How do I choose the right power inverter for the appliance I need to run?
Check the appliance rating label; it should be listed in Amps or Watts. If rating is listed in Amps, multiply the Amps by 120 volts. The answer will be the watts required. This number should be lower than the continuous wattage rating of the inverter. -
A 300 watt inverter providing 150 watts connected to a fully charged 100 reserve minutes battery will last approximately 2 hours. 15 amps/30 = 2 hours The higher the "reserve minutes" the longer the power inverter will work.

How long will the power inverter run on batteries?
The inverter will run continuously if: The battery(s) voltage maintains 11 volts(10.5 volts for GO-AC models) or higher (15.5 volts max 16 volts max for GO-AC models). Sufficient air spacing and ventilation around the inverter Not unusually high air temperatures (90+) Wattage is below continu... -
How much power does the power inverter need from the batteries?
As a rule of thumb (leaning on the high side), an inverter will require 10% of its continuous wattage rating from a battery. Example: A 300 watt inverter providing 300 watts to an appliance will require 30 amps from the battery. The same inverter providing 150 watts to an appliance will require 1... -
The power inverter will not run my appliance (TV, microwave, etc.)
IMPORTANT: Before operating medical equipment, such as a nebulizer, check with the medical equipment manufacturer. Majority of medical equipment is not compatible with modified sine waves. Please check with the appliance manufacturer to see if it is compatible with a modified sine wave output f... -
What does it mean if the overload or red light illuminates?
This is an indication that the inverter has shut itself off by: Low or high voltage input (<10.5, >15.5 [GO-AC models <9.5, >16]) Thermal shutdown (unit overheated) A start-up surge higher than the peak wattage of the inverter A shorted appliance The unit may be defective if the ... -
What if the power inverter works fine but shuts off (red LED on) when engine runs?
At this higher voltage, start up current for the device along with engine noise produces a false overload condition. Simply leave device switched on, turn the power inverter off then back on. This should solve the problem. -
To produce AC from 12 VDC a couple of steps or conversions take place inside the inverter. First step is the input voltage (12 volts) is increased to 145 VDC. Step two, the 145 VDC is converted to 110 VAC by using advanced MOSFET transistors. The resulting AC output from this conversion is called...

Why does my voltmeter show less than 110 volts?
For accurate measurement of the output voltage of the inverter, a voltmeter with "True RMS Voltmeter" marking on it must be used. Typical brands of this voltmeter are; Fluke 87 and 8060A, Beckman 4410 or Triplett 4200. If your voltmeter is not one of these brands or does not have a "True RMS" mar... -
Will my power inverter run a nebulizer, medical equipment, etc.
IMPORTANT: Before operating medical equipment such as a nebulizer, check with the medical equipment manufacturer. The majority of medical equipment is not compatible with modified sine waves which the power inverter uses.
