20a 12v/24v mppt solar charge controller with lcd display for vehicles, boats, lighting and off-grid solar systems

Key features:

• Full safety protection: The unit features a full range of electronic safety functions including protection against over-charging, deep discharge, overload, reverse current at night, solar panel over voltage, short circuit and reverse polarity protection (of the solar panel and battery).
• Wide solar input range: The controller is suitable for solar panels with an open circuit voltage of up to 100V and with maximum power up to 310W (when charging a 12V battery or battery bank) / up to 620W (when charging a 24V battery or battery bank).
• Advanced battery compatibility: Suitable for use with a wide range of battery types, including: sealed, gel, flooded and lithium batteries. Advanced configuration of battery charging voltages is also possible.
• Terminals for a programmable load: Optional 12V appliances may be connected directly to the load terminals of the solar charge controller. The controller features a wide choice of 18 different load management programs. For example, the load can be programmed to operate only during the daytime / nighttime, thanks to the intelligent day/night sensor. Alternatively, more specific timers can be set to switch the load on for a certain number of hours.
• Backlit LCD screen: Displays vital system information including: power, voltage and current (for the solar panel and battery), a resettable energy counter (for the solar panel and load), battery temperature, load parameters, low battery indication, etc.
• Battery temperature sensor: Monitors and protects the battery from overheating. Temperature values are shown on the LCD display.
