6. Check List
Each of the Inverter has been installed to be used in accordance with the instructions listed in the
manual or the product specification; eg. ambient temperature, annual operation time, installation place,
no direct exposure to sun light and direct rain fall, mounting distances and protection against toxic gas
and other harmful gas environment, dust and other contamination.
Ensure that you have checked and verified the following points:
The provided mounting base plate for the KP100L is attached and fixed securely and correctly.
The inverter is mounted securely in the mounting base plate.
There has been no use of parts or accessory other than Omron has provided and/ or specify.
There has been no drop-off of the inverter or damage given when the inverter are installed and
set up.
There has been no mechanical stress, which applies continuously yet negligible, such as
vibration or shock to the inverter.
The heat sink of the inverters is purged to avoid any clog of air convection and do not place any
objects close to the air duct.
All the wires and cables are connected to correct polarity.
MC connectors have been fastened and not deteriorated.
“Screws of AC cable” has been fastened.
Cover foreside R has been fastened and the cable clamps have been tightened correctly.
Solar modules have been installed properly and they perform as designated.
Open circuit voltage MUST not exceed 850 VDC under operating temperature (-20 to +60°C).
Short-circuit DC current MUST not exceed 13 A DC per one DC input.
Cables on AC side have low resistance enough to constrain an increase of grid voltage at the
terminal of connection (or other side of grid transformer) and loss is less than 1% of rated power of
the inverter.
There has been a protection against lightening surge put on DC side of the inverter, in particular,
in a place where it is often seen
There has been a protection against surge noise (spike) and grid instability on AC grid lines to
avoid any adverse influence from a nearby construction work or similar unusual event
There has been a protection against a less quality grid connection, in particular, in an industrial
estate or near one
There has been no modifications performed by a party other than OMRON in a product
specification.
There has been no other apparatus without grounding (eg. washing machine) on the same grid
lines.
There has been no installation or set-up such as that cause the inverter to chatter repeatedly
intervention and re-generation of power at startup and stop.
