<br />features: 
<br />
<br />100% , high quality and durable enough for your daily using.
<br />
<br />build-in industrial micro controller.
<br />
<br />one-key setting, digital display.
<br />
<br />fully 4-stage pmw charge management.
<br />
<br />build-in short-circuit protection, reverse protection, over-load protection.
<br />
<br />safety instruction: 
<br />
<br />1.make sure your battery has enough voltage for the controller to recognize the battery type before first installation.
<br />
<br />2.the battery cable should be as short as possible to minimize loss.
<br />
<br />3.the regulator is only suitable for lead acid batteries: open, agm, gel.
<br />
<br />  it is not suitable for nickle metal hydride, lithium ions or other batteries.
<br />
<br />4.the charge regulator is only suitable for regulating solar modules.
<br />
<br />  never connect another charging source to the charge regulator.
<br />
<br />system connection:
<br />
<br />1.connect the battery to the charge regulator-plus and minus. it will show &lt;1&gt;if it detects 12v battery, &lt;2&gt;if it detects 24v battery.
<br />
<br />2.connect the photo voltaic module to the regulator-plus and minus.
<br />
<br />3.connect the consumer to the charge regulator-plus and minus.
<br />
<br />**the reverse order applies when deinstalling 
<br />
<br />**an improper sequence order can damage the controller!
<br />
<br />notice:
<br />
