damaged. The following items inside of package would be received.
01.All-in-one solar system 02.User manual
4.2 PREPARATION.
Please remove the two screws on the back cover of the device before opening it.
4.3 INSTALLATION SITES SELECTION.
Consider the below points before selecting where to install:
1.Do not mount the system on the surface of flammable construction materials.
2.Mount on the surface of solid material.
3.Install this system at a visible place in order to allow the LCD display to be read at all times.
4.For proper air circulation and heat dissipate, make sure there is 20cm distance from the
two side, 50cm distance from bottom of the unit.
5.The ambient temperature should be between 0°C and 55°C to ensure optimal operation.
6. The recommended installation position is to be adhered to the wall vertically.
7. Be sure to keep other objects and surfaces as shown in the diagram to guarantee
sufficient heat dissipation and to have enough space for collecting wires.
4.4 AC INPUT/OUTPUT CONNECTION
CAUTION! Before connecting to AC input power source, please install a separate AC breaker
between system and AC input power source. This will ensure the system can be securely
disconnected during maintenance and fully protected from over current of AC input.
The recommended spec of AC breaker is 3.2KVA 32A. There are two terminal blocks with “IN”
and “OUT” markings. Please do NOT connect input and output connectors wrong.
WARNING! All wiring must be performed by a qualified personnel. It's very important for
system safety and efficient operation to use appropriate cable for AC input connection. To
reduce risk of injury, please use the proper recommended cable size as below.

WARNING: Because this system is non-isolated, only three types of PV modules are
acceptable: single-crystalline, poly crystalline with class A‐rated and CIGS modules. To
avoid any malfunction, do not connect any PV modules with possible current leakage to
the system. For example, grounded PV modules will cause current leakage to the system.
When using CIGS modules, please be sure NO grounding.
CAUTION: It’s requested to use PV junction box with surge protection. Otherwise, it will
cause damage on system when lightning occurs on PV modules.
PV Module Selection:
When selecting proper PV modules, please be sure to consider below parameters
1.Open circuit Voltage (Voc) of PV modules not exceeds maximum PV array open circuit
voltage of system.
2.Open circuit Voltage (Voc) of PV modules should be higher than minimum battery voltage.

mode
AC: (default) AC will provide power to the load as the first priority,solar
charging the battery. When solar energy is insufficient,AC and solar
energy charge the battery at the same time. When AC is unavailable it
will be powered by solar energy or batteries.
Solar: Solar energy provides power to the loads as the first priority.
When the solar energy is sufficient,the extra energy will charges the
battery. When solar energy is insufficient for load,batteries and solar
will supply power at the same time. When solar energy and batteries
are insufficient or solar energy is unavailable,AC power supply power
to the load.
Battery: Battery provides power to the loads as the first priority. AC
provides power to the loads when battery voltage drop to low-level
warning voltage or setting point,and the AC power will charge the
battery. When the battery is fully charged,battery provides power to the
load again.
Solar + AC: Solar energy provides power to the load as the first priority.
If solar energy is not sufficient to power all load,AC energy will supply
power the load at the same time

Grid
Select “On Grid” in Grid setting: when in On Grid mode solar will power
loads first, then extra power feed back to utility; When Solar power is
not enough, the utility will assist it to power loads.
Note: if the utility charging is selected to be”0A”,the grid connection
function will not be available.
Peak and
Valley
No charge1: optional
No charge2: optional
NOTE: when peak valley no charging, utility will stop charging. If pv,
battery and utility exist at the same time, the PV will only charge the
battery and the load is powered by utility and the grid-tie function is not
available

Beep: Optional buzzer sound
Factory: Optional factory reset
CT sensor: CT power calibration, set the range of 500-3000,the
increment or decrement is 1 per click.
Choose the AC+PV mode first, then choose the“Out Side CT”(in
output side, when your loads power is big, PV will give more power to
supplement it, but the biggest power it can supplied is PV output rate
power)
Please note: The direction of the CT must be right. (CT is connected in
