MPPT & PWM Solar Charge Controllers

Maximize your solar efficiency and protect your power system with advanced solar charge controllers from GRN Solar Supply. Designed for precision energy management, our MPPT (Maximum Power Point Tracking) and PWM (Pulse Width Modulation) controllers regulate voltage and current from your solar panels to your batteries—ensuring safe, consistent charging and extending the lifespan of your entire system.

Efficiency Starts with MPPT Technology

For serious performance, MPPT charge controllers outperform standard PWM models by dynamically tracking solar array voltage to capture the highest possible power output—even in variable sunlight or partial shading. Whether you’re running an off-grid cabin or a hybrid home system, MPPT controllers deliver up to 30% higher efficiency, faster charge times, and smarter energy conversion.

Built for EG4 and Modern Solar Systems

Our controllers integrate seamlessly with EG4 batteries and hybrid inverters, supporting 12V, 24V, and 48V systems with automatic voltage recognition. Each unit features real-time LCD or app-based monitoring, allowing users to view system data, charge status, and battery health from anywhere. Engineered for reliability, these controllers include overcharge, reverse polarity, and short-circuit protection for total peace of mind.

Key Benefits

  • MPPT & PWM options for any system size
  • Supports LiFePO₄, AGM, Gel, and flooded batteries
  • Boosts charging efficiency by up to 30%
  • Temperature-compensated charging for long battery life
  • Compact, wall-mountable designs for easy installation

Off-Grid or Hybrid — Always Optimized

Whether you’re managing a single battery bank or a full hybrid energy setup, a high-quality solar charge controller is the heart of any stable power system. GRN Solar Supply’s curated selection ensures every watt you generate is efficiently stored and safely managed—day after day, year after year.

What does a solar charge controller do?

It regulates voltage and current from panels to batteries, preventing overcharging and extending battery life.
What’s the difference between MPPT and PWM controllers?

MPPT controllers are more efficient and ideal for larger systems, while PWM are simpler and cheaper for small setups.
Can one controller handle multiple panels?

Yes, if its input voltage and current ratings support your panel array.
How do I size my solar charge controller?

Multiply your total panel wattage by voltage, then choose a controller rated 20–25% above that current.
Do controllers need Wi-Fi or monitoring?

Optional — many MPPT models include Bluetooth or Wi-Fi for performance tracking.
