Operating Limits for Inverter Operation
Power Output
Temperature The continuous output rating for the RS3000 is 3000 watts or 25 amps at
120 volts AC. The RS3000 can deliver this power in an ambient
(surrounding) temperature up to 122 °F (50 °C). In higher ambient
temperatures, if the loads draw full power for an extended period of time,
the unit may shut down to protect itself against overheating.
As with all inverters, the amount of continuous power that the RS3000
can deliver without overheating is limited by the ambient air temperature.
The RS3000 will operate and deliver its continuous power rating at higher
temperatures, but the ambient temperature as well as the input voltage
from the battery will limit the extent to which the unit can run
continuously.
The RS3000 has 7500 watt surge for five seconds. Operating the
inverter/charger in conditions outside of power and temperature limits,
however, will result in thermal shutdown and/or significantly decreased
performance. In addition, operation in this range is outside the ratings
covered by the regulatory approvals of the product. See
“Invert Power
Derating vs Ambient Temperature” on page A–6 .
Difficulty on
starting loads The inverter/charger should be able to operate all AC loads rated at or
below its power rating. Some high horsepower induction motors used in
pumps and other motor-operated equipment require very high surge
currents to start, and the inverter/charger may have difficulty starting
these loads. See “Inverter Applications” on page 4–17.
If you have problems starting certain loads, ensure that:
• the battery connections are tight and clean
• the DC cabling is no longer than the recommended length. Refer to
the RS3000 Sine Wave Inverter/Charger Installation Guide for this
information.
• the AC wiring is of recommended size. Refer to the RS3000 Sine
Wave Inverter/Charger Installation Guide for this information.
• the battery is of sufficient capacity and is fully charged.
