solar on a bare boat- bohemian

[koyote]

TLDR; suggestions on best cheap charge controller for LiFePO and/or LA - couple hundred watts solar, possible external dc stator/alternator input, no shore power wiring needed, but might be an option to have.




I've got an older Catalina 27, outboard well model. Power is a tohatsu 9.8 which theoretically has a electric start and stator capability, but that's not hooked up.

I have running lights with bad wiring, good wiring direct to power bus (with in line fuses) for depth sounder and VHF, and cabin lights via the ancient DC panel.

Hooked up to a jackery 240 for day sailing right now. I'll be running new wire and fittings for running lights, masthead, anchor. a few DC accessories (plug and USB) and the fridge/cooler.

I have no AC power hookups, don't plan to install any. Boat came with a low end trickle charger and a 50 foot 120VAC extension cord - I'm not using that at all right now.

Haven't decided on battery, yet. probably Amazon LiFePO

What I need is the best "bohemian priced" - cheap - charge controller I can get that will handle solar and possibly stator/DC charging. Adding in an AC input plug might be okay, but not critical.

I'll be throwing a few hundred watts of solar at this over time.

Tempted to isolate the start battery completely as an independent system, with a cheap ots 20 watt controlled solar charge system. cheap, easy, and relatively unimportant.
