6 Operation Mode For Grid Connected Inver - SOYO Grid Series Instruction Manual

.
3 6 The working mode of Grid tied Micro Inverter
【 】
1 micro inverter system could monitor and autorun System could according to
the output power of pv modules array to determine whether to Grid Connected or
.
not System operation process includes power on grid connected standby mode
normal shutdown and battery opc mode
-
【 】
2 Grid Connected
-
Grid connected power mode refers to the micro inverter converts photovoltaic
components of direct current dc to alternating current ac power grid in order
to ensure maximum power output the system adopts MPPT control method
can guarantee the system in any sunshine time and temperature conditions
always make pv array maximum power output state
【 】
3 tandby mode
Standby refers to the output voltage of solar module is below a certain value or
the grid parameters such as voltage frequency temperature is beyond the scope
of work permit grid inverter in the standby state
【 】
4 ormal shutdown
When the light intensity decrease the output power of solar module became
.
weak When power is low the machine will enter the standby mode when the pv
module voltage lasts a minute under working voltage or the voltage of photovoltaic
modules is lower than the shutdown voltage output will shut down and go in
shutdown state
【 】
5 Battery opc mode
The input dc side of this system could be connect with battery
the machines will get into opc mode automatically
for eighty percent of the total power to ensure that the machine could prolonged
Work under the grid
.
4 Malfunction and processing
When the fault indicating lamp light the micro inverter will stop automatically
The handling method please refer to section 3 4
