Operating Limits for Inverter Operation

Power Output

Temperature The continuous output rating for the MS2000 is 2000 watts or 17 amps at 120
volts AC. The MS2000 can deliver this power in an ambient (surrounding)
temperature up to 122 °F (50 °C). Above this temperature, you must reduce the
power demand or the unit may shut down to protect itself against overheating.
As with all inverters, the amount of continuous power that the MS2000 can
deliver without overheating is limited by the ambient air temperature. The
MS2000 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 it can run continuously. Operating the
inverter/charger in conditions outside of power and temperature limits 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 page4–15.
If you have problems starting certain loads, ensure that the:
•Battery connections are tight and clean
•DC cabling is not longer than the recommended length. Refer to the MS2000
Sine Wave Inverter/Charger Installation Guide for this information.
•AC wiring is of the recommended size. Refer to the MS2000 Sine Wave
Inverter/Charger Installation Guide for this information.
•Battery is of sufficient capaci ty and it is fully charged.
