MPPT 100A Solar Charge Controller, Solar Panel Charge Controller, 12/24V Solar Panel Charge Controller

Features:
This product provides short-circuit protection, open-circuit protection, reverse polarity protection, and overload protection.
Auto-focusing MPPT tracking charge, high charging efficiency, non-stop detection during charging, and bidirectional focusing tracking.
The MPPT solar controller can detect the solar panel's voltage and current in real time and continuously track the maximum power, ensuring the system always charges the battery at maximum capacity.
The MPPT tracking efficiency is 99%, and the overall system power generation efficiency is up to 97%. In addition, the system features 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; turn on the solar panel to charge the battery, but the charging does not work"? Why is it less than 100A?
We are a current-focusing MPPT with two constant current wires designed to detect the maximum open current and load when it exceeds 1A. This technology is our patented practice and has been recognized by the state, with a special invention patent certificate. There is no other technology of this type on the market.
Compared to other inductive buck-boost MPPTs, under the same solar charging conditions, our current-focusing MPPT current tracking efficiency is higher due to the power loss caused by the booster and step-down. In fact, charging efficiency in very low light is very low because the input power is very low. Our MPPT can also increase charging under relatively low light conditions. Our MPPT is a direct type. When the current exceeds 1A, it will not be tested. The string will be charged directly. It will only slow down when the battery reaches 95% charge to protect the battery. Package List:
