Why we need off-grid system?
So far , there are many areas in the world where there is no electricity or the electricity supply is extremely short and unstable. Off-grid PV system can solve these problems.
Compared with traditional diesel generation, the off-grid system is cleaner, greener and most cost effective. For people living in remote areas, electricity shortage areas or off-island areas, the off-grid PV system is a good choice.
How does the Off-grid PV system work?
The unstable DC power which is generated from panels through solar off-grid system is converted to single phase pure sine wave AC power and supply to loads with power charging battery automatically. When solar power is lacking, the battery will serve as complte power source. Solar offgrid system supports grid or AC generator as back up .
Uninterpreted power supply, environmentally friendly, no pollution
• Off-grid inverter is integrated with controlling and inverting functions, featured with high efficiency, good compatibility, reliability and also easy installation.
• System has multiple functions with automatic switch mode while working.
• High efficient system with long lifetime.
