AC DC Dude ,
If you knew generators you would know only one portable line keeps a
1.2% clean sine wave that is equal to or better than the grid,. It is 3
models from Honda, the Inverter line.
Unregulated gens swing normaly 35v from no load to full load with a
10+ % variance in HZ . Regulated swing 3-5% in volts and HZ. Did you
ever ck HZ on a under 7500 watt unit with a HZ meter , obviously not.
They can come new uncalibrated, They all start at the high volt - HZ and
reach 120v 60hz at 120 or suposidly rated output. Unfortunatly this
is not the case many cheap units drop even more. A 13500w 7500w
Regulated generac swings 7 % . Cheap coleman ex 35%. You need it
checked and set at your load and rechecked as they go out of set point.
Understanding safe operation and calibration is essential for all
units , its just a motor. Adjusting is easy and should be a normal
part of understanding a unit incase you will power circuits safely or
anything for longer than a few minutes.
Honda gets 2.5- 3x the price of the competition becaue of their total
package. Build, Reliability of motor and electronics and clean Safe
power output, unfortunatly few realise this and screw up apliances. Ive
yet to see a cheap gen provide safe power in 0 to full load, they just
were not made for it.
OP also should not forget to calculate extension cord volatge drop, and
dont let it run out of gas while using motors with Capacitors or the
Capacitors can easily blow.
A friend an electrician bought a new 5500- 9000w name brand during a 5
day outage at 30f , Took it home , was real happy to finaly be able to
get heat to the family. Plugged it in and in 10 minutes blew out his
new TV . He checked voltage. It came from the factory outputing 320
- 160 . After hearing of that I check everything before I use any unit.
And periodicaly recheck and adjust the governor spring . To do it any
other way is not safe.
