A 10 marla house is the most common size we quote for, and also the size where buyers get the most contradictory advice. One dealer says 3kW is plenty. The next insists on 8kW. Both are describing a 10 marla house, and both can be right, because the plot size tells you almost nothing about the electrical load inside it.
What actually decides the answer is how many air conditioners run at the same time, whether the geyser is electric or gas, and whether you want the whole house backed up or only the essentials. Once those three things are settled, the capacity becomes obvious and the shortlist gets short.
This guide gives you the load numbers for a typical 10 marla home, the right capacity for each realistic scenario, indicative price ranges and the specifications worth insisting on before you pay. For a quotation matched to your own load, WhatsApp 03192070022.
The Short Answer
For most 10 marla homes in Pakistan, a 5kW hybrid inverter is the correct choice. It comfortably handles one 1.5 ton air conditioner running through the evening alongside fans, lighting, refrigerator, television and a water pump, with enough margin left that the unit is not running at its ceiling every summer night.
Move up to 6kW if two air conditioners could run at the same time, which is the situation in a majority of 10 marla homes with three or more bedrooms occupied.
Drop to 3.6kW only if the house runs no air conditioning, or uses a single AC very sparingly, and you accept that adding cooling load later means replacing the inverter rather than upgrading it.
The rest of this guide shows the working behind those numbers so you can place your own house accurately.
What a 10 Marla House Actually Draws
A 10 marla plot is roughly 2,250 square feet, and the houses built on them vary from three bedrooms to five or six across two floors. Here is a realistic load profile for a typical family home, using running wattage rather than nameplate figures.
| Load | Quantity | Running Watts |
|---|---|---|
| 1.5 ton inverter AC | 1 | 900–1,600 |
| Ceiling fans | 4–6 | 240–480 |
| LED lighting throughout | — | 120–250 |
| Refrigerator | 1 | 100–200 |
| Television and router | — | 80–150 |
| Water pump (0.5HP, intermittent) | 1 | 370–450 |
| Washing machine (intermittent) | 1 | 300–1,200 |
| Iron or microwave (occasional) | 1 | 1,000–1,600 |
The important column is not the total of everything you own. It is the total of what runs simultaneously during an outage, which is a much smaller number for most households.
Essential load only (fans, lights, fridge, router, television) lands around 550W to 1,000W. Almost any inverter handles this.
One AC plus essentials lands around 1,800W to 2,600W. This is where a 5kW unit sits comfortably with headroom.
Two ACs plus essentials lands around 2,900W to 4,000W. This is where 5kW starts feeling tight and 6kW becomes the sensible purchase.
If you want to build this number precisely for your own house rather than using a bracket, our room-by-room load calculation guide walks through it appliance by appliance.
Surge Matters as Much as Running Load
A 10 marla house usually contains at least two motor-driven appliances, an air conditioner compressor and a water pump, and sometimes a washing machine as well. Each of these demands a brief burst of power far above its running figure at the instant it starts.
This is why two inverters both labelled 5kW can behave completely differently in the same house. One trips when the AC compressor kicks in while the pump is already running. The other does not. The difference is the surge rating, which is quoted in VA and often printed in smaller type than the headline capacity.
For a 10 marla home with one AC, look for a surge rating of at least 6,000VA to 7,000VA. With two ACs that could start close together, 8,000VA and above gives you real margin. Ask the dealer for the surge figure specifically, and treat an inability to answer as information about the dealer.
Three Scenarios, Three Recommendations
Scenario 1: Essentials only, no AC backup
You want fans, lights, refrigerator, router and television through load shedding, and you are happy for the ACs to stay on grid power only.
Recommended: 3kW to 3.6kW hybrid inverter. Indicative price range roughly Rs. 90,000 to Rs. 175,000 depending on brand, protection rating and MPPT configuration.
This is the cheapest route to meaningful backup, and it suits households whose main complaint is sitting in the dark rather than sitting in the heat. The honest limitation is that it closes the door on AC backup later.
Scenario 2: One AC plus the whole house
You want one bedroom cooled during an outage, along with everything in the essential list.
Recommended: 5kW hybrid inverter. Indicative price range roughly Rs. 103,000 to Rs. 235,000, with the wide spread explained by protection rating, surge capability and brand.
This is the single most common correct answer for a 10 marla house, and it is also where the Pakistani market is most competitive, so value is strong at this capacity.
Scenario 3: Two ACs plus the whole house
Two bedrooms cooled simultaneously on a summer night, plus essentials, plus occasional pump and washing machine use.
Recommended: 6kW hybrid inverter. Indicative price range roughly Rs. 116,000 to Rs. 285,000.
The step up from 5kW to 6kW is modest in rupees and significant in daily experience if your household genuinely runs two ACs.

Hybrid, On-Grid or Plain UPS?
A 10 marla buyer is usually choosing between three different products, and the names get used loosely.
