Hi, I recently purchased your plans on the 100 watt wind generator and I have it built and ready to go, I'm just waiting on the Ametek motor to be delivered, it seems I got the wrong one, I have 37 vdc coming in, I read where you say which motors are the best and figured the 37 would work but it now seems it's one that needs more rpm to work, oh well I'll see how it works up here in Canada, my question is, 1) Do you still need a blocking diode if I'm using a Xantrex 35 battery charger/controller? 2) I also have a 600 watt wind generator, can I hook up both wires from both wind generators to the Xantrex 35 charger/controller? or should I have separate charger/controllers for each wind generators? 3) I have 3 of those big Cattepillar batteries hooked up in parallal, are these good batteries to use for wind/solar? they are all 12 volts. 4) I also am confused about the charge controller, they talk about a load diversion when the batteries are charged, if I'm using a 600 watt wind generator and need a load diversion than how am I to find a 12v 600 watt load diversion? can I not use a 750 watt inverter hooked up to a 700 watt electric heater. Thanks

Hi,
1)I believe yes you would need a diode as the Xantrex C35 I dont think has them. 2) I'm not too familiar with the Xantrex C35 but I'd say that you could connect them both together to the controller. 3)Yes these batteries would be very good since they are designed for very heavy duty. 4) You could hook the heater up to the inverter but it would put strain on the inverter and there's possible failure with the inverter. You might want to look around for low voltage heater loads or possibly make your own out of nichrome resistance wire. If you look at hugh piggotts site (www.scoraigwind.com) he has a link at the bottom for specialist low voltage heaters. I beleive that the Xantrex C35 is only good for controlling 35A so you may want to purchase heavy duty relays to run off the connections for a dumpload. |

I posted this exact same question on another forum and one guy said the batteries are consider Starter batteries which are likely very rugged, but designed to supply starter motor amps (100's of amps) for just a few seconds at a time, (3% discharge), and then be immediatly recharged by the motor. He also said for AE use, there are Deep Cycle batteries, that are designed to supply slow, draining amps, (15 amps ) for hours at a time, till the battery is 50% discharged, and then the sun comes up, or the wind picks up, and recharges them.
Catapiller batteries will last a couple of weeks or so, but not nearly as long as deep cycle batteries will last.
So it really doesn't matter,I'm gonna use them anyways, I've been told the Cat batteries are deep cycle, I can't seem to find any good info on them. I also found out that I don't need a blocking diode because there is one built in the c35, I also found a site selling low voltage water heater 12/24 v and 1000 and 2000 Watt Dump Load Resistor which is basically an air heater.

| Oh well I was assuming that the batteries were for electric vehicles but if you have them already you could try them out. |

| Ya they came off of a diesel operated loader. The mechanic who I got these from said the batteries are deep cycle but I don't think he's too sure. |

A little confused
