The inverter’s AC (“modified-sine wave”) output waveform is designed
to function similarly to the sine wave shape of utility power. Most AC
products correctly rated for the power rating maximums listed in Table 3
or less will operate normally with the inverter.
Operating loads with high surge requirements
The power, or wattage rating, of AC loads is the average amount of
power they use. Some appliances consume more power than their power
rating when they are first turned on. TVs, monitors, and electric motors
are some products that have high surge requirements at start up. The
inverter can supply momentary surge power that is higher than its
maximum power rating. Some products rated less than power rating
maximum for your inverter may exceed its surge capability and trigger
an overload shutdown. If this problem occurs when attempting to
operate several AC products at the same time, try first turning on the
inverter with all AC products turned off, then one by one turn each on,
starting with the high-surge product first.
