MPPT 30A Solar Charge Controller, 12V 24V Automatic Identification, 30A Solar Panel Battery Regulator with LCD Temperature Probe and 2 USB Ports

Features:
This product provides protection against short circuits, open circuits, reverse polarity, and overloads.
Auto-focusing MPPT charging, high charging efficiency, continuous detection during charging, and bidirectional tracking.
The MPPT solar controller detects the solar panel's voltage and current in real time and continuously monitors them, allowing the system to continuously charge the battery.
The MPPT tracking efficiency is 99%, and the overall system power generation efficiency reaches 97%.
Furthermore, the system offers excellent battery management, including MPPT charging, constant voltage average charging, and constant voltage float charging. Specifications:

1.What is MPPT?
Automatic load tracking aggregation.
2.Why does it say, "Only works with the battery connected; turning on the solar panel charges the battery, but the charging doesn't work"?Why is it less than 100 A?
We offer a current-focusing MPPT with two Constantan wires, designed to detect the maximum open current and load from 1 A.This state-patented technology has been granted a special invention certificate.There is no other technology of this type on the market.
Compared to other inductive step-up/step-up MPPTs operating under the same solar charging conditions, our current-focusing MPPT performs better in terms of current tracking, due to the power loss caused by the amplifier and the gradual reduction of the current.
Indeed, charging efficiency in very low light conditions is very low due to the low input power.Furthermore, our MPPT can also increase the charge under relatively low light conditions.Our MPPT is a direct type.It is not tested when the current exceeds 1 A.The string is charged directly.It only slows down when the battery reaches 95% charge to protect the battery.
