4. Select priority mode: PV for photovoltaic power supply priority, AC for AC power
supply priority.
5. Press and hold the on/off switch to switch on the device, and connect to AC power
supply mains.
6. Set the SOLAR switch to ON, to enable charging from solar cells.
7. Connect the external devices (make sure the devices are turned off at that time).
Turn on the external devices one by one.
ON/OFF
1. Make sure the battery has been connected properly (correct polarization, matching
voltage).
2. Make sure the solar panel has been connected properly (correct polarization,
matching voltage).
3. Press and hold the on/off switch for about 3 seconds; the inverter will turn on.
4. Set the solar switch to ON, the device will enable charging.
5. Connect to power supply mains.
AC priority (AC power supply priority)
1. Turn on: if the AC power supply is available, the inverter will begin work in AC power
supply mode, and at the same time charge the battery as well. If the AC power
supply mains is abnormal or not available, press and hold the on/off button for about
3 seconds; the device will start and enter inverter mode. When AC power supply
mains recover, the device will automatically enter AC mode and start charging the
battery.
2. Turn off: press and hold on/off button to turn off the inverter. The outputs will be cut
off, the device will be charging battery and will not switch to inverter mode again.
PV priority (photovoltaic supply priority)
1. Rebooting - in case of solar energy power interruption:
•
if the AC power supply mains is available, the external device will be supplied
from the AC power supply mains
•
when PV power supply recovers and AC power supply mains is available, if the
battery level is high enough, the inverter will switch to battery mode (AC power
supply mains at standby);
•
Once the PV energy is recovered, and the battery level is not high enough, solar
panels will be only charging battery. In such case, press and hold on/off switch for
about 3 seconds to supply external devices from PV energy.
2. Turn off: after turn off, the device will not switch to inverter mode.
WORKING PRINCIPLE
AC priority mode (AC power supply mains priority)
1. AC power supply mains is available: the external devices will be supplied from the
AC power supply mains. Solar cells will be charging battery.
2. In case of AC power supply mains overrun of cut off: battery and solar cells will
