Product Description：
Y&H 140A high-voltage solar controller uses Maximum Power Point Tracking (MPPT) technology
to achieve maximum energy collection efficiency by monitoring the voltage and current output of the solar panel in real time.
Up to 500V input, which means it can handle more solar panels connected in series.
It can reduce the overall line loss and connection complexity of the system and improve charging efficiency.
Handles larger-scale solar power generation systems, suitable for applications requiring high current input,
such as large homes, commercial buildings or small off-grid power stations

Features:
1. Maximum power point tracking (MPPT) technology
2. Photovoltaic input voltage range 60-500VDC
3. Intelligent battery charging design to optimize battery life
4. Fast charging, balanced charging and float charging stages to extend battery life
5. Overcharge, over-discharge, short circuit, and PV overvoltage protection ensure the stable operation of the system and the safety of the battery.
6.LCD display and user interface,
7. Use dual fans for heat dissipation
