Dangers of High Voltages and Large Current
Beware of high PV voltage. Please turn-off the DC switch of PV Panel output before and during
the installation to avoid electric shock.
Beware of high grid voltage. Please turn-off the AC switch of grid connection before and during
the installation to avoid electric shock.
Do not operate the inverter when it's working, only the LCD and buttons can be touched in
limited cases by qualified personnel, other parts of the inverter can be touched when the
inverter is under a safe state (e.g. fully shut-down).
Inspect the connections are good between inverter and PV, battery and grid during installation
to prevent damages or injuries caused by bad connections.
Inspect relevant existed wiring on-site of the installation is under good condition before
installation, operation or maintenance.
Make sure the inverter is well grounding, an operator should make sure himself is good
protected by reasonable and professional insulation measurements (e.g. personal protective
equipment (PPE)).
Do not connect or disconnect any connections (PV, battery, grid, communication etc.) of the
inverter when it's working.
Beware of large current of the battery output. Please turn-off the battery module before and
during the installation to avoid electric shock.
Do not open the inverter when it's working to avoid electric shock and damages from live
voltage and current from the system.

shaded place or install a shed to protect the inverter from direct sunlight, rain and snow etc. PROTECT the LCD screen
from excessive UV exposure
d. The inverter should be installed upright on a vertical surface.
3.2.2 Installing the inverter
The inverter is wall-mounted type, should be installed on a vertical, solid mounting surface, such as wood studs,
brick or concrete wall. Two or more persons may be needed to install the inverter due to its weight. The slots on
mounting bracket can accommodate various stud spacing from 12inch to 16inch.

Step1. Mark the positions of drill holes with the mounting bracket, then drill 4 holes of 8mm(5/16inch) diameter
and make sure the depth of the holes is deeper than 50mm(2inch).
Step3. Hang the inverter onto the wall-mounting bracket and lock the inverter on the wall using 2 self-tapping
screws on the top of the inverter.
Step2. Install the expansion bolts into the holes and tighten them, then use the corresponding nuts and
washers (packaged together with the expansion bolts) to install and fix the wall-mounting bracket on the wall.

* Please check the lowest ambient temperature of the location of the installation. The rated
Voc on solar panel nameplate is obtained at 25 temperature. Solar panel Voc will increase
with the decreasing of ambient temperature. Please ensure the Max.solar string voltage
corrected at the lowest temperature not exceed the inverter max input voltage 550V for safe.
PV connection of this hybrid inverter is same as traditional on-grid solar inverter (string inverter).

1. The inverters has triple MPPTs. For MPPT1, users can connect two strings. For MPPT2 and
MPPT3, users can connect one string.
2. When users connect 2 strings to MPPT1, make sure the two strings has same quantity of
solar panels. The inverter will limit the total MPPT1/MPPT2/MPPT3 input current to
25A/15A/15A automatically.
3. The inverter will limit the max solar input power to 18kW totally.

Steps for PV connection
d. Route the PV conductors through the
conduit and conduit fitting into the inverter.
a. Strip off 1/4-5/16inch(6~8mm) insulation
on the PV string positive and negative
conductors.
b. Use wire ferrules for PV string conductors
if they are stranded wire type.
c. Insert the conduit fitting to the opening
for PV connection and tighten it from inside
using the counter nut.
e. Secure the cable gland in place.
f. Ensure that the cables are connected
correctly and securely. Then take appropriate
measures to ensure that the conduit and conduit
fittings are fastened reliably, and seal the cable
entry holes.

Step 1: Strip 1/4-5/16inch(6-8mm) insulation from the cable end and crimp OT rings for the cable ends.
Step 3: Secure the conduit fitting to the enclosure using the counter nut.

Step 2: Route the battery power cable through the cable gland, connect positive to BAT+,negative to BAT-.
Step 5: Fix the cable gland in place.
Step 4: Fasten the OT rings of battery positive and negative cables to the lugs according to the marking.
Polarity reverse will damage the inverter!
Install a DC isolator between battery and
inverter can avoid potential damages
caused by electric arc.
3.5.2 Battery communication cable connection
A correct battery communication cable must be used to connect the battery to the inverter when users
choose lithium-ion battery type. Please select ‘Lead-acid ‘ type if the lithium battery can not communicate
with inverter. The battery communication port on inverter is a RJ45 socket, Pin for the RJ45 plug of the
communication cable is as below. Make the communication cable according to the below inverter Pin and
the correct pinout of communication port on battery. The inverter supports both CAN and
RS485 communication.

1. Please make sure the lithium-ion
battery to be used is compatible with
inverters. Please contact
your
distributor for updated battery
compatible list.
2. If you are using multiple battery
modules with the inverter, the inverter
communication cable must be
connected to the master battery. Please
check with your battery supplier for
battery master and slave settings.
1. The temperature sensor for lead
-acid battery is optional. If you need
it, please contact distributor for
purchasing.
For Li-ion battery
For Lead-acid battery
2. There are three stages for lead-acid
battery charging. For charging/discharge
related parameters, please check charge
/discharge setting page.
3.6 Grid&EPS load Connection
3.6.1 Grid type selection
The inverter can be used with 120/240V split-phase , 120/208V split-phase , and 240V single phase service.
You can choose the grid type on LCD. If you are going to use the inverter with 240V single phase supply, please
contact your supplier for the correct connection diagram.
The inverter has passed the main grid-connection regulations in the US(IEEE1547, CA Rule21, HECO Rule 14H,
etc.). Users can choose different Grid Type in Advanced program as below:

3.6.2 Grid and EPS load connection for split-phase service
Connection diagram for 120/240V is as below. The connection diagram for 120/208V split phase service is
roughly the same except that generator is not supported.
The inverter can be connected to the load side of the service disconnecting means if the busbar rating in the
main panel can meet the NEC705.12(B)(3) requirements. Otherwise, a Line side connection can be made to
avoid an expensive main panel upgrade.

f. Checks that the cables are connected correctly and securely, then take appropriate measures to ensure
that the conduit and conduit fitting are secured reliably, and seal the cable entry holes.
To measure the power import from and export to the grid, a pair of CTs or one triphase meter must be
installed at the service entry point in or near the main service panel. We standard supply 2 CT for one
inverter.
The CT interface for 2 CTs connection is a RJ45 port ,we have made a RJ45 plug on those 2 CTs in advance,
so you can connect it to port directly.

The Luxpower inverters support two ratios of CT clamp- 1000:1 and 3000:1 . The CT ratio of the CTs in
the accessory bag is 3000:1. If you are using a 3rd party CT, please ensure the CT ratio is either 1000:1
or 3000:1, and then select the correct CT ratio setting in the inverter monitor page or on inverter LCD.
CT Clamp Ratio
The CT wires can be extended with a common ethernet cable if the length is not enough. A RJ45 adapter
is needed for the extending. The CT wires can be extended up to 300ft(around 100m).
