Photonic Universe 20A 12/24V PWM Solar Controller, LCD+USB | 4Boats

Photonic Universe 20 A 12 V/24 V PWM solar charge controller with LCD display, selectable battery programs (Sealed/AGM, GEL, Flooded) and dual 5 V USB outputs (combined 2.4 A) for reliable battery management and device charging in RVs, boats and off-grid systems.

• Full system protection: electronic safety functions including reverse current blocking, automatic cut-off for over-charge, deep-discharge protection, overheating, overload, short-circuit and reverse polarity.
• Advanced programming and monitoring: LCD display with multilevel menu operation and two multifunction buttons; displays voltage, current, battery state of charge and battery temperature plus an energy statistics counter for daily and monthly accumulated charge values.
• PWM charging technology (Pulse Width Modulation): improves charge acceptance and extends battery life; selectable charging programmes for different battery types (Sealed/AGM, GEL, Flooded).
• Rapid USB charging: dual 5 V USB outputs, combined 2.4 A for fast charging of mobile phones, tablets, MP3 players and other USB devices.
• Compatibility: suitable for solar panels with combined input power up to 320W (12 V) or 640W (24 V); automatic 12/24 V system detection.
• Controller specifications: fully automated operation; rated charge/discharge current 20 A; maximum solar panel input power 320W (12 V) / 640W (24 V).
• Temperature compensation and environment: built-in temperature sensor with compensation -3 mV/°C/2 V (at 25°C); working temperature -25°C to +55°C (-13°F to +131°F); self-consumption: max. 10 mA.
• Additional features: in addition to the inbuilt temperature sensor, the controller provides a pair of terminals for an external (remote) temperature sensor or remote battery voltage sense to optimise the charging process.
• Physical and installation: mounting holes for ease of installation; size 16 x 9.5 x 5 cm (6.3 x 3.7 x 2.0 in); weight 350 g (0.77 lb); covered by a 1 year manufacturer warranty.

Suitable for 12 V loads (lighting, fans) connected to the controller; follow manufacturer guidance for correct wiring and battery selection to optimise charging performance and longevity.
