Hey everyone! We're installing the system on our first van and have a couple of questions that we can't find answers to elsewhere. Really hoping you guys might be able to help.
Thank you, thank you
- We need to ground our house batteries, our DC-DC charger and our 1100W inverter to the vehicle chassis. Is it possible to ground the all at the same point with 3 lugs on the same self-tapping screw into the bare metal of the van?
- We're one stud short on the positive bus bar for everything we need to attach. Is it possible to connect 20A MPPT and 30A DC-DC to the same stud?
- We're using breakers as fuses; they have BAT LINE and AUX LOAD written on them. When using these between MPPT and Battery/busbar, or between DC-DC charger and Battery/busbar, should the batteries be connected to the AUX LOAD side as that is the direction current will be travelling?
- When grounding the house batteries, should the cable come directly from the negative battery terminal, rather than the negative busbar where everything else is connected?
- Finally, how should we size the fuse/breaker for the cable coming out of the starter battery for the DC-DC charger? We can't get a handle on how many amps will be leaving the starter battery.
Thank you, thank you
