Felicity 24 V charge controller is an MPPT (Maximum Power Point Tracking) solar charge controller optimized to manage the power from a solar panel array and charge a 24 V battery bank efficiently
Specifications
- • System Voltage: 24 V DC (auto-detected — also supports 12 V and 48 V). 
- • Maximum Charging Current: Depends on model (e.g., 30 A, 45 A, 60 A, 80 A, etc., your specific unit determines this). 
- • MPPT Technology: Maximum Power Point Tracking for efficient solar harvesting (boosts energy capture compared to PWM). 
- • Maximum Solar Input Voltage:
- • ~95 V DC (e.g., 30A/45A models) 
- • Higher on large models (~145–195 V DC for higher amps) 
- • **PV Start-Up Voltage: Typically ~15 V DC (some models). 
- • MPPT Efficiency: ~98 % (high conversion efficiency). 
- • Charging Algorithm: 3-stage charge control — Bulk → Absorption → Float for better battery performance/longevity.

- 🔋 Battery & Charging Support
- • Battery Types Supported:
- ✔ Lead-acid (flooded)
- ✔ AGM
- ✔ Gel
- (Lithium support may require manual voltage setting on some models) 
- • Automatic Battery Voltage Detection: Automatically senses system voltage (12 V/24 V/48 V). 
- • Temperature Compensation: Some models include sensor support for better charging based on battery temp.

- 📊 Input & Output Power Ratings (Typical by Model)
- Example: 30 A Controller (SCCM3024-II)
- • Max PV Input Volt: ~95 V DC 
- • Max Solar Power: ~830 W @ 24 V 
- Example: 45 A Controller (SCCM4524-II)
- • Max PV Input Volt: ~95 V DC 
- • Max Solar Power: ~1250 W @ 24 V 
- (Larger/other amp ratings follow similar patterns with higher input power limits, e.g., 60 A ≈ 1650 W @ 24 V, 80 A ≈ 2200 W @ 24 V, etc.)
