Managing two separate battery banks—like a house bank and a dedicated engine start battery—is often overlooked in long-term setups. This 10A PWM controller solves that problem by efficiently charging two completely isolated battery banks simultaneously using Pulse Width Modulation technology.
This ensures your critical starting battery never gets drained while you’re stationary, maximizing reliability. It features high-efficiency charging and essential electronic safeguards against overcharging, short circuits, and accidental reverse connections. For anyone running an off-grid system where maintaining the health of two separate batteries is necessary, this dual-bank controller offers excellent value and peace of mind
