Enphase Energy inverter is attached to the back of each 250W solar panel which allows each panel to operate independent of each other. Enphase was one of the original inverter manufactures to create a panel level inverter that is fast, easy, safe to install and essentially plug-n-play. The microinverter is attached to the back of each solar panel which allows each panel to operate independent of each other. Each microinverter provides individual maximum power point tracking at the panel level. This advantage significantly reduces planning and performance obstacles such as shading issues or panels on different planes. If no such conditions exists, then the advantage over a central inverter does not exist. Each of the microinverters that makes up the kit integrates with optional Emphases network technology allowing you to monitor each panels performance throughout the day which is a very cool feature if you are a techie. Install an NEMA3 combiner box at a suitable location on the solar racking system. You can center feed the branch, or you can install the combiner box at the end of a row of solar panels. Provide an AC connection from the AC combiner box back to the electrical utility connection using equipment and practices as required by the NEC and your local jurisdiction.
Each of the microinverters that makes up the 4500W solar kit integrates with Enphase network technology allowing you to monitor each panel performance throughout the day. (Monitor is Optional) Enphase system monitoring capability be accomplished using the optional Envoy monitor by simply plugging into a 120 volt wall outlet. You can also track your solar production by using other different types of monitors, but most customers would opt for the Envoy monitor because you can read individual panel performance rather that the whole systems performance.
Because you do not use a DC combiner with breakers, the cost of the microinverter VS a central inverter is offset somewhat. Finally a home solar package that matches the 25 year guarantee on the solar panels with a 25 year guarantee on the inverter. Blue Pacific Solar has done all the work for you with this efficient simple grid-tied home solar system. Following our line drawings you will end up with an NEC (National Electric Code) compliant home solar system with a life expectancy of well over 25 years.

*STC - To learn more about solar panels and how they are measured you need to know what STC stands for. STC in an acronym for "Standard Test Conditions". All solar panels are rated in Watts. The watt rating is how much power (amps times volts) the panel will produce in full sunlight at 25 degrees C (77F). This is the industry standard (STC) for all PV panel ratings (PV means Photovoltaics which is a fancy word for solar). Solar panel manufactures have long used this test standard which is 1,000 watts per square meter solar irradiance, 1.5 Air Mass and a 25 degrees C. cell temperature.
PTC is an acronym for "PV-USA". The PV-USA test conditions was developed at the PV USA test site at the University of Davis, California for standards established by the California Energy Commission that are considered closer to real world conditions (Real World Vs STC factory test conditions). The PTC rating test is 1,000 watts per square meter solar irradiance, 1.5 Air Mass, and 20 degrees C. ambient temperature at 10 meters above ground level and wind speed of 1 meter per second. In California, solar panels manufactures must be tested and rated independently at the PV USA test facility at the University of Davis (CA) to be considered for rebates.
The ambient temperature rating (PTC) is generally considered a better real world standard than factory conditions because silicon solar cells average about 20 degrees C. above ambient temperature in the real world, cell voltage drops as temperature increases. A module's power output in real life conditions is lower than the power measured at the panel manufacturing factory where cell temperature is maintained at a controlled 77 degrees F. (25 C).
STC Vs PTC Cell voltage drops about 0.08 volts per degree C. in environments which exceed 25 degrees C. That means an STC rating of 17 volts can actually become a PTC (PV-USA) rating of 15 or 16 volts. Using Ohm's Law, volts times amps is equal to watts which equals power, so a reduced voltage, means reduced watts.
Neither PTC nor STC account for all "real-world" losses. Actual solar systems will produce lower outputs due to soiling, shading, module mismatch, wire losses, inverter and transformer losses, shortfalls in actual nameplate ratings, panel degradation over time, and high-temperature losses for arrays mounted close to or integrated within a roofline.

Enphase Energy 4500W Gridtie System Do-It-Yourself Home Solar System
Enphase Energy 4500W Solar Package; The Enphase system maximizes energy production from your array using some very simple principles. Each Enphase microinverter is individually connected to one solar panel in your array. This unique configuration means that an individual Maximum Peak Power Point Tracker (MPPT) controls each solar panel. This ensures that the maximum power available from each solar panel is exported to the utility grid regardless of the performance of the other solar panel in the array. That is, although individual 245 watt solar panels in the array may be affected by shading, soiling, orientation, or solar panel mismatch, the Enphase microinverter ensures top performance for each panel. The result is maximum energy production from your solar array.
Our 4500W kit is relatively simple to layout and install. You will not need string calculations, just keep your string to a maximum of 17 245 watt panels, and you can install individual solar panels in any combination of solar panel quantity, type, age and orientation. Each microinverter quickly mounts on the roof or ground rack (optional), directly beneath each solar panel. Low voltage DC wires connect from the solar panel via waterproof MC4 connectors directly to the co-located microinverter.
Simple Overview of the Installation Procedure:
- Step 1 – Measure AC at the Electrical Utility Connection (See Enphase installation instruction sheet under "Documents" tab above)
- Step 2 – Install the AC Branch Circuit Junction Box (Not included)
- Step 3 – Position the Enphase Engage Cable
- Step 4 – Attach the microinverter to the Solar Racking (Optional)
- Step 5 – Dress the Enphase Engage Cable
- Step 6 – Terminate the Unused End of the Engage Cable
- Step 7 – Connect the Engage Cable to AC Junction Box
- Step 8 – Ground the System
- Step 9 – Complete the Installation Map
- Step 10 – Connect the 245 Watt Solar Panels
- Step 11 – Build the Virtual Array

NOTE, IMPORTANT Enphase Energy 4500W Package INSTALLATION: (OK, here is the scary legal disclaimer.) It is the responsibility of the purchaser to ensure that all products are installed and operated in accordance with local and national building codes as specific by the NEC (National Electric Code), UBC (Uniform Building Code) or IBC (International Building Code) and local utility company policy. These codes may vary from city to city and county to county. All Grid-tied solar installations should be permitted and inspected, where required, by the local inspection authority in the same manner as other equivalent electrical systems. One last thing. It is always a good idea to contract with a local licensed electrician to at least do the final electrical connection of your PV system from the AC disconnect to your home utility breaker box. Some local permitting authorities require that a licensed electrician do all the wiring from the rack to the utility interconnect. If you need help with the permitting documents for your 4500W solar kit, we are here for you. Solar permit service add on is available at checkout.
Additional Safety Instructions, 4500W Watt Solar microinverter Kit; Perform all electrical installations in accordance with all applicable local electrical codes and the National Electrical Code (NEC), ANSI/NFPA 70. Be aware that only qualified personnel should install or replace Enphase microinverter. Do not attempt to repair the Enphase microinverter in your 4500W Watt Solar Kit; it contains no user-serviceable parts. If it fails, please contact Enphase customer service to obtain an RMA (return merchandise authorization) number and start the replacement process. Tampering with or opening the Enphase microinverter will void the warranty. Before installing or using the Enphase microinverter, please read all instructions and cautionary markings in the technical description and on the Enphase microinverter System and the solar equipment. Connect the Enphase microinverter to the utility grid only after receiving prior approval from the electrical utility company. Be aware that the body of the Enphase microinverter is the heat sink. Under normal operating conditions, the temperature is 15°C above ambient, but under extreme conditions the microinverter can reach a temperature of 80°C. To reduce risk of burns, use caution when working with microinverter. Do NOT disconnect the solar module from the Enphase microinverter without first removing AC power.
