EpRec 30A PWM Solar Charge Controller — 12V/24V Auto, Li-ion/LiFePO4/Lead-Acid Compatible

Overview: versatile solar power management

The EpRec 30A Solar Charge Controller is crafted for compact to mid-size off-grid systems. It automatically detects 12V or 24V configurations and adapts to three battery chemistries, offering flexible pairing for a wide range of solar setups without sacrificing reliability. The controller emphasizes efficient regulation, helping you make the most of your daily sun exposure while preserving battery health.

Key capabilities

• Charge current up to 30A with four PWM stages (Boost, Absorb, Equalization, Float) to balance speed and battery longevity.
• Supports 12V/24V auto system voltage for streamlined installation.
• Max input power: up to 360W on 12V systems and 720W on 24V systems, enabling solid energy capture from modest solar arrays.
• Side-by-side USB output: dual 5V/2.5A ports to power essential devices directly from the controller.
• Backlit LCD displays real-time PV, battery, and load data for quick monitoring in any lighting condition.

Battery compatibility and intelligent control

• Battery types: lead-acid (12V/24V auto), lithium-ion (three strings of 11.1V), and lithium iron phosphate (four strings of 12.8V) for flexible energy storage choices.
• Intelligent control identifies daytime versus nighttime operation, adapting charging to conditions and protecting longevity.
• Automatic shut-off when the battery voltage falls below 8V to help prevent deep discharge (LCD becomes unavailable in this state).

Safety, protection, and reliability

• Eight protections safeguard both controller and system: dual MOSFET reverse current, overheat, under-voltage discharge, short-circuit, open-circuit, over-load, over-charging, and power-off memory.
• Robust temperature tolerance from -35°C to 60°C, designed for varied environments from workshops to cabins.
• Low self-consumption (<10 mA) so idle losses stay minimal when the system is resting.

How to connect your system

• Step 1: connect the battery to the regulator (plus and minus).
• Step 2: connect the photovoltaic module to the regulator (plus and minus).
• Step 3: connect the consumer/load to the regulator (plus and minus). Always follow the correct sequence to avoid damage.

Why choose EpRec

For travelers, tiny homes, boats, or off-grid cabins, this controller offers a practical balance of performance and protection. It does not promise guaranteed results, but it provides a solid basis for manageable solar charging with multiple battery options and clear real-time feedback.
