HYBIRD SYSTEM: GRID TIE SOLAR SYSTEM WITH BACKUP

HYBIRD SYSTEM: GRID TIE SOLAR SYSTEM WITH BACKUP This is an integrated system of our company AST from two independent systems into a smart system include: - Solar On Grid System (GTSI): Produces energy from the sun into electricity 220V AC/50Hz to push into the grid. - Solar Off Grid System (ISCB): Storage energy from the sun to battery and converted into 220VAC/50Hz for priority load line when grid outage. Also the ISCB is also very convenient for use where there is no electricity grid as islands and mountains.

Describe activities: When the grid: GTSI working in the ready mode. The ISCB in Bypass mode: (Connect the priority load line directly to the electricity grid.) * Daily battery always is being charged from the sun through the ISCB with priority . In this time of GTSI not work. * When the battery is fully charged the ISCB stop charging and GTSI will automatically switch to work mode: Converts DC power from Sola panel into AC 220V (voltage, frequency, phase polymerization) to mix with grid. When the power off: The GTSI will stop working after 0.1 seconds to ensure the safety of the grid system. ISCB will automatically switch from bypass to inverter DC backup taken from the Battery and Solar power into 220V AC supply for priority load. From the diagram at Grid connection point that we find: Electricity purchased from the grid is the number on W0 meter. The production of electricity from the sun is the value on W1. Power consumption of household consumption on both transmission lines are the numbers on the W2 meter. And W2=W0+W1 Thus power is purchased from the grid W0 is alwways less than the power consumption value W2 => In case of W1 is greater than W2, W0 will have a negative value this represents the fact that we supply (selling) power from the sun back to the national grid. In addition to the Grid-Tie Solar Inverter and Inverter-Solar Charger, we also have other green energy products like: Solar Street Light, Solar Charge Controller, Solar Regulator, the Solar Panel rotator (used for solar tracking), Smart, Wind power and Solar panel with different power levels. Besides, we also have other products like Backup generator (UPS offline), the AC-DC inverter (included standard wwave form True/Pure sine inverter and sine waveform simulation - Modified sine wave inverter), DC-DC converter, AC-DC (Automatic charger, rectifier), 1-phase and 3-phases Automatic voltage stabilizer, online UPS, others integrated product as demand.
