Grid Tie 500W - LED Indicators Explained; Red LED Indicator Meanings; Green LED Indicator Meanings

LED Indicators
1. Red LED indicator lights up under any conditions include but not
limited:
a) Low-voltage protection (DC input voltage lower than Min. input
voltage of inverters),
b) Over-voltage protection (DC input voltage higher than Max. input
voltage of inverters),
c) Over-temperature protection (inverters will shut down for power
output when temperature of body of inverters higher than 65-70℃,
and inverter will be automatically restart up when temperature
down to 40-50℃),
d) Power grid fault protection when 110VAC or 220VAC grid power
outage and/or tripped,
e) Islanding protection: inverter will be automatically shut down for
power output when disconnect with power grid,
f) Short-circuit protection: inverter stops work when output line
short-circuits,
2. Green LED indicator lights up under any conditions include but not limited:
a) Green LED flash: adjusting for power output, MPPT operating for
tracking,
b) Green LED long light: indicates inverter locking-in Max. output power
operation status,
3. Please note that above operations only run at grid-connected status.
