• Keep away from flammable, explosive materials to avoid fire disaster. The installation
place should be away from humid or corrosive substance.
• Authorized service personnel must use insulated tools when installing or working with
this equipment. PV modules shall have an IEC 61730 class A rating.
• Never touch either the positive or negative pole of PV connecting device. Strictly
prohibit touching both of them at the same time.
• The unit contains capacitors that remain charged to a potentially lethal voltage after the
MAINS , battery and PV supply has been disconnected.
Hazardous voltage will present for up to 5 minutes after disconnection from power
supply.
• CAUTION-RISK of electric shock from energy stored in capacitor, Never operate on the
inverter couplers, the MAINS cables, Battery cables, PV cables or the PV generator when
power is applied. After switching o ffthe PV , battery and Mains, always wait for 5minutes
to let the intermediate circuit capacitors discharge before unpluging DC , battery inplug
and MAINS couplers.
• When accessing the internal circuit of inverter, it is very important to wait 5 minutes
before operating the power circuit or demounting the electrolyte capacitors inside the
device. Do not open the device before hand since the capacitors require time sufficiently
discharge!
INTRODUCTION
The inverter can be used to optimize self consumption, store in the battery for future use
or feedin to public grid. Work mode depends on PV energy and user’s preference. It can
provide power for emergency use during the grid lost by using the energy from battery
and inverter (generated from PV).In addition, the parallel function is available
(off grid model).

Work Modes
Hybrid Inverter provides multiple work modes based on different requirements
Work modes: Self-use
1.When PV, Grid, Battery is available:
A. Solar energy provides power to the loads as first priority, if solar
energy is sufficient to power all connected loads, solar energy
excess power will provides to charge battery, and then reduntant
power will feed to grid.
B. Solar energy provides power to the loads as first priority ,if solar
energy is not sufficient to power all connected loads, battery energy
will supply power to the loads at the same time.
C. Solar energy provides power to the loads as first priority ,if solar
energy and battery are not sufficient to power all connected loads,
utility energy (Main Grid) will supply power to the loads with solar
energy at the same time.
2 .When PV, Grid is available（without battery):
A. Solar energy provides power to the loads as first priority ,if solar
energy is sufficient, the excess power will feed to grid.
B. Solar energy provides power to the loads as first priority, if solar
energy is not sufficient to power all connected loads, Grid energy
will supply power to the loads at the same time.
3 .When PV, Battery is available（Grid is disconnected):
A. Solar energy provides power to the loads as first priority ,if solar
energy is sufficient to power all connected loads, solar energy will
provides to charge battery.
B. Solar energy provides power to the loads as first priority ,if solar
energy is not sufficient to power all connected loads, battery energy
and solar energy will supply power to the loads at the same time.

Load
Work modes: Peak shift
1. When PV, Grid, Battery is available:
A. On charge time, solar energy will charge battery as first priority.
The excess energy will supply power to the loads.If solar energy is
sufficient to supply loads and charge battery,and If there's still some
extra energy, then the excess power will feed the power to grid
B. On charge time, solar energy will charge battery as first
priority.then the excess solar energy will supply power to loads.If
solar energy is not sufficient to charge battery and supply loads, grid
will supply all the connected loads with solar energy together.
C. On discharge time, solar energy provides power to the loads as
first priority, if solar energy is sufficient to supply loads ,and if
there's still some extra energy from solar energy ,then the excess
power and battery will deliver the power to the grid at the same
time.
D. In the period of no charge or discharge, the solar power supply
loads at first priority , excess energy to the grid.
2. When Grid, Battery is available(PV is disconnected):
A. On charge time, grid will charge battery and supply power to the
connected loads at the same time.
B. On discharge time, if load power is less than battery power,
battery will supply power to loads as first priority, the excess power
will be feed to grid.
C. On discharge time, if load power is more than battery power,
battery and grid will supply power to the loads at the same time.
Work modes: Bat priority
1. When PV, Grid, Battery is available:
A. Solar energy will charge battery as first priority, if solar energy is
excess, the excess power will supply load. If there's still some extra
energy, then the excess power will feed the power to grid .
B. Solar energy will charge battery as first priority, if solar energy is
excess, the excess power will supply load.If solar energy is not
sufficient to charge battery and supply loads, grid will supply power
to loads.
2. When Grid,Battery is available（PV is disconnected):
Grid will supply power to load and charge battery at the same time.
