Optimize Your Solar Harvest
A Solar Charge Controller is an essential component in any solar power system that utilizes batteries. It regulates the voltage and current coming from the solar panels to the battery, preventing overcharging and ensuring optimal battery life. Zenvo offers both PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking) controllers to suit various system sizes and efficiency needs.
Key Features (Common Across Zenvo Controllers)
- Intelligent Battery Charging Algorithms to extend battery life.
- Comprehensive Overcharge & Deep Discharge Protection.
- Interactive LCD Display for real-time system status.
- High Conversion Efficiency (Up to 98% for MPPT models).
- Automatic System Voltage Detection (12V/24V/48V).
Product Models & Technical Specifications
Cost-effective solutions for smaller solar systems. Reliable performance for standard applications. Our PWM controllers use advanced digital signal processing to control charging, acting as a highly intelligent switch between the solar array and the battery.
| Model | Current Rating | System Voltage |
|---|---|---|
| Z-PWM-10 | 10A | 12V / 24V Auto |
| Z-PWM-20 | 20A | 12V / 24V Auto |

Advanced controllers that extract the maximum possible power from PV modules, increasing system efficiency by up to 30%. Using sophisticated algorithms, MPPT controllers track the optimal working point of the solar panel to deliver maximum current to the battery.
| Model | Current Rating | Max PV Voltage | Efficiency |
|---|---|---|---|
| Z-MPPT-20 | 20A | 100V | 98% |
| Z-MPPT-40 | 40A | 150V | 98% |
| Z-MPPT-60 | 60A | 150V | 98% |
Notes & Recommendations
- Technology Choice: Use PWM for smaller 12V/24V systems where panel voltage closely matches battery voltage. Choose MPPT for larger systems or when using high-voltage grid-tie panels to charge battery banks.
- Protection: Ensure proper breaker sizing between the controller, panels, and batteries for maximum safety.
