PWM Solar PV Charge Controller

Available in 10A, 20A, and 30A Models

This PWM (Pulse Width Modulation) Solar PV Charge Controller is a high-performance regulator designed specifically for marine, caravan, and off-grid photovoltaic systems. Equipped with an industrial-grade microcontroller and a clear LCD display, it intelligently manages the charging and discharging of lead-acid batteries to maximize their lifespan and ensure system safety.

RELIABILITY: Built with dual MOSFET reverse current protection and an intelligent 4-stage PWM charging algorithm to prevent overcharging and battery sulfuration.

Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part, manufactured to meet original equipment (OE) performance standards for off-grid PV power regulation.

How do I know which amperage (10A/20A/30A) I need?

Select the model based on your solar panel output. For example: A 100W panel (approx 5.5A) works best with the 10A model. For 200W+ systems, the 20A or 30A model is recommended to ensure safety margins.

Is this controller compatible with Lithium (LiFePO4) batteries?

This specific model is designed for lead-acid battery types (Sealed, Gel, Flooded). It is generally not recommended for Lithium batteries unless your battery includes an internal BMS that accepts PWM lead-acid charging curves.

Note: Always connect the battery first before the solar panel to allow the controller to detect the correct system voltage (12V or 24V).
