    2. INVERTER SAFETY 2.1 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.

    3. PV CONNECTION 3.1 CONNECTING PV TO THE INVERTER CAUTION: Consult with an installer to ensure that appropriate cable sizing is used; due to various factors such as voltage drop and VOC. PV CABLE SIZE MINIMUM INSULATOR VOLTAGE 10 AWG – 6 AWG (Max) (6 mm –...

  • Page 8: Pv Wiring Instructions

    CAUTION: To determine how many modules are ideal 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 25°C and the temperature coefficients for voltage and power.
  • Page 9 See the diagram below for PV terminal labeling.

  • Page 10: Battery Connection

    4. BATTERY CONNECTION The EG4 12kPV can utilize either lithium or lead-acid batteries. For each battery type, there is a ® specific combination of settings (See the battery user manual for more information). 4.1 BATTERY CABLE CONNECTION Follow the steps below to properly connect the battery cables: 1.

  • Page 11: Lithium Battery Communications

    4.2 LITHIUM BATTERY COMMUNICATIONS Upon successful installation of the 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 master battery. See diagram below. 2.

  • Page 12: Steps For Ac Connection

    5.1 STEPS FOR AC CONNECTION Follow the steps outlined below to ensure proper AC Input/Output connections: 1. Before installation of any wiring, ensure all breakers are open (off) before making any connections. Use a multimeter to confirm the AC Input lines (L1, L2 and neutral) are not energized.

  • Page 13: Current Transformer (Ct) Connection

    5.2 CURRENT TRANSFORMER (CT) CONNECTION To measure the power imported from and exported to the grid, a pair of CTs or one three-phase meter must be installed at the service entry point in or near the main service panel. Two CTs are provided with each inverter.
  • Page 14 Line 1 - Black Line 2 – Red Neutral – White (Grey in image) CT Comms Cable - Blue Once the CTs are clamped on the AC Input Lines, connect the CT communications cable (RJ45) to the port on the inverter. NOTE The CTs must be installed in or near the Main Service Panel for accurate readings.

  • Page 15: Off-Grid Connection

    5.3 OFF-GRID CONNECTION The 12kPV can function fully in off-grid only mode, eliminating the need for utility or a generator. It is highly recommended that purely off-grid systems without access to the utility have a backup generator with remote start for extended cloudy periods (minimum 5kW diesel generator per 12kPV inverter).

  • Page 16: Dry Contact Information (Gen Port)

    6.2 DRY CONTACT INFORMATION (GEN PORT) This inverter has a dry contact connection that can be used to remotely enable external devices such as a generator. The GEN contacts (NO1, CO1) 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 CO1.

  • Page 17: Generator Ac Connections

    6.3 GENERATOR AC CONNECTIONS NOTE If running more than one inverter in the system, the generator must be wired to provide power to EVERY inverter running in parallel for the inverters to function as intended. Follow the steps listed below to ensure the generator connections are installed correctly: 1.

  • Page 18: Generator Start And Stop Settings

    6.4 GENERATOR START AND STOP SETTINGS Using the EG4 Monitoring Center, go to the “Maintenance” page, where “Remote Set” will be ® selected automatically. In the “Model” section in “Common Setting”, select the “Battery Type” (see image below). Normally, lead-acid batteries are charged according to voltage and lithium batteries are charged according to SOC.

  • Page 19: Paralleling Information

    7. PARALLELING INFORMATION PARALLEL COMMUNICATION CONNECTIONS Multiple 12kPVs can be paralleled to expand energy storage and backup capacity to suit different scenarios. Up to 10 units can be paralleled to reach a load capacity of up to 80kW. The parallel communication wiring diagrams are shown below.
  • Page 20 REMINDER: If needing to extend the inverter-to-inverter paralleling cable, ensure the cable is a straight-through CAT5 and up cable. See image below for reference. Before commissioning: 1. Verify that all inverters in the system are updated to the latest firmware. Contact the distributor to confirm the latest version.
