System build look good? Component list

For a sailboat, 9.9 outboards which don't require much to start but also only produce 6 amps for charging. Might keep these as a separate, isolated circuit. Long term cruising with a small dorm sized AC refrigerator, as main AC culprit although wife wants occasional hair dryer use. haha. Instruments, a freezer, multiple tablets and phones all on 12v. I may be adding more battery capacity in future as long as potentially 2 more 100w panels but for now this is what I'm trying to start with...

Already have 2 SOK 206 AH batteries on their way

about to order...

Renogy 2pcs Solar Panel Kit 320W 24V​

Xantrex Freedom XC 2000 817-2080 Power Inverter

Victron BlueSolar MPPT 150/70 Tr Charge Controller

plus applicable wiring and various bobs and bits to connect it all together. Those are the largest panels I can fit over my davits so can't go with anything larger. Might consider splitting each panel into it's own controller but not sure if it really is worth the added expense. I know I haven't given you a breakdown of how much energy I will use but I don't honestly know. The boat is a big upgrade from my previous day/weekend sailor and I plan on living with more than just an ice chest

If I was you, I'd go with a Victron MultiPlus 2kVA rather than the Xantrex. Yeah, they're $300 more, but a much better unit that will survive the marine environment a lot longer. Plus things like the power assist feature is great if you're plugging into weak/dodgy shore power.

It also lets you start playing in the Victron environment. Add a raspberry pi running Victron's Venus OS and related adapters, and you can integrate your charging, discharging, remote control, etc...

All right, just to make sure I have my head on straight....
So my MPPT will take my 24v panels and output 12v to inverter and batteries therefore I should be 12v for the inverter
this one seems to fit...
Victron MultiPlus Compact 12/2000/80-50 120V VE.Bus Inverter Charger

Love the idea of playing with a raspberry someday in the future. Definitely like the idea of better marine survivability!

Yes, the victron MPPTs will output 12v from 24v panels. That’s hope things are setup on my boat.

I’ve gone all-in on victron, so I’ma bit biased. But while they’re a bit more expensive, they actually provide good value for the dollar spent. The other nice thing is that you can build and grow your system a piece at a time as budget becomes available, due to the system modularity.

The other thing you will probably want to look at picking up at some point is a Victron Smartshunt. It will give you a good estimation of the SoC of your battery system as a whole.

You have been fantastic in your responses. I am really appreciative! Yes, I would rather spend a few more dollars now than be forced to spend a whole lot more when I am in a bad situation. Victron has repeatedly come up as reputable and reliable. I don't have any issues with your bias

I believe I had Victron Energy BMV-712 Smart Battery Monitor (Black) on my list of purchases. Lots of copper wiring (undetermined atm) some fuses, power bars, and not sure if anything else is needed to complete my build. Boat is 900 miles away but I am on my way in less than 2 weeks to go spend a month doing upgrades and then a two month trip down to Florida and around the gulf If I don't have enough power the wife will be unhappy and the trip will suck, Lol. Must have power!

You won’t regret it. I did a massive overkill install on my Ericson 27. 460Ah LFP (DIY with REC BMS), Victron inverter/charger, MPPTs, tank level monitoring, etc… while aboard I never worry about power, and when I am away from the boat, I have full remote monitoring.

We’re adding bilge depth sensors, pump control, tank level sensing (fuel, potable water, blackwater) and I can check the whole thing through the victron website.

That sure is a fun list of toys to add! I didn't realize the whole setup was so flexible. Theres a lot for me to look forward to playing with further down the road. I'm feeling much better about my revised component list. Thank you so much for all the help and ideas. Hopefully we run into one another some day

Oh, one more thing... I noticed that you have a BlueSolar on your list. Unless you're jumping right into the GX/Venus Ecosystem, get yourself the SmartSolar MPPTs, as those can be configured/monitored via Bluetooth, while the BlueSolars aren't as easily dealt with (you need either the bluetooth dongle, or to connect them to a GX device).

Ahh, my error. Smartsolar is what I should have added. Thanks. Looking at my panel selction I should be good with Victron Energy SmartSolar MPPT 150V 35 amp instead of the Victron SmartSolar Charge Controller (150V 70A Tr) I had originally planned for. I don't forsee adding any more panels to that particular MPPT. If I had roof or deck panels, they will get their own MPPT.
