    these items instead of the "kit" for 5th wheel.

    You can parallel strings without fusing as long as the short circuit current doesn't exceed the panel rating. In most cases, you can parallel two strings without adding individual string fusing because the short circuit current of one string is less than the fuse rating on the panel. In most...

    need advise for 24v 300A breakers

    Agreed as long as the correct type of OCPD is being used.

    need advise for 24v 300A breakers

    What is the surge rating on the inverter? Fuse and wire size should account for the surge rating. Usually the inverter manufacturer has a recommended time delay fuse size. I would suspect that a 2000W inverter will be able to surge to 3000W. Usually a 2000W inverter at 24V will be best...

    Small solar panel system

    I also think companies like Wholesolarsolar build little kits like this for people for these small applications. You have to get in touch with a salesman. It isn't the least expensive way to go though.

    need advise for 24v 300A breakers

    I second this motion. Use a fuse. You should never have a fault on a line that large that should just be reset. If you blow a 300A fuse or circuit breaker that was sized properly, you should investigate the fault and not just reset the breaker. Use a fuse with a separate disconnect switch if...

    PV panel water heater idea

    I think the technology has never taken off because its a bit complicated and doesn't "pencil" for residential and/or commercial applications. There are some companies making the product though. Dual Sun

    Charge wire in 7-way trailer plug and lithium battery

    I'd estimate about 10-15 seconds. Amperage was holding steady.

    Charge wire in 7-way trailer plug and lithium battery

    Well sorry for the LONG delay. I finally got around to doing this testing. I tested this on two separate trailers yesterday. One of this trailers is a single axle that I built with brakes and the other was a 23' camper trailer that I was converting to lithium. Both trailer brake systems...

    Building out my system, where/how best to tie B2B in 2019 Sprinter with Aux Battery?

    I would not tie directly to the power terminals under the drivers seat. I don't remember what the body builders manual says but I would not personally put more than a 10amp load on them.

    Building out my system, where/how best to tie B2B in 2019 Sprinter with Aux Battery?

    The NCV3 with aux. battery option should have a battery isolating relay installed under the drivers seat. There is also a connection point here for running items off of the factory auxiliary battery. I would strongly recommend against tying into the auxiliary battery system. Mercedes also...

    RV inverters for 50 amp shore line trailers.

    Okay...that makes a lot more sense now. I missed your earlier post about the power pedestal. I haven't considered this solution because it isn't universal for all RV parks or shore power hookups. It certainly is a cost effective solution! I would imagine that you could need the inverter...

    RV inverters for 50 amp shore line trailers.

    I'm sorry to have upset you. I wire RVs for a living so I have quite a bit of knowledge of how RVs are wired and how shore power works. I think I am just asking a different question. Perhaps you have come up with a solution that might help me in the future...that the point of this forum...

    RV inverters for 50 amp shore line trailers.

    I am assuming that you rewired your RV to only use one of the legs of the 50A shore power connection when you plug in. Is that correct? That would be the only way that your Multiplus 4k/48 would be able to supply everything in your RV.

    RV inverters for 50 amp shore line trailers.

    You have several options to consider with this situation. 1. You can purchase 2 inverters and configure them to output in a split phase configuration. You will have some limitations when running on your generator because your generator is probably not split phase. There is some rewiring to...

    Best solar panels for PNW winters.

    I am up in central Washington. I think more important to your situation is going to be how you wire them for low light performance and keeping them out of shade. If you mostly park in the same place, you can place panels and wire them for better performance. If you have a large RV, place...
