PWM Solar Charge Controller (Base Model) | Small home systems, RVs, cabins | - PWM charge mode (CE certified) - Max PV Voltage: 12V/24V - Max Power: 300W (supports 3 solar panels) - USB 5V/2.1A output | - Cost-effective - Reliable for moderate loads - Easy installation | - Lower efficiency in low-light conditions - Limited to 300W systems |
MPPT Solar Charge Controller (Industry Standard) | Large residential systems, off-grid cabins | - MPPT charge mode (IEC 61215 certified) - Max PV Voltage: 100V - Max Power: 600W+ - Efficiency: 95% (vs PWM’s 80%) | - Higher efficiency in low-light - Handles high voltages - Scalable | - 30%+ cost premium - Requires complex setup - No USB output |
High-Power PWM Controller (Our Advanced Model) | Commercial setups, large home systems | - PWM charge mode (CE) - Max PV Voltage: 50V - Max Power: 1500W (▲ +1200W from Base) - USB-C 10W output | - Handles 1500W arrays - Same reliability as Base - USB-C convenience | - Less efficient than MPPT - Bulkier design - 20% higher cost than Base |
Basic Voltage PWM Controller (Industry) | Tiny homes, small cabins | - PWM charge mode - Max Voltage: 12V only - Max Power: 100W - No USB port | - Inexpensive (50% cheaper than Base) - Simple wiring | - Limited to 12V systems - No scalability - No USB charging |
Entry-Level PWM Controller (Industry) | DIY projects, small solar kits | - PWM charge mode - Max Power: 200W - No display - 6-month warranty | - Budget-friendly (30% cheaper than Base) - Lightweight | - No real-time monitoring - Shorter warranty - Minimal protections |
Advanced PWM Controller with USB (Our Advanced) | RVs, mobile setups needing USB charging | - PWM charge mode (CE) - Max Power: 1500W (▲ from Base’s 300W) - 5 Protections (overcharge, over-discharge, etc.) - USB-C 10W | - Versatile with USB-C - Robust protections - Dual-voltage (12V/24V) | - Higher cost than Base - Still less efficient than MPPT - Requires space for ports |
