Display on the
LCD display
Explanation
Normal The PV solar inverter works
normally.
When the delivered performance
of the PV panel is sufficient
(500 VDC > PV >120 VDC), it
supplies the energy to the
mains.
The green LED lights up and
shows that energy is being fed
into the mains.
Standby If the performance is insufficient
(60VDC < PV < 100VDC), the PV
solar inverter switches to
standby operation and searches
for a connection to the mains.
It has only limited power from
the PV module to monitor the
internal system state.
Error The internal regulator continually
monitors the system state and
adjusts it.
If the PV solar inverter registers
malfunctions such as mains
problems or internal errors, the
display will this, and the red LED
will light up.
EPO Emergency power off (EPO).
