voltage regulator

[getterdone]

hey guys, in the past i ran across a web sight that offered voltage regulators to control alternators. i cant find it again. i need it to charge 24v battery bank, so i can equalize the bank safely. not being regulated i burned up a c 60 charge controller. dont want that to happen again.      

thanks for help!     getterdone

I have a feeling you will find the lost page if you Google

homepower mark8 24v

If not, you will find some creative solutions.  And some simple solutions.

When you're charging from the grid and paying by the KWH, efficiency matters, big time.  Lead-acids lose less power than NiFe.

Same applies when you're buying solar panels, of course.  But if you're mainly powering with a water wheel or a windmill and have sufficient water or wind resource it may be a better tradeoff to scale the genny up a bit and use batteries that waste more power but last virtually forever.

Fork lifts are used for things where the cash flow is so high that periodic replacement is a minor cost of business, while power density and a nearly flat discharge curve are assets and the batteries double as a small but heavy counterweight so lead is good.

I noticed a lot of bad links while searching. This pdf deals mainly with 12v but it may help.

OK its been a couple years now, and i still haven't got a regulator for my delco 24v 90amp alternator.
it will need to be a 3 step type.
i will be charging different sizes of battries.,600amphrs,800amphrs,1100amphrs. or altogether.
I'm not a transistor or capacitor type of guy. building it my self may not be in my scope.
I'd be willing to pay , trade , or what ever to have something that would work.
it would need to be,. self regulating. in other words, turn it on and walk away.
if your off the grid like my self. you understand the real need.
thanks to the staff and this board. with out this board my life would not be the same.

Sounds like you need one of these:

These multistage alternator regulators are popular on yachts - they allow rapid re-charge on a sailing boat where the engine's only used in the harbour - so you could look in a yachtty magazine for other makes. Trouble is, 'cos they're made for rich yachties they're not cheap.

yea they are pricey. half that much would be good. but if I'm going to spend around 4grand for new batteries, and if i can't find any other solution.,or any one doesn't have a diy
solution that can show me how. then i guess pricey is what it will be. but........i think some one on this forum has the answer there are a lot of very smart people on this form.
oh and thanks for the reply.
I've been searching the net for two days and hadn't found that listing for controllers.
thanks [ getterdone]

yea they are pricey.

They're pricey because they're marine rated.

You might try contacting the manufacturer and see if they have a less expensive model for a residential environment - or perhaps a working returned or refurbished unit that they can't resell as new but might sell you for substantially less than new retail.

Hey getterdone,

This DIY circuit looks to be worth a shot..? sure beats $180 clams!
