AC Load on Inverter
Although the Power Inverter can provide high surge power up to two times the rated output power,
some high surge loads like sump-pumps, heavy duty motors etc. may still trigger the inverter
protection system even though the load falls within the power rating of the inverter. A higher power
Inverter is required for these appliances.
Important: Each 3-pin AC socket provided can only handle 20A AC current. For appliances that
require more than 2400W (20A) AC Power, hardwiring to the AC Output port 3 is required.
Do not plug surge-protected power bars into the unit’s 120 VAC outlets. The surge protected
components on the surge-protected power bar may not like the modified sinewave output
generated by the inverter.
Some appliances like speed controllers found in some fans, power tools and some power tools’
AC charger may not like the modified sinewave generated by the inverter. Those appliances may
not work or may be damaged if they are connected to the inverter. If you are unsure about
powering a device with the inverter, contact the manufacturer of the device.
