Lithium Battery for Home in Pakistan

Battery size by home type

• Flat or small home (fans, lights, TV, Wi-Fi): a 24V 100Ah (2.56 kWh) runs 300W for about 7 hours.
• 3 to 5 marla home with a fridge and one AC in the evening: a 5kW (5.12 kWh) runs 500W for about 8 hours, or a 1 ton AC for about 4 hours.
• 10 marla home with one AC at night: a 10kW (10.24 kWh) runs a 1 ton AC for about 8.5 hours.
• 1 kanal home with two ACs: a 16kW (16.07 kWh) runs 2,000W for close to 7 hours.
• Large home or home office with three ACs: a 30kW-class battery runs 3,000W for about 8.5 to 9 hours.

UPS battery or solar battery?

If you only need backup during load shedding and have a 12V or 24V UPS, a matching lithium battery is the simple upgrade. See batteries for UPS (Lithium Battery for UPS). If you have or plan solar panels, a 48V battery with a hybrid inverter lets you store daytime solar and use it at night. See batteries for solar (Lithium Battery for Solar).

Where to install a home battery

• Choose a cool, dry, ventilated spot away from direct sun and the kitchen stove.
• Wall batteries need a solid wall; floor units need a level floor.
• IP21 models are for indoors only; IP65 models suit a covered porch or garage. See IP65 batteries (IP65 Lithium Battery).
• Keep children away from cables and terminals, and use a proper DC breaker.

Why lithium for home

LiFePO4 has no acid fumes, needs no water top-ups and is far lighter than tubular batteries. It gives about 90% usable capacity and many models list 6,000 cycles or more. That makes it the cleaner and longer-lasting choice for a family home.

Buying checklist for a home lithium battery

Before you order a home battery, check these points.

• Match the battery voltage to your inverter or UPS.
• Check the cycle rating and warranty years; where a value is missing, ask or check the datasheet.
• Keep the invoice and serial number for any warranty claim.
• Set the charge voltage and cut-off from the datasheet, not from memory.
• Install in a cool, ventilated spot, away from direct sun.

Write down what must run after sunset, add the watts, and pick the size from the list above. If the family plans to add an AC or a second fridge soon, size up now. Use the backup calculator (Battery Backup Calculator).
