12V 24V PWM Solar Charge Controller with Big LCD Display USB Port Solar Panel Battery Regulator 10A 20A 30A
Feature:
Using industrial-grade main control chip.
Large screen LCD display, adjustable charge and discharge parameters.
Complete 3-stage PWM charging management.
Built-in over-current/short-circuit protection, open-circuit protection, and reverse connection protection, all of which are self-healing and do not damage the controller.
Dual MoS anti-backflow circuit, ultra-low heat.

Precaution:
1 This controller automatically adapts to 12V/24V lead-acid batteries. When installing for the first time, please make sure that the battery has enough voltage so that the controller can recognize the correct battery type.
2. Install the controller as close to the battery as possible to avoid the voltage drop caused by the excessive length of the wire and affect the normal voltage judgment.
3. This controller is only suitable for lead-acid batteries (including openings, seals, gels, etc.), please do not use other batteries (including lithium batteries, nickel-hydrogen batteries, etc.)
4. This controller can only use photovoltaic panels as the charging source, do not use DC or other power sources as the charging source.
5. This controller will heat up when it is running, please pay attention to install the controller on a flat, well-ventilated surface.
