Samlex America Evolution F Series 1200W 120V 24V 40A Inverter Charger

SKU CH-31W2-9JMZB

Pure sine wave inverter charger delivers 1200W continuous power from 24V input with 40A charging and zero-transfer-time switching

  • Brand nameSamlex America
  • Pure sine wave output protects sensitive electronics
  • 1200 W continuous power runs demanding AC loads
  • 40 A adaptive charger extends battery life with six programmable profiles
  • Zero-transfer-time switch keeps loads running during source change
  • 3X surge capacity handles motor start-up spikes

Industrial Pure Sine Inverter Charger

This Samlex Evolution F Series unit delivers 1200W continuous pure sine wave output at 120V from a 24V DC source. It integrates a 40 amp multi-stage battery charger with six programmable profiles for lead-acid or lithium banks. The built-in transfer switch provides zero transfer time when AC input returns.

Mobile and Backup Power Installations

Designed for boats, RVs, cabins and specialty vehicles needing reliable off-grid AC power and adaptive charging. Installations requiring a different DC input voltage or a higher continuous power rating will need alternative equipment. The hard-wire connection suits permanent mounting rather than portable use.

24V DC Input Voltage

The inverter charger operates exclusively from a 24 volt battery bank, making this the primary specification that determines compatibility with an existing electrical system. Verify that the installation provides a 24V nominal source before purchasing.

Questions about this item

How do I install the 24V input and hard-wire the 120V AC output on this inverter/charger?

Connect the 24V DC source to the input terminals with correct polarity, then hard-wire the 120V AC output to your distribution panel using appropriately rated cable and an overcurrent device; the step often missed is torquing the DC lugs to the specified value so the 40A charger current does not create a hot spot.

What maintenance will the 40A battery charger require over time?

Periodically inspect the DC connections for corrosion, verify the cooling vents remain clear so the charger can sustain its 40A output, and re-run the adaptive algorithm if you change battery chemistry between lead-acid and lithium profiles.

At what point does the 1200W continuous rating limit sustained loads on the 120V output?

The inverter delivers 1200W continuously; loads above that level will trip the protection after the 3X surge window, so the 1200W figure is the first hard ceiling you hit during extended operation.
