20A MPPT Solar Charge Controller For Solar Panels Up To 260W

20A MPPT Solar Charge Controller For Solar Panels Up To 260W

MPPT Technology:

This solar charge controller uses the most advanced Maximum Power Point Tracking (MPPT) technology to track the maximum power voltage point of solar panels as it varies depending on sunlight exposure and temperature. This technology ensures the maximum efficiency of your solar system and significantly outperforms standard PWM solar controllers. Another benefit of MPPT technology is the wide solar input voltage range - this controller can work not only with standard off-grid 12/24V solar panels, but also with multiple panels with voltage up to 100V. The maximum combined input solar power allowed for this controller is 260W for a 12V battery system or 520W for a 24V system. In particular, this controller will significantly increase efficiency of a solar system where the solar panel voltage is much higher than the battery voltage (e.g. charging a 12V battery with a 36V solar panel).

Full system protection:

This charge controller features a comprehensive set of electronic protection functions to ensure the maximum possible efficiency of your solar system. These include: reverse current prevention at night (from the battery back to the solar panel), automatic cut off to prevent over-charging and deep discharge, solar panel over voltage, over load, short circuit and reverse polarity protection.  The controller also has self-diagnostic capability and highlights any system errors using advanced fault-targeting technology. 

Lithium Battery charging:

This solar charge controller is compatible with lithium batteries when a lithium battery charging program is selected using PC software or mobile app (see below for more details).

Advanced system monitoring:

• The controller automatically recognises 12/24V battery systems (note a battery should always be connected to the controller first before connecting a solar panel)
• Built-in LCD screen shows real-time charging parameters such as voltage, current (separately for solar panel / load), battery state of charge, accumulated charge and discharge energy
• Easy to use buttons allow the user to manually select the battery type (sealed, flooded or gel) and program load settings (e.g. set timers for lighting, fans, pumps etc).
• Current limiting function (20A) allows the possibility of adding more solar panels to your solar system in the future
