Charging batteries

My MH has a bidirectional isolator relay. Does this mean that both the house and chassis batteries will be charged when the MH is hooked up to shore power?

My MH also has a small solar charger installed at the factory. Is the solar charger hooked up to the house batteries or the chassis batteries?

My owners manual does not mention either one. Thanks ..................

If everything is working correctly, both sets will be charged.

The solar maintainer panel could be hooked up to either and/or both.

The solar panel is for the chassis battery.
The BIRD will charge the house batteries to full charge than will charge the chassis battery but always maintain the house batteries at full charge.
As long as the shore cable is plugged into a 120 volt source.

So if I am not plugged in, while the MH is in storage, and my solar panel is charging the chassis battery..... then I should expect the engine to start OK but I should expect the house batteries to lose charge??? 2004 Mountain Aire 4301

You've got the handle on it.MHO; disconnecting all batteries,is best. as running them flat ; and they will go down,even in storage mode. ; isn't good for them. Also depending on the storage area and the amount of sunlight, Chassis batteries may not stand up for a long time. Factory panel is only 5 watts. Engine/trans electronics will pull the chassis batteries down over time. 3 weeks or so.Thats all the time mine took,luckily I had disconnected the house batteries and was able to start from them.

I would think the best option is every week start it up and drive it to get the fluids warmed up and circulating, this prevents a lot of problems.
