Genasun 8A MPPT 24V Solar Controlller

8A MPPT 36V Voltage-Boost Solar Charge Controller (41.7V Lithium)
Waterproof | 99% Efficient | Built for Marine, RV, Military & Off-Grid Systems

If you’ve ever tried charging a higher-voltage battery bank with lower-voltage solar panels, you know most charge controllers simply can’t do it.

This advanced voltage-boost MPPT charge controller lets you safely and efficiently charge 36V or 41.7V lithium battery banks using lower-voltage solar panels — with up to 99% peak efficiency.

Charge Any Voltage From Almost Any Panel

The GVB-8-WP doesn’t just regulate voltage — it boosts it.

That means you can:

• Charge 36V or 41.7V lithium batteries from 12V, 24V or 48-cell solar panels
• Use lightweight, compact solar panels instead of bulky high-voltage arrays
• Design simpler, more flexible systems for mobile or off-grid power

True MPPT — Not Marketing MPPT

Most “MPPT” controllers on the market are actually pulse-width modulated with marketing labels.

Genasun uses true high-speed Maximum Power Point Tracking, which:

• Continuously finds the exact optimal voltage
• Adapts instantly to changing sunlight
• Extracts up to 30% more power than PWM or fake MPPT controllers

You get real performance in real-world conditions — including cloudy skies and partial shade.

 Fully Waterproof. Fully Protected.

The GVB-8-WP is not just weather-resistant — it is fully potted in a proprietary compound that:

• Blocks water, salt, vibration & corrosion
• Protects sensitive electronics from shock & heat
• Allows installation in engine bays, marine lockers, and exposed environments

This is why Genasun controllers are used in:

• Military vehicles
• Ocean-going boats
• Mobile solar systems
• Harsh outdoor installations
