Pakeage Include:<br />1 x 30/40/50/60A MPPT Solar Charge Controller Regulator<br />1 x Installation Accessory<br /><br />Specification：<br />1. System type：DC12V/24V/36V/48V Recognition automatically<br />2. Max efficiency： &amp;ge;98.1% (Voc is 1.5 or 2 times than battery， then it&amp;rsquo;s best efficiency)<br />3. Temperature increased protection: Output power will reduce when it&amp;rsquo;s more 70 centi-degree.Output power will be normal when it&amp;rsquo;s less 55 centi-degree.<br />4. Output Voltage：12V/24V/36V/48V<br />5. Charging：3-stage：constant current(MPPT)， constant voltage(Absorption Voltage)， floating charge.<br /><br />It's one kind of MPPT controller with Intelligent Maximum Power Point Tracking technology. And it also has three-stage charging optimizes battery performance and Multi-function LCD displays. Its mainly function is overcharge protection to pertect your hine.Can be mounted easily.Suitable for battery types of sealed lead acid， vented Gel， and Lithium battery.<br /><br />Notes:<br />The Load output terminal is for lamps only ( 12V system less 60W， 24V/36V/48V system less 100W )， and it will be burnt if connecting to other loads.<br />The output for battery is no polarity reverse protection.
