There are a few folks in your neighborhood who could help get you on the right track. Forum member HarryN sells systems similar to the GoalZero but they are real 12v (he’s actually a proponent of 24v systems) and I do full custom installs mostly focusing on LifePO4 installs these days. I do have a couple Northstar takeouts from a recent LofePo4 install which I feel I may be able to revive (they are sulfated). Anyhow, to get a truly reliable system causing no system failures, and more importantly, no headaches takes some good component, thought and, and proper execution. It’s not rocket science or anything, although some make it appear to be, but some reasonable thought and planning per your requirements..

It seems like all the ports on the Yeti are only rated for 10A, and if your cable to your heater is very long there is probably a slight voltage drop, raising the amps, and going slightly over 10A. I would bet it is whatever protects it from overdischarging on that port disconnecting all the loads to the battery when the draw is over 10A on a single port.

If you can tap into 2 ports parallel that may help (probably the best option). You could also try shortening your cable to your heater as much as possible.

explanation from goal zero:

Quote:
If this heater is drawing up to 2000W from that port all at once, this may cause a sort of “whip” like you would see from a garden hose when turned on full very suddenly. That would be my only explanation for this behavior.

That being said. If you are attempting to run a 2kW heater off of the Yeti 400 you are overdrawing that battery and causing damage to it. The battery also only has a 400Wh capacity, so you should only expect a 10 minute runtime on that heater.

Heh, heh. That's a good one! Sustained 2000 Watts out of a Yeti 400!

The heater uses probably about 40 electrical watts. The other 1960 watts are heat power coming from burning the diesel fuel.

Generally they take 8-9 amps at start up and then from there very low draw to only power the fan (I believe less than 1 amp but not 100%).

Watts = Amps * Voltage

Watts = 9 Amps * 12 Volts
~108 Watts.

But if the cable is too long you may not be getting 12v to the heater, at which cause the amps pulled would increase slightly and could possibly go up past 10A, and cause you to over power the port (since all the plugs are 10A max).

I would try to connect the heater to 2 ports in parallel which should split the load a little bit across them. Similar to how the cable works from the other post.

interesting
how would I do the in parallel? take the single cable and wire in a second cable at the end with 2 more terminals and add that to my fuse panel in the normal way except 2 black terminals and 2 red terminals?

actually what I said wouldn't do anything because that connects to one cable that goes into the single Anderson port.
I guess what you're saying is take the one cable coming off the fuse panel leave the Anderson port then splice in a second cable right before it that goes into like the cigarette lighter port?

would it be a bad idea to just tape the Anderson cable into the yeti so that it doesnt jolt out when the heater cranks on? would that start a fire or damage the battery or something? I dont know enough about electrical to understand
