Smart MPPT Solar Charge Controller — 30A
This compact MPPT solar charge controller automatically adjusts between 12V and 24V systems, maximizes solar harvest, and protects your battery with multiple safety features. It’s designed for reliable off-grid charging, easy monitoring, and efficient heat dissipation in a durable die-cast aluminum housing.
Benefits
- Extract more power from your panels so batteries charge faster and you get more usable energy each day.
- Protect batteries and appliances from damage with built-in safeguards, reducing maintenance and unexpected failures.
- Simplify system setup and monitoring with automatic voltage detection, an LCD + LED status display, and optional Bluetooth monitoring.
- Use a single controller for different battery types (sealed, gel, flooded, lithium), avoiding multiple purchases and installations.
- Durable metal housing and wide operating temperature range mean dependable performance in varied environments.
Features
- Auto-detects 12V or 24V DC systems.
- Compatible with Sealed, Gel, Flooded and Lithium deep-cycle batteries.
- MPPT technology with high tracking efficiency (greater than 99%) and conversion efficiency up to 98%.
- Electronic protections for reverse polarity, overcharge, over-discharge, overload, short circuit and reverse current.
- LCD screen plus multiple LED indicators for system status, adjustable parameters and error codes.
- Flexible load control and ability to charge over-discharged lithium batteries.
- Die-cast aluminum housing for efficient heat dissipation.
- RS232 communication port for use with the BT-1 Bluetooth module.
- Advanced MPPT algorithm that quickly finds the maximum power point on the I–V curve to improve energy yield.
