Hello, been lurking but finally need to ask a question.
I have access to park by a small turbine 24v/1000watt with charger with 24v output. If I set it up to charge my 2 batteries by putting them in series, what is the best way to get 12v power back out of my batteries (since connecting to them in parallel would cause a short)? I’m not sure if I should be looking at one of the Orion IP67 24/12 transformers or if it can be done with some kind of diode setup or other. I really don’t know the best way to get this done without putting my system at risk, unbalancing the batteries or leaking so much power it is not worth it.
"Looking at the specs on the 24/12 100 amp, it would only work when the turbine is producing >18V. "
‘it’.. .meaning the subject discussed previous to the word ‘it’. In this case ‘it’ is the 24/12 Orion. The 24/12 100 amp Orion will not work at less than 18 volts of input. You would know that if you looked at the spec. Since you didn’t know how to calculate amperage based on watts and voltage, I understand why you didn’t look up the specs and therefore know what the sentence was referring. Thanks for your help.
What kind of wattage are you expecting to draw from the batteries?
By your statement I’m thinking you’re only able to connect to the system downstream of the owners charger? Is there already a battery bank with this turbine or are you stuck pulling power direct from the turbine/charge controller?
Assuming you only have the option to connect downstream of the turbine charge control (and no 24v batteries at the turbine), I don’t believe there would be any easy way to charge 12v batteries downstream of that without letting the magic smoke out of the chargers or at least a pile of issues trying to get it to work.
How far away from this turbine’s charge controller are you able to get your batteries? Hopefully fairly close, as the voltage drop between the charger and your batteries can easily become an issue also. I think your idea of using your batteries in series and using an Orion in power supply mode to feed the 12v loads is probably the easiest method here
