Freedom 20 Inverter/Charger Overload will not reset.

Question edited for clarity. Error is zero-3 not letter oh-3.

There are three models, an your load has exceeded its capacity

E03 AC output overload shutdown Reduce the loads connected to the AC outlet of the unit. Check appliances that have high-surge ratings and disconnect if necessary. NOTE: This could be a logical fault, hard reset and reassess the error condition.

Second Freedom 25 inverter/charger...first one repaired, this one went to fault...started microwave on fire, fried the satillite receiver and possibly other components....installing a Mangnum....."do not let anyone rebuild the Freedom 25" First time about $900.00 to rebuild...this time about $9000.00 with components it fried. Fleetwood LLC Corporate knows of problems and only offer to sell you the conversion kit for about $4200.00....bankruptcy sanctifies previous problems "they" left with us.

The charger has four distinct charging stages - 1) Bulk, 2) Acceptance, 3) Float, and 4) Equalization. If your batteries are old and therefore won't reach full charge, the charger may not be able to get them up to the voltage where float charging kicks in. If you ever allowed the water in the batteries to get down to where the plates were exposed, one or more of your batteries may be contaminated with excessive sulfate buildup on the plates. The equalization process (Stage 4,which must be entered manually) will help to return any excessive sulfate builup back into solution, so you might try that and see if the performance improves.

Go to the Xantrex website and run through the support section. Then look up the closest service center.

The fan can be replaced. It is very similar to some of the PC cooling fans. I've got the same problem (again) and will be replacing it soon. I will give you the fan specs once I remove my fan ( I think it is 4" 120VAC - will let you know when I repair mine).

check if the inverter has a fuse for the charger, if it does test it if it is still ok if not change it

1997 monoco dynasty and the invorter heart interface freedom model 20 the problem we are having is the we don't get any powere from the electric outlet and the lights don't work and there is a reading in side on wall that tells you about your electricity and it reads overload my # 817-614-7576 donna

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.
