Overview
About This Product
Power for heavy-duty appliances
Some places cannot afford to pause: a clinic with a dental chair, a shop with printers and a photocopier, an office with several computers, or a large home with a refrigerator, water pump and air conditioner. Chinchou high-capacity inverters deliver 2000 VA to 5000 VA of clean sine wave power, protect the battery bank with DeepSafe cut-off, and keep going through long outages.

| CHK4000 / CHK5000 | Large homes, showrooms and offices with many loads, or pump and AC combined |
Frequently asked questions
Can I run a refrigerator on a high-capacity inverter?
Yes, as long as the inverter rating covers the refrigerator's running and start-up load.
Can it run an air conditioner?
Yes, depending on the tonnage. Choose a model that covers the compressor's start-up surge, and ask our team to check your AC model.
What happens if I overload it?
The MCB trips. Reduce the load to the rated capacity and switch the MCB back on.
How many batteries do I need?
24 V models use two 12 V batteries, 36 V models three, and 48 V models four, all of the same type and age.
Which waveform should I choose?
Sine wave for computers, medical or office equipment and compressors; square wave only for simple motors, fans and lights.
Do you offer 110 V or 60 Hz versions?
Yes, for export orders. Ask us about OEM and private-label options.
