    12vdc watt meter to monitor usage over time

    TommySr - I wish I had a clue on how to use something like that. I need something MUCH simpler ... more plug and play than your suggestion but thank you!

    12vdc watt meter to monitor usage over time

    The kill a watt meter (but for dc, not ac) is what I'm looking for. Also in the price range of the kill a watt meter, not like some of the $300+ diagnostic tracking meters like I've seen.

    12vdc watt meter to monitor usage over time

    I want to measure our rv's 12vdc accessories, over time. The main one is the 12vdc compressor fridge. What's the simplest way add one between the fuse on the panel box and the accessory in the rv? It'd be simple to make a short little wire harness to adapt to the spade fuses. and, if needed, I...

    How to know if you lost 120vac power

    However, all of our outlets and appliances (outlets, TV, microwave, A/C, etc.) are live all the time because I wired them that way with the Mulitplus. So, plugging something into an outlet won't do anything for me because, if we lost 120vac to the rv, the batteries will take over and power that...

    How to know if you lost 120vac power

    The point of the small/single LED light is for it to be seen 100% of the time like an indicator light, not something that blares a loud sound so you can't sleep. I'm looking into Supervstech's idea with the relays. I just don't know anything about relays so I need to learn 1st.

    How to know if you lost 120vac power

    Yes, that is exactly what I'm looking for! However, since I'm not good at electronic crap, I don't know how to do it.

    How to know if you lost 120vac power

    I've thought of that but then when the light is out, it feels like it'd be an "out of sight out of mind" kind of thing. I'd rather the light be ON when we're running on battery. It may seem somewhat counter intuitive to some but not to me ... my brain may work differently than others too.

    Thank you. I'll look into this. Would you mind if I send you some follow-up questions if needed?

    How to know if you lost 120vac power

    I don't want it to be an audible alarm as I want to see the LED light 100% of the time when we're drawing solely off of the batteries and an alarm would get tiresome. :) It may sound stupid to some but it's just a visual saying that I'm not charging the batteries.

    How to know if you lost 120vac power

    Could you please explain how to do this? I'm a great (ok, good) mechanic but I don't understand designing circuits, electronics and programming.

    How to know if you lost 120vac power

    Any chance you could explain this in detail? Keeping in mind that I'm a competent/capable mechanic but I don't know squat about electronics.

    How to know if you lost 120vac power

    All of the outlets are hot (energized) whether or not we're on battery or shore power so that wouldn't work for us.

    How to know if you lost 120vac power

    Yes, that would be the easiest. However, to me when the light is OFF, I don't think I'd notice it (out of site, out of mind kinda thing).

    How to know if you lost 120vac power

    Through a now understood, and self inflicted, mistake, I tripped the breaker at the RV power pole but I didn't know it until we were going to bed and I happened to look at the VE Cerbo touch screen and saw we we're down to 31% SOC on the batteries. We have ... VE MultiPlus-II 12/3000/120-50 2 x...

    On/Off/Charger Only switch on MultiPlus-II

    yes it is 120v charger. If I had it plugged into the camper the Multi would be suppling the 120v to the outlet so, the batteries would be trying to charge themselves. It'd be stupid to do this, so I won't, but it is possible. I realize this isn't an apples to apples comparison but I'm trying...
