Premise of operation: Unit connects battery sources together if one *or* the other have a higher voltage (its a relay so when connected both batteries are wired together) Example, I have the engine battery and alternator and a house battery with solar, I want the alternator to charge the starting and house battery but not allow house loads to pull from the starting battery when engine is off (typical configuration) however, I also have a solar PV module that produces surplus power so charging the starting battery with excess power is preferred. So the house battery connects to one terminal, the start battery to the other, if the engines running the start and house battery link, if the engine is off the start battery is disconnected from the house battery *unless* the solar output pushes the house battery voltage above 12.8v, then the relay will close and link both batteries. Once the sun goes down, the relay opens separating the batteries again.
This was more a waste of my money, it was a waste of my time which I cannot get back. I am very unhappy with this. It ruined a perfectly good afternoon, then I bought from another vendor anyway to avoid this issue again.
My ML-ACR arrived and when i took it out of the package i noticed it looked used, the wiring pigtails had solder already on them and some electrical tape residue. The back of the ML-ACR had tape residue on it as well as if someone used doublestick tape to mount it the first time.
I am overall not happy that it seems i got a used product. I was in a hurry for my purposes and could not wait to get another one so I didnt mess with the return policy but I am still unhappy about it. YMMV.
I called Blue Sea and they were all over getting me a new unit ( the new unit worked as expected )
keep in mind this does not have a combine all bypass switch option it only has an option to change the drop out voltage to a lower setpoint
so jump starting yourself is not possible without using this with a battery disconnect switch
