Product Description:

Boost your solar performance. No frills, just function.
The EG4 MPPT100-48HV is a high-voltage, high-current solar charge controller built to get the most out of your solar panels—especially in larger or expanding systems. With a wide 500VDC input range, 100A charging capacity, and built-in breakers, this unit is designed for off-gridders, DIYers, and system builders who want dependable charging without overcomplicating things.

Why It Works:

High PV Input (500VDC Max) – Skip the combiner box. Connect two PV strings with branch connectors and start harvesting up to 5500W.
Fast Battery Charging (Up to 100A) – Capable of charging a 5.12kWh battery in about an hour—ideal for fast recovery after heavy use.
Built-in Protection – Comes with DC disconnect and internal battery breaker. No need to source extras.
Smart BMS Communication – Bridges the gap between EG4 batteries and non-EG4 inverters using RS485.
Efficient and Lightweight – 94% efficiency and <25W self-consumption keeps more power flowing where it counts.

Specs That Matter:

PV Array Voltage Range: 120–500VDC
Max Charging Current: 100A (adjustable; 80A default)
Battery Voltage: 48V nominal
Charge Voltage Range: 48–62VDC (default 56V)
MPPT Efficiency: 94%
Self-Consumption: <25W
Max PV Power: 5500W with 2 strings
Max String Current: 22A

What’s an MPPT Controller?

It’s the brain between your solar panels and your batteries. MPPT (Maximum Power Point Tracking) takes higher voltage from your solar array and intelligently converts it into usable voltage for charging—safely and efficiently.

Built for DIY Systems & Off-Grid Power Users

Whether you’re adding this to an existing setup or building a new one from scratch, the EG4 MPPT100-48HV gives you smarter charging, faster recovery, and fewer components to mess with.
