Samlex SAM-2000-12 2000 W Modified Sine Wave Inverter
Converts 12 V DC to 115 V AC with 2000 W continuous output, 90 percent efficiency, three AC outlets and remote on/off capability
- Delivers 2000 W continuous AC power from a 12 V source
- Surges to 4000 W intermittent for demanding startup loads
- Runs at 90 % efficiency to extend battery run-time
- Includes three 115 V AC outlets for multiple devices
- Protected against overload, short circuit, earth fault and low battery
12 V to 115 V Power Inversion
The Samlex SAM-2000-12 converts 12 V DC battery power into 115 V AC household power. It delivers 2000 W continuous output at 17.4 A with 90 percent efficiency. Three AC outlets allow multiple devices to run simultaneously. Remote on/off capability adds installation flexibility for mobile or backup setups.
Sustained Load Behaviour
Continuous operation is rated at 2000 W while intermittent peaks reach 4000 W. Thermal, overload, short-circuit, earth-fault and low-battery protections activate before components overheat. The low-battery input alarm warns of excessive discharge during extended use. Efficiency remains at 90 percent across the load range.
Modified Sine Wave Limits
Output uses a modified sine waveform at 60 MHz frequency with a 110–130 V range. Sensitive electronics such as medical equipment, variable-speed motors or audio gear may malfunction or hum. The DC input accepts 12–48 V, yet the inverter is designed for 12 V nominal systems. Buyers needing pure sine wave quality should select a different topology.

Questions about this item
How much heat does the 2000 W inverter produce when running continuously at full load?
At 90 percent efficiency roughly 200 W is lost as heat; the built-in thermal protection will shut the unit down if temperatures exceed safe limits.
What battery and cable setup is needed to deliver 2000 W from the 12 V input?
A 12 V battery bank capable of supplying about 17.4 A continuously, with cables sized for that current, is required; the inverter accepts 12-48 V DC input.
Will the modified sine wave output run older appliances that have universal motors or simple transformers?
Yes, the 115 V 60 Hz modified sine wave works with most resistive loads and universal-motor tools, though some sensitive electronics may require a pure sine wave source.
