Our latest version 3A, 5A & 10A automatic 12V/24V GAMMA 2.0 Solar Charge Controller series are especially designed for reliability and affordability.  It is perfect for small & medium solar systems with the need of a multi functions and programing features.

Support On Grid (grid-tie) solar panel with a maximum PV voltage input of 50V.

Selectable battery types: Gel, Sealed (AGM) and Flooded battery options.

The GAMMA regulation circuit provides series regulation to prevent single cell overheat problems of short-circuited solar panels.  The terminal section has been replaced by a rugged, well profane 6mm square terminal block.

The melting fuse of the predecessor has been replaced by a fully electronically protected circuit.

With digital display and 5 LED indicators to display charging in progress, battery SOC, load disconnect, overload status and more.

Leisure and rural electrification systems are the typical applications for this product. It is a perfect solution for cost-sensitive systems which require state-of- the-art system management.

GAMMA equips with intelligent dual function timers enhance the flexibility of lighting system.
