Samlex SMH-5000X-12 - 5000W Modified Sine Wave Power Inverter, 12V

A contractor truck full of corded tools, a compressor, and a microwave asks for more AC than most inverters can give from a single 12V system. The Samlex SMH-5000X-12 is a 5000 watt modified sine wave inverter that delivers jobsite-scale power straight from a 12 volt battery bank, so a fleet upfitter gets real capacity without rebuilding the truck around a 24V or 48V architecture. At 14.33 pounds it mounts where the work happens: service bodies, mobile workshops, and vocational units.

Warranty

Warranty. Samlex America warrants the SMH-5000X-12 for 2 years. Full terms are confirmed in writing with your quote.

Built for Demanding Loads

Hypersurge™ starting power
10,000 watts of surge capacity spins up compressors, saws, and pumps whose starting draw stalls smaller inverters.
Efficient at work and at idle
Over 90% peak efficiency, and idle draw low enough to leave it switched on between tasks without walking the battery down.
Built for installers
LCD status display, remote control port, and 1-wire ON/OFF input, so it can start with the ignition or a dash switch.
  • Four NEMA 5-15R outlets plus a hardwire terminal - outlets are electronically fused with auto-reset, and the hardwire output feeds a distribution panel.
  • Heavy-duty DC input terminals - two 8.5 mm connection holes per terminal accept the large-gauge lugs a 500 amp draw demands.
  • ETL listed to UL 458 and CSA C22.2 No. 107.1 - vehicle-inverter safety standards for the USA and Canada.

Where This Inverter Is Used

  • Fleet service and utility vehicles - corded tools and diagnostic gear without dragging a generator.
  • Mobile workshops and contractor trucks - saws, grinders, and battery chargers running together at the site.
  • Municipal and emergency response fleets - scene lighting and equipment power that starts with the ignition.
  • High-demand jobsite and vocational units - a rolling AC supply for crews working away from shore power.
Mostly powering laptops and sensitive electronics? See the Samlex pure sine NTX series → Pure sine wave output runs microprocessor-based gear exactly like a wall outlet. Start with the NTX-400-12 and we can point you to the right size.

Ordering

Plan the DC side before you order. At full output this inverter can draw 500 amps from a 12V bank, and the DC fuse is installed externally by the user. Send us your battery bank size and cable run length and a specialist will confirm fusing and cable gauge with your quote. For fleet and volume orders, include the quantity and your delivery ZIP and a written quote follows in 24 to 48 hours.

Frequently Asked Questions

What can a 5000 watt inverter run?

Any mix of loads whose running watts stay under 5,000. A 15 amp circular saw (about 1,800 W), a jobsite air compressor, a microwave, and battery chargers can share the output at the same time. The 10,000 W surge rating covers the heavy starting draw of motor-driven tools.

Is modified sine wave right for my equipment?

For power tools, resistive heaters, work lights, and most jobsite equipment, yes, and it costs less per watt than pure sine. Microprocessor-based gear such as laptops, CPAP machines, and some battery chargers runs better on a pure sine wave. If your loads are mostly electronics, a pure sine model is the honest recommendation; if they are tools and motors, the SMH-5000X-12 is built for exactly that.

What does it take to wire 5000 watts at 12 volts?

Serious copper. Full output pulls up to 500 A, so plan for large-gauge cable, the shortest run you can manage, and an external DC fuse sized to the installation. Tell us your bank size and run length and we will confirm the details before you buy.

Can it turn on with the ignition?

Yes. A 1-wire ON/OFF input starts the inverter from the ignition circuit or a dash switch, and a remote control port supports switching from the cab. The LCD reports input voltage, output level, and fault messages at a glance.

Ready to put 5000 watts of AC on your truck?

Order online, or send the quantity, your delivery ZIP and your requested-by date and a battery specialist will confirm pricing, lead time and freight in writing, with no obligation to buy.
