inverter is still in a standby mode at this moment, and is waiting for the mains
power to restore and the input of PV energy.
When the battery voltage is charged to 52V, the PV inverter will automatically
switch back to the inverter power output to supply power to the loads.
Remark:
The advantage of PV power saving mode is to maximally supply power to
loading devices by using solar energy, while the mains power is only used as a
backup power supply under extreme conditions. Accordingly, PV power
saving mode is suitable to use at the places where the mains power supply is
unstable or unavailable, such as in the remote mountain areas, plateau,
yachts, vehicles, etc. However, batteries might stay in a relatively low level
under extreme weather conditions for a long time. Therefore, we suggest
users to manually switch the mode into UPS and wait for a better weather
condition before switch it back to a PV mode.
3.3 System Initial Setting
All series of product models contained in this User Manual are having the
inverter output of 230V/50Hz in the PV power saving mode as factory default
setting. Users can adjust the setting values via the front panel “Setting” function
keys (Refer to Section 3.4 for setting procedure) to suit different environment or
individual needs. After the new setting is completed, the PV inverter needs to be
switched off and then restarted, and the user's setting values are saved as the
initial setting values. And in the subsequent reset, the last setting values will be
applied as the system initial setting values.

Introduction
Step 1:
When reset the PV inverter, please turn it off beforehand. The battery
pack must be connected to the inverter, whereas the mains power input can be
connected or not be connected and no loads should be connected with the PV
inverter.
Step 2:
After turning on the PV inverter's power switch to the “ON” position
and wait for the LED display to light up, press and hold the “Setting” button for
about 5 seconds with a no-conductive tool, and wait until the PV inverter sounding
a long beeping alarm before releasing the setting button. It is an indication that
the PV inverter has entered to the setup program, in which the LOAD LED 1 is
lighted as an implication of the PV inverter is at the 1st layer setting.
Step 3:
Please refer to Table 3.1 to decide whether it is a desirable mode of
operation. If the LED light indicator shows it is the correct mode of operation,
please press and hold the “Setting” button for about 3 – 5s, until the PV inverter
making a beep sound and entering to the 2nd level output voltage setting
(LOADLED2 is lighted). If not, please press and hold the “Setting” button for about
1s then release. The light signal changes at each press, and after adjusting it to
the required mode, press the “Setting” button for about 3 – 5s until the PV inverter
is making a beep sound to indicate the completion of setting. At this time, release
the “Setting” button to enter to the 2nd layer of output voltage setting. The LOAD
LED 2 is lighted means that the PV inverter is entering to the 2nd layer setting.

The 2nd layer output voltage setting is described as follows:
Step 1:
Please refer to the LED signal comparison detailed in Table 3.2 to
determine whether a desirable output voltage is being selected. If the selection is
correct, please press and hold the “Setting” button for 3 – 5s until the PV inverter
sounds a beep before entering to the 3rd layer output frequency setting (LOAD
LED 2 is lighted). If not, please follow Step 2 for setting the output voltage.
Step 2:
Please press and hold the “Setting” button for about 1s and then
release it. In this way, the light signal changes for each press (Change of order:
208V→220V→230V→240V). And when adjusting it until the required voltage
