Can this unit be mounted outside to maintain batteries on utility vehicles ?

While it is "waterproof".... It isn't element proof. Aka the sun would likely destroy the plastic after a while. Including the cables etc... This is designed for charging boat batteries. Or well that's what I bought it for. Maybe someone else knows more about it.

Can this unit be mounted upside down. Where the wires would be coming out the top?

Yes. According to documentation the unit can be mounted in any position.

With a 4 battery parallel array can the 8 charging cables remain connected while the batteries are supplying the load?

The privies is to always leave the charger on the batteries. Works great. We use ours for lithium batteries. Ours are in a series, I don’t think parallel would be any different. One thing to note, it does way 40lbs.

NOCO is the next best product for your boat!

Love the this product best thing that I brought on my boat i am really loving how they have a prebuilt 5 amp fuse making easier for me to hook up and play and don’t have to go buy fuses to protect my expensive lithium batteries! On top of anything i can not say how fast it changes my battery it is kinda of heavy but, its not the end of the world great value for my money and good investment towards my boat. I loved how NOCO functionality works made it super easy for older gens and younger adults. But overall NOCO is evolution for newer boats stay safe yall!

Decepcionante

Decepcionante. Este cargador de 12 V tiene 4 salidas. Una o dos veces al día tengo que reiniciar una o dos salidas, o desconectar y volver a conectar el cargador. Se quedan inutilizables y no cargan las baterías. A veces, el estado indica un error. Otras veces, simplemente indica que las baterías están cargadas cuando no es así. Se dice que se puede dejar activado el modo de carga de las baterías y que mantendrá la carga. No lo hace sin intervención manual diaria.
