The Felicity 80 A charge controller is an MPPT (Maximum Power Point Tracking) type solar controller designed to efficiently regulate and optimize the power flowing from your solar panels into a battery bank.
Specifications
- Electrical & Charging Specs
- • Rated Charging Current: 80 A maximum — this is the highest current the controller can deliver to the batteries. 
- • Nominal System Voltage: Auto‑detects 12 V / 24 V / 48 V operation. 
- • Maximum Solar Input Voltage (Voc): ~145 V DC maximum solar array input voltage. 
- • Maximum Solar Input Power (approx.):
- • 12 V: up to 1100 W
- • 24 V: up to 2200 W
- • 48 V: up to 4400 W 
- • MPPT Efficiency: up to ~98 % — very efficient at converting panel power to battery charging current. 
- • Charging Algorithm: Three‑stage charging (Bulk → Absorption → Float) for optimized battery life and performance.
