5.3Storage System Connection Mode
5.3.1 Difference between Traditional Photovoltaic System and Storage System
Growatt SP 2000 series storage plus can be connected to single-phase grid-connected inverter to build a
storage-function system. Every string can be connected to one SP 2000. If you have double MPPTs to be connected
to SP 2000 respectively, every MPPT connects one will be feasible.
The traditional single-phase inverter system is shown as below:
Chart 5.6
Traditional single-phase inverter system consists of PV panels, PV inverter, load and power grid. The inverter
supplies the power generated by solar panels to household load. Extra electricity will be fed to the grid when
generated power is more than family load needs; otherwise inverter will get power from grid for supplement.
PV Storage System with the storage plus is shown as below:

Page 16/43
Chart 5.7
Compared with the traditional photovoltaic system, a storage-control device SP 2000, battery cells and a sensor for
information collection have been added into the Storage System (Notice: Sensor must be installed close to the grid
side).
5.3.2 Storage System installation with Dual-MPPT inverter
As for connection with single MPPT inverter, you can refer to 6.4.1 for installation. When installing the storage
system with dual MPPT inverter, if you just upgrade one MPPT to execute storage function, you are advised to
install the Storage Plus to the MPPT which generates greater power. Installation diagram as below:
Chart 5.8
Connect one PV string to the Storage Plus, and then to one MPPT of the inverter. While connect the other PV
string direct to the input terminal of the inverter.
If both MPPTs are to be upgraded to execute storage function, installation should be done as below:

Page 17/43
Chart 5.9
Notice: During the installations above ,please pay attention to the installation position of the sensor.
5.3.3 Installation steps of Upgrading existing PV system
Steps to add the storage system into the original installed PV inverter system are shown as follow:
Step 1: If inverter is equipped with a DC switch, please turn the DC switch to Off and ensure that the DC switch on
the Storage Plus stays at Off status at the same time. Then unplug the terminal connected to the inverter
from PV panels, and connect it to the Input terminal of Storage Plus.
Chart 5.10
Step 2: Connect the output of Storage Plus to the input of your PV inverter, as the diagram show:
Chart 5.11
Step3: Connect the battery to Storage Plus, you can refer to 5.4.7 for connection of battery.

Page 18/43
Chart 5.12
Step 4: Buckle the sensor to the residential user inlet wires, at the same time plug the AC PLUG on the Storage Plus
to electricity, and finally the entire system is ready to work smoothly.
Chart 5.13
5.4 System Electrical Connection
5.4.1 Storage Plus AC power supply connection
Preparations before connection:
A measure the grid voltage and frequency and make sure the voltage is 220/230Vac , the frequency is 50/60Hz in
single phase.
B Connect the AC cable with safety regulation to the AC PLUG section.
Chart 5.14

Chart 5.15
5.4.2 Storage Plus PV Connection
1. Insure correct polarity before connecting the PV input. Reverse positive or negative polarities may cause
unrecoverable damage. Insure that the short-current of PV string should not exceed the max input current of
the Storage Plus.
2. The diagrams below show the PV connection way. Attention, the connectors (male and female connectors)are
in paired. The connectors for PV arrays and inverters are H4 or MC4 standard.

Remark: We suggest you use the cable ≥4mm2/12 AWG to connect.
5.4.3 Connection of Temperature detection for Lead-acid battery
1. Please confirm the battery type before connection. For the installation of Lead-acid battery, you need to use
the temperature sensor, while lithium battery can connect direct to BMS.
2. Open the cover plate at the terminal before connection.
Chart 5.18
As pictured above, with the top cap open, take the white 2PIN female plug of battery temperature sensor through
the cover plate, and insert it into the 2PIN male plug marked with NTC/SENSOR.
Remark: temperature detection wire (1.5m in length) specifications: UL1332 26 AWG TS 200℃ 300V.
