I am trying to eliminate running the engine and genset at the same time. I have a 2500 watt rv series(rv2512) inverter charger, a 9200 series (9280) intelli-power converter, a 200 amp battery isolator, and a 200 amp continuous duty solenoid. I dont think I need all of this, depending on how I hook it up. Also, this is not on my coach, it is on my rig.
1st off, I have a total of 9 batteries on this unit. 6 are engine starting batteries, 2 are house batteries(2 6 volt connected in series for 12 volts), and 1 battery for starting the genset. At this moment, I have the inverter charger set up to charge the house batteries when the genset is running...or invert when genset is stopped. The genset will also charge the starting batteries and genset battery. It doing this through its own isolator setup (from factory).
While driving down the road, I want to be able to charge the house batteries with the 200 amp alternator or the intelli-power. My thought is 1 of 3.
1) Run a 2/0 wire from the alternator to the 200 amp continuous duty solenoid...then from the solenoid to the house batteries. And then wire a 14 or 16 guage wire to an on / off switch to engage the solenoid.
2) Run a wire from the engine batteries to the isolator...then from the isolator to the house battery and genset battery.
3) DONT KNOW IF THIS WOULD WORK OR NOT!!! If I install the intelli-power, one hot and ground to the engine batteries...the other hot and ground to the house batteries. Plug the intelli-power into a 20amp recepticle, When I am driving down the road, the inverter is on the intelli power would charge the house batteries constantly ans well as charge the engine. "WILL THIS INTERFERE WITH THE ALTERNATOR OR INVERTER???" I know that if I am sitting with shore power hooked up, it would charge the starting batteries and house batteries, which is what I am also looking for. sorry for the long post...just wanted to make sure it is well understood what I am trying to accomplish!!!

Bill,
Can I ask some questions before I have to answer? Are your 6 engine starting batteries in three groups of series-parallel, (12V start) or is the rig 24V start?
If you are all 12V, MY suggestion would be to keep it very simple. Put the isolator between the rig alternator, and the house batts on one side, chassis batts on the other side. OTR, you are charging both sets with a good quick charging system. Connect the inverter to the house batts, obviously. On shore you get house charging, and on gen, you get everything charged.
In MY opinion, a 200A alternator and a seperator is THE way to do batts. From MY personal sad experience, a seperate gen starting battery doesn't last well, due to lack of use and in MY case, charging. (It was only charged by the gen.)Now, YOU may want to say, "I want some redundancy in my starting circuit," and use the gen batt to help start, (if you're not 24V.) Your 200A solenoid comes into play here, between the chassis, and the gen batts. A single pole, double throw toggle switch, on, center off, momentary. COMMON term hooked to the coil of the 'noid, ON hooked to the ignition on, MOMENTARY to a gen batt hot. ON has the gen batt charged by the chassis alt, MOMENTARY held over will use the gen batt to help the other start batts, in time of need. On, with the key on, will have the chassis batts help the gen batt. All batt negatives grounded.
Your inverter MAY look at you funny, when seeing a battery being charged by another source, but as Don said yesterday, "It may not."
If you use the solenoid to charge the house batts, you may forget to turn the switch off, and run everything down. You can wire the solenoid coil thru the ign side of the ign switch, but isolators never forget.
Good luck,
George |

Thanks for the reply George
I have a 12 volt starting system. How would I get the chassis batteries charged when parked and on shore for a week or 2(during vacation time)??? Isn't this where the intelli-power come in to play???
