ELUSH 100A MPPT Solar Charge Controller 12V–48V with 100V PV Input, LCD & Dual USB

The ELUSH Upgraded 100A MPPT Solar Charge Controller is a high-capacity, multi-voltage regulator that maximizes PV output while protecting and managing 12V–48V battery systems.

Built for medium to large off-grid solar arrays, this controller blends MPPT tracking, versatile control modes, and a readable LCD to monitor and tune charging for lead-acid and lithium batteries. It accepts PV inputs up to 100V, offers dual USB ports for small-device charging, and adds practical protections and timing features to simplify system management.

How does this controller increase solar harvest and system efficiency?

The ELUSH controller uses an advanced MPPT algorithm that continually adjusts to the solar array’s maximum power point, improving conversion of panel output into stored battery energy. Tracking efficiency is rated at no less than 99.5%, which helps capture more available wattage in variable light conditions.

• Advanced MPPT algorithm for fast, accurate power tracking
• Supports up to 100A continuous charging current
• Accepts 12V/24V/36V/48V battery systems automatically
• Displays real-time PV voltage for performance monitoring

What protection and monitoring features keep batteries safe?

This regulator integrates multiple safeguards and a dynamic LCD to display system parameters, helping prevent damage and diagnose issues quickly. Protections include over-voltage, over-current, reverse connection, overcharge, deep discharge, and thermal protection.

• Comprehensive voltage and current protections to prevent battery stress
• Overheat detection with safe-response behavior
• Real-time readout of battery voltage, charging/discharging current, and temperature
• Factory reset option for restoring default settings after troubleshooting

Which control modes and timing options are available for system automation?

The controller offers seven operating modes and now supports precise time control so loads and lighting can be scheduled or triggered by light sensors. The screen can remain illuminated for constant monitoring without entering hibernation.

• Charging, light control, light + time delay, universal, manual, and timing control modes
• Accurate on/off scheduling for lights or devices using clock functionality
• Continuous-bright LCD option for always-visible status
• Dual USB 5V outputs for phone or accessory charging

Which battery chemistries and installation tips should I know?

The ELUSH controller supports common battery types—sealed, GEL, flooded lead-acid, and LiFePO4—so you can match charging profiles to your battery chemistry. For proper startup and safe operation, always connect the battery first, confirm it has charge, then connect the solar array.

• Selectable charging profiles for Seal, GEL, Flooded, and LiFePO4 batteries
• Recommended connection sequence: battery first, then PV array
• Built-in display for verifying voltage and troubleshooting wiring issues
• 1-year warranty plus lifetime technical support from ELUSH

Who is this for? The ELUSH 100A MPPT controller is designed for homeowners, RV or boat owners, small commercial systems, and experienced DIY solar installers who need a high-current, versatile regulator for 12V–48V battery banks. It suits systems that demand improved solar harvest, configurable automation, and clear on-device monitoring without complex external monitoring hardware.
