The SolarEdge grid-tied system combines panel-level power optimizers and monitoring with a specialized DC-AC string inverter to maximize the energy yield of a solar installation with maximum power point tracking (MPPT) on each panel that mitigates partial string shading, panel mismatch, uneven soiling and aging variance losses. The system is designed to automatically maintain a fixed string voltage to ensure that the inverter always operates as efficiently as possible, regardless of string size, shading, or temperature. This allows flexible string length ranging from 8 to 25 panels and mitigates the performance impact of varying panel sizes, tilts or orientations. The installation is scalable and facilitates expansion or replacements because future modules do not need to match existing ones. pre-engineered Installing a SolarEdge system can reduce installation time and cost by decreasing the number of strings, DC disconnects and other balance of system parts.

SolarEdge Technologies provides electronics to that act similar to micro inverters at a panel level but uses a central inverter to maximize energy harvesting. The SolarEdge technology is unique in that it uses a system in which each solar panel is connected to a power optimizer which guarantees maximum power to be drawn from each panel throughout the day then feeds the energy that it generates through a central inverter on the wall to the utility grid. The SolarEdge solution provides some unique benefits with their system, such as increased energy product per panel, improved safety for the DIY installer, and panel level performance monitoring. The SolarEdge power optimizers are designed to function continuously for over 25 years without maintenance in outdoor conditions with extremely low failure rates. The SolarEdge inverter is designed, and warranted, for 12 years of operation.

In a SolarEdge system, a power optimizer (Powerbox) is mounted behind and connected to each panel. At least 8 panels power optimizer  must be used, so your system can start as small at 8 panels with wattages up to 350 watts each. The output of the power optimizer are wired in series “strings” just like a typical grid connected system, but strings can be made of 8 to 25 panels and several strings of different numbers of panels may be connected to the same SolarEdge inverter. This allows the homeowner to put as many solar panels on a roof that can fit in allowable space. Panels can be partially shaded and can even be on different planes of the roof. Different brands and wattage panels can be used in the same string, making it easy to add to an existing system later or to replace a failed or broken panel. When the panels with power optimizer are installed, the homeowner can safely handle the wiring because there is only one volt output per panel until they are connected to the inverter and the inverter is turned on. The installer will know if the wiring is correct by counting the panels and making sure there is one volt per panel in each string. This allows for the quantity in series and the polarity to be easily verified.

Blue Pacific Solar has provided all of the main parts you will need for your 4000W solar kit. Here are some additional items that your may need prior to installing your package. Conduit, appropriately sized electrical wire from the array, some fasteners and grounding rod and wire. Building and installing your own home solar system is not only the smart choice for controlling your expenses, it may be on the most satisfying DIY projects you ever have undertaken.

Added Energy



  • Power optimizers have higher efficiency (99.5%) than Microinverters
  • Reduced efficiency of Microinverters increases heat dissipation
    which enhances module degradation
  • Microinverters have a higher minimum voltage than power
    • Less shading tolerance
    • Late wake up leading to fewer production hour




  • Microinverters have a limited AC output power (e.g. no support for 72-cell modules)
  • When connected to higher capacity modules, the excess DC power is
    lost. E.g. in a 6kW installation of 260W modules, only 5kW AC power
    will be produced




  • Microinverters have much higher part count leading to increased
    failure rate
  • Some Microinverters work with electrolytic capacitors which have
    short life time
  • Microinverters create higher temperatures

The SolarEdge inverters sync with the grid at 240 VAC, and because the MPPT and voltage management is handled by the power optimizer, have built-in AC and DC Disconnects, weigh just 52 pounds, and are 97% efficient. The system also offers optional wireless inverter connectivity for simpler installation, free of Ethernet or RS485 cabling. ETL Listed to UL 1742 for the US and Canada. SolarEdge has a 25-year warranty for the power optimizer and 12-year warranty for the inverter, extendable to 25 years. Current residential solar systems are typically built from ten to 50 solar panels connected in a series-parallel connection. Several panels (typically 10 to 15) are connected in series, forming a string, to achieve a voltage high enough to enable efficient DC/AC inversion usually between 150V to 600V. More power can be added to the system by adding multiple strings in parallel.

Since the strings are connected in parallel, each string must have the same operating voltage. Thus, in order to efficiently produce power each string must match others in operating voltage. This generally includes matching in panel make and model, string length and orientation and shading conditions, to name a few parameters. The entire array is connected to a solar inverter which is responsible for harvesting the electrical power and inverting it to AC so it can be fed into the grid. If an array consists of two strings with differing operating voltage characteristics (e.g. panel model or panel orientation), two inverters will be needed.

The series connection in each string also poses problems that reduce the maximum power available for inversion. This stems from the fact that the same amount of current flows through all of the panels of each string, disabling individual panel power maximization. SolarEdge is different in that they introduce a distributed power harvesting architecture at the panel level, in that way, the SolarEdge system overcomes the limitations present in current PV systems. Instead of using a single power harvesting device, an inverter, for the entire array, SolarEdge divides power harvesting functions between two devices: solar panel integrated Maximum Power Point Tracking (MPPT) units. These units optimize the energy output from each panel.

The SolarEdge inverter handles only DC to AC inversion, not high power MPPT, schemes. Further, because this inversion is handled at a fixed DC voltage, the inverter can be a simpler, more cost-effective device. Well performing Balance of System components, among them the inverter, are of high importance to the overall performance and longevity of a solar system. The SolarEdge distributed architecture approach contributes to improved system performance. In addition, quality of installation is of critical importance to system performance. SolarEdge systems allow for simplified installation, therefore posing fewer complications and potential errors when installing your SolarEdge package.

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-tied 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 solar 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 SolarEdge optimizer. Do not attempt to repair the SolarEdge optimizer; it contains no user-serviceable parts. If it fails, please contact SolarEdge customer service to obtain an RMA (return merchandise authorization) number and start the replacement process. Tampering with or opening the optimizer will void the warranty. Before installing or using the optimizer or inverter, please read all instructions and cautionary markings in the technical description and on the solar equipment. Connect the SolarEdge kit to the utility grid only after receiving prior approval from the electrical utility company. Be aware that the body of the optimizer is the heat sink. Under normal operating conditions, the temperature is 15°C above ambient, but under extreme conditions the optimizer can reach a temperature of 80°C. To reduce risk of burns, use caution when working with optimizer. Do NOT disconnect the solar module from the SolarEdge optimizer without first removing AC power.


*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.

This SolarEdge 4000W Solar Kit is an affordable expandable do-it-yourself (DIY) high quality solution for your home or businesses energy independence.
