USER MANUAL
INTRODUCTION
processor with special algorithm is used to achieve high
efficiency and best possible harvest from sun.
Differential mode
filters are used for filtering 50 Hz current
from inverter carrier frequency,, .
Common mode EMC
filters are used for EMC interferences
filtering. THD for
Surge and Burst
protections are used for protecting inverter
from lightening phenomena’s and grid over voltages. It
is strongly recommended to install external overvoltage
protection class II on AC side, it is also condition for the
validity of Limited Warranty.
Solar Micro inverter is in standby until there is insufficient
irradiance and a specific minimum voltage is present in
the inverter. The consumption in standby is 0W. The micro
inverter starts to fully operate when the sun begins to
supply energy and the voltage in PV module reach 22Vdc.
When the voltage drops below the minimum voltage value
(15Vdc) feed-in mode ends and the inverter switches off.
