System description
The KP100L converts DC power obtained from the solar modules into the AC power that is used in businesses,
and enables interconnection with the grid.
This makes it possible to purchase power from the grid during periods when the load is high, and to sell power to
the grid during periods when the load is low. (Please note that a contract must be concluded with the grid for this
purchasing and selling transaction.) The system configuration of the KP100L is shown in the figure bellow.

MPPT (Maximum Power Point Tracking)
3 pairs of positive and negative DC input channels are connected to three sets of MPP Tracking.
The output power of solar modules varies depending on the sunshine irradiation and the temperature of the
modules. In order to use the unstable output of the solar modules efficiently, the KP100L searches for the
operating voltage that will produce the maximum output power while it converts the DC input voltage. The
KP100L has 3 MPPT. The topology of the MPPT is mainly a booster. Each booster steps up the DC input voltage
to a higher DC BUS voltage. User can connect differently-aligned string as 3 MPPT operate independently as
illustrated in the figure bellow. This construction achieves high power generation and flexible sizing of PV string.
DC Bus
The three sets of MPPT store DC power via the DC/DC booster to the DC bus.
DC/AC Inverter
The DC bus is connected to the DC/AC inverter, which converts DC power to AC power.
Grid-Connection Relays
The two relays, RLY1 and RLY2, control the connection of the KP100L to grid via CPU1 and CPU2.
Output Lines
4 output lines (L1, L2, L3 and N) and PE represent the 3-phase 4-wire AC power transmission to grid.

[example 3] PLC(Programmable Logic Controller):up to 4 units KP100L:up to 124 units
RS-232C Communications
The simplest and least expensive way to communicate between a single KP100L and a personal computer is to
connect directly via RS-232C ports. The maximum cable length between the personal computer and the KP100L
is 15 m.
