We live aboard, from May thru October. No shorepower, no generator, small alternator. Loads- conventional nav lights, led cabin lighting, 2kw inverter for the occasional 110v need, small chartplotter, b&w fishfinder, ancient fixed mount vhf. Dometic Coolmatic reefer system was installed in august 2015- 4a draw, 30%ish duty cycle.
Charging system is (likely, to some here, appallingly) primitive- 3 40 watt solar panels mounted flat on the bimini, always partially shaded by the boom. i panel charging a single group 27 lead acid starting battery through it's own charge controller and 2 panels charging a single group 27 lead acid house battery through it's own charge controller.
Call it $500 invested in solar and batteries.
It works. The existing charging system was more than ample, prior to the reefer install, and still meets our needs after... but with little margin. Do we NEED more charging or storage capacity or faster more better charging?
No. Our system works. If it ever fails to keep up, an hour of motorsailing will top things up.
But... there's no room for expansion. Adding a windlass, more electronics or a larger inverter would put us past the brink.
So, this winter I pulled the trigger on a 100 watt flex panel to augment the current panels, and a bigger better charge controller. Next step is increasing the house bank capacity- either a quad of 6v golf cart batteies to replace the current battery, or a second group 27.
Call it another $500.
It's not state of the art, but it works...and really, isn't that all the end result we are all looking to achieve? I'm not sure investing $1500 in an MPPT controller and LiPO or AGM batteries would give me a better ROI than our current system.

i humbly suggest that 1) you don't attempt to make your spelling errors someone else's problem, and 2) pump your brakes on your "argument" claim. He pointed out an inarguable spelling error. 3) Rethink your defensive, insufferable pomposity. It is not a good look for you.
Noice. SailFlow got his 700 clams so you vent your vitriol on me now! I may be insufferable but pompous I am not!
I'm not sure who was the object of bl's critique. I think it was Tom Scott, but it could have been Sloop. It could have been you, but I don't think so.
I know bl is normally not scattershot like this, so I'd like to give him another chance to nail the nose on the monkey, or whatever the fuck it is.
It's such a target-rich environment, rather than sorting the fucksticks from the fucknuckles from the fucknuts, I just said "fuck it" and went nuclear. Anytime anybody cites a bastardization of made up nerd bullshit from the AOL CD mailout era, to defend the failing of a self-righteous faux-martyr, someone needs to go nuclear. This time it was me. Fuck a whole bunch of Godwin's strawman ad hominem village of people better than what they write touchy-feely judgmental tut-tutting.
