Photonic Universe 30 A MPPT solar charge controller for 12/24 V battery systems, supporting PV input (Voc) up to 150 V and maximum combined input 390 W for 12 V systems or 780 W for 24 V systems.

• MPPT Technology: This solar charge controller uses the most advanced Maximum Power Point Tracking (MPPT) to optimise power harvest, with MPPT tracking efficiency >95% (manufacturer specification).
• PV input: PV input (Voc) up to 150 V (use panel voltages higher than battery voltage for best results); maximum combined panel input 390 W (12 V) / 780 W (24 V).
• Full system protection: comprehensive electronic protection including reverse current prevention at night (prevents battery discharge back to the solar panel), automatic cut-off to prevent over‑charging and deep discharge, solar panel over‑voltage protection, overload, short circuit and reverse polarity; self‑diagnostic capability and optional audible alarm to alert the user of system failures.
• Automatic recognition: the controller automatically recognises 12 V / 24 V battery systems (note: always connect the battery to the controller before connecting the solar panel). LED indicators show charging status and battery condition.
• Current limiting & communications: 30 A current limiting function to allow adding more panels later; communication port RS485/RJ45 with negative common ground for monitoring and programming.
• Construction & cooling: die‑cast aluminium housing for excellent heat dissipation and multiple mounting holes for ease of installation.
• Electrical & environmental: self‑consumption <60 mA (12 V), <30 mA (24 V); working temperature -35 °C to +55 °C (-31 °F to +131 °F).
• Physical: Weight: 2.2 kg (4.85 lb). (Size/depth omitted until confirmed in official spec sheet.)
• Multiple connectivity options: compatible with remote meter MT50 (LCD) for monitoring and programming; the product includes a detailed user manual and is covered by manufacturer support.

Compatibility/care: suitable for off‑grid 12 V and 24 V battery systems; follow the supplied manual for wiring, commissioning and maintenance.
