DC Automatic Transfer Device

JNTECH set up in 2006, is a high-tech enterprise in Hefei, China, which integrate intelligent power electronics products’ R ;D, manufacture, sales and service, focus on manufacture of solar pump inverter, solar off-grid inverter relative solar products. All our products have passed CE and TUV certifications. Jntech solar pump system and off grid system are used in more than 50 countries in the world, especially in UNDP, UNHCR, UNICEF,OCHA, ICRC, NGO projects in Asia, Middle East, and African countires.

Assembled with multi-busbar PERC cells, the half-cell configuration of the modules offers the advantages of higher power output, better temperature-dependent performance, reduced shading effect on the energy generation, lower risk of hot spot, as well as enhanced tolerance for mechanical loading.
