EG4 Electronics EG4 Electronics www.eg4electronics.com www.eg4electronics.com Before connecting all wirings, please take off bottom cover by removing the five screws. When removing the bottom cover, be carefully to remove three cables as shown below. Mounting the Inverter Consider the following points before selecting an install location: Do not mount the inverter on flammable materials.
EG4 Electronics EG4 Electronics www.eg4electronics.com www.eg4electronics.com Battery Connection CAUTION: For safe operation and regulation compliance, DC overcurrent protection and means of disconnect should be installed between the battery and inverter. In many cases individual battery units will come with breakers, however overcurrent and disconnecting means should be added for banks of multiple batteries.
EG4 Electronics www.eg4electronics.com BMS Communication Installation- EG4-LL 1. Introduction When connecting to LFP battery, it is recommended to purchase a custom-made RJ45 communication cable. Please check with your dealer or integrator for details. This custom-made RJ45 communication cable delivers information and signal between lithium battery and the inverter.
EG4 Electronics www.eg4electronics.com Battery Networking- EG4-LL Using the 1ft RS485 cable interconnect your batteries as illustrated in the diagram below.

Page 16
NOTE: For EG4-LL ensure the red power switch is set to "ON" as well as the breaker. NOTE: Even with the EG4 batteries having built-in breakers, a minimum 150A in line breaker is required, and a 200A in line breaker is recommended.
EG4 Electronics www.eg4electronics.com AC Input/Output Connections CAUTION!! Install a breaker at the source of the AC input power source per requirements of authority having jurisdiction. Ensure the AC source circuit is properly rated for the inverter/charger load specification. CAUTION!! There are two terminal blocks with “IN” and “OUT” markings. Do NOT reverse the input and output connections.

EG4 Electronics www.eg4electronics.com 5. Connect the AC output wires according to labels printed on the case above the terminal blocks. Connect the ground wire first ( Ground (Green or Green with Yellow stripe) L→LINE (Black for Line 1)(Red for Line 2 in 120/240 split-phase configuration) N→Neutral (White or Gray)
EG4 Electronics www.eg4electronics.com PV Connections CAUTION: Before connecting PV modules/strings, install separate DC circuit breakers or a means of disconnect paired with properly sized fuses between inverter and PV array/s. DO NOT work with or connect live PV conductors to the unit. Ensure all exposed conductors are safely disconnected from the power source.
