Product Details
High-Efficiency MPPT Charging with 80A Adjustable Output
This 60V MPPT Solar Charge Controller features advanced full-range I-V curve scanning technology to continuously track the maximum power point, delivering conversion efficiency of up to 97%. With an adjustable charging current of up to 80A, it supports different battery bank capacities and solar array configurations.
The actual charging output depends on available PV power and battery voltage. For example, an 80A output at 48V requires approximately 4kW of solar power, while a 24V battery system requires approximately half that PV power for the same charging current.
With a maximum PV open-circuit voltage of 230V, the controller supports longer series-connected PV strings, particularly for 48V battery systems. The PV startup threshold is only 3V above battery voltage, allowing charging to begin under low-light conditions, although actual charging current depends on available solar irradiance.
Flexible Battery Compatibility & Intelligent Charging
The controller features a touch-key LCD interface for convenient battery selection and charging parameter configuration.
Supported battery types and settings include:
- Lead-Acid Batteries: 12V–96V automatic recognition, with manual voltage selection for 60V/72V/84V/96V systems.
- Gel Batteries: Supports battery systems up to 96V.
- LiFePO4 Batteries: 3.2V per cell configuration.
- Li-ion Batteries: 3.7V per cell configuration, supporting 2–45 cells.
- USER Mode: Adjustable battery voltage parameters from 8V to 170V for customized charging configurations.
- Additional functions include DC load output without a battery connected when PV power is available, as well as battery charging voltage activation to help wake up a lithium battery BMS after protection shutdown.
RS485 Remote Monitoring & Multi-Unit Networking
Equipped with an 8-pin RS485 communication port, the controller can connect to a site server for remote operating status monitoring and parameter configuration.
Multiple controllers can share the same communication network, allowing centralized monitoring and alarm reporting to a remote office. This makes the unit suitable for distributed solar power systems, telecom stations and unattended remote installations.
Comprehensive Protection & Reliable Operation
Built-in protection functions help safeguard the solar charging system and connected equipment:
- Overcharge Protection
- Over-Discharge Protection
- Overload Protection
- Short-Circuit Protection
The controller is designed with a vented IP21 enclosure and natural convection cooling for reliable operation without additional cooling fans.
Wide Range of Solar Power Applications
Designed for various off-grid and backup power requirements, including:
- Telecom Base Stations
- Off-Grid Solar Power Systems
- Industrial Backup Power Systems
- Remote Monitoring Stations
- Unattended Solar Power Installations
OEM/ODM Manufacturing & Quality Assurance