Plain UPS inverter. Battery backup only, no solar input. Cheapest option, runs your essentials through outages, does nothing for your electricity bill. Sensible if your bill is modest and backup is the only goal.
On-grid (grid-tied). Solar panels feed the house and export surplus through a net meter, with no battery. Best payback on a high bill, but the house goes dark during an outage because safety rules require the inverter to disconnect.
Hybrid. Solar, battery and grid managed together. Costs somewhat more than on-grid at the same capacity, and it is what most 10 marla households actually want, because load shedding has not disappeared and nobody wants a solar system that switches off during an outage.
For a 10 marla home with a meaningful electricity bill and regular outages, hybrid is almost always the right structure.
Specifications Worth Insisting On
At this capacity, the features below separate a unit that serves a 10 marla house well from one that merely fits the label.
Dual MPPT with 18A or higher per tracker. Lets you split panels across two roof faces, or separate a shaded section from a clear one, and avoids bottlenecking modern 580W to 620W panels.
Adequate surge rating. Covered above, and the single most overlooked figure.
Dual output or load prioritisation. Lets the inverter drop the ACs during a long night outage while keeping fans, lights, fridge and router alive on battery. Customers notice this feature more than any other in daily use.
Lithium BMS communication. Even if you start with lead-acid, buying a unit that can talk properly to a lithium pack keeps the upgrade path open. Retrofitting support later means replacing the inverter.
A protection rating that matches the mounting position. An indoor-rated unit belongs in a ventilated utility room, not on an exterior wall. If your only indoor option is a hot sealed store room, a sealed outdoor-rated unit on a shaded wall is the better installation.
PV oversizing headroom. Most hybrids in this class accept panel arrays well above their rated output, which is what keeps generation usable through foggy December and January rather than collapsing for three months.
Our best inverter for home in Pakistan guide names specific models that meet these criteria at each capacity.
Panels and Batteries to Match
The inverter is typically only 15% to 25% of a complete system, so budget for the rest.
Panels. A 5kW to 6kW hybrid commonly pairs with ten to fourteen modules of 550W to 620W, and most units accept more than their rated capacity in DC input. Using that headroom is how you keep winter output usable.
Battery bank. This is where backup duration is decided, and where most households under-budget. An inverter sized correctly but paired with too few batteries still leaves you dark within an hour. Lithium’s deeper usable discharge changes the arithmetic considerably against lead-acid at the same physical bank size. Our how many batteries for a 6kW inverter guide works through the maths for both chemistries, and because battery rates move almost weekly, WhatsApp us now for the latest price of the battery at 03192070022.
Balance of system. Mounting structure, correct-gauge DC and AC cable, breakers, surge protection and proper earthing. Do not economise here. Grid spikes and bad earthing destroy more inverters in Pakistan than manufacturing defects do, and no warranty covers a surge kill.
Mistakes We See in 10 Marla Installations
Sizing for today’s load, not the next three years. A new AC arrives, a floor gets added, a family grows. Modest headroom at purchase is cheaper than a replacement inverter in eighteen months.
Choosing capacity by plot size instead of appliance count. A 10 marla house with four ACs needs more than a 10 marla house with one, regardless of identical square footage.
Ignoring the geyser. An electric water heater can be the heaviest load in the house. Most households are better off leaving it on grid power than sizing an entire system around it.
Buying on headline kilowatts alone. Two 5kW units can differ enormously in surge rating, MPPT quality and protection rating.
Mounting in a sealed store room. Heat shortens inverter life more than age does. A ventilated position matters as much as the brand.
Skipping the surge and earthing budget to afford a bigger number on the box. This trade almost always ends badly.
A Buying Checklist for a 10 Marla Home
- Count the air conditioners that could run at the same time. This single number drives the capacity decision.
- Decide whether you want whole-house backup or essentials only during long outages.
- Confirm whether the geyser is electric, and whether you want it backed up.
- Ask for both the continuous rating and the surge rating in VA.
- Confirm dual MPPT, input current per tracker and lithium compatibility.
- Match the protection rating to the actual mounting position.
- Get the warranty term and nearest service centre in writing.
- Confirm your electricity distribution company accepts the model if net metering is part of the plan.
A 5kW hybrid suits most 10 marla homes running one air conditioner. Choose 6kW if two ACs could run simultaneously, or 3.6kW for essentials only with no AC backup.
It can run two for short periods, but a household that regularly runs both at once is better served by 6kW with a stronger surge rating.
Indicatively around Rs. 103,000 to Rs. 235,000 for 5kW and Rs. 116,000 to Rs. 285,000 for 6kW, varying by brand, protection rating and specification.
Hybrid suits most 10 marla homes, because on-grid systems shut down during outages. On-grid makes sense only if your grid is stable and bill reduction is the sole goal.
Typically ten to fourteen modules of 550W to 620W for a 5kW to 6kW system, with most hybrids accepting additional panel capacity for better winter output.
