Product Description

Intelligent 5 Stage Charging 20A Marine Solar Charge Controller With BMS Wake Up

The MT515 Digital 20 amp Solar Charge Controller is a reliable and efficient PWM controller for 12V or 24V solar power systems. Equipped with MCU control PWM technology, it ensures high-efficiency operation while protecting your battery from overcharging and extending battery life.

The 5-stage charging process (Soft Start, Bulk, Absorption, Equalization, Float) optimizes battery charging, ensuring full capacity while protecting against overcharging and other common issues. The BMS wake-up feature allows charging even when batteries are in a low-power state.

Built with durability in mind, the controller features an IP67 rating for protection against dust and water. Its compact dimensions (102×130×27mm) make it easy to install in various environments, including outdoor and industrial settings.
