HI Laura, I was approaching your situation by looking at your requirements: toast and coffee in an emergency. That may be oversimplified and Will is right. You can't DIY anything close to the Titan. Here Will builds a smaller system for $1500. . Add $500 in solar panels and you may meet...

The main event this Saturday in Las Vegas is AVM vs. DVM in the featherweight division. Even money.

Have to agree with @truckoffgrid. There's a lot to be said for having sound individual components. You can find a hybrid type of controller/charger/inverter/switch. Here's an example below. If money is no object, why make it difficult? Delta 6000W Solar-Power Grid-Tied Inverter, Rule 21...

I think I've spent more time looking at your setup than all the collective time I've spent in the Louvre. Having schematics like this are great learning tools. Does anyone know of a place where more schematics are being shared?

I think, for the price, rigid is an easy decision. The flexible panels are not nearly as robust and just have issues. The rigid are cheaper too. As far as the Titan.....that's a lot of dough for a backup system. Since you're installing panels, why not build a battery bank with an inverter?

Since we're strolling down memory lane while waiting for Capt Y Knot to get some readings. A few years ago my coworkers and I were cleaning exhibits on the USS Missouri (Mighty MO) based in Pearl Harbor. After our chores were done the coordinator led us into the belly of the beast and we were...

I'm beginning to design a battery bank. Does this look okay? Totally new at this.

For a 24v system I could use an 8s2p layout.

Could you please provide the Amazon link. I couldn't find it anywhere.

Do you need the Sonoff to handle the on/off for the inverter or is that just a choice? Could you find power from another source? It does seem better to run the diesel heater from a 24v source though. Just wondering if the Sonoff could be eliminated. Not for your system, just in general.

How much for those batteries? The prices seem to be all over the place. How many amps are the transformer and lights actually pulling? I couldn't find any amp data in the specs.

I see. On my Rawson I had a 50amp alternator running to a much older type of charge controller which was charging my deep cycle house batt. It threw me off there.

Here's a wire sizing chart to get you started. Some other considerations: Series or parallel wiring for your panels, using batteries? Is the fridge AC/DC? Do you need an inverter? How cold will the wires get? http://wiresizecalculator.net/wiresizechart.htm

So you want 3 generators and solar panels to power some small appliances. Why do you need to match the generator and solar panels? You could, in theory, fire up your generators to charge up a huge battery bank. Are you planning on investing in batteries?

1. Thank you for your input. You are correct. The system I have designed will cost approximately $4400. Your option is half that. 2. Yes, balancing is top of the list. I have seen a 4s5p 180ah 3.2v system using balancing leads in the "middle" of each string using the ElectroDacus BMS. Your...

Wait. Do you mean a SOLAR generator? When you put RV and generator in the same sentence, I hear Onan 4.5kw-5.0kw gasoline generator. If you want to add a solar generator, check out Will's youtube channel. The Titan is the granddaddy. A good start is to make a list of everything you want to...

Answering one question at a time takes you closer to creating your own system. Good luck and don't be afraid to ask. That's why this forum is here!

I should have clarified my question. The unit appears to have an inverter, charger, mppt controller and switch. I'm specifically looking at the internal switching. For example, I plug 30amp service from the grid into this unit while running solar. Would this unit be able to switch the solar...

To find out how much these appliances use, look at them. Somewhere on each device you should see Input and Output. The volts and watts are almost always listed and the amps are usually listed. Here's your first formula to memorize. I live in Hawaii so I use the WAV format. Watts = Amps x...

Thank you Steve. This makes sense. I was drawing up designs that were series/parallel/series and was losing my mind. This type of design you describe would have both 24v banks of 8s cells going to their own BMS and from the LOAD of each BMS tying together on a single bus bar? Correct? This...

I thought someone would someday open this discussion. I have sailed in many conditions and have tried to put together an electrical system that could hold up in the ocean. It never happened. I know it can be done, but not with the components available to me. My last attempt was to design a...

Roger that. Based on Will's review, I was planning on using the ElectroDacus SBMS120.

When your engine is running is the Orion controlling the charge to your starting battery? From your alternator.

If you need 24v, you need to wire them in series, but contact the manufacturer or look through any instructions to see if that is okay. They are based in Los Angeles I think.

When I look at this diagram, I am confused. Does the diagram mean you

Sorry. Does this mean that you can have multiple power inputs, charge batteries and run devices at the same time? Is there a switch or is it combining power sources?

While looking over the specs for the Epever MPPT controllers I found this disclaimer. I don't see any disclaimer with the controllers 10amp-40amp. Why beginning with the 50amp controller does this disclaimer appear? "NOT FOR LITHIUM"?
