Operating Limits for Inverter Operation
Temperature The Conext SW series of inverter/chargers will operate at rated
power continuously at 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 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.
Battery power during AC bypass When sufficient AC is detected by the
inverter/charger and the battery is sufficiently charged, the AC is automatically
passed through to the loads. However, if the battery is less than 12 V (for 24-volt
models), 24 V (for 48-volt model), or had been disconnected, the inverter/
charger will not pass grid AC through to the loads.
NOTICE
EQUIPMENT DAMAGE
Do not energize and operate the inverter/charger with an AC source before
connecting a battery. Do not rely solely on AC bypass power to provide energy
to connected loads. Always operate with a battery connected to the inverter/
charger.
Failure to follow these instructions can damage the inverter/charger.
