Huawei kit, sized from the record

Solar system for an apartment with overnight backup power, on the Huawei SUN2000-5K-LB0

Worked out for an apartment running air conditioner at 1,200 W, washing machine at 800 W, lights & Wi-Fi at 200 W, fridge at 150 W, TV at 100 W through an 8-hour night without the grid. At its centre sits Huawei's SUN2000-5K-LB0, a hybrid for one phase rated 5 kW, with 5.1 kWh of storage behind it.

The 4-hour and the 8-hour versions of this kit carry an identical 5.1 kWh: the shorter window takes 2.3 kWh out of it, the longer one 4.6 kWh. Both are fed by the same 3 kWp of panels. Solar system for an apartment with evening backup power

How the load turns into these units

Start every motor on this list together and the draw touches 4.9 kW; across a full day the same list consumes close to 13.8 kWh. Its record gives the SUN2000-5K-LB0 5,000 W of single-phase AC output at up to 97.8% efficiency — enough headroom for that starting moment.

Whatever panels are chosen have to be strung for the SUN2000-5K-LB0: 2 MPPT inputs, 16 A on each, tracking from 40–560 V and never above 600 V. Refilling the day takes 3 kWp, which is 6 panels over roughly 16 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.

The storage answers one question — what this list consumes during the 8 hours the grid is away — and the answer is 4.6 kWh. The kit carries 5.1 kWh for it in one unit, given as a capacity with no model attached.
