ECOFLOW 4mm² 3M MC4 to XT60i Solar Charge Extension Cable

The ECOFLOW 4mm² 3M MC4 to XT60i Solar Charge Extension Cable is a high-amperage-ampere charge controller for solar systems, available in MPPT (Maximum Power Point Tracking) or PWM (Pulse Width Modulation) technologies. The controller regulates power from solar panels to batteries, preventing overcharge and extending battery lifespan significantly.

MPPT controllers achieve 95-98% efficiency by continuously tracking the optimal voltage-current combination, while PWM controllers offer simpler operation at 70-80% efficiency. The multi-voltage input accepts multiple-volt systems and automatically adjusts charging profiles based on battery voltage and temperature.

An integrated LCD display shows real-time parameters: solar voltage/current, battery voltage/current, daily energy generated, and system temperature. Thermal protection and temperature sensors ensure safe operation in extreme conditions. Multiple charging stages (bulk, absorption, float) optimize battery charging and lifespan.

Installation involves connecting solar panels to the controller input and the battery to the output. Temperature sensor probe placement near the battery improves charging accuracy. Proper breaker and fuse protection on both input and output is essential for safety. Compatible with sealed, flooded, lithium, and other battery chemistries.
