Discharge current: 10A, 20A, 30A, 40A, 50A, 60A, 100A Max solar input: ?50V Floating charge voltage: 13.7V (defaul, adjustable) D-ischarge stop voltage: 10.7V (defaul, adjustable) D-ischarge reconnect voltage: 12.6V (defaul, adjustable) Charge reconnect: 13V Self-consume: ?10mA USB output: 2 way USB output, 5V 2.5A Operating temperature: -35~+60? Item size: 133 * 70 * 35 mm / 5.24 * 2.76 * 1.38 in Item weight: 134 g / 4.73 ounce Package size: 135 * 80 * 40 mm / 5.31 * 3.15 * 1.57 in Package weight: 165 g / 5.82 ounces Notes: 1. Make sure your b-attery has enough voltage for the controllers to recognize the b-attery type before installation. 2. The b-attery cable should be as short as possible to minimize loss. 3. The regulator is ONLY suitable for l-ead acid batteries: OPEN, AGM, GEL. (NOT suitable for nickel metal hydride, lithium ions or other b-atteries) 4. This controller can ONLY use photovoltaic panel as c-harging source, do NOT use D-C or other power supply as c-harging source. Package list: 1 * Solar Charge Controller 1 * Instruction
