Rv inverter charger problems series#

I know you have run some of them and a yes, no, a voltage or other response to the item list will sure help get everyone on the same page:ġ- You replaced all 4-Good starting base line.Ģ- The AC and refrigerator worked until the voltage dropped to 10 volts. There is a bypass relay in the unit, this allows you to have AC power to the 2 circuits running from the inverter when it is turned off.Īllot of things going on, so I created a list to work from so all know what and where tests have been made.

The fact that the 4-6 volt batteries are connected in a series / parallel configuration, one bad cell in one battery will drain the batteries. Helps me have a better understanding of your skill sets. Good to know that you are a Ham operator.

It seems we have not had 120 in the coach since the charger stopped functioning.Īnd, yes Rich, I am a Ham Radio Operator ( W3WW ) I am going out now and run the engine and charge the batteries turn on the inverter and check for 120 at the outlets. Would two possibly bad batteries out of 4 cause the charger to not function. The Interface panel inside was showing the charger was on and working. The green charge light was working on the front of the 458, no red lights. I took the battery cable covers off the inverter/charger and noted 9.5 with the charger on and off. The Heart Interface Panel in the coach was also showing 9.5.

Total was around 9.5 at the point of going to the inverter/coach. After 8 hours two were at 5.65 and two were at 3.85 Volts. At that point I checked each of the four batteries and they each were at 5.97 Volts. ( that was after charging the batteries from the engine alternator). I checked the big fuse with a Multi Meter and from each side of the fuse to ground was 12.7 Volts thus I presume it is OK. Refrigerator works on Electric until the voltage drops below 10.0 on batteries. It works with shore power until voltage drops, which I believe causes the wall thermostat to give up. The fuse on the front of the 458 was not 'pushed out' or did not need re-set.

I checked (flipped) all circuit breakers and none seemed open. I thought I may have had a bad battery cell, but now I'm not so sure.Īny suggestions would really be appreciated. I have cleaned most of the battery terminals particularly the one tied to the charger. This fuse is behind the batteries bolted to the wall directly behind the Batteries. Battery state shows correctly on panel.Ĭould the huge fuse between the charger/inverter be blown ? How would I check it ? That fuse is between the charger and battery bank ( Four Newer- 2 year old Crown 6V in series ). Checked all circuit breakers and no apparent problem there. On the front of inverter green charge light is on. When hooked to shore power control panel far right LED says 50 amps incoming breaker, on far left AC IN LED on, charger light on. I shut everything down except I did not put it in storage mode. This morning 12 hours later they were at 11.7 with only the systems I don't know about running. Last night batteries were at 7.8 volts and running engine 15 minutes brought them up to 12.8. They will charge from running the engine via the alternator. Newer Lyght LPT-50 Transfer Switch, Freedom 458 20D Heart Combi inverter/charger with the Heart Interface Remote Control Panel.īatteries will not charge from inverter/charger on 50AMP shore power or Generator. I have a 2000 Dutch Star 38' Cat Engine on a Freightliner Chassis. This is my first post and out of desperation.
