High 20A MPPT Solar Charge Controller – 12/24V up to 150V | 4Boats

High-efficiency 20 A MPPT solar charge controller for 12 V or 24 V battery systems; supports high-voltage solar input up to 150 V and increased array power.

• MPPT Technology: Advanced Maximum Power Point Tracking to maintain peak power extraction; high efficiency >95%; accepts solar input up to 150 V and max array power 260W (12 V) / 520W (24 V).
• Full system protection: Comprehensive electronic protection including reverse current prevention at night (battery→panel), over‑charge and deep‑discharge cutoff, panel over‑voltage, overload, short circuit and reverse polarity; self‑diagnostic fault targeting and optional audible alarm to warn of system failures.
• Automatic battery recognition: Automatically recognises 12/24 V battery systems (always connect the battery to the controller before the solar panel).
• User interface and status: LED indicators show charging status and battery condition; compatible with remote meter MT50 (LCD) for monitoring and programming.
• Communication and ports: RS485/RJ45 communication port; negative common ground for simplified system wiring.
• Current limiting and expandability: 20 A current limiting protects the controller and allows future expansion of the PV array.
• Construction and installation: Die‑cast aluminium design for excellent heat dissipation; multiple mounting holes for ease of installation; Size: 21.6 x 14.2 x — cm (8.5 x 5.6 x — in); Weight: 1.5 kg (3.3 lb).
• Electrical & environmental specs: Self‑consumption <60 mA (12 V), <30 mA (24 V); working temperature −35°C to +55°C (−31°F to +131°F); grounding: negative common ground.
• Documentation: Supplied with user manual for TR2215BN; includes advanced protection features and communication options for remote monitoring.

Refer to the user manual for installation, wiring diagrams and compatibility notes; ensure battery is connected before solar panels and use correct fusing as advised.
