SOURCE: Xantrex Freedom 458 Combi inverter/charger 2000 watt

OK my 2000 Discovery does the same thing. Try and hit the inverter charger with your fist 3-4 times, then listen and see if the charger fan starts up. I will be bringing my inverter to Portland this week to have the tech look at it. The other thing is it could be the transfer switch. Will let you know.

SOURCE: I have an old Heart Freedom 20 charger/ inverter.

I have had a Heart Freedom 10 for over 10 years and have found it to be very reliable though slightly lacking in power if th a/c (just plugged in to fwd AC breaker)is on and I lose shore power or gen..
As MT1 says apply AC power to your main input then check the cooresponding pop up circut breaker for pwr in and through. your should get a transformer hum if power is getting to it and a depleted battery is hooked up. If you have a charged battery and a link you should get a led light and or a fault code of either a sequenced blinking light or a readout on the better remotes.
If this is not avilable just check all of the installed breakers for continuity before sending it in for repair as the shipping alone to and backwill be approx.$100.
Good luck. I am looking to upgrade to a freedom 20 now. There is a sell price on the net of $864.

SOURCE: inverter won't charge

The problem is the batteries. 1) Check the age of them to assure they are not near warranty limit. If so change them. 2) They must be topped off. I recommend using distilled water within every 30-60 days. Summary: After doing item 2 above charge them with an external charger; while connected to inverter is ok. Does this help?

SOURCE: I got an error of ER 05. What does that mean?

Hi and welcome to FixYa, I am Kelly.

E05: Flashing Fault LED: Flashing Alarm: Beeping = Output on inverter is shortcircuit

- Disconnect your output terminals and see if you still have the code. This is telling you there is an external short.
- If you still have the error with the output terminals disconnected start looking for internal inverter shorts to the output connector. (Chaffed wire / hot wire signs / internal + lead ground)
- If you have Circuit Breakers / fuses on your output side open all the CB/s or remove all fuses then turn on the CB's / install fuses one at a time until you note the Er05 error. Then troubleshoot the shorted circuit with an Ohm Meter.

Thanks for choosing FixYa,

I have a customer that recently replaced his generator, problem is , he got a 120 VAC output. He has 2 SW 4024 for 240 VAC output. Can I hookup the 120VAC to the master inverter, or should I get a...


I will accept the second option which is getting transformer.

Go ahead and get a transformer in order to step up the voltage. This is better than hooking up the 120V AC to the master inverter.

In summary, get a transformer to step up the voltage.

I hope this is clear now....

Good luck.

I am trying to fix my xantrex freedom 10 inverter/charger but I need the internal wiring diagram. Is there I way that I can get it?

Unfortunately, to protect their proprietary designs, Xantrex does not provide parts or schematics except to their factory authorized service network. Assuming it is not still under warranty that would be voided by removing the cover, you might be able to see any obvious damage and procure the necessary repair parts from a third party, but that might be a lot of trouble to track down without any guarantee that it would actually fix the problem. If the unit cannot be uninstalled and/or brought to a service center, some reps do make "house calls", albeit for a fee.

Inverting side working fine but charger is not

I had a similar problem at work yesterday.when your charger switches of it assumes that the battery is fully charged, while it is not.this is the solution , switch on you inverter machine and allow it to run, while it is running use a direct current "dc" multi meter a test the voltages of the batteries any one that drops like 3 volts below the normal voltage is bad. Change it and you will notice that the problem will stop. Note that when a battery is bad it takes little time to get it charged than when it is in a good condition .

Xantrex 458 freedom....has stopped charging house batteries off of engine alternator. Alternator is showing that it works (dash gauge). It does charge while on shore power or generator....but not charging...

Fis\rst of all is the inverter supplying 120 VAC? when turned on?. If so the inverter seems to be working.I think your problem is in the truck alternator/charging system. The inverter is independent of this charger..
