12V 24V Solar Controller With Display

Constructed from robust ABS plastic, this solar charge controller automatically detects and regulates for 12V or 24V battery systems. It maintains stable operation across a wide ambient temperature range (-35°C to +60°C) and consumes under 10mA when idle. Technical parameters include maximum photovoltaic input voltage less than 50V, and fully adjustable voltage thresholds: discharge recovery (default 12.6V), discharge cutoff (default 10.7V), and float charge (default 13.7V). A built-in 5V/3A USB output provides auxiliary power for portable devices. The digital display presents live system metrics and allows straightforward access to configuration menus — enabling users to verify correct operation and tailor behaviour to their battery type and usage pattern. Its eye-catching blue-green enclosure stands out visually against standard grey/black enclosures, aiding fast identification during commissioning or maintenance. Suitable for home solar kits, mobile workshops, rural telecom repeaters, marine auxiliary systems, and small-scale agricultural pumps, this controller offers dependable regulation where grid access is limited or unreliable. As a replacement solution, it delivers improved diagnostics, finer control, and stronger build integrity versus obsolete models commonly found in older UK off-grid setups.
