A Pakistani house needs hybrid, not an export farm.
Load-shedding at night, AC in the afternoon, fridge that cannot die. After SRO 251 you size PV to daytime load and buy LFP for the shed — you do not oversize to dump units at Rs 11.
What a house actually runs
The 2026 family stack.
| House | Typical load | PV (645 W plates) | Inverter | Battery | Street band |
|---|---|---|---|---|---|
| Small / 3-marla / shop-house | Fans, lights, fridge, TV, router | 6–7 plates · ~4 kW | 3.6–6 kW hybrid | 1 × 5 kWh LFP | Rs 0.95–1.5 million |
| Family default / 5–10 marla | Above + one 1.5-ton AC by day | 10 plates · 6.45 kW | 6 kW IP65 hybrid | 1–2 × 5 kWh LFP | Rs 1.7–2.5 million |
| Large / 1 kanal, two ACs | Two 1.5-ton, pump, freezer | 16 plates · 10.3 kW | 10 kW hybrid | 2–3 × 5 kWh LFP | Rs 2.9–4.4 million |
Bands include 14 SWG iron, XLPO, SPD, earthing, labour. Green meter is the DISCO demand notice. Confirm live SKUs.
Backup split
The whole DB does not go on the hybrid.
Must run in shed
LED lights, ceiling fans, fridge, router, maybe one inverter AC if the LFP bank was sized for it. That is the house staying live at 2 a.m.
Dies with WAPDA — on purpose
Geyser, extra ACs, iron, washing machine, workshop welder. Putting these on backup is how a 6 kW hybrid trips and the fridge dies with them.
Fridge is non-negotiable
A house hybrid without a battery is an on-grid system with extra cost. If the feeder sheds, the fridge is why you bought hybrid.
Night AC is a second cheque
One 1.5-ton for six night hours is ~7 kWh usable — two 5 kWh LFP packs. See single AC before you promise “AC chalay ga”.
Net-billing is optional
Many houses self-consume the afternoon AC and export almost nothing. File the DISCO paper if you have surplus. Do not size the roof for it.
Spec
What we put on a house this month.
Plates
Documented N-type 610–650 W (Hi-MO X10 / Tiger Neo 3.0). 575–590 W TOPCon if the roof is short. No PERC leftover.
Box + bank
IP65 hybrid (Inverex Nitrox / Knox / SolarMax). Default Dyness or Knox 5.12 kWh LFP. Tubular only if the budget is the constraint and nights are fans+lights.
BOS
14 SWG HDG L2, XLPO 6 mm², chemical earth, SPD, labelled isolators. 16 SWG + PVC is a two-summer house.
