4.3 CONNECTION OVERVIEW
4.3.1 SYSTEM CONNECTIONS
Before connecting any wiring, please remove the bottom cover by removing the 7 screws as shown
below.
4.4 PV CONNECTION
4.4.1 CONNECTING PV TO THE INVERTER
Install a separate DC circuit breaker/isolator between the inverter and PV module(s). The
recommended DC breaker is a 4-pole 600V/20A. The minimum isolator to house both positives and
both negatives if using two independent strings. If only using 1 string, a 2 pole 600V/20A
isolator/breaker is recommended. The recommended cable size for the PV connection(s) is 10 AWG
(4mm2) torqued to 1.2 Nm.
Consult with your installer to ensure that appropriate cable sizing is used due to various factors such as
voltage drop and Voc.

Reminder!
Verify the lowest ambient temperature of the installation location. The rated Voc on the solar module
nameplate is obtained at STC (77°F/25°C). As the ambient temperature drops, the solar module Voc
increases. Please ensure the maximum solar string voltage, corrected at the lowest temperature, does
not exceed the inverter’s maximum input voltage of 480VDC.
PV Input Data Description

Load Output Minimum Voltage Minimum voltage needed to output power on Load side >140 VDC
MPP Operating Voltage Range Range where the MPPT can track 120–385 VDC
Nominal MPPT Voltage The MPPT will operate most optimally at this voltage 320 VDC
Nominal MPPT Amperage The MPPT will operate most optimally at this amperage 17A
Maximum MPPT Amperage The MPPT can accept up to this amperage (clipping will
occur past this value)
25A
Maximum Utilized Solar Power

power loss factors
8kW
4.4.2 STRING SIZING
When solar modules are put in a series string, the voltage multiplies times the number of
modules and the amperage stays the same as each module.
For example: Using solar modules that have a 40VDC Voc (@77ºF) with a Max Power
amperage of 10 Amps (Imp) - 10 modules wired in a series string would have a Voc of 400
VDC (@77ºF) and a string amperage of 10 Amps. When the temperature lowers, the voltage
can rise above the maximum allowed by the inverter and damage will result.
CAUTION: To determine how many modules you can have per string; first verify the lowest
possible ambient temperature of the installation location. Next, find the rated Voc, Vmp, Isc and
Imp of the solar module at 77ºF and the temperature coefficients for voltage and power. Then
calculate highest possible Voc for the entire string when the ambient temperature falls to the
lowest possible ambient temperature upon sunrise. To make this calculation, use a string
calculator or consult your solar designer or solar electrician.
DANGER!
Damage WILL Occur if the string voltage exceeds the inverter’s maximum input
voltage of 480VDC!
Finally, calculate the maximum current of the string (Isc) so as not to exceed the Inverter’s
MPPT circuit ratings of 25A (see note at end of section). Double check if the calculated Vmp
range is within the 120-385 VDC optimal MPPT circuit operating range. It is recommended to
consult a solar designer for assistance.
FOR ALL MODULES, THE CALCULATIONS NEED TO BE PERFORMED OR VERIFIED BY
USING A STRING CALCULATOR OR CONSULTING A PROFESSIONAL.
The inverter has two MPPT PV charging circuits. MPPT #1 and #2 will utilize up to 17 amps, which
means two strings can be paralleled for any modules having less than 8.5A (Imp) rating.

11
When sizing strings for each MPPT, they MUST be the same model, brand and # per string
(series and parallel).
All panels on a series/parallel string should face the same orientation and be exposed to
roughly the same shading across the string. Consideration should be placed on string location
and wiring order on the racking to minimize shading effects. One shaded module can
disproportionately reduce output for the entire string so avoiding linear strings in favor of
rectangular strings can increase output. Optimizers can also achieve this.
Note: The array may have a higher Imp than the 17A specified, but the MPPTs may not make
full use of the extra current and may lead to component deterioration over time.
4.4.3 PV WIRING INSTRUCTIONS
Please follow the steps listed below to ensure proper PV connections.
Step 1: Before installing PV wiring into the inverter, please ensure all breakers and disconnects are
open (off) and confirm your PV strings are not energized by using a multimeter to ensure there is no DC
voltage on the lines. Once that has been verified, please proceed to step 2.
Step 2: Strip off 1/4 - 5/16 in. (6 – 8mm) insulation from the PV strings’ positive and negative
conductors
Note: If using fine stranded wire, use ferrules to secure the connections to the inverter.
Step 3: Insert the conduit fitting into the openings for the PV connections and tighten from the inside
using the counter nut.
Step 4: Route the PV conductors through the conduit fitting and into the inverter.
Step 5: Secure the PV conductors in place into their respective terminals and torqued to 1.2Nm. Verify
the cables are secure by lightly tugging on them.
Step 6: Ensure the conduit and conduit fittings are fastened reliably, and the cable entry holes are
sealed.
Note: All exposed metal parts of the system must be grounded regardless of voltage, including solar
panel frames.
DO NOT GROUND NEGATIVE PV LINES, ONLY SOLAR PANEL FRAMES.

