Brief Introduction; Preface; Target Group - Growatt SPH Series Installation Manual

1 Brief Introduction

1.1Preface

This manual will provide the users who use the SPH TL BL-UP Series of GROWATT NEW ENERGY TECHNOLOGY
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.

1.2Target Group

SPH TL BL-UP 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 SPH TL BL-UP 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 www.growatt.com and leave some message. Or you
can call our 24-hour service hotline
1.3 Glossary
AC
Abbreviation for "Alternating Current"
DC
Abbreviation for "Direct Current"
Energy
Energy is measured in Wh (watt hours), kWh (kilowatt hours) or MWh (megawatt hours). The energy
is the power calculated over time. For example, your inverter operates at a constant power of 4600
W for half an hour and then at a constant power of 2300 W for another half an hour, it has fed
3450Wh of energy into the power distribution grid within that hour.
Power
Power is measured in W (watts), kW (kilowatts) or MW (megawatts). Power is an instantaneous
value. It displays the power your inverter is currently feeding into the power distribution grid.
Power rate
Power rate is the radio of current power feeding into the power distribution grid and the maximum
power of the inverter that can feed into the power distribution grid.
Power Factor
Power factor is the ratio of true power or watts to apparent power or volt amps. They are identical
only when current and voltage are in phase than the power factor is 1.0. The power in an ac circuit is
