[. . . ] S102-E1-03 Grid Connect Photovoltaic Inverter KP100L-OD- Quick Installation Guideline Note: Dec, 2010 KP100L does not have the compatibility with thin-film module at this moment. The compatibility is under evaluation. Part number 2132254-1 C Introduction Introduction Thank you for choosing the KP100L Grid Connect Photovoltaic Inverter (hereinafter called "the KP100L"). This Quick Installation Guideline (hereinafter called "QIG") describes essential information regarding installation of the KP100L. The KP100L is designed for use in Grid Connect Solar Systems. [. . . ] To do a steady operation, install and use the product in places where the following situations are avoided. 1) Locations where surge voltage of the grid is generated by influence of neighborhood facilities and equipment. 2) Locations where the grid is unstable caused by influence of neighborhood facilities and equipment. 3) In factory or the vicinity where the grid is unstable. 4) Locations subject to noise that ungrounded consumer electronics generate. Store in locations where the temperature is within the range of -25 to 60°C (with no condensation or icing), and the humidity is 95 % maximum. Store in locations that is no more than 2, 000 m above sea level. Surge protection · · · Storage · · · 9 KP100L Quick Installation Guideline 1. Checking After Unpacking Checking the Accessories The follow items are included in the KP100L package. Check that all of the items shown in the package before you start the installation.

Typical System Configuration The figure below shows the typical system configuration of the KP100L. The equipments in AC and DC side are used depends on the design of the customer. · DC fuse · DC switch/breaker · SPD Solar module 1 · Ground fault breaker / RCD · AC breaker · SPD Solar module 2 Solar module 3 Applicable grid network The KP100L is designed to operate with grid network system type TT, TN as shown in the figure below. If the KP100L is connected to the different type of grid network such as IT, it may be fault occur. L1 L2 L3 PEN L1 L2 L3 N PE L1 L2 L3 N Connection with grid network type TN Connection with grid network type TT L1 L2 L3 N Impedance Connection with grid network type IT 11 KP100L Quick Installation Guideline 2. Typical System Configuration The KP100L is designed with grid network system type TT, TN. Then If you use transformer, connect the Neutral to the ground as shown in the figure below. 3P+N 3P Grid N 3P+N 3P+N Grid N Neutral in KP100L side should be connected to the ground. Applicable solar module The KP100L is designed to control the voltage of negative pole on solar module as same voltage level as Neutral of grid as shown in figure below. This can be achieved by new inverter circuit (ZCC). As a result, the voltage of negative pole on solar module is approx. According to this function, you can use the solar module which does not allow negative voltage on solar module. Applicable type of solar module is shown in the table below. Solar module manufacture requirement (1) No requirement (2) No negative voltages on solar module (3) Earthing of negative pole on solar module (4) No positive voltages on solar module (5) Earthing of positive pole on solar module Type of solar module Conventional silicon-based solar modules Some thin-film or silicon modules Some thin-film or silicon modules Specific solar module Specific solar module Applicable or not KP100L can be used. [. . . ] The display moves to the display of the setting of the country when you start KP100L with Country Setting not fixed. Table shows the relation between the menu and the country. You can't set the country other than countries shown in the table. The KP100L complies with local and national standards when correct country is selected. [. . . ]
