Ask our teamWhich voltage stabilizer is best for a home AC in Pakistan?
For a single 1 to 1.5-ton AC plus a fridge and lights, a 5kVA servo (SVC) stabilizer with a 140V input range is ideal. For two ACs choose 10kVA, and for whole-home protection choose 15kVA.
Read the full guide →What is the difference between servo and relay stabilizers?
Relay (AVR) stabilizers switch voltage in fixed steps, which stresses AC compressors. Servo (SVC) stabilizers move a motor-driven slider for smooth, continuous correction within ±1% — better for motors and electronics.
Read the full guide →What input voltage range should a stabilizer in Pakistan support?
Look for a lower limit of 140V or below. Many areas of Lahore and Karachi drop under 150V in peak evening hours, so a stabilizer that only works above 170V will simply shut off when you need it most.
Read the full guide →Is lithium or lead-acid better for load-shedding in Pakistan?
Lithium (LFP) is better for daily load-shedding in Pakistan's heat. It lasts 10–15 years versus 2–3 for lead-acid, gives more usable energy, charges faster, and holds about 90% capacity at 45°C where lead-acid drops by half.
Read the full guide →How many kWh of battery do I need for my home?
Multiply your load in watts by the hours of backup you want. Essentials (fans, lights, fridge, TV) draw about 300W, so a 5 kWh bank covers 6–8 hours; add an inverter AC and a 10 kWh bank covers a full home for 6+ hours.
Read the full guide →Are lithium batteries worth the higher price in Pakistan?
Yes for most homes. Lead-acid is cheaper to buy but often needs replacing every 12–18 months in the heat. A good LFP bank pays for itself in 3–4 years and then runs for another decade.
Read the full guide →What makes a lithium battery genuine and safe?
Use LFP (lithium iron phosphate) cells from a real manufacturer like EVE, with a scannable factory QR code. LFP is the safest lithium chemistry and stays stable in Pakistan's heat — avoid unbranded grade-B market cells.
Read the full guide →What size stabilizer do I need for one AC in Pakistan?
For a single 1 to 1.5-ton inverter AC plus a fridge and lights, a 5 kVA stabilizer is right. For two ACs choose 10 kVA, and for a whole house with geyser and motors choose 15 kVA.

Which Voltage Stabilizer is Right for Your Home?
A simple guide to picking the right stabilizer size for your house — whether you have one AC, two ACs, or want to protect the whole home.
Lithium vs Lead-Acid for Load-Shedding: Which Is Worth It?
Lead-acid is cheaper today but dies in 2 years. Lithium (LFP) costs more up front and lasts 10+ years. Here's the honest math for a Pakistani home.
What Size Voltage Stabilizer Does My Home Need?
A simple sizing guide for Pakistani homes — by marla, by number of ACs, and by your actual load. Plus the one spec most people forget to check.
Will an Inverter Stabilizer Lower Your Electricity Bill?
Short answer: yes, a little — for the same reason an inverter AC saves power. Here is exactly how an inverter (IGBT) stabilizer uses less electricity.
Inverter vs Servo vs Relay Stabilizer: Which Is Best for Your Home?
There are three kinds of voltage stabilizer in Pakistan — inverter (IGBT), servo (SVC) and relay (AVR). Here is the plain difference, and which one to buy.
