Re: Xantrex Powersouce 1800 Overloading (Error E03)
Very interesting observations, thank you very much!
Guess it's running normally and I'll just have to find other backup solutions for the furnace & water pump.
Thanks again!

That is interesting. Seems to indicate that the unit is operating normally then?
Not sure how to reconcile that with it's claims of handling 1800W continuous.
The built in terminal cables don't seem that much more substantial than my booster cables (but much shorter obviously).
Perhaps that's the limiting factor?
Thank you all, for your input!...Leave a comment:

Tried retesting the 900w heater, dropped from 13.7 volts to 10.7 then cut out.
Checked the 10yr old batteries after an hour on the car and they measured 5.5 volts.

Hi Thanks for your messages.
Yes, the batteries seem to be dead, understandable since they are 10 years old.
Yesterday, tried plugging in the 900W heater with voltmeter attached and watched it drop from 13.5 to about 10.3 before overload cutoff.
Today, tried it again (in light rain) and -Surprise!- the heater ran without overloading the box. Didn't get the volt reading though - will try again later.
Thanks again.Leave a comment:

Hi thanks for the replies!
With the booster cables attached and the car running the battery reads 13.5V.
Once disconnected, it drops to 0.1.
As soon as the 900W is connected there is an overload error.
I'll have to check again to see if there is a visible voltage drop before the unit shuts off.
Thanks!Leave a comment:

Thanks for the tips on caps brands.
I understand that non-sine AC is hard on motors, but we're just looking for temporary backup for our home's main systems like water, heat, etc. in case of an outage.Leave a comment:

Hi stj, thanks for your idea! Is this testable somehow without buying the new parts in advance?

Update: Have been using the unit as described to run a small 2.5 amp jigsaw, and other small electronics (charging the laptop, phone, etc.), but any larger loads cause the overload error.
Thanks for your advice, any other thoughts out there?Leave a comment:

Xantrex Powersouce 1800 Overloading (Error E03)
Hi there, thanks for the great advice in these forums. I'm hoping to find a bit of specific advice on a Noma-branded Xantrex Powersource 1800 battery backup.
It's an old unit, with maybe 10yrs service as a sump pump backup, so the batteries inside are not holding a charge anymore, but it does still supply non-sine AC power when connected with booster cables to a running automobile's red battery terminal and engine block.
It is rated 1800W continuous and 3600W peak, but it is cutting out with an overload error (E03) with even just a 900W space heater or 1/2hp water jet pump plugged... -
