On Grid Solar Power Plant Guidance
On Grid Solar Power Plant (SPP) Planning is made by design and size based on
public tender documents and explanatory reports. On Grid SPP is a power plant
whose power generation components (solar modules), inverters (off grid), and
monitor/display devices, are placed and assembled in one area that is integrated
or very close together, then the electricity is supplied to the target point (house)
through distribution networks and house connections. To overcome the voltage
drop due to the distance between the generator and the house, the On Grid SPP
system uses the AC (alternating current) system output, Medium Voltage Network
(MVN) and Low Voltage Network (LVN).

The scope of, installation, activities includes the installation and construction
of solar modules, electronic rooms, quard rooms/offices, cable networks and
home Installations. The following sections describe the detailed planning of
each PV mini-grid component and sub-system and installation instructions.
General Explanation
On grid SPP system which has been described above consists of the main
components which include:
1. Solar Module
2. Solar Inverter
3. Accessories
Judging from the form of activity, the installation of On Grid SPP System
includes mechanical, electrical and civil works.
Electrical work includes:
▪Solar module installation and wiring work.
▪Inverter junction / jumper cable installation system, SCR, inverter,
and distribution panel
▪Network pole installation and customer home installation.
Mechanical work includes:
▪Installation of the upper frame on the Rooftop
▪Cable and Inverter Installation
▪Installation of Distribution Panels and connectors to KWH meter.
Solar Module
The solar module is installed as the roof of the house. The solar modules are
assembled and mounted on the roof battens of the house so that the
arrangement of the modules is rectangular.
The module support must be strong to withstand loads and forces that can
cause deformation of the module surface. All module supports are made of
hot dip galvanized iron to provide protection against rust. To facilitate
transportation, the batten and rib module supports are made in the form of a
knock down.
PART 2: INSTALLATION

Inverter
The inverter used is a Hybrid inverter (DC/AC). The inverter work
automatically and there is no need to ON/OFF manually. The inverte will
supply AC power to the distribution panel, then it will be distributed to the
network.
Disconnector
It is a switch that functions to connect and disconnect the inverter voltage.
Panel Disconnector
It is a switch that functions to connect and disconnect the battery voltage and
inverter input.
Load Disconnector
ls a 50A MCCB which functions to connect and disconnect low voltage.
Wiring System
For the safety of installation personnel and operators, before carrying out the
work the following points should be observed:
▪Electrical work is carried out by at least two people and only carried out by
officers who have been tested to work at high voltages (DC or AC voltage)
and have mastered the overall system design.
▪Please remember that when the sun shines the open voltage of the solar
module can reach 1000 VDC, so it is very dangerous.
▪DC voltage is always formed without realizing it (DC voltage does not give a
shock effect) it often happens that our bodies contact with the battery poles
while working, this can be fatal.
▪Inverter short circuit current exceeds 1000 A.
▪When using mechanical tools, such as screwdrivers, pliers and wrenches
should be used with care, if possible, use properly insulated equipment.
▪Use footwear that has good insulation, if possible, use shoes specifically
designed for electrical work.
▪Check that all switches, fuses, and MCBs are in the "OFF" position.
▪The ends of the cable must be equipped with the appropriate cable shoes.
▪Think carefully about the steps to be taken, then do it gradually, carefully and
avoid rushing conditions.

The cable that will be installed in the On Grid SPP system must be adjusted to
the voltage capacity and the amount of current to be flowed. This needs to
be done to avoid energy losses and maintain electrical safety.
Solar Module Circuit
▪Make sure all switches and fuses on the generator Box MCB
module are "OFF".
▪The solar modules are arranged in series of 20 modules to form an array of
solar modules.
▪Connect the positive, Pole of the module to the blocking diode terminal,
arrester and MCB 10 A on the MCB box then connect it to the inverter and
the negative pole directly to the inverter.
▪The cable used is a 4 mm2 NYAF cable.
Inverter System Circuit
▪Make sure all switches or cam switch, MCCB in the "OFF" position.
▪Connect the output of the inverter to the MCCB on the distribution panel,
connect the inverter output for the black line to the AC cam switch whose
output is connected to the MCCB and the blue one directly to the MCCB.
Make sure that the polarity of the cable is not reversed and tight or loose.
Grounding System Circuit
The grounding system must be carried out on all sub-system components.
The entire installation must be equipped with arresters (high voltage
protection) which may occur due to the induction of an electric field during a
lightning strike.
With the completion of the wiring and installation of the On Grid SPP system,
it is ready to undergo testing and commissioning.

