Re: [RE-wrenches] Hydro Diversion Controls

William, That big of a load will look like a dead short to the hydro. If you want to use the diverted energy, you need a load that draws just enough to pull the voltage down below charging voltage. You only have 50 watt to control. Get a 12 ohm 100 watt resistor or a 4000 watt 240 volt water

jay,The diversion control has nothing to do with battery current, it is to control voltage. Without it, over-voltage will occur anytime more charge current is available than the battery is accepting. A healthy small battery bank current can be as low as 0.6 amperes for flooded and AGM or GEL techno

Hi William If the hydro is only 2 amps, I would argue that you don't diversion at all. The float current expect for a really small battery bank is higher than that. So unless you want/need it for some other reason, I would not install one. jay peltz power On Nov 22, 2012, at 11:18 AM, William

David: Interesting idea. The added benefit is if the relay gets stuck, it won't destroy the battery bank. The diversion load must equal or exceed the output of the hydro, correct? The load we have will draw 38 amps at 24 vdc, the hydro will put out 2 amps. Sounds like I have enough headro

Carl, Yes, I know and appreciate that the pumps remain in production. However, I don't think there's a U.S. distributor. As my customer wants to be prepared for unknown disruptions of the social structure, telling him that if the pump fails we can get parts
