High-efficiency 40 A MPPT solar charge controller (TR4215BN) from Photonic Universe, with remote LCD display and 5 m cable, for 12 V or 24 V battery systems and solar inputs up to 150 V DC.

• MPPT Technology: Advanced Maximum Power Point Tracking (MPPT) to maximise array output and efficiency; compatible with 12 V and 24 V systems and solar input up to 150 V.
• Solar input / power rating: Supports PV arrays up to 520 W for 12 V systems or 1,040 W for 24 V systems; 40 A charging output.
• Full system protection: Comprehensive electronic protection including reverse-current stop at night, over-charge and deep-discharge cut-off, solar over-voltage, overload, short circuit and reverse-polarity protection plus self-diagnostic fault-targeting.
• Remote meter / display: Supplied remote LCD meter with 5 m (16.4 ft) RJ45 cable. Displays voltage, current (solar and load), state of charge, accumulated charge/discharge energy and min/max voltages. Remote meter self-consumption 15–65 mA (depending on backlight); remote meter size without frame 10 x 10 x 3 cm, with frame 12 x 12 x 5 cm; remote meter weight 230 g. Remote meter operating temperature: specified in the TR4215BN user manual.
• Personalised charging: Use factory defaults or configure custom settings. You will be able to: amend battery type and capacity; select charging volts for different charging stages; specify the duration of each charging stage; create a user-defined battery type with custom charging parameters.
• Battery compatibility & additional features: Works with sealed, gel, flooded or user-defined lead‑acid batteries; suitable for DC loads and common applications such as pumps.
• Controller specifications & protections: High-efficiency MPPT design, negative common ground, current limiting function, RS485/RJ45 communication port and multiple mounting holes for easy installation. Controller dimensions: specified in the TR4215BN user manual. Controller self-consumption <60 mA (12 V), <30 mA (24 V); working temperature -35 °C to +55 °C (-31 °F to +131 °F); enclosure IP30; weight approx. 2.9 kg (6.4 lb).
• Communication cable: RJ45 (8‑pin) 5 m included; wall‑mounting frame with mounting holes included.

Compatibility: Designed for 12 V and 24 V off‑grid battery systems; user manual for TR4215BN and supporting documents are available to download. For marine or mobile installations, follow applicable regulations and consider professional installation.
