Schematic ,,, âPen & Paper & Photo & Postâ ,,, not looking for âProfessional Quality here - just a chicken scratch to begin with.
FYI, this is the first post of yours on here where I actually understand your problem & why you are asking questions & that you have an Onan
,,, I feel we are getting somewhere now.
Basically you have parallel chargers operating simultaneously that are not necessarily âplaying well with each otherâ ,,, got it ,,, lets get that sorted out for you
Regarding your solar charger - what does the manual or manufacturer say about disconnecting procedures ??
I typically do not have multiple chargers running simultaneously on my 12vdc systems as I simply donât need them. But I believe âThe Forumâ can help sort out your multiple charger issue.
FYI ,,, IIRC âRenogyâ has a dual ( alternator / solar ) 50amp & a poor logic IMO of only allowing 25amps each when both are available ,,, & that is in 1 magic box
. What that boils down to is only 25amps from the alternator when on crappy solar days & driving.
So I understand you wanting to know how these things work & how to get them to play nice together.
If you get the info from your Solar Charger, you will discover the âright wayâ to stop that charger. If it is by opening the PV wire circuit get a decent â
disconnectâ;
For my remote cabin, I am considering a âCombiner Boxâ or a âBreakerâ for the âPrimaryâ function as a PV Array âDisconnectâ. Currently I have 6 100W panels 3S2P so roughly 600W ( 60 volts @ 10 amps ). I have a Victron 100 | 50 MPPT I consider the combiner box a choice for future upgrades, but...

@datdude ,,, I am bulk posting here for you to attempt a lot of info as I think you are thirsty for it. The following is important IMO in the âInternet DIYer Worldâ ,,, kinda goes hand in hand with âTrust but Verifyâ ,,, Anyway in the DIYer Van Design / Build it is like the Wild West of âBlind leading Blindâ with surface scratched just learned info & âParrotingâ without a very deep knowledge base ,,, Just do this - I did
;
So âEvenâ with a properly rated âDisconnectâ ,,, IMO, it would be âBest Practiceâ to always use that disconnect after turning the âloadâ off ,,, thus only using the ability of the âdisconnectâ under load in an emergency situation. I suppose some could fault me with that perspective ,,, but I would need to know why.
