AIMS Power 1250W 12V modified sine inverter in aluminium case with dual AC outlets and front meters

AIMS Corporation

AIMS Corporation PWRINV1250W 1250 Watt Power Inverter 12 Volt

SKU CH-M17A-S4HH3

Converts 12 V DC to 120 V AC with 1250 W continuous modified sine output, dual meters, dual fans and automatic fault reset

  • 1250 W continuous power runs demanding AC loads
  • Modified sine wave output suits resistive and basic inductive devices
  • Front-panel volt and watt meters give instant system status
  • Thermally controlled dual fans and aluminium case keep temperatures in check
  • Multiple protections with auto-reset guard against overload, over-temperature and short circuits

AIMS 1250 W Modified Sine Inverter

The AIMS PWRINV1250W converts 12 V DC to 120 V AC at 60 Hz with a modified sine waveform. It delivers 1250 W continuous power and suits off-grid cabins, mobile workstations or backup loads that tolerate non-sinusoidal output.

Check Battery Voltage and Load Type

Verify your 12 V bank rests above 10.5 V to avoid the low-voltage alarm and above 10.0 V to prevent shutdown. Ensure connected equipment accepts modified sine wave power and that total draw stays within the 1250 W rating.

Replaces Smaller Modified Sine Units

This unit steps up from lower-wattage modified sine inverters when you need more continuous capacity for simultaneous loads. The jump is worth it if your present inverter trips on overload or cannot sustain the combined draw of your AC devices.

Questions about this item

What comes in the box with the PWRINV1250W and what must I buy separately?

The inverter ships with an aluminium case, dual AC receptacles with rubber covers, a front volt meter and watt meter, dual thermally controlled fans, an RJ11 port for a remote switch and a pre-slotted mounting plate. Battery cables and a remote on/off switch are not included and must be purchased separately.

Should I choose this 1250 W modified sine wave unit or a different capacity?

Select the 1250 W model when your continuous AC load is at or below 1250 W and you can accept a modified sine wave output at 120 V, 60 Hz. Larger inverters add cost and weight without benefit for lighter loads, while smaller units will not sustain the same wattage.

What does the 1250 W rating mean once the inverter is running in my system?

It delivers up to 1250 W continuous at 120 V AC, 60 Hz modified sine wave from a 12 V battery. Expect 90 % efficiency at full load and 95 % at one-third load. Low-voltage alarm triggers at 10.5 V and shutdown at 10.0 V. Over-temperature, overload and short-circuit protections auto-reset on most faults.
