The diversion load must draw enough current to pull the hydro voltage below the absorb voltage. Use ohms law to calculate the resistance. <br>David Katz<br><br>Sent from my HTC smartphone on the Now Network from Sprint!<br><br><br><div id="htc_header" style="">----- Reply message -----<br>From: "William Miller" <william@millersolar.com><br>To: "RE-wrenches" <re-wrenches@lists.re-wrenches.org><br>Subject: [RE-wrenches] Hydro Diversion Controls<br>Date: Wed, Nov 21, 2012 12:34 pm<br><br></div><br><br></body>

<br>
I have just two micro-hydro clients, too few to have dedicated as much time <br>
as I should to educate myself. I appreciate any help on these questions:<br>
<br>
I need to rework a diversion control system.<br>
<br>
1. I am going to use a mercury wetted relay driven by the Aux relay in an <br>
FX inverter set to actuate on high battery to connect the DC Bus to the <br>
diversion load. Sound OK?<br>
<br>
2. Can I connect the hydro to the DC Bus (via a diode) using a breaker? I <br>
need OCP but I don't want anyone to disconnect the breaker and risk over <br>
speeding the water wheel. I could label the breaker "Do not open." I have <br>
been using a fuse, but if it opens, it is likely to remain undetected for a <br>
longer time.<br>
<br>
Thank in advance.<br>
