AS-P Solar Charge Controller auto-sensing voltage recognition
The AS-P Series Solar Charge Controller is a compact and intelligent PWM-based energy management solution designed for 12V/24V solar systems, offering reliable battery protection and efficient solar harvesting across residential, RV, and small off-grid applications. With auto-sensing voltage recognition, it seamlessly adapts to diverse setups, supporting up to 60A PV input (model-dependent) and a wide PV open-circuit voltage range (10–60A models).
Equipped with a 4-stage PWM charging algorithm (bulk, absorption, float, and temperature-compensated equalization), it optimizes battery health for Gel, AGM, Flooded, and Sealed lead-acid batteries, extending lifespan through precise voltage regulation.
Product Introduction
Key features include an LCD display for real-time monitoring of solar input, battery status, and load conditions, alongside a 5V/3A USB port for direct mobile device charging. Advanced protections such as low-voltage disconnect (10.7V/21.4V), automatic reconnection (12.6V/25.2V), and temperature compensation (-4mV/℃/cell) ensure system safety and stability in harsh environments (-20℃ to +60℃).
Its ultra-low no-load loss (≤20mA) and minimal loop voltage drop (≤170mV) maximize energy efficiency, while the lightweight, IP20-rated design (180–200mm compact dimensions) enables easy installation in space-constrained setups. Ideal for solar street lights, cabins, or marine systems, the AS-P series balances affordability, durability, and user-friendly operation for sustainable off-grid power management.
