The Felicity 100 A solar charge controller is an advanced Maximum Power Point Tracking (MPPT) controller designed to efficiently regulate and optimize the power coming from your solar panels into your battery bank.
Specifications
- Rated Charging Current: up to 100 A — supports large battery banks. 
- • Compatible System Voltages: 12 V / 24 V / 48 V (auto‑detect) — automatically selects the correct system voltage. 
- • Maximum PV Input Voltage: ~145 – 195 V DC depending on model/variant. 
- • Max PV Input Power: ~1,375 W @ 12 V, 2,750 W @ 24 V, and 5,500 W @ 48 V (typical power handling). 
- • Charging Stages: 3‑stage charging — Bulk, Absorption, Float — for safe, full battery charging. 
- • MPPT Efficiency: Up to ≈ 98 %, meaning it harvests nearly all usable power from the solar array. 
- • Battery Support: Works with lead‑acid, AGM, Gel, and lithium batteries (lithium may require manual setting). 
- • Display/Monitoring: Often has an LCD screen for viewing voltages, currents, and status; some versions support remote monitoring via communication ports (e.g., MODBUS).

- 🧠 Core Features & Benefits
- ✅ MPPT Technology:
- Maximizes power extraction from solar panels by continuously tracking the optimum power point as light conditions change — much more efficient than PWM controllers. 
- ✅ Automatic Voltage Detection:
- Auto‑detects whether your system is 12 V, 24 V, or 48 V and configures itself accordingly. 
- ✅ Three‑Stage Charging:
- The Bulk → Absorption → Float stages help protect batteries and prolong their life by applying the right charging strategy at each phase. 
- ✅ Wide Battery Compatibility:
- Supports multiple battery types — sealed lead‑acid, gel, AGM, and lithium. 
- ✅ High Efficiency:
- Up to ~98 % MPPT conversion efficiency improves energy harvest from your solar array.
