100A MPPT Solar Charge Controller Dual USB LCD Display Auto Solar Cell Panel Regulator

Please note this item ships from an international seller. Expected delivery is 10-15 days. As the most high-end and advanced solar charge controller it charges the battery with the max power MPPT tracking efficiency is 99% and the whole system has a high power generation efficiency of 97%. Features: This product provides short-circuit protection open-circuit protection reverse protection overload protection. Automatic focusing MPPT tracking charging high charging efficiency non-stop detection during charging bidirectional focusing tracking. MPPT solar controller can detect the voltage and current of the solar panel in real time and constantly track the maximum power so that the system can always charge the battery with the maximum power. The tracking efficiency of MPPT is 99% and the power generation efficiency of the whole system is up to 97%. Moreover the system has excellent battery management including MPPT charging constant voltage average charging and constant voltage float charging. Specifications: Battery voltage: 12V/24V Auto Adapt Material: ROHS+ABS Item color: blue+black Charge current: 30A 40A 50A 60A 100A (optional) USB output: 5V 2A Item size: 170 * 95 * 40 mm / 6.69 * 3.74 * 1.57 in Item weight: 260 g / 9.17 ounce Package size: 175 * 100 * 45 mm / 6.89 * 3.94 * 1.77 in Package weight: 295 g / 10.41 ounce Notes: 1.What is MPPT? Automatic load tracking aggregation. 2.Why Only works with the battery connected turn on the solar panel charges the battery charge does not work ? Why is it less than 100A? We are a current-focus MPPT with two constantan wires designed to detect current and maximum open-load when more 1A.This technology is our patent practice and has been recognized by the state with a special patent certificate of invention.There is no such technology on the market. Compared with other MPPT MPPT-inductive buck-boost type the same solar charging condition our current-focusing MPPT current tracking efficiency is higher because of the power loss caused by the booster and the step by step down. In fact the effectiveness of very low light charging is very low because the input power is very small. And our MPPT can also increase the load under relatively low illumination. Our MPPT is straight-through type. When the current is greater than 1A it will not be tested. The chain will be charged directly. Only when it is charged to 95% of the battery will it slow down and protect the battery. Package list: 1 * Solar charge controller
