  1. I looked at that thing by Midnite. It is meant for house, roof top, earth referenced systems. I don't see what good it could do on a RV. With a RV or trailer, there is no "ground" reference for it's operation. We do have to be careful with higher voltage dc, but I don't think this devise will help. Maybe John could look. Midnite site; https://www.solar-electric.com/mndc-gfp.html
  2. My solar would send at most 20 volts dc to the controller and battery. I am not concerned with GFCI on that. Some solar panels are operating at 100's of volts. That would be a problem needing GFCI.
  3. My 2000W inverter has the GFCI built into the 120 volt outlet. I connected the hard wire circuit to not be on the GFCI. It is wise to have GFCI on 120V ac. It is regulation in most building codes for some areas. Like near water or outside.
  4. If the cables from the panel to controller are sized to handle over the dead short output of the panel, no fuse is needed. Victron specks breakers on the positive and negative to enable disconnect of the panels from controller. With MPPT controller, it is important that the panels are not connected to the controller without the battery bank being connected. A heavy duty switch could handle that with less voltage drop. With my former suggestions of wire awg, I was thinking with my 12 volt brain. 48 volt can use smaller wires with less voltage drop. Fuses protect wires.
  5. Three batteries. Three 4awg cables to one bus bar. Three separate 175 amp fuses. One 4awg from the bus bar to load. Dead short in last 4awg could pull 525 amps from the bank. 4awg can not handle that. I use marine grade wire so my ampere ratings could be different than yours. Marine wire is rated at 205 degree Celsius. I would have 150 amp fuses at each battery and another 150 amp fuse at the other side of the bus bar. As breakers. The DC "interrupt capacity" is the rating you want to know. Remember a shorted battery can have tens of thousands amperes for a short time and weld the contacts in a breaker. Blue Sea, known for their quality, only have DC Breakers up to 200 amps. The panel to controller usually doesn't need fusing. There are exceptions with more than 3 panels in parallel. But a switch is good to have if needing to disconnect batteries or controller for any reason. .
  6. come on Kirk. One purpose name? Joined to day? Offering insane return on investment?. Just fishing for a sucker. The next question she would have 'what is your account numbers at that bank'.
  7. Fuses are sized to protect the wire or cable. You need a fuse to protect the wire from battery to bus bar. A fuse at bus bar to protect any change wire size. Example; 2/0awg battery to bus bar, 250-300 amp fuse at battery. 2awg bus to fuse panel, 150 amp fuse at bus bar.
  8. Netizen, you have some good answers on this over on your Reddit post.
  9. All the harbor freight crimpers are sized to metric. It doesn't matter what they say, the dies are metric. Any wire chart will let you compare metric with AWG. Some sizes are closer than others. Also, my FTZ tool has different awg dies for starter lugs or HD power lugs.
  10. I have never had problems with vehicle registration. I have had to change my drivers license in Colorado, California, and Texas. I was employed in each state.
  11. Quote; " 'Connell Virus is not conducted through 5G. However there have been 420 cases, confirmed, contacted through 4G. The only protection is submerge the 4G devise in inches of Clorox."
  12. Yes. Borrow, by force, money from SS to keep taxes down. Then discover that SS is broke and taxes must be used for those worthless retirees.
  13. DC to DC charger should be all you need, All charging sources to house bank, DC to DC to charge starter battery. Information here; https://marinehowto.com/automatic-charging-relays/
  14. There is some information here; https://nj.gov/nj/trans/vehicles/ I have a van with NJ QQ tags. I have regular liability insurance, so no mileage limits. But the state requires use only to shows and for education. It is easy to be going to a show. I can have a show. I was stopped once because I was missing a inspection sticker. No charges.
