required for those appliances.
For 38204 , with modified sine wave output, some appliances like speed controllers found in some
fans, power tools and some power tools’ AC charger may not like the modified sine wave
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 any device with the inverter, contact
the manufacturer of the device.
Estimate Run time on Load
Following run time is an estimate based on using a 12V-120AH battery bank for reference. Actual
run time may vary.

Table Lamp 40W/60W 27 hrs/ 18 hrs
Freezer (8.8 cu. ft.) 80W 15 hrs
20” LCD TV 100W 11.5 hrs
Sump Pump (1/2 hp) 350W Not applicable (surge too high)
5. TROUBLESHOOTING
To trouble shoot the unit, please note the error code display on the main unit and review the
“Understanding the Error Codes” in section 4.
Problem Symptom Solution
No AC output and
‘Power’ indicator is off.
The unit is off Turn unit ON using the toggle switch
No power to inverter Check fuse or the Disconnect switch (if
installed) is either blown or turn OFF
No AC output. ‘Fault’
indicator is ON
Unit detect fault and has
shutdown
Verify the error condition and make correction
and reset unit
Products connected to
unit malfunction or
overheat (38204 )
Products connected to unit do
not accept modified sine wave
output generated by the
inverter
Products are not compatible with the modified
sine wave output generated by inverter. See
“AC Load on Power Inverter” in Section 4. Use
