EES (Enphase Energy System) 3.0 installer certification training featuring the IQ Battery 5P practice test with actual possible questions and answers True or false: In a solar array with Enphase microinverters, all of the solar panels should have the same orientation for maximum energy production. -Ans: False The energy production of each micro/panel is independent from the others Which of the following are features of Enphase Enlighten monitoring? -Ans: E. All of the above Which government agency recommends the use of microinverters for solar PV installation in hurricane-prone areas? -Ans: C. FEMA- Federal Emergency Management Agency If one microinverter in a solar PV system fails, what will occur? -Ans: B. The one solar panel connected to that microinverter will be out of operation What is a single point of failure? -Ans: A. A part of a system that, if it fails, will stop the entire system from working The "ABC's" of Fall Protection stands for -Ans: Anchor, Body Harness, Connector What governing body sets federal and statewide safety standards? -Ans: A. OSHA How many points of contact must you keep on a ladder to be considered safe? -Ans: B. 3 How often should you check your fall protection equipment? -Ans: C. Before each use True or false: Fall protection can save your life. -Ans: True What are the 3 core components of an Enphase PV system? -Ans: Enlighten, Envoy, Microinverter What is the ratio between microinverters and PV modules in an Enphase PV system? -Ans: 1:1 What are the maximum number of circuits that can be installed in an Enphase Combiner 3? -Ans: 4 What device collects data from the array and uploads that data to the web? -Ans: B. Envoy True or false: Solar panels make DC energy -Ans: True True or false: Enphase microinverters do not need an EGC. – Ans: True IQ 7+ Inverters are compatible with modules with what cell counts? Select two answers. Ans: C. 60 D. 72 How many models of inverters are currently in the IQ7 line? -Ans: 4; The 7, 7+, 7A, & 7X True or false: Enphase microinverters convert DC electricity to AC electricity. -Ans: True Enphase Q cable has 2 conductors in it. What size are those conductors? -Ans: D. #12 AWG True or false: Enphase Q Raw cable allows you to make jumpers between two arrays. -Ans: True Enphase's disconnecting tool allows you to -Ans: D. All of the above True or false: A terminator cap is required on all exposed, cut Q cable ends. -Ans: True True or false: Terminator caps make cut Q Cable ends safe and waterproof. -Ans: True What communication protocol does the Envoy use to communicate with the microinverters? -Ans: A. Powerline communications (PLC) True or false: The IQ envoy is both a monitoring and a control device. -Ans: True The IQ Envoy is able to communicate with: -Ans: D. All of the above The IQ Combiner 3 and 3C: -Ans: D. All of the above True or false: The combiner 3 has a built in Envoy. -Ans: True The Enphase Q cable plugs into . -Ans: B. Enphase microinverters Enphase Q Raw cable has what size conductors in it? -Ans: B. #12 AWG Where do you go to find data on a system you have built? -Ans: B. Enlighten True or false: Enphase Q Cable works with other manufacturers' equipment. -Ans: False What impact does temperature have on solar panels? -Ans: Do solar panels deliver a constant STC rated output when installed at most homes or businesses? -Ans: C. No, solar panels typically are warmer and have less light reaching them than in the STC factory test conditions When designing solar systems, selecting the right microinverter and solar panel pairing based on power output requires analysis. Which of the following statements is the most accurate? -Ans: UNSURE, but it's either B. To claim STCs the output of each microinverter can be no less than 75% of the output of the solar panel that it is connected to OR C. Selecting solar modules with power output lower than the inverter output is a good idea because all solar panel output will always get captured What factor(s) primarily impact the maximum quantity of microinverters per AC branch circuit? -Ans: B. Conductor size (12 AWG) enclosed in the Q cable What is the maximum circuit breaker current size allowed for each PV AC branch circuit using a 1 phase Q relay in single phase installations? -Ans: A. 20 AMP What is the maximum circuit breaker current size allowed for each PV AC branch circuit using multiphase phase Q relay and 3phase Q wiring in a multiphase installation? -Ans: C. 25 AMP Enphase recommends that from the point of supply to the AC isolator, PV system designs
