Re: How to connect alternator, solar and shore power to batteries?

We got a similar setup minus the solar. Same 6x6 volt Lifeline AGM. Odyssey Blue top AGM starting battery. 100 Electrolux Alternator.
We run it through the ACR ( blue sea ) Maine suggested. Along with the bus bar also. We have an echo charger from the main bank to the starting battery. Follow Maine’s advice....he’s the expert in this area😄😄😄🤘🤘🤘🌪🌪🌪

Re: How to connect alternator, solar and shore power to batteries?

I'm sure any recent (last 10 years?) edition would cover LED lighting. The only real difference with LEDs from an installation point of view is that they are polarized, they are often voltage sensitive (depends on what you get) and they consume less power. But if you are doing a proper power consumption table, "less" doesn't matter since you'll still just be running the numbers.
Solar controllers are also a minor issue that can be dealt with on their own. Price, performance, etc. all well documented these days. Which leaves only "lithium" battery issues, and unless you're looking to spend a lot of money and replace pretty much all the charging sources (if they are not adjustable for lithium) that option is off the table for most folks.
But all of those three (LED, solar, lithium) can be explored as "minor" issues as opposed to the complexities of an entire electrical system. They're things you can decide "yes/no" on very easily, and then just chase down the details if you've said yes.

Re: How to connect alternator, solar and shore power to batteries?

On my boat I route DC to my panel from my solar charge controller load connections. All charge sources are tied to a +- buss then to the battery 40 amp breaker at battery bank and 40 amp breaker at panel.this way I have only two wires to Battery bank. I dont have a starter batt as i have a pull start out board. All charge sources need a Suitable sized diode to prevent back feeding power most do but check.

Re: How to connect alternator, solar and shore power to batteries?

@chef2sail - Thanks, yeah I definitely won't ignore Maine Sails advice.. he's the guru as far as I'm concerned. With your setup why do you have the ACR and the Echo Charger? Isn't that redundant or is that the point?

@hellosailor - Fair point(s) and I agree when you put it that way. I guess I was imagining that the books could stand to be more updated and that they could compare the pros-cons of some of the newer techs. My background is IT so I guess I'm used to manuals and texts being updated yearly in many cases.

At this point I'm thinking I'll just get the ACR from Blue Sea unless someone wants to point out a problem with that?

As it is my inherited system works but is dependent on 2 switches being in just the right position to charge both batteries. I hadn't given it any though since they're labeled and it's easy enough to remember but we just came off a 3 week trip with guests (we have guests regularly) and the guest messed with a switch and almost left us with a dead start battery during a middle of the night emergency. Fortunately I have a jump-pack that was able to get us going but the experience left a bad taste in my mouth.

At the end of the day all I'm trying to accomplish is having the house bank and the start battery always be charged from whatever source is doing the charging without worrying about switches. I think I'm on the right track now?
