Solar Charge Controller Epee MPPT TRACER 5420AN 50A

The Solar Charge Controller Epee MPPT TRACER 5420AN 50A is a maximum power point tracking (MPPT) regulator designed to manage charging of batteries from photovoltaic (PV) arrays. It continuously optimizes PV output to achieve higher energy harvest compared with simple PWM regulators and provides regulated charging and battery protection functions for off-grid solar systems, recreational vehicles and small commercial installations.

Advantages

This MPPT charge controller delivers up to 50 A of charging current while using MPPT algorithms to track the PV array’s maximum power point, improving conversion efficiency under varying irradiance and temperature conditions. Built-in battery protection prevents overcharging and deep discharge, while regulated charging stages support battery health. The unit is compact and designed for straightforward installation and integration into typical 12 V or 24 V battery systems.

Suitable for

• Off-grid solar home systems with lead‑acid or compatible battery banks
• Recreational vehicles, boats and mobile power setups
• Small commercial or remote monitoring installations
• Systems needing improved PV energy harvest and battery maintenance

Key specifications

• Maximum charging current: 50 A
• MPPT tracking for improved photovoltaic power conversion
• Compatible with 12 V and 24 V battery systems (automatic or manual selection depending on wiring)
• Multi-stage charging to support battery longevity
• Protections: overcharge protection, reverse polarity protection, short-circuit protection
• Display or status indicators for charge state and fault reporting

How to use

Connect the PV array, battery and load according to the manufacturer’s wiring diagram, ensuring correct polarity and proper cable sizing for the expected current. Select or confirm the system voltage (12 V or 24 V) before operation and power up the controller. Monitor status indicators to verify charging operation and check that the unit is tracking the PV array’s maximum power point. Configure any available battery type or charge profile settings to match the battery chemistry in use. Periodically inspect connections and the controller for proper ventilation and absence of debris.

Recommendations

Use appropriately rated PV array and battery cables, fuse or circuit breakers on the battery positive line, and follow battery manufacturer guidelines for temperature compensation and charge parameters. Avoid mounting the controller in direct sunlight or enclosed unventilated spaces to maintain thermal performance and longevity.
