Re: [RE-wrenches] Hydro Diversion Controls

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

Re: [RE-wrenches] Hydro Diversion Controls

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
