It converts higher-voltage solar input into the lower, steady voltage needed to safely charge a 48V battery bank, making it a strong option for expanding or improving a new or existing solar system. Key Benefits Maximizes Solar Harvesting: Uses MPPT technology to pull the most available power from your solar panels for more efficient battery charging. High-Voltage PV Input: Supports up to 500VDC open-circuit voltage, helping reduce the need for combiner boxes in certain system designs. Fast Battery Charging: Delivers up to 100A of charging current, with adjustable settings from 0A–100A. Designed for 48V Battery Systems: Built for 48V nominal battery banks with a 48–62VDC charging range. Built-In Protection: Includes PV array DC disconnect and battery breakers for added system safety. EG4 Battery Communication: Communicates with EG4 batteries through the RS485 BMS port when used with non-EG4 compatible inverters. Use Cases The EG4 MPPT100-48HV is ideal for adding more solar charging capability to off-grid, backup power, cabin, RV, and battery-based solar systems. It can also be used to expand an existing system where additional PV input is needed to support faster charging and better energy production.
