Features:
1. Using industrial-grade main control chip;
2. Large screen LCD display, adjustable charge and discharge parameters;
3. Complete 3-stage PWM charging management;
4. Built-in over-current / short-circuit protection, open circuit protection, reverse connection protection, all are self-recovery, without damaging the controller;
5. Double MOS anti-backflow circuit, ultra-low heat generation.

Recommendations for safe use:
1. The controller is a 12V / 24V lead-acid battery-automatic adaptation. When installing for the first time, please ensure that the battery has sufficient voltage so that the controller can recognize the correct battery type.
2. Install the controller as close to the battery as possible to avoid voltage drop caused by excessively long wires and affect normal voltage judgment.
3. Only applicable to various lead-acid batteries (including openings, seals, gels, etc.), do not use them for other batteries (including lithium batteries, nickel-metal hydride batteries, etc.)
4. Only use the photovoltaic panel as the charging source, do not use DC or other power sources as the charging source.
5. The controller will generate heat during operation, please pay attention to install the controller on a flat, well-ventilated surface.
