What size inverter do I need for a 5 kW solar system?
A 5 kW inverter. For a hybrid system, check that it also covers your peak load, the most power you draw at one moment. The load calculator shows that figure.

Solar inverter price in Pakistan (November 2026)
Inverter prices in Pakistan by rating, for on-grid and hybrid units, in standard and premium classes, with how to pick the right size for your panels and your load.
Key points
- A hybrid inverter costs more than an on-grid inverter of the same rating, because it also manages batteries.
- Size an on-grid inverter to the panels. Size a hybrid inverter to the panels and your peak load.
- Premium hybrid inverters cost roughly 20 to 25% more than standard ones.
- The inverter is the second largest item in a solar system after the panels.

On-grid, hybrid and off-grid inverters
An on-grid inverter converts solar to mains power and works alongside the grid. It has no battery connection and switches off when the grid fails. It is the cheapest type per kW.
A hybrid inverter adds battery charging and a backup output. It runs your chosen loads from solar and battery when the grid is down, and can still export surplus under a net billing agreement.
An off-grid inverter works with batteries and no grid connection at all, for sites where the grid is absent or unusable.
For how the three systems compare, see on-grid vs hybrid vs off-grid.
How to choose the rating
For on-grid, match the inverter to the array. An inverter rated at about 90% of the panel capacity is normal, because panels rarely reach their full rating in the heat.
For hybrid, the inverter must also carry your peak load during an outage: the air conditioners, pump and anything else that might run at the same moment. If your peak load is 6 kW, a 5 kW hybrid inverter will trip even if the panels are only 5 kW.
Single-phase or three-phase. Homes up to about 8 kW are usually single-phase. Larger systems and anyone wanting to export under net billing need three-phase.
What else to check
- Warranty length and who honours it in Pakistan.
- Battery compatibility: which lithium brands the inverter communicates with.
- IP rating if it will be mounted outdoors.
- Monitoring app and whether it reports export and battery state.
Standard or premium
The tables separate the market into two classes. Standard units from established brands cover most homes. Premium hybrid units cost roughly 20 to 25% more and are common on commercial sites where monitoring, service response and long warranties matter. Build either into a full system in the cost calculator.

Questions
Inverter price FAQ
02 · FAQ
What is the difference between on-grid and hybrid inverters?
An on-grid inverter feeds solar into your building alongside the grid and shuts down in an outage. A hybrid inverter does the same and also charges and discharges batteries, so it keeps running when the grid is off.
03 · FAQ
Can I add batteries to an on-grid inverter later?
Usually not directly. You would replace it with a hybrid inverter or add a second battery inverter. If you may want batteries, start with a hybrid.
04 · FAQ
Are premium inverters worth the extra?
They tend to have better monitoring, longer warranties and wider service support. For a small home system a standard inverter from an established brand is normally enough.