4.5.2 LITHIUM BATTERY COMMUNICATIONS
Upon successful installation of your batteries, follow the next steps to enable closed-loop
communications (with compatible battery modules) between batteries and inverter.
1. Connect either the CAN or RS485 (depending on make/model of battery) communications cable
between inverter and battery. See diagram below.
2. For the inverter to communicate with the battery BMS, you must change setting 3 to “Li-ion”.
The inverter will then switch to a secondary setting. Here, you select your make/model of battery
and press enter to register the change. For EG4 batteries, you would select “0” after confirming
“Li-ion” as the battery type.
Note: If needing to extend your inverter to battery communication cable or create your own, please

Ground-Neutral Bonding
The information below describes the nature of the ground and neutral in the inverter and
their relationship to the system. Always consult with your installer or a licensed electrician to
ensure that the right configuration is being used:
•The neutral line is a solid connection between AC input and AC output (known as
a Common Neutral Architecture).
•The neutral line between the AC input and AC output is never disconnected.

14
•This architecture assumes there is a single neutral-ground bond in the system. Typically, the
neutral-ground bond for a system will be at the first means of disconnect for the grid. However, if
there is no neutral-ground bond in the system, the 6000XP can be configured to create the bond
internally (see setting 26).
Note:This is not a dynamic bond. It is always enabled or always disabled.
4.6.1 STEPS FOR AC CONNECTION
Please follow the steps outlined below to ensure proper AC Input/Output connections.
Note: Always be sure to connect your AC Output ground wire to the Ground terminal bus (labelled PE
in the diagram) first before installing your AC Outputs L1 and L2.
Step 1: Before installation of any wiring, please ensure all breakers are open (off) before making any
connections. Use a multimeter to confirm your AC Input lines (L1, L2 and neutral) are not energized.
Step 2: Strip off 5/16-3/8 in. (8-10
mm) insulation from the AC cables.
Note: If using fine stranded wire, use
ferrules to secure the connection.
Step 3: Fasten the AC Input wires
into their respective terminals using
the proper torque.
Reminder!
After connecting all AC wiring, put the built-in LOAD breaker back to the ON position before
providing power to the load.
4.7 WORKING WITH A GENERATOR
4.7.1 GENERATOR SYSTEM CONNECTION
The EG4 6000XP can utilize a generator for backup power in the case of Grid failure. When sizing
generators to provide both adequate power and frequency, keep in mind that the THD (Total Harmonic
Distortion) of the generator must be <3%. It is a good rule of thumb to size your generator for at least
1.5x the output of the inverter to allow for powering loads and charging batteries. The table listed below
shows the recommended generator capacity for optimal operations.
Number of Inverters in Parallel
Generator Capacity
1
>10kW
2
>15kW
3
>20kW
4
>25kW
When properly wired and configured, the generator, if compatible with remote start, will start automatically
when the battery voltage/SOC is lower than the cut-off value or there is a charge request from the BMS.
When the generator is running, it will charge the batteries and excess AC power will be diverted to the
Standard US Wiring:
L1 – Black
L2 – Red
Neutral – White
Ground – Green

15
AC output (LOAD) to power loads. The pass-through relay on the inverter Generator terminal (GEN) is
30A. When the generator is on, please ensure the total load and charge current does not exceed 30A.
4.7.2 INTEGRATED DRY CONTACTS
This inverter has two dry contact connections that can be used to remotely enable external
devices such as a generator. The Dry Port (NO2, COM2) can be used to remotely enable an
external device when the battery voltage reaches a pre-set warning level. Similarly, the GEN
Port (NO1, COM1) can be used to remotely start a generator. To do so, the generator start
signal must be connected to the inverter GEN contacts, NO1 and COM1. The following table
shows the dry contact status under various system conditions.
4.7.3 GENERATOR AC CONNECTIONS
Please follow the steps listed below to ensure your Generator connections are installed correctly.
Note: If running more than one inverter in the system, you must wire the generator to provide power to
every inverter running in parallel for the inverters to function as intended.
Step 1: Before making any wiring connections, be sure to have the inverter(s) powered off, the
generator powered off, and all circuit breakers open (off) to prevent damage to the unit.
Step 2: Properly identify the generator’s output lines. By US wiring standards, L1 wire will be black, L2
will be red, Neutral will be white, and ground will be green. Once identified, remove ≈10mm from the
insulation sleeve on the wires.
Step 3: Ground the generator’s output ground to the Ground Bus (labelled PE) of the inverter.

Step 4: Install L1 to the GEN port’s L1 terminal, then install L2 to the GEN port’s L2 terminal. Next,
fasten the Neutral wire from your generator into the N-BUS (Neutral Bus).
4.8 GENERATOR START AND STOP SETTINGS
Using the EG4 Monitoring Software, go to the “Maintenance” page where “Remote Set” will
be selected automatically. Scroll down to the “Generator Charge”’ section and select the
“Generator Charge Type” (see screenshot below). Normally, lead-acid batteries are charged
according to voltage and Lithium batteries are charged according to SOC.
Generator Start Conditions:
The generator will start when utility fails and one of the following conditions is met:
-The battery is discharged to the cut-off setting or
-There is a force charge request from battery or
-The battery voltage or SOC is lower than the “Generator Charge Start Battery
Volt/SOC” setting
Generator Stop Conditions:
When battery voltage or SOC is higher than the “Generator Charge End Battery Volt/SOC”
settings.
4.9 OFF-GRID
The 6000XP Inverter can fully function in Off-Grid only mode. It does not need the
utility or generator to function. Purely off-grid systems that do not have access to
the utility should strongly consider having a 2-wire start backup generator for
extended cloudy periods (8-12 kW diesel recommended per 6000XP - 8kWs
minimum per inverter). Off-Grid systems should have robust battery banks sized to
ensure multiple days of power and to reduce generator run time.
4.9.1 OFF-GRID WIRING
The 6000XP can accept up to 60 Amps (14.4kWs) of generator power and will pass
through all available power to the loads. Therefore, the Loads subpanel can be
sized up to the size of the backup generator with 60 Amp minimum per inverter.

17
4.10 PARALLELING INFORMATION
4.10.1 PARALLEL COMMUNICATION CONNECTIONS
The EG4 6000XP inverter supports parallel connections to expand power and energy capacity to suit
different usage scenarios. Up to 16 units can be paralleled to reach a capacity of up to 96kW. The
parallel communication wiring diagrams are shown below. The manual bypass switch connects the
loads to LOAD panel as default. If the inverters fail, users can switch the loads to utility.
Remember!
Put the CAN communication PIN to ON status for the first and the last inverter and OFF for
inverters in between.
Note: Both switches in the “ON” position translates to address 1. Both switches in the “OFF” position
translates to address 0.
Please contact your inverter supplier for more detailed guidance on paralleling systems.
4.10.2 PARALLEL CONFIGURATION
Important notices for parallel system:
•If utilizing the Generator input (GEN), ensure that the generator is connected to all inverters in
parallel.
•If not possible to evenly divide solar strings per inverter, it is recommended to have more PV
strings on the master inverter.
•The values shown on the LCD of each inverter displays the individual inverter’s contribution to
the system, not the system’s total.
Before commissioning:
1. Verify that all inverters in the system are updated to the latest firmware. Please contact your
distributor to confirm you have the latest version.
2. Make sure the power cables and parallel communications cables have been wired correctly, and
verify the DIP-switch settings are correct.
3. Ensure your LOAD breakers are off (open). Ensure there is no AC voltage present with a
multimeter before proceeding to the next step.
4. Power on the inverters.
5. Navigate to setting 21 to configure phasing.
6. Starting with the inverter with battery to inverter communication cable connected, change setting
21 to 1PH for split-phase parallel. The LCD will then switch to a secondary setting, Parallel
Phase. Set the inverter to P1 for phase 1. Repeat this step for all paralleled inverters.
7. Enable “Battery Shared” on all inverters in parallel.
