Photonic Universe 20 A 12 V/24 V MPPT solar charge controller with backlit LCD, designed and manufactured in Italy to high European quality standards for vehicles, boats, vans, RVs, lighting and off‑grid systems.

• Advanced MPPT technology to maximise system efficiency with fully automated 12 V/24 V operation; supports wires up to 10 mm².
• Full safety protection: the unit features a full range of electronic safety functions including over‑charging, deep discharge, overload, reverse current at night, solar panel over‑voltage, short circuit and reverse polarity protection (panel and battery).
• Wide solar input range: suitable for solar panels with an open circuit voltage up to 100 V and maximum power up to 310 W (when charging a 12 V battery) / 620 W (when charging a 24 V battery).
• Advanced battery compatibility: suitable for sealed, gel, flooded and lithium batteries with configurable charging voltages.
• Terminals for a programmable 12 V load: optional 12 V appliances may be connected directly to the load terminals; includes 18 load management programmes, day/night sensing and timer options.
• Backlit LCD screen: displays vital system information including power, voltage and current for the solar panel and battery.
• Battery temperature sensor: monitors and protects the battery from overheating; temperature values are shown on the display.
• Specifications and installation: self‑consumption 12.7 mA; working temperature -10 °C to +50 °C (14 °F to 122 °F); unit dimensions 154 x 130 x 53 mm (6.06 x 5.12 x 2.Ø 9 in) including mounting edges; mounting area 134 x 122 mm (5.28 x 4.80 in); weight 515 g (1.14 lb); mounting holes for ease of installation.

Suitable for a wide range of mobile and off‑grid applications; confirm panel open‑circuit voltage and battery type before installation and use the supplied battery temperature sensor for optimal charging performance. Also functions as a reliable PV charge controller / solar regulator for vehicle and marine systems.
