Pianotuna thanks for your time answering my questions just trying to learn/ understand.
In order to invert don't you need 12 volts or do you mean that you ran your batteries down before turning off the inverter causing no power for the fans to run?
From the manual....
Operation
3.9 Inverter Fan Operation
The inverter contains two internal cooling fans that are automatically controlled. The speed of these fans is determined either by the internal temperature of the inverter or by the load on the inverter. The inverter’s fans will come on under the conditions listed below:
• Fans run full speed if the internal transistors (FETS) or the power transformer reaches 80°C (176°F), or the inverter is running at 100% of its rated load.
• Fans run medium speed if the internal transistors (FETS) or the power transformer reaches 60°C (140°F), or the inverter is running at 50% of its rated load.
• Fans run low speed when the inverter is running at 25% of its rated load.
The fans shut down when none of the above conditions are met, or if the battery voltage is below 9.5V (12-volt systems)/19.0V (24-volt systems).The fans shut down when none of the above conditions are met, or if the battery voltage is below 9.5V (12-volt systems)/19.0V (24-volt systems)The fans shut down when none of the above conditions are met, or if the battery voltage is below 9.5V (12-volt systems)/19.0V (24-volt systems)
Whenever the inverter is first connected to the battery, the fans start for about one second. The inverter’s fans will not start based on temperature sensed by the optional BTS.
At times I can here my fans on low with only the batteries powering the system.
Just trying to sort this out in my head or am I missing something?
