<p>Product characteristics</p> <p>1.MPPT maximum power tracking technology, up to 99% charging efficiency.</p> <p>2.PV panel width input voltage 12-50V.</p> <p>3.Multi-battery type charging, support 24V, 36V, 48V, 60V, 72V Battery and custom battery charging.</p> <p>4.Built-in high-precision battery voltage monitoring function to prevent the occurrence of battery overcharge. 5.With two keys, simple and convenient operation. 6.LCD display, display content information comprehensive, concise,easy to understand.</p> <p>7.Photovoltaic panel take power technology, standby zero power consumption, night does not work, will not consume battery power.</p> <p>8.With child lock function, after locked, external battery parameters can not be set to prevent misoperation of the wrong parameters to bring trouble, child lock does not affect the digital display and parameter query.</p> <p>9.The product has a large area of efficient heat dissipation, and multi-point high-precision temperature detection, for the product, in the safe ntemperature range work escort.</p> <p>10.Charging at the same time as the city charge Charger, the controller and city charge charger do not affect each other.</p> <p>11.With current-limited charging mode, when the power of the panel is too large, the charging current is the rated current, the controller automatically reduces the charging power and makes it work at the rated charging current. .</p> <p>12. Twelve. Built-in over-temperature protection mechanism, when the temperature exceeds the set value of the device, the charging current decreases linearly with the temperature, thus reducing the temperature rise of the controller to avoid high temperature damage.</p> <p>13. Adopt metal shell, heat dissipation performance is better.</p> <p>Colour: black</p> <p>Material: plastic+metal</p> <p>Package Contents:</p> <p>1*Solar Boost Charge Controller</p> <p>(Due to different product batches, the appearance may be different, which does not affect use.)</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
