Solar Controller, 80A — reliable charge management for 12V to 48V battery systems This solar controller delivers flexible and reliable charging for a wide range of battery types and system voltages. It combines automatic recognition, low standby loss, and robust construction to provide stable charging and everyday convenience. Key benefits Broad battery compatibility: Default battery type is sealed valveregulated leadacid. Also compatible with gel, liquid leadacid, lithium iron phosphate, and ternary lithium batteries. Parameter is supported for other battery types; refer to the manual to configure settings. Automatic operation: Intelligent recognition eliminates the need for manual voltage selection or frequent adjustments. The controller detects system voltage and manages charging automatically. Wide system adaptability: Works with 12V, 24V, 36V, and 48V battery systems, making it suitable for small to large offgrid installations. Efficient and low loss: Static loss is 20mA or less, and loop voltage drop is 0.3V or less, conserving battery energy during standby and operation. Practical outputs: Two USB outputs at 5V 2A each provide convenient charging for mobile devices or small accessories. Durable design: Engineering plastic housing and quality components ensure long service life under normal operating conditions. Easy installation and connections: Terminals accept 4AWG / 25mm2 cable for secure, current wiring.

Remote telecommunications or monitoring stations: Low standby loss and reliable charging extend battery service life and reduce maintenance frequency. Small commercial or agricultural systems: Support for multiple battery chemistries and current capacity suits lighting, pumps, and other DC loads. What this controller solves Removes manual setup hassles by detecting system voltage and managing charge parameters automatically. Fits diverse battery chemistries and voltages so the same controller can be used across multiple installations. Reduces parasitic drain and voltage loss, helping batteries retain charge longer between cycles. Provides convenient USB charging for everyday devices without needing separate adapters. Installation and setup notes Confirm battery chemistry and, if using a battery type other than the default, set the appropriate parameters as described in the user manual. Ensure the solar panel opencircuit voltage does not exceed 100V. Use appropriate cable sizes and secure terminal connections; terminals accept up to 4AWG / 25mm2. This controller is a practical choice for users who need flexible battery compatibility, automatic operation, and efficient, durable charge control in 12V to 48V solar systems.
