Power inverters: what they cost in Singapore and what to check

Updated 4 November 2026

A power inverter in Singapore costs from about S$40 for a small car unit to about S$1,570 for a 3,000 W model, and a 200 W pure sine wave unit for home use is about S$135. Tell BlaBlaPrice what you need to connect, and sellers will reply with exact offers.

Voltage and what Singapore homes need

Singapore mains run at 230 V, and several listings give a 230 V output at 50 Hz, which matches local sockets. A 110 V or 120 V output will not match a Singapore socket, so check the output before you order. Input voltage matters too: a 12 V unit runs from a car battery, while 24 V and 48 V units suit larger battery banks. Add up the wattage of the devices you will run at the same time, not just the largest one.

Warranty and approval rules

Solar inverters are typically warranted for 5 to 12 years, and string and hybrid units often carry warranties in that range, so ask for the exact term in writing. Inverters connected to the grid must be approved by the Energy Market Authority and meet SP Group's technical standards for grid connection. That rule is about grid-connected units, so ask the seller which type this is. Some household electrical appliances fall under the Consumer Protection (Safety Requirements) Regulations, which list 33 categories, so check the product label.

Season, power cuts and what to write in the request

Singapore is hot and humid all year, with a wet and a dry season instead of winter and summer. November starts the wetter months, when storms are more common and a backup unit earns its place. Give the seller the input voltage (12 V, 24 V or 48 V), the wattage you need, what you plan to connect, whether the unit should charge the battery, and the city you need delivery to: Singapore, Tampines, Jurong West, Woodlands or Ang Mo Kio. Ask for the warranty term as well.
