W027 Battery open
Check the battery for voltage using a multimeter.
Ensure all wires are correctly installed to inverter
Inverter is running beyond maximum output.
W029 Inverter voltage high
Restart the inverter. If the error persists, contact the
distributor.
W031 Load VDC high
Restart the inverter. If the error persists, contact the
distributor.
CODE STATUS DESCRIPTION
0×00 Standby Inverter is in standby status
0×02 FW Updating Inverter is updating firmware
0×04 PV On-grid
When grid-tied, the PV system operates in two modes:
1. Excess solar power is fed into the grid when production exceeds
demand. 2. It draws power from the grid when solar generation is less
than demand.
0×08 PV Charge
Solar power exclusively charges the battery, with a maximum capacity
limited by the battery's charging power. This mode commonly activates
when the EPS switch is turned off.
0×0C PV Charge On-grid
In hybrid mode with “PV & AC Take Load Jointly” enabled, when solar
power surpasses load requirements, it's initially utilized to power the
load. Any solar energy surplus beyond the load is then directed to
charge the battery.
0×10 Battery On-grid
In hybrid mode with 'PV & AC Take Load Jointly' enabled, the inverter
uses the battery to supply power to the load. If the battery capacity is
insufficient to meet the load demand, the deficit is supplemented by
drawing power from the grid.
0×11 Bypass
In off-grid mode, the inverter solely relies on grid power to supply the
load. Solar power is dedicated exclusively to charging the battery,
limited by the maximum charging capacity of the battery.
0×14 PV & Battery On-grid
In hybrid mode with 'PV & AC Take Load Jointly' enabled:
1. When solar power is less than the load power, both solar and battery
sources jointly supply the load. 2. The inverter operates in the AC First
time period. 3. During the AC Charge time period, if the AC Charge
requirement is not fulfilled, the inverter continues in the AC Charge
mode.
0×19 PV Charge + Bypass
In off-grid mode with 'PV & AC Take Load Jointly' disabled, the load is
exclusively supplied by grid power. Solar power is dedicated solely to
charging the battery and is limited to the maximum charging capacity
0×20 AC Charge Grid power is supplying load and charging battery simultaneously.
0×28 PV & AC Charge
Battery is being charged by solar and grid power simultaneously while
the load is supplied by grid power.
0×40 Battery Off-grid Grid power is cut, and battery power is used to supply the load.
0×80 PV Off-grid
Grid power is cut, and the inverter supplies the load with available
