1 Brief Introduction
1.1 Preface
This manual will provide the users who use the Growatt SPH Series of GROWATT
NEW ENERGY CO.LTD.SHENZHEN(Short for Growatt New Energy as below) with
the detailed product information and the installation instructions. Please read this
manual carefully and put this manual on some place where is convenient to
installation, operation, obtain. Any modifications of Growatt new energy, we will
not notify the user.
Growatt SPH inverter must be installed by professional electrical personnel who
have obtained the certification of the relevant departments. We have two kinds of
energy storage machine for different battery one is for lithium battery and the other
is for lead-acid battery, we suggest: customer should decide which kind of energy
storage machine you want, Growatt can provide only lithium battery with energy
storage machine, customer can choose lead-acid energy storage machine with no
battery provide by Growatt while they can buy these battery from market easily.
Especially if customer choose energy storage system with lithium battery(which
must be provide by Growatt) but used for lead-acid battery or used lead-acid
battery for lithium battery model, it will be dangerous. Installer can install energy
storage machine of Growatt SPH Series rapidly and troubleshooting, build
communication system through read this manual carefully. If you have any
questions in the process of installation, you can login in and
leave some message. Or you can call our 24-hour service hotline [phone]
www.growatt.com
Growatt SPH Series is used to store energy generated by the photovoltaic cell
panels or energy from grid if it is allowed in the battery, also energy can be sent to
power grid through SPH for self consumption or when Grid power is lost, SPH can
be used as back up power.
SPH series has six kinds of type:
•Growatt SPH4000
•Growatt SPH4600
•Growatt SPH5000
•Growatt SPH5600
Note: we describe this series as “SPH” as below.
•Growatt SPH3000
•Growatt SPH3600
Note: In different country,we provide different power.Such as in Germany,we can
provide SPH3000~SPH4600,but we don’t provide SPH5000 and SPH6000.

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
