Operating Limits for Inverter Operation
Temperature The Conext SW series of inverter/chargers will operate at rated
power continuously at 77 °F (25 °C) with some models capable of continuous
operation at much higher ambient temperature. However, the continuous power
rating at elevated ambient temperature may differ between models. See
“Environmental Specifications” on page 6–5 for full details. 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.
Surge Power The Conext SW series of inverter chargers feature a surge rating
of 200% of rated power for five seconds at 77 °F (25 °C). See “Inverter
Specifications” on page 6–2 for full details. Operating the inverter/charger in
conditions outside of normal rated power and temperature limits, however, will
result in thermal shutdown and/or significantly decreased performance. See
“Inverter Specifications” on page 6–2 for information on continuous operation at
higher than rated power.
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.
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
Conext SW Inverter/Charger Installation Guide for this information.
• The AC wiring is of recommended size. Refer to the Conext SW Inverter/
Charger Installation Guide for this information.
• The battery is of sufficient capacity and is fully charged.
Split-phase output during invert mode and AC bypass The Conext SW always
yields a split-phase output when inverting and during AC bypass.
• A split-phase input through L1 and L2 yields a split-phase output of L1
and L2.
• Single-phase input through L1 yields a split-phase output of L1 and L2.
• A single-phase input through L2 does not produce any output. Only the
input in Line 1 is capable of qualifying the AC coming from the power
source.
