EcoSolLi 120A MPPT Solar Charge Controller — 12V–96V Auto‑Detect, 230V PV Input, LCD, 98% Efficiency

EcoSolLi 120A MPPT Solar Charge Controller is a high-capacity, multi-voltage regulator that maximizes solar harvest for 12V–96V battery systems and supports up to 230V PV input.

This professional-grade MPPT (Maximum Power Point Tracking) charger from EcoSolLi is built to squeeze the most energy from solar arrays while protecting batteries and electronics. It automatically adapts to system voltages from 12V through 96V, supports common battery chemistries such as LiFePO4 and lead-acid variants (GEL, AGM, SLD), and delivers advanced safety and diagnostics through an integrated LCD. With peak conversion efficiencies approaching 98% and tracking efficiency above 99%, it’s designed for large residential or commercial off-grid arrays where reliable, efficient charging matters.

How does this controller improve solar charging compared with basic regulators?

The EcoSolLi MPPT controller continuously finds the solar array’s optimum operating point so it converts more sunlight into battery charge than PWM units. That means faster recharge times and better energy yield on cloudy or variable conditions. Its internal electronics maintain conversion efficiency near the peak levels for long-term savings and performance.

• MPPT tracking efficiency ≥ 99% for precise power harvesting.
• Peak DC–DC conversion efficiency up to 98% to reduce losses.
• Supports very high PV input (max 230V) for larger arrays.

Which battery types and system voltages are compatible?

This unit auto-detects and handles a broad range of battery systems and voltages, removing guesswork during setup. It supports standard 12V, 24V, 36V, 48V, 60V, 72V, 84V and 96V systems and programmed charging profiles for lithium and various lead-acid chemistries. That versatility makes it suitable for mixed or scaled installations.

• Auto-recognition for 12–96V battery systems.
• Preconfigured profiles: LiFePO4, FLD, SLD, GEL, AGM.
• Selectable charging parameters for float, bulk and absorption stages.

What protections does the controller provide to keep the system safe?

Safety is built-in with multiple electronic protections and automatic fault checks to prevent damage from common installation or operational errors. The controller guards against overcurrent, overvoltage, overload, over-temperature and deep discharge events, and includes cold-temperature charging logic for battery health. These layers of protection improve system reliability and lower maintenance risk.

• PV overcurrent and battery overvoltage protection to prevent component stress.
• Load overload and battery discharge protection to safeguard connected devices.
• Over-temperature and low-temperature charging adjustments for battery longevity.

How will I monitor performance and configure settings?

An integrated LCD gives clear, real-time readouts and menu-driven configuration so you can check system voltage, charging current, and fault codes at a glance. The display simplifies commissioning and troubleshooting without requiring external tools. Advanced users can verify settings and performance data directly from the controller interface.

• LCD screen for instantaneous status and parameter access.
• Menu-based setup for system voltage and battery type selection.
• Onboard diagnostics and self-test routines for quick fault identification.

Who is this for: Installers, system integrators and homeowners who run medium-to-large off-grid or hybrid solar setups and need a high-efficiency MPPT controller that supports wide voltage ranges and multiple battery chemistries. It suits arrays that require high PV input voltage, robust protection features, and straightforward on-device monitoring for reliable day-to-day operation.
