Tripplite RV1512UL

[Ron_Nunan]

I just had the Tripplite RV1512ul installed in my van. It’s a common inverter/charger many of us have. I’m having an issue of it drawing power (2ah) constant when in the auto mode. Auto mode from my understanding allows the unit to switch back and forth between 110 and a bypass to allow shore power when plugged in.
The switch on the unit itself is similar to the remote switch many have standard on their SMB... my van didn’t come with an inverter.
My issue is that in the auto mode, I have a draw if power that’s almost equivalent to my fridge power draw.
The only way to eliminate the draw is to keep it turned off.
I get the whole idea of keeping it off when not using it but I’m more concerned something is hooked up wrong or the unit is bad.
It was new when I installed it last week even though it is 5 years old. NOS...
Tripplite told me the draw is within specs but I don’t understand why.
When nothing is plugged in, it hums/buzzed and draws 2ah.
Ideas?

Thanks

Ron, I've had 2 or 3 of these exact same units. Unfortunately they do draw some power and also hum pretty much all the time. I usually just shut mine off and flip the switch on when I need it or when I plug in. One extra step, not the end of the world.

There is a remote switch available that might save some trouble if your inverter is buried.

Thanks.., I figured it could be a common issue but find it odd it pulls so much power just sitting there.
I’m definitely going to add the remote switch.

There should be a "Load Sense Dial" just to the right of the operating switch. The factory default is usually fully clockwise, which turns the inverter on with no load. Turning it counterclockwise will increase the load needed to turn on. It will still use some power as it is in search mode, but better than being on all the time.

It is still better to have the remote switch in a handy location. Somewhere I might have the pin out for the remote control connector, if you don't want to purchase the APSRM4,

Follow up on the remote pin-out, the remote is a standard rj45 plug

• Pin 1 = + 12 volts
• Pin 2 = LED Right Side Red
• Pin 3 = LED Left Side Green
• Pin 4 = LED Left Side Red
• Pin 5 = LED Left Side Yellow
• Pin 6 = LED Right Side Green
• Pin 7 = On/Off
• Pin 8 = LED Right Side Yellow

Connect a switch SPST between Pin 1 & Pin 7, the switch on the inverter mist be set auto/remote. The inverter will default to charge only and turn the inverter on when you switch Pin 1 & 7 together.

The other six outputs are the low side for the LED Display

Thanks... I’m going to look into this because I remember turning it all the way but not sure which direction I turned it.
