I'm looking to install solar power on my boat and I have the space for 8 panels, each rated at 550 watts. Right now, I'm considering starting with just 4 48v 100 amp batteries since my budget can't stretch to 8 batteries just yet. I've seen setups like the 'Trying Not to Sink' series, and I'm interested in the Sungold all-in-one unit. On my boat, I've got two 20kw generators along with transformers to convert the voltage to 120v for smaller appliances. My main goal is to run 27 amps of AC overnight from about 10 PM to 7 AM without needing the generator. I want to optimize my setup without overspending, and while I love Victron equipment, it's quite pricey, which makes it tough to stay within budget. Ideally, I'd like to break the installation into stages that are functional, allowing me to see some benefits before adding more costs and equipment. I'm decent with wiring but unsure about the essentials versus the nice-to-haves. If anyone has pointers or tips, I'd really appreciate your input!

Have you looked into Victron's Easy Solar? It could be a great fit for you. It simplifies the installation and wiring. On the downside, it might limit future upgrades, but it could help with load spikes because you can set it between your generator and the main panel.
I agree, that could simplify things a lot!
You might want to look into the Fogstar kit; they offer both 5kwh and 16kwh batteries which could be a solid option for expanding your storage without a massive upfront cost. It’s a great way to start small and scale up as needed!
I have a pretty similar setup on my van with a 48v AIO inverter and three 100ah batteries, along with 2100w of solar. I can easily run a mini-split, lights, and a fridge overnight, often waking up with 50-60% battery left if I set the mini-split to 80 degrees. On brighter days, it charges back up by late afternoon. If you have a sailboat, maybe consider where you could install a mini-split, as I planned to do the same but ran into space issues. It really reduces generator run time at night!

That sounds efficient! How do you manage the angle of your panels on the boat?
Great setup! Do you find it tough to balance battery and solar panel output?
That sounds helpful! Have you tried the Easy Solar yourself?
