Silver rectangular inverter with three universal AC outlets and ventilation slots

Samlex

Samlex SAM-3000-12 3000W 12V Modified Sine Wave Inverter

SKU CH-872Y-RJP3X

Converts 12 V DC to 115 V AC at 60 Hz, delivering 3000 W continuous and 6000 W intermittent power through three universal outlets with overload protection

  • 3000 W continuous power handles heavy loads
  • 6000 W intermittent surge starts demanding equipment
  • Modified sine wave output suits resistive appliances
  • Three universal outlets accept different AC plug types
  • Remote capable design allows convenient off-unit control

3000 W Modified Sine Inverter

The Samlex SAM-3000-12 converts 12 V DC to 115 V AC at 60 Hz with 3000 W continuous and 6000 W intermittent output. Three universal outlets accept a range of plug types. The unit is remote capable for convenient operation.

Suited for off-grid and mobile AC loads

This inverter powers tools, appliances and electronics that tolerate modified sine wave output. It is not for buyers who need pure sine wave quality for sensitive medical or audio equipment, nor for systems requiring 24 V input.

Sustained load behaviour

Continuous rating of 3000 W is maintained with overload protection active. Intermittent peaks up to 6000 W handle short surges such as motor starts. The modified sine topology keeps efficiency high during extended runs.

Questions about this item

Does the Samlex SAM-3000-12 need a 12 V battery bank to operate?

Yes, the inverter requires a 12 V DC source to supply its 3000 W continuous output.

Can I run the Samlex SAM-3000-12 from a 24 V system instead of 12 V?

No, this model accepts only 12 V DC input; a 24 V source would damage the unit.

How can I verify the Samlex SAM-3000-12 is delivering 115 V AC at 60 Hz after installation?

Measure the AC outlets with a multimeter set to AC volts and frequency; you should read 115 V and 60 Hz under load.
