High 20A MPPT Controller 12/24V, 150V PV | 4Boats

High 20 A MPPT solar charge controller with remote LCD meter (5 m cable) for off-grid 12/24 V systems; accepts PV input up to 150 V.

• MPPT Technology: Maximum Power Point Tracking (MPPT) optimizes solar-panel output as sunlight and temperature vary, improving charging efficiency versus PWM. Wide PV input supports panel voltages up to 150 V and maximum combined PV power of 260 W (12 V) or 520 W (24 V).
• Full system protection: Comprehensive electronic protection including reverse-current stop at night, automatic overcharge cut-off and deep-discharge prevention, solar-panel over-voltage, overload, short-circuit and reverse-polarity protection, plus self-diagnostic fault-targeting.
• Remote meter / display: Supplied remote LCD meter with 5 m cable. Displays solar and load voltage and current, battery state of charge, accumulated charge/discharge energy and min/max voltages. Meter operating temperature -35°C to +55°C (-31°F to +131°F).
• Load output: Load output supports DC appliances such as lights and pumps (see manual for current limits and recommended loads).
• Personalized charging: Choose factory defaults or configure settings to amend battery type and capacity, select charge voltages for each charging stage, specify stage durations and create user-defined battery types with custom charging parameters.
• Battery compatibility & additional features: Compatible with sealed, gel, flooded or user-defined lead-acid batteries; current-limiting function; negative common ground.
• Communications & installation: RS485 / RJ45 (8-pin) interface for system communications. RJ45 communication cable (8-pin) 5 m included. Multiple mounting holes and a wall-mounting frame included for easy installation.
• Controller specifications: Self-consumption <60 mA (12 V) and <30 mA (24 V); working temperature -35°C to +55°C (-31°F to +131°F); enclosure IP30; weight 1,500 g (3.31 lb). Size: see product manual for exact external dimensions and mounting cutouts.
• Remote meter specifications: Self-consumption 15–65 mA (depending on backlight); communication cable RJ45 (8-pin) 5 m included; size without frame 10 x 10 x 3 cm (3.9 x 3.9 x 1.2 in); size with frame 12 x 12 x 5 cm (4.7 x 4.7 x 2.0 in); weight 230 g (0.51 lb); operating temperature -35°C to +55°C (-31°F to +131°F).
• Installation & documentation: Supplied with a detailed user manual explaining wiring, operation and safety precautions.

Always confirm battery chemistry and negative-common grounding before installation; refer to the user manual for wiring diagrams, load limits and safety guidance.
