2.2 Power Losses
Figure 2-2 shows the power loss for
the MICROMASTER 410 Inverter.
The graph can be used to read the
loss at full load of a particular variant.

For UL compliance the maximum surrounding air temperature for 230 V / 750 W
and 115 V / 550 W inverters is 40 ºC, for all other inverters 50 ºC.
Humidity Range
Relative air humidity ≤ 95 % Non-condensing
Altitude
If the inverter is to be installed at an altitude > 1000 m or > 2000 m above sea
level, derating will be required.
Figure 2-3 below shows the permissible rated input voltages and output current for
inverter installations from 500 m to 4000 m above sea level.
