The SolarWorld Enphase Microinverter System simplifies design and installation by alleviating string-sizing constraints, and it optimizes the energy harvest of each module through independent maximum power point tracking (MPPT). An Enphase System consists of microinverters, Engage trunk cables, the Envoy Communications Gateway, and the web-based Enlighten monitoring and analysis service.
The Enphase M250 Microinverters are installed at each SolarWorld panel, maximizing energy production and converting the DC power from the panel into standard AC electricity. This offers greater design flexibility and simplified installation, accommodating different roof planes, pitches, or rooftop obstacles. The first to introduce module-level microinverters, Enphase technology maximizes safety and design flexibility. The M250 Microinverters are covered by a 25-year limited warranty. Each Enphase Microinverter is individually connected to one solar panel in your array. This unique configuration means that an individual Maximum 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 panels in the array.
The M250 Microinverter is connected to the AC branch circuit using the Engage cable system. The Engage Cable is a continuous length of 12AWG cable with per-installed connectors for the Enphase Microinverters to plug into. The cable is handled like standard outdoor-rated electrical wire, allowing it to be cut, spliced and extended as needed. The Engage system is comprised of ruggedized cabling and accessories that enable fast, easy installations of the Enphase system. Snap-together connectors and waterproof enclosures deliver a streamlined, secure, and standardized approach to array wiring unique to the Enphase System.
Each of the microinverters that makes up the SolarWorld 4320W grid-tie 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.
SolarWorld’s Sunmodule solar panels are recognized as one of the leaders in setting industry standard in quality. SolarWorld stringently control the entire manufacturing process, ensuring high performance in each and every panel.

Best Practice: Center-feed the branch circuit to minimize voltage rise in a fully-populated branch. This practice greatly reduces the voltage rise as compared with an end-fed branch. To center-feed a branch, divide the circuit into two sub-branch circuits protected by a single overcurrent protection device (OCPD).
|3.0kW AC Coupled Backup This home battery backup kit allows you to use your Enphase solar system to charge 10,752 watts of battery off-grid backup to home solar system with an option for 21,500 watts. If your system is 3600 watts or less or with the Enphase system that is larger we can isolate 3600 watts to use for this application, you can add this cost effective backup and leave the lights on during utility power outages.||BP9344487|
*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.

SolarWorld Enphase 4320W Grid-Tie Kits are relatively simple to layout and install. You will not need string calculations, just keep your string to a maximum of 16 270 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.
NOTE, IMPORTANT INSTALLATION: 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-Tie solar installations should be permitted and inspected, where required, by the local inspection authority in the same manner as other equivalent electrical systems. Blue Pacific Solar recommends you contract with a local licensed electrician to do the final electrical connection of your SolarWorld Enphase 4320W grid-tie 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 kit, we are here for you. Solar permit service add on is available at checkout.
Additional Safety Instructions; 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; 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.
