Voltage Stabilizer Selector
Add the appliances you want to protect and we'll calculate the correct kVA rating (including motor start-up surge and a safety margin) and recommend a stabilizer.

How is this calculated?
- Each appliance's watts are converted to apparent power (kVA) using a typical power factor for that appliance type.
- All running loads are added together.
- Motors (fridges, ACs, pumps, washers…) draw a big surge when they start. We add the start-up surge of the largest single motor on top of the running load — or of all motors at once if you tick the worst-case box.
- A safety margin is applied for headroom and future appliances.
- We recommend the smallest stabilizer in stock that meets the requirement, plus a larger option for extra headroom.
Disclaimer: This is an estimate to help you choose. For permanent installations, motor-heavy or industrial loads, please confirm with a qualified electrician.
