  • Page 8: Pv Wiring Instructions

    FOR ALL MODULES, THE CALCULATIONS NEED TO BE PERFORMED OR VERIFIED BY USING A STRING CALCULATOR AND CONSULTING A PROFESSIONAL. 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 25ºC and the temperature coefficients for voltage and power.

  • Page 9: Battery Connection

    Please see the diagram below for PV terminal labeling. 3.2 BATTERY CONNECTION The EG4 12kPV can utilize either lithium or lead-acid batteries. There is a combination of settings that need to be changed depending on the battery type. (See the battery user manual for more information.)

    3.3.1 STEPS FOR AC CONNECTION Please follow the steps outlined below to ensure proper AC Input/Output connections. Step 1: Before installation of any wiring, please 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. Step 2: Strip off 5/16-3/8 in.

  • Page 13: Current Transformer (Ct) Connection

    3.3.2 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.
