Inverter fuse

Paul that is why I asked the question in post#18...its possible his batteries are low...
See if it works with his engine running..not shore power...maybe the alternator will lift the batteries V up to prove a point.

Certainly worth checking the battery voltage at the inverter, but it shouldn't be that because the OP says all lights go out.

From the manual:

Low input voltage alarm is by far the most common. When the alarm
sounds the likeness is that it is low input voltage. In most cases this is
indeed the problem (i.e. the batteries are flat). However, if the batteries
appear to be full but the alarm is still sounding then remember the alarm
voltage is being read at the Combi DC terminals (not the battery terminals).
Therefore, DC voltage measurements should be made at the DC terminal
of the Combi.

This one.

When you unplug shore power, is there an alarm, if so, what does it sound like ? Any lights stay on at all ?

When I switch the unit on all the lights come on for half a second and then all go dark again. I

Tiz why I think it would be wise to test it with the engine running and output from the alternator assistance..however ensure absolute minimum load on the inverter 220v just to test the output.
My first thought is that when the inverter demands amps the battery cant supply and the lights go off.

Sorry our posts crossed...

Do you mean when on shore power the inverter works? Od do you mean mains power available direct from shore power?

The inverter works when on shore power.

Tried this. Also the batteries are fully charged.

It does not. Read post #19.

It does. There is 12v at the input. After speaking to Sterling it is evident that something is wrong inside the inverter. Thanks to all for your

IT DOES NOT. If you read post #19 you would see that it isn't inverting when the shore power is connected, it's passing the shore power through.. This device cannot pass shore power through and invert at the same time.

Don't believe me, read the manual:

"Auto (default) - Power saver mode on
Should be left in auto under normal
operations. If shore/genset power AC is live
and connected, the charger and the through
power is active. This mode automatically
converts the unit into a battery charger and
passes power through the unit to the ring
mains. Also, when the AC input is turned off
or disconnected the unit changes to inverter
mode. "

Have you double checked that it isn't switched to charger only ?

"Charger Only
If the switch is in charger only mode (middle)
then the battery charger only aspect is
engaged. If the AC input is off or
disconnected the unit simply turns off and
does NOT automatically engage inverter
mode. "

See #15. I seriously suspect that the fact that it "blew" the 200 amp batterry input fuse would suggest an inverter fault, no? The fact that he replaced the fuse and as far as we know, that has remained intact, ( he hasn't confirmed that), would also indicate an inverter fault. Stand fast Paul for sensible input. Ignore most of the other rubbish
