Compact 30A PWM Solar Charge Controller — Smart Battery Management
Overview
A compact PWM solar charge controller with MOSFET switching that manages charging for a wide range of batteries. It offers smart charging control, clear LED and digital indicators, multi-layer protection, and a slim, corrosion-resistant design for reliable, low-power operation in small solar systems.
Benefits
- Protects and extends battery life by applying the right charge profile and preventing damaging conditions.
- Reduces energy waste and keeps systems running longer with high efficiency and low standby draw.
- Makes monitoring simple — LED indicators and a digital display show battery condition and charging status at a glance.
- Minimizes installation hassle with common positive grounding and corrosion-resistant terminals for durable connections.
- Fits into tight spaces thanks to an ultra-thin, compact form factor for easy wall mounting.
- Improves safety and uptime with automatic protections (over-voltage, short-circuit, reverse polarity, thermal) and no-spark connections.
Features
- PWM charging control using MOSFET switching for efficient regulation.
- Common positive grounding connection for simpler wiring in many systems.
- Selectable battery type and clear battery-condition indication.
- Smart charging control with managed charging time and automatic adjustments.
- LED indicators and a digital display for charging parameters and battery settings.
- Automatic activation of Lithium batteries that are protected by a BMS.
- Thermal protection and safeguards against over-voltage, short circuit, and reverse polarity.
- No-spark design and corrosion-resistant terminals and connectors for safer, longer-lasting hookups.
- Conformal coating on the internal board to resist moisture.
- External battery temperature sensor (BTS) port for improved temperature-compensated charging (sensor optional).
- Compatible with most rechargeable lead-acid batteries (Flooded/WET, AGM, GEL, Calcium) and Lithium batteries.
- Designed to meet CE standards and comply with EMC and FCC regulations.
