20A Solar Charge Controller FS-ST20A

Automatically identify system voltage, 12/24V automatic identification. The positive poles of solar panels, batteries, and solar charge controllers are all connected together, and negative MOSFETs are used to control the circuit in series.

Using the optimized control chip, it truly realizes three-stage PWM charging, and the charging efficiency is 15% higher than that of products of the same level.

The shell is made of high-quality flame-retardant PC material, which is firm and durable. The back cover is made of aluminum alloy heat sink cover, which greatly improves the heat dissipation performance, and improves the conversion efficiency and service life of the product.

Easy to install and operate: Large LED display, can clearly display working status and data, 2 function power buttons, switch mode and parameter configuration.

Multi-purpose application: Load control mode can be selected, night street lamp timer function can be reset; discharge capacity control; ampere-hour discharge counter. Accurate temperature compensation, automatic correction of charge and discharge voltage, improve battery life.

Good heat dissipation performance: Double reverse current protection, low heat generation. All electronic components generate heat when they are in operation, and it is best to shield them to better dissipate heat and avoid direct sunlight or damp places.

Reliable protection: Reliable overvoltage protection, short circuit protection, overload protection, overcharge protection, over discharge protection, reverse connection protection, overheating temperature protection.
