The photovoltaic
voltage is too high
Check whether too many photovoltaic
modules have been connected in series in a PV
string and therefore the voltage (Voc) of the
PV string is higher than the maximum input
voltage of the inverter. In this case, reduce the
voltage of the PV string by adjusting the
number of photovoltaic modules so that it
adapts to the voltage range of the inverter.
Once the necessary changes have been made,
the inverter returns to its normal operating
state.
The LLCBus voltage is
too high and has
triggered the hardware
protection.
ID09 - ID12 are internal faults of the inverter;
switch it off, wait 5 minutes and then switch it
back on again. Check if the problem has been
resolved.
If not, contact ZCS Technical Support.
The voltage increase is
too high and has
triggered the hardware
protection
The BuckBoost current
is too high and has
triggered the hardware
protection
The battery current is
too high and has
triggered the hardware
protection
The GFCI sampling
value between the
master DSP and slave
DSP is not suitable.
If the fault occurs occasionally, the likely
cause is that the external circuits are
occasionally in an abnormal state. Once the
fault has been eliminated, the inverter
automatically returns to its normal operating
state. If the fault repeats itself often and lasts
for a long time, check whether the insulation
resistance between the PV string and the
ground is too low, also check the insulation
conditions of the PV cables.
The photovoltaic
current is too high and
has triggered the
hardware protection
ID14-ID15 are internal faults of the 1PH
HYD3000-HYD6000-ZSS inverter; switch it
off, wait 5 minutes and then switch it back on
again. Check if the problem has been resolved.
If not, contact ZCS Technical Support.
The grid current is too
high and has triggered
the hardware
protection
The input current is not
balanced.
Check the settings of the photovoltaic Input
mode (parallel/independent mode) of the
inverter. If this is not correct, change the input
mode.
