IVT MPPT Solar Charge Controller 30 A, 12/24 V, LCD, RS485 18319

Solar systems often waste energy because traditional PWM controllers cannot fully utilise the power from modern solar panels. The IVT MPPT Solar Charge Controller 30 A solves this by using Maximum Power Point Tracking to extract the maximum available power from your PV array, even under changing light and temperature conditions. It supports both 12 V and 24 V battery systems with automatic detection and works with lead-acid (GEL, AGM, flooded) and lithium (LiFePO4) batteries.

Who is it for

This controller is for off-grid solar installations, motorhomes, boats, and remote cabins where efficient battery charging is essential. It suits users who need a reliable, high-performance charge controller with advanced monitoring and communication options.
