Invert Power Derating vs Ambient Temperature
The inverter/charger delivers up to 3000 watts continuous of sine wave
output to 50 °C ambient temperature and 2250 watts continuous of sine
wave output to 60 °C ambient temperature, derated linearly from 50 °C to
60 °C.
If the unit is in elevated ambient temperature above 50 °C, you are
required to reduce power draw according to Figure A-1 to avoid over-
temperature shutdown.
Charger Mode
Charger output (bulk mode) is 150 amps DC to 50 °C ambient. In higher
ambients, the charger will automatically derate (reduce output current) to
maintain internal temperatures at a safe level. Output at 60 °C ambient is
approximately 75 amps.
