Our latest version 3A, 5A & 10A automatic 12V/24V GAMMA 3.0 Solar Charge Controller with USB power 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.

Automatic selec battery types: Gel, Sealed (AGM) and Flooded batteries.

Designed to power 5VDC (1.2A) with a USB Power Socket.

The GAMMA 3.0 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  The terminal section has been replaced by a rugged, well profane 6mm square terminal block.

The melting fuse of the predecessor has been replaced by a fully electronically protected circuit.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 3 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 3 voltage system (12V, 24V and 5V) and function timer for both 12V (24V) abd 5V (USB) enhance the flexibility of lighting system.  The 1st of it class USB lighting day & night timer system.
