You need enough to replace what you are using plus roughly 10%


How much was that for you? I'm about to install 400 watts on my rig to get started.


1000

When you say get started that means you need to plan and research further so you don't box yourself in or buy components a second time.

I did pretty good with my original 520 watts of cynergy panels and four GC2. When I went to a resi fridge I added a second bogart controller and three 160 w cynergy. Both controllers work well with the bogart trimetric but if I knew that the system would be this large I would have used MPPT controller. 12 volt panels to work out good on my FW because they are on the edges and provide walking paths.

Portable panels..what a great idea! Set up every morning. Take down when you leave to site see or go out to lunch. Put back out when you return. Move as the sunlight moves. Put away at dusk. Fun!

I'm running led lights, resi fridge, satellite, 40 in led television. I don't invert to heavy loads so some of my heavy amps go back in during AM coffee generator time.

Regardless of what you decide to go with, one consideration that should enter your calculation is the security of your situation. A few years ago I was camping on BLM land along the Colorado River north of Yuma. An adjacent camper relayed stories about low life's stealing generators and solar panels in the southwest, particularly in the southern California/Arizona area. He had lost a generator that had been chained down with 3/8" hi test chain and knew of specific folks who had lost solar panels. (not third or fourth hand stories) I was using 2 135W panels on the ground so I paid particular attention. Depending on how far from neighbors you camp and where, it might be something you need to consider. I'm using 6 panels on my Bus but moved them to the roof quicker due to what are evidently not isolated instances.

How many amp controller are you using? The kit that is being delivered tomorrow has a 40 amp kit. 400/12 = 33, so not much cushion there and the next biggest controller was pretty expensive.
Morningstar MPPT-60. In hindsight the 45 would have been fine. You do not need a cushion with MPPT (generally). MPPT controller will limit amps to max rating. Would be very rare to actually get 400w out of 400w panels mounted flat on the roof and have battery low enough to need that much.

Looking at adding portable solar panels. Have a 2019 26 ft trailer, any ideas on how many watts i would need? And reliable brands.


Depends on how much power you use, how dead your batteries are, how much sun you typically get and how fast you want to recharge.

100 watts is a pretty common size portable setup

When figuring your wattage needs I suggest a watt meter. They’re cheap and easy to use. It gives a quick and easy way to know what several, not all, appliances require. Figure out what energy you’re currently drawing then get a larger system than you think you’ll require. I used Renogy. Their install instructions were almost nonexistent but their tech dept is really good. Especially Tylor!
