◆Product description
ShineLink adopts a device-gateway-server-client architecture model, which
uses gateways and servers to link household energy equipment with
homeowners to realize the entire function of monitoring, analysis, and
scheduling. Among them, GroBoost could control the temperature of the water
heater, and work automatically when the solar system has surplus power
exporting to the grid to maximize solar self-consumption.
Figure 1-2
GroBoost is a power regulator to adjust its power output automatically
based on resistive loads through wireless commands. With the ShineLink
system, it communicates with ShineLanBox through RF signal, accepts
commands to adjust power output, and realizes system energy distribution and
scheduling. The diagram of one of its application scenario is shown in Figure

3
1-2, in which the Inverter is communicated with the meter through RS485, and
communicate with the LanBox through ShineRFStick.
This application scenario is suitable for the Growatt new generation
inverter, like MIN, MID, MOD, SPH and SPA series, which could support to
upload the energy meter date to the server.
Figure 1-3
The diagram of another application scenario is shown in Figure 1-3, the smart
meter data is transmitted wirelessly to the LanBox through RailLog, which is
suitable for the -s series inverter which can’t upload the energy meter data to
the server.
◆ GroBoost Interface
As shown in Figure 1-4, the device has four indicator lights, four function
buttons and three waterproof connector, corresponding to different wiring input.
The functions and definitions are shown in Table 1-2.

二、Installation
Notice:
⚫Make sure to read the instructions to understand product information and
safety precautions before installation;
⚫The installer must use insulated tools and wear safety equipment during
the installation procedure；
⚫Construct sun and rain shelters to avoid GroBoost directly exposed to
sunlight and rain.
Figure 2-1
◆Installation Process
⚫Fix the wall-mounted bracket hanging on the wall with screws, drill holes in
the wall after positioning the four screw holes, put the plastic expansion

7
tube, and screw into the wall, to fix the wall hanging.
Figure 2-2
⚫There are four screws on the bottom cover of the whole machine,
please use a screwdriver to dismantle the screws.
Figure 2-3
⚫Remove the lower cover and start to wire it.
Figure 2-4
Loosen these screws

⚫The wire harness passes through the corresponding three terminals and
screwed themon the terminals. A 5 pin three-phase power input terminal is
for power input line, 3 pin power output terminals is for loads, and the 3 pin
RS485 and 12Vdc terminals are for the communication of the future
application.
Figure 2-5
⚫Screw the wire on the male terminal, connect it to the corresponding
female socket of the device, and fix screws on both sides of the terminal to
fix the terminals.
Figure 2-6
⚫Adjust wiring distance and screw the four screws fixing the sealing lower
cover to fix the lower cover.

9
Figure 2-7
⚫Adjust the length of the power and load lines, screw the covers, adjust the
wiring head to reduce the space, and make the sealing degree higher.
Figure 2-8
⚫Fix the GroBoost on the wall, and tighten the screws on the side.

10
Figure 2-9
GroBoost Notice for wiring:
⚫Remove the lower cover of GroBoost, and you need to pass the wire
harness through the corresponding three terminals to prevent the wire
harness from being twisted.
⚫Use a no less than 4mm2 copper core wire for the power line, ground line,
and load line. After stripping the wire, make sure that the wire is not too
long, generally 10mm.For 485 communication lines please use shielded
twisted wire.
⚫Put the stripped wire into the terminal and use a flat-blade screwdriver to

11
fix the wire,and then connect it to the device.
⚫The antenna needs to be led out of the device to prevent signal shielding.
三、Multiple Work Modes
◆Load Wiring
The diverse load situation corresponds to different wiring ways. In addition, if
the immersion heater doesn’t have a temperature sensor, and the GroBoost
needs to use the temperature sensors (Pt1000). The following table 3-1 shows
the wiring diagram of a diverse load situation.The following figure is the overall
detailed wiring diagram.

fixed power output mode. The adjustable power output mode is used for
the PV linkage application,the power output will be adjusted for the
resistive load according to the surplus solar power.
⚫Three temperature sensors are related to the phase L1/L2/L3 separately.
The T1 terminal is related to phase L1, the T2 terminal is related to phase
L2 and the three-phase load, T3 terminal is related to phase L3.

◆Installation Check
After the wiring is completed, corresponding inspections are required to ensure
that the equipment will not be damaged due to incorrect wiring, or cause
leakage and endanger personal safety. The following table 3-2 is what needs
to be checked:

◆Work Mode
GroBoost has two main working modes:
Smart mode and PV linkage mode. In addition, the mandatory mode can
be triggered by pressing the key.
Smart mode:
The GroBoost will accord to the timing period and the temperature being
set to work, which has 5 groups of settable time periods. During the smart
mode, the device will work based on its rated power, however, the power
output of the phase L1 is a settable.

18
PV linkage mode:
GroBoost can get a real-time power flow through the ShineLink system.By
setting the execution strategy, the GroBoost will automatically work and adjust
its output power when there is a certain power exporting to or importing from
the grid, to make full use of the solar energy and maximize the solar
self-consumption. In addition,there is also a thermal protection function to
guarantee the water temperature during the time period and temperature point
being set when the offline happens or solar energy is insufficient.
Mandatory mode:
Triggered by manual button, and it could enable the GroBoost to work
forcedly, and stop until it reaches the maximum temperature (default
temperature is 65 °C), often being used in an emergency situation. For security,
the maximum duration of mandatory mode is 2 hours by default.
◆Display and Setting
GroBoost has four LED lights and four function buttons, which work with
multiple devices at the same time. The operation condition and mode of the
devices can be monitored and set by the ShineSever or ShinePhone platform,
and can also be achieved through the basic indicator lights and buttons. Each
LED light and button correspond to a load, and the status of LED light will
indicate different working status, as shown in Table 3-3:
