3. INVERTER SAFETY SAFETY INSTRUCTIONS International safety regulations have been strictly observed in the design and testing of the inverter. Before beginning any work, carefully read all safety instructions, and always observe them when working on or with the inverter. The installation must follow all applicable national or local standards and regulations.
Page 9 WARNING: TO REDUCE THE RISK OF INJURY, READ ALL INSTRUCTIONS! All work on this product (system design, installation, operation, setting, configuration, and maintenance) must be carried out by qualified personnel. To reduce the risk of electric shock, do not perform any servicing other than those specified in the operating instructions unless qualified to do so.
Page 10: Brief Introduction
4. BRIEF INTRODUCTION The EG4 12000XP is a 12kW 120/240VAC split-phase, all-in-one, off-grid, sine wave inverter with grid ® charge capability designed for the residential and small commercial markets. The 12000XP can receive 28kWs of DC (STC) solar PV on two 35A MPPTs and generate 12000 watts of power and can feed through 24000 watts (100A) of utility or 90A of generator split phase 120/240VAC power.

Page 14: Storing The Inverter
5.2 STORING THE INVERTER If placing the inverter into storage before installation, keep the following factors in mind while selecting a storage location. CAUTION: • The inverter and its components must be stored in its original packaging. • The storage temperature should be within -13 – 140°F (-25 – 60°C) and humidity within 0 –...
Page 15: Location Selection And Installation
5.3 LOCATION SELECTION AND INSTALLATION • The mounting wall should be strong enough to bear the weight of the inverter. • Maintain the minimum clearances presented below for adequate heat dissipation. • Install the inverter upright on a vertical surface. 5.4 MOUNTING THE INVERTER The inverter is designed to be vertically wall-mounted on a solid, non-combustible material such as brick or concrete.
Page 16 NOTE: • Ensure the surface the inverter is being mounted to can support the weight of the unit and has proper spacing as per the diagram above. • The screws needed for attaching the bracket to studs are NOT included in the packing contents and must be provided by the installer.
Page 17 6. Temporarily mount the right-angle bracket to the side of the inverter (located at the bottom, one on each side). Mark a hole on the wall based on the hole location inside the right-angle bracket. (Repeat this step for both sides) 7.
Page 18: Cable Connections
6. CABLE CONNECTIONS To expose the cable box area, remove the bottom cover by removing the 4 screws identified in the image below. Once the cover is removed, follow the sections below for connecting the wiring for PV, AC, Battery, Generator, RSD, and Parallel cables. Before connecting any wiring to the inverter, verify each wire is not carrying voltage using a multimeter.
Page 19 CAUTION The array may have a higher Imp than the 35A specified, but the MPPTs will not make full use of the extra current and may lead to internal component deterioration over time. String Sizing When solar modules are put in a series string, the voltage multiplies by the number of modules and the amperage stays the same as the rating of each module.
Page 20: Battery
6.2 BATTERY The EG4 12000XP supports connecting to lithium or lead-acid batteries. There is a combination of ® settings that need to be configured depending on the battery type installed. When using lithium batteries, it is recommended to configure the battery to communicate with the inverter using the included battery communications cable.
Page 21: Ac Connections
NOTE When installing multiple inverters in parallel, the battery or battery bank must be connected to each inverter so the current can be evenly shared to each inverter. The positive cable from the battery or battery bank to each inverter should be of equal length.
Page 22 CAUTION • Do not misconnect the grid input and loads output connections, which could cause damage to the inverter and attached devices. • Be sure to connect AC wires with correct phasing. If L and N wires are connected in reverse, it may cause a utility short circuit when the inverters are working in parallel operation.
Page 23: Neutral-Ground Bonding
Cable Installation 1. Before making any connections, ensure all breakers are open (off). Use a multimeter to confirm the AC input lines (L1, L2 and neutral) are not carrying current from the main panel. Verify the DC input lines are not carrying current. Verify the PV input lines are not carrying current.
Page 24 Cable Installation: 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. 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 or bare.
Page 25: Off-Grid
6.6 OFF-GRID The EG4 12000XP inverter can fully function in off-grid 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 (>15kW per 12000XP).
Page 26: Ac Coupling Connections
6.7 AC COUPLING CONNECTIONS AC coupling allows the user to add onto an existing grid tied solar system. PV comes from the existing system while the AC coupled inverter controls battery charging and any extra PV coming into the system. This setting allows the user to still have power off-grid. The inverter can accept PV inputs to both MPPT channels and AC coupled solar input simultaneously.
Page 27: Single Inverter
7.1 SINGLE INVERTER 1. Ensure each inverter circuit breaker is in the open (OFF) position. No voltage should be coming in or out of the inverter at this point. 2. Using a multimeter, check the following: a. Check the battery bank voltage is within operating range at the inverter DC breaker, or the external DC disconnect.

Page 29 In order to support proper ventilation and cooling, the inverters are installed with required • clearances as shown in section 5. CAUTION: Only use the provided parallel cable when connecting the inverters together. Using the wrong cable could cause hardware damage. If a longer cable is required, see below for more information on creating a cable or contact the distributor.
Page 30 10. Move the external PV isolator switch to the closed (ON) position (if equipped). Set the PV switch on the side of the inverter to the closed (ON) position. 11. If using AC input, set the external breaker between input panel and inverter to the closed (ON) position.
Page 31 Set System Type: Change from Not Parallel to Parallel. Battery Shared: Place a check mark in the battery shared box. Note: Repeat the “Set System Type” and “Battery Shared” settings on each inverter connected in a parallel configuration. The rest of the settings will be copied to each inverter as they are set on the master inverter.
Page 32: Rapid Shutdown / Ess Disconnect
8. RAPID SHUTDOWN / ESS DISCONNECT The inverter includes a rapid shutdown system that complies with 2017 and 2020 NEC 690.12 requirements. A rapid shutdown switch should be connected to the RSD terminals on the master inverter and mounted in a readily accessible location outdoors (check with the local AHJ for specific requirements).
Page 33: Front Panel Display
9. FRONT PANEL DISPLAY Navigation The user can wake up the LCD screen by simply Buttons pressing the Enter button.
