SolaX Power X3-Hybrid Series Installation Guide

SOLAX X3-Hybrid series inverter provides the parallel connection which could make
ten inverter maxiumumly connected in one system to deliver larger output power.
In order to delivering power to some important large loads steadily both in on-grid
or off-grid status, the hybrid system should connect a large changeover device to
achieve parallel functions in any conditions.
2 Introduction
X3-EPS-BOX-P5-I
Now SOLAX launch a changeover devide, called “X3-EPS parallel Box”, which chould
achievechangeover function between on-grid condition and off-grid condition. Besides
it has aninternal junction box which could connect ten EPS ouput cables of inverters.
X3-EPS parallel box models:
X3-EPS-BOX-P10-I
X3-EPS-BOX-P5-E
X3-EPS-BOX-P10-E
I & E mean different areas of application.
X3-EPS-BOX-P5-I and X3-EPS-BOX-P10-I ( I version for short below) applies to
the wiring rules which requires Neutral line of aleternative supply must not be isolated
or switched. ( applies to wiring rules AS/NZS_3000:2012 for Australia and New Zealand.)
X3-EPS-BOX-P5-E and X3-EPS-BOX-P10-E ( E version for short below)applies to
the wiring rules that requires live lines and Neutral line of alternative supply must be
disconnected after the grid is off. ( applies to most countries.)
P5 & P10 mean maximum admissible inverter quantity.
X3-EPS-BOX-P5-I and X3-EPS-BOX-P5-E allows that 5 X3-Hybrid inverters mostly could
be connected in the system.
X3-EPS-BOX-P10-I and X3-EPS-BOX-P10-E allows that 10 X3-Hybrid inverters mostly
could be connected in the system.
1 Important Instructions
Symbols on the Type LabeI
Danger of high voltage.
Danger to life due to high voltage of control box!
Danger .
Risk of electric shock!
Observe enclosed documentation.
The control box can not be disposed of together with the
household waste.
Do not work on this control box until it is isolated from battery
and mains suppliers.
Warning!
All electrical installations must be carried out in accordance with
the local electrical standards.
All operations described in this manual only can be performed by
qualied electricians.
Authorized service personnel must disconnect all power from X3-
EPS parallel box before attempting any maintenance or cleaning or
working with X3-EPS parallel box.
Warning!
The hybrid on&off grid parallel system is extremely complex, and
any small misoperation may cause the system running failed and
it is hard to find the misoperation, so any operations are
prohibited before reading this guide carefully.
Warning!
A large amount of cables will be to connected in the parallel
system,so make sure all cables are in good condition and that
cables are not undersized. Do not use any damaged or
substandard cables in the system.
