this inverter consistently lets house battery go down to 8v, until time
for the 21 day recharge timed cycle or I cycle power to force it to
recharge. I had house batt on batt#2, engine batt on batt#1 output
terminals. Seems this model maybe only watches batt#1 voltage to
decide if charge is required since it lets house batt #2 go down and
does nothing about it - until the 21day cycle comes around or I cycle
120v power to it to start over (manual says all 3 outputs are
monitored, but the reality is #2 at least is not). I just changed
house batt to #1 and engine to #2 to see if that does the trick. I
tried contacting mfgr by email but they don't seem to care to reply.
Maybe when they got bought out the new owners don't care like the old
ones did.
Seems like a mighty poor design to only watch one batt voltage for
charge level. Since all 3 outputs are tied to same charge circuit,
although it is nice to isolate the batts instead of putting them in
parallel at the charger, if one goes down and the other doesn't, it
will get the same heavy charge and possibly overheat anyway.
Does anyone know if this is how it is supposed to work?
Anyone have a recommendation of a better inverter/charger?

A combiner between the battery banks is a better solution.
Then get a charger of your choice
Charge all banks
Charge from engine or charger
No down side
No wiring of u use the isolator install

I agree - if i didnt already have a separate wire from the truecharger2
upto the engine battery. So I already have a 'combiner' while on house
juice in the truecharger2, and my engine alternator is on other side of
my old diode oem isolator....
I was more wondering if anyone else has seen this issue of truecharger2
not sensing one of its output batts going down to 8v for days/weeks on
end.

I have always had problems with combo devices. Inverter / chargers. Example. Spend a lot time trying to resolve where problems are located.
Good luck
