2 Design
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. zero. According to this function, you can use
the solar module which does not allow negative voltage on solar module.

Do not use the solar module that require earthing of negative or positive pole. Otherwise, the failure might occur.
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
Note: Dec,2010
KP100L does not have the compatibility with thin-film module at this moment.
The compatibility is under evaluation.
