5.2 Installation requires tools and RJ 45 terminal sequence of
the LAN line
J. Do not install the machine near television antenna or any other antennas and
antenna cables.
K. Don't install the machine in the living area.
L. Be sure that the machine is out of the children's reach.
M. Taking the battery fixing space into account, about the dimensions please
reference user manual.
N. The inflammable and explosive dangerous goods must not be placed around
battery in case of cause serious danger.
When installing, we need to use tools as follow, prepare the follow tools before
installing:
No.

5.3 Installing the inverter
There're two types of sensors for use with Growatt SPH. One is wired current sensor,
one is meter sensor, if you choose wired sensor or meter. Before installing you should
know something that as below:
The cable of wired sensor and meter is suggested not longer than 15m. So you need to
consider the length between SPH with combiner box for the sensor should be installed
in the live line.

Attention:
Battery installation requirement
As the system refer to battery use, we must make sure ventilation of the service
environment and temperature control in order to prevent the danger of battery
explosion, battery recommended installation environment must be strictly in
accordance with the specification,If the chosen PV modules needs to positive or
negative ground connection, please contact with manufacturer for technical support
before installation.
PV modules Capacitive Discharge Currents
PV modules with large capacities relative to earth, such as thin-film PV modules with
cells on a metallic substrate, may only be used if their coupling capacity does not
exceed 470nF. During feed-in operation, a leakage current flows from the cells to
earth, the size of which depends on the manner in which the PV modules are installed
(e.g. foil on metal roof) and on the weather (rain, snow). This "normal" leakage current
may not exceed 50mA due to the fact that the inverter would otherwise automatically
disconnect from the electricity grid as a protective measure.
A complete grid-connected system of SPH consists of PV modules, SPH inverter,
battery, utility grid and other components as following:
