Solar Battery Backup in Karachi, Sized for Your Load-Shedding Hours
Get Free Quote WhatsApp UsLithium Battery Backup Built Around Your Outages
Solar battery backup keeps your home or business running when the grid goes down, and in Karachi that means planning around load-shedding, not around a brochure. SunnyPath Energy sizes every battery system to two numbers: how many hours you lose power, and which loads you actually need running in that time.
We install lithium (LiFePO4) batteries by default. They last longer and need far less maintenance than lead-acid, and they can be added to a new hybrid system or to an existing one, whether we installed it or not.
Back Up What Matters, Not the Whole House
The most common mistake with battery backup is sizing it to the whole house. Running every air conditioner through an outage needs a very large, very expensive battery bank. Running lights, fans, the fridge, internet and a few essential sockets needs a fraction of that.
We start by listing what has to stay on, for how long, and build the battery around that. Options run from a single standard battery up to 16kWh of storage for extended runtime.
Batteries From Brands We Stand Behind
SunnyPath Energy is a Partnered AEDB Certified (Category C1) solar EPC company with 550+ systems installed across Pakistan and 225+ inverters repaired. We supply and install lithium batteries from Dyness, Sunwoda, BYD, Fronus, Crown, Ziewnic, Inverex, MaxPower, Huawei and Solis, and we check every battery against the inverter it will run with before anything is ordered. Every installation includes 1.5 years of free after-sales service on top of the manufacturer warranty.
Want Solar Charging Your Batteries Too?
A battery on its own only stores grid power. Paired with solar panels and a hybrid inverter, it charges from the sun during the day and carries you through the evening and through load-shedding. Our installation team sizes the full system around your K-Electric bill and backup needs.
How We Size a Battery Backup System
Lithium Battery Backup Solutions for Homes and Businesses
Battery sizing is where most backup systems go wrong in Karachi: too small and it runs flat halfway through an outage, too big and you have paid for capacity you never use. We size yours in four steps.
- List the critical loads. Lights, fans, fridge, internet, water pump, and anything else that must stay on.
- Match your outage hours. How long load-shedding lasts in your area, and how often.
- Check the inverter. The battery voltage and communication must match your hybrid inverter, or a new one.
- Choose the battery. A lithium (LiFePO4) model from a brand we stock, from a single standard battery up to 16kWh.
You get a quote for the battery that fits those numbers, not a fixed package.
Why Lithium Instead of Lead-Acid
Lithium (LiFePO4) batteries cost more up front than lead-acid, but they last considerably longer, can use more of their stored energy, need no water topping-up, and handle the daily charge-and-discharge cycle of a solar system far better. For a backup system you expect to rely on for years, that is why lithium is our default.
Already Have Solar? A Battery Can Be Added
If you already have a hybrid inverter, a lithium battery can often be added to it without replacing the system, as long as the voltage and communication match. If your current inverter is on-grid only, we will tell you plainly whether adding storage makes sense or whether a hybrid inverter is needed first. Adding a battery, for example a 5kWh lithium battery, is quoted as the battery price plus installation, with no additional or hidden charges.

Frequently asked questions
01How big a solar battery do I need for load-shedding in Karachi?
The right solar battery size depends on which loads you need running and how long your load-shedding lasts. SunnyPath Energy lists the critical loads, such as lights, fans, fridge and internet, matches them to your outage hours, and sizes the battery to that, with options from a single standard battery up to 16kWh of storage.
02Lithium or lead-acid: which battery is better for solar?
Lithium (LiFePO4) batteries are better for most solar systems. They last considerably longer, can use more of their stored energy, need no water topping-up, and handle daily charging and discharging better than lead-acid. SunnyPath Energy installs lithium batteries by default.
03Can a battery be added to my existing solar system?
A battery can usually be added to an existing system that has a hybrid inverter, as long as the battery voltage and communication match the inverter. If the system has an on-grid inverter only, a hybrid inverter is normally needed first. SunnyPath Energy checks compatibility before quoting.
04Which battery brands does SunnyPath Energy install?
SunnyPath Energy supplies and installs lithium batteries from Dyness, Sunwoda, BYD, Fronus, Crown, Ziewnic, Inverex, MaxPower, Huawei and Solis, and checks every battery against the inverter it will run with.
05How long does a solar battery last?
A lithium solar battery typically lasts many years longer than a lead-acid one; the exact life depends on the model, how deeply it is discharged and the temperature it runs at. The manufacturer warranty for each battery is listed on its product page. Batteries carry the manufacturer's warranty. You can claim it directly with the manufacturer, or SunnyPath Energy can handle the claim for you for a service charge.
06How much does a solar battery cost in Karachi?
Solar battery prices in Karachi depend on capacity and brand. SunnyPath Energy lists current indicative prices for every battery in its shop, from small 12V units to 16kWh systems, and confirms the final price on quotation after sizing the battery to your load.
