Introduction.
In accordance with local and international standards, the protection of equipment and
people is required to ensure the safe operation and maintenance of electrical products,
appliances or devices.
This AC protection is designed for both the protection and safe operation of the Solar
inverter it is designed for.
WAR I G: Installation of this AC Protection board to be by qualified personnel only
WAR I G: Electricity is dangerous- Please ensure the correct tools and personal protective
equipment is used when Installing, Wiring or Operating Electrical Equipment
WAR I G: Although all precautionary measures are taken into account during
manufacturing it is the responsibility of the installer of this product to ensure that it
installed in accordance with the relevant bylaws applicable to embedded generation
systems and low voltage electrical equipment
WAR I G: This Electrical board has an IP65 rating, and is suitable for outdoor mounting.
WARNING: All terminations should be checked for any potential loose connections that may
have occurred as a result of transport activities and vibration. Loose connection may cause
hot connections that could lead to damage and/ or fire

Installation should where possible be done out of direct sunlight, direct water spray, and
rain. If this is not possible, it is recommended the board is to be fitted with a suitable rain
and sun canopy to protect from direct sunlight and rain or spray.
WAR I G: In accordance with local bylaws and installation and wiring of premises, this
board should be installed in such a manner that maintenance and inspection can be carried
out without the use of special tools or equipment, such as ladders and scaffolding.
Description
This AC Board is designed for the connection and protection of 5 x Solis 110KW grid
connected inverters.
The inputs of the 5 inverters is combined in parallel and a single point of output is
provided.
The board is also equipped with a Type 1 & 2 AC Surge protection device intended for the
protection of the inverters and other equipment from surges originating from the utility
supply side of the installation.
Two variations of this product are available, as per the ordering code below.

Mounting:
The board is designed to be Floor Standing. Please ensure that the chosen surface is suitable
in order to support the weight of the board.
Please ensure enough clearance area below the board to facilitate the incoming and
outgoing cables can be installed in such a way to maintain the cable manufacturers
recommended bending radius. See Fig 1.

Connecting the inverters:
This AC Board is suitable for the connection of 5 x Solis 110K-4G Inverters
Each inverter is connected to its own circuit breaker, and will be protected individually.
Recommended cable entry point is from the bottom of the enclosure. See Fig 2.
Fig 2.
ote: Please use the appropriate cable gland for the cable type that is used for the
installation.
For SWA cable: Steel wire armoured gland with cone
For Flexible cable ie. H07-R F- suitably selected IP 65 Compression gland
In all instances ensure the use of the matching shroud to protect the gland and assist with
ingress protection. See Fig 3,3a, and 4 below.

Power Quality meter
The ACDB meter version with Power Quality meter has been pre-configured for the
appropriate CT current setting, no further setting is required by the user
The power quality meter is used as a tool to assess the performance of the PV plant.
All values are there in relation to the production characteristics of the PV plant including the
power factor and harmonic values
Other values include current per phase and total kWh energy delivered by the plant
WAR I G: Please ensure all connections including factory connections are checked as it
could have become loose due to transport and handling.
The ACDB is supplied with the appropriate marking and rating labels, please ensure any
additional warning or rating information is added to the system as may be required due to
site specific conditions and location.
SAFETY FIRST- Equipment to be inspected and tested by suitably Qualified person
