provide power to the external devices to ensure power supply continuity. If solar
panels energy is not sufficient or not available, external devices will be supplied with
power only from the battery.
PV priority mode (photovoltaic supply priority):
1. During the day (with ample sunlight) and power supply mains is available: solar
panels will provide power to loads, simultaneously charging the battery (power
supply mains at standby).
2. During the evening (or when the sunshine is not available), when the power supply
mains is available: system will provide power to loads from battery; discharge
battery until battery reaches low voltage protection level; then automatically enter
AC power mode and charge the battery till set value (reserved a certain power in
case of emergency situation, but will not charge the battery fully). The battery will be
fully charged by solar panels once the solar energy is recovered.
TURNING OFF STEPS
1. Turn off the loads one by one.
2. Press and hold the on/off button for about 3 seconds, the loads will be cut off.
3. Disconnect the AC power supply mains.
4. Set the solar switch to OFF.
5. Disconnect from the battery, if the device will not be used for a long time.
