    Prostar mppt grid-tie inverter 4kw for home solar system

    Prostar single phase inverter is a new generation of PV string inverter which has been developed by Prostar for residential users. Single Phase inverters have the advantages of compact size, light weight, easy installation and maintenance, and are above all cost efficient.

    Prostar grid tie inverters produce the pure sine wave that is compatible with the alternating current waveform produced by your utility company. Sine wave inverters are a little more expensive, but they are compatible with almost all equipment and appliances that can be operated with power that comes from the grid. These multifunction inverters also allow you to send excess power to your utility company, in essence storing excess energy in the grid. Grid-tie inverters can be used to keep a back-up battery bank charged for emergency power in case of a utility power failure.

    Inverters Key Features

    AFCI protection shuts down the inverter in the event of an arc fault

    DC Disconnect and DC reverse polarity protection

    Innovative mounting system makes installation and servicing extremely user-friendly and quick. The inverter is simply placed in the wall bracket and then secured.

    Field serviceable for lowest cost of ownership - no need to remove the entire inverter for servicing, just the power stage set compartment. All the cabling, settings and configurations remain in place.

    Max. Efficiency 98%, CEC Efficiency 97%

    Sans-transformer design and high power density, offers lighter and more convenient installation

    5 years standard warranty

    Designed with latest thermal simulation technology for longer service life.

    Grid tie Inverter Characteristics

    Rated output power: This value will be provided in watts or kilowatts. For some inverters, they may provide an output rating for different output voltages. For instance, if the inverter can be configured for either 240 VAC or 208 VAC output, the rated power output may be different for each of those configurations.
    Output voltage(s): This value indicates to which utility voltages the inverter can connect. For smaller inverters that are designed for residential use, the output voltage is usually 240 VAC. Inverters that target commercial applications are rated for 208, 240, 277, 400, or 480 VAC and may also produce three phase power.
    Peak efficiency: The peak efficiency represents the highest efficiency that the inverter can achieve. Most grid-tie inverters on the market as of July 2009 have peak efficiencies of over 94%, some as high as 96%. The energy lost during inversion is for the most part converted into heat. This means that in order for an inverter to put out the rated amount of power it will need to have a power input that exceeds the output. For example, a 5000 W inverter operating at full power at 95% efficiency will require an input of 5,263 W (rated power divided by efficiency). Inverters that are capable of producing power at different AC voltages may have different efficiencies associated with each voltage.
    CEC weighted efficiency: In contrast to peak efficiency, this value is an average efficiency and is a better representation of the inverter's operating profile. Inverters that are capable of producing power at different AC voltages may have different efficiencies associated with each voltage.
    Maximum input current: This is the maximum amount of direct current that the inverter will use. If a DC power source, such as a solar array, produces an amount of current that exceeds the maximum input current, that current will not be used by the inverter.
    Maximum output current: The maximum output current is the maximum continuous alternating current that the inverter will supply. This value is typically used to determine the minimum current rating of the over-current protection devices (e.g., breakers and fuses) and disconnects required for the output circuit. Inverters that are capable of producing power at different AC voltages will have different maximum outputs for each voltage.
    Peak power tracking voltage: This represents the DC voltage range in which the inverter's maximum point power tracker will operate. The system designer must configure the strings optimally so that during the majority of the year, the voltage of the strings will be within this range. This can be a difficult task since voltage will fluctuate with changes in temperature.
    Start voltage: This value is not listed on all inverter datasheets. The value indicates the minimum DC voltage that is required in order for the inverter to turn on and begin operation. This is especially important for solar applications, because the system designer must be sure that there is a sufficient number of solar modules wired in series in each string to produce this voltage. If this value is not provided by the manufacturer, system designers typically use the lower band of the peak power tracking voltage range as the inverter's minimum voltage.
    IPxx rating: The Ingress Protection rating or IP Code classifies and rates the level of protection provided against the ingress of solid foreign objects (first digit) or water (second digit), a higher digit means greater protection.
