12V/24V MPPT Solar Controller Battery Charger, 30A

As a top-of-the-line and most advanced solar charge controller, it charges the battery with maximum power. The MPPT tracking efficiency is 99%, and the overall system power generation efficiency reaches 97%. Features: This product offers short-circuit protection, open-circuit protection, reverse connection protection, and overload protection. MPPT automatically charges and tracks the current, with high charging efficiency, continuous detection during charging, and bidirectional tracking. The MPPT solar charge controller can detect the voltage and current of the solar panels in real time and continuously track the maximum power output, ensuring the system always charges the battery at maximum capacity. The MPPT tracking efficiency is 99%, and the overall system power generation efficiency is 97%. Furthermore, the system has excellent battery management functions, including MPPT charging, constant voltage charging, and constant voltage floating charging.

Automatic Load Tracking Aggregation. 2. Why does it say "it only works when connected to the battery; charging the solar panel from the battery does not work"? Why is it less than 100A? Our current MPPT development features two constant wires and is designed for open-circuit detection under no-load conditions and with a maximum current of 1A. Compared to other types of Buck-Boost or Induction MPPTs, for the same solar charging state, our current-focusing MPPT is more efficient due to the power loss achieved through boosting and bucking. In fact, charging efficiency in ultra-low light is very low because the input power is very low. Our MPPT can also increase charging in relatively low light conditions. Our MPPT is delivered directly to the power supply. No 1A testing is performed. The current will be charged directly. It will only slow down when the battery is 95% charged to protect the battery.
