Psy1, thanks for confirming that the Victron has a fan. The images in the user manual do not show an opening for a fan.
I do not plan to run the A/C with the inverter. I am fortunate enough to camp where A/C is not normally needed. In fact, it is more common to run the heater a bit in the morning to take the chill out of the trailer.
The primary motivations for adding an inverter is the ability to make toast for breakfast (that becomes very expensive toast
), and the hybrid inverter should charge batteries faster. The Victron says it will provide 80 amps to the battery, where the original PD charger peaks at 30 or 35 amps.
Secondary motive is that adding an inverter would be an interesting project.
There is not much cost difference between the 2,000 watt and the 3,000 watt Victron units. My batteries will deliver 200 amps continuous power, which I believe translates to about 2,500 watts at 13.4 volts and 94% efficiency of the inverter. In other words I could install the 3,000 watt unit but would not get 3,000 watts out of it without adding a battery.
