11.9, 13.8, 15, 16.9, 18.8 and 20.7 kWh. It is the top of that family, so more capacity means a second unit.
