Supports remote monitoring, setup and control with Bluetooth & WiFi dongle.
Original SRNE Shiner 2420 20A is an advanced MPPT solar charge controller designed for 12V and 24V battery systems. Featuring Maximum Power Point Tracking (MPPT) technology, these controllers enhance solar energy utilization by 20% compared to traditional PWM controllers. They support remote monitoring, setup, and control through optional Bluetooth and WiFi dongles, allowing convenient management and configuration from smartphones or computers.
Compatible with multiple battery types including lithium, lead-acid, gel, sealed, vented, and user-defined batteries, the Shiner controllers are ideal for solar home systems, off-grid solar setups, and industrial solar applications. Key protections include over-temperature protection, short circuit protection, reverse polarity protection, battery open circuit protection, and TVS lightning protection, ensuring safety and long-term reliability.