Operating Instructions
The electrical energy produced by On Grid SPP is limited by the capacity of the
available solar modules, so there needs to be a limiter for electricity consumption
or a kWh/VAh limiter. The advantages of this tool are:
1. It has a display of energy consumption, and the remaining available energy
that can still be used (0-100%) and a short circuit warning.
2. It has a warning sign in the form of an LED bar that informs the user of how
much energy balance is remaining.
3. The dimensions of the tool are compact and compact because it uses an
electronic system.
4. The customer does not have the authority and cannot set the limit value for
energy consumption, because this tool is set using a handheld and requires
special knowledge.
5. The setting of the daily Wh usage limit and factory default reset time have
been set, but can be changed by field technicians, without the need for a
computer. Just use a handheld.
6. It has facilities that can cut off and reconnect electricity to problematic
customers.
7. It has an electrical protection function, so it does not require replacement of
components in the event of a short circuit.
8. It has a seal to prevent electricity theft.
Safety System
1. The diode in the solar module cable functions as a preventer from backflow
from the inverter to the solar module through the cable.
2. MLB is a circuit breaker for DC system, which can disconnect or manually
connect the connection between the solar module and the inverter whenever
needed.
3. NH Fuse is a fuse that will break if there is a sudden surge in current that
exceeds its capacity, so that the inverter is protected from damage.
4. Cam switch is a manual breaker / connection component between the battery
and the inverter, which can be used if a problem occurs, or you want to
perform maintenance or inspection on the battery or inverter.
PART 3: HOW TO USE

5. The MCCB on the distribution panel can be used to disconnect or connect the
inverter with the JTR. The MCCB needs to be lowered if a temporary
disconnection to JTR is required for reasons of maintenance or repair.
6. The fuse in the customer's house is needed to prevent the lights or consumer
electronic equipment from being damaged in the event of a power surge,
because the fuse will break first.
7. The MCB in the consumer's house can be used to disconnect or connect the
home installation cable to the JTR. This is necessary when it is necessary to
repair or replace the switch or socket in the consumer's home.
8. Grounding is the connection of PE and/or Neutral cables into the ground
through embedded iron rods. This groundinga is installed in the powerhouse
(covering all components), JTR (starting and ending poles), and in every
consumer's house. This grounding system serves to
9. Absorbs and distributes induced lightning strikes into the ground, so that the
PV mini-grid system components.
10. On Grid and consumer electronic equipment is not damaged.
Safety Operation
1. Normal Start-up Procedure
Normal start up needs to be done during the Centralized PV mini-grid system
after undergoing a normal shutdown for repair and/or maintenance, either in
whole or in part. The steps for normalizing the system are basically the same
as those performed during commissioning.
2. Normal shut-down Procedure
If maintenance and/or repair activities are related to electrical problems from
the On Grid SPP system, then for the Safety of officers and equipment
security, all connections between sub-systems, especially batteries and
photovoltaics, must be removed.
Normal shut-down steps are carried out as follows:
a) Position the MCCB main switch on the distribution panel in the “OFF” position.
b) Position the module MCB switch and AC cam switch on the “OFF” position.
c) Turn off the Inverter.
d) Lower the DC cam switch to the OFF position.
3. Emergency Procedure
If a very dangerous situation occurs, such as the occurrence of a short circuit
from each electrical section, the PLTS On Grid System must be immediately
turned off by lowering the MCCB on the distribution panel, then do the same
as in the normal shut-down procedure.

4. Normal Operation Procedure
When turning on the system, the first step that must be considered is to raise
the DC Cam switch to the ON position then position the DC Breaker to ON
then the inverter will turn on.
In the morning before the radiation has not provided enough energy to meet
the electricity demand, the sun's intensity will slowly increase, until a time
when the entire electrical load can be fully supplied by photovoltaics. If the
intensity of the sun continues to increase, some of the excess electricity will
be saved to power grid.
If solar radiation continues to increase and enters the running load so that it
gradually reaches the fully covered level, then part of the photovoltaic
generator will be transferred to power grid. In the afternoon when the sun's
rays start to weaken, power grid will start to be active again releasing some of
its electricity to the load. Demand for electricity will continue to increase
steadily towards sunset, while charging from photovoltaic will stop
completely. In this situation, all electricity demand will be supplied by the
Inverter until a time when the electricity reserves from the Solar Panel are
nearing exhaustion. With low electricity demand at midnight and early
morning, it is hoped that this demand can be fully supplied from the inverter
using a solar panel power source. After morning, the same process will be
repeated. In the rainy season, the electricity process will decrease causing the
charging load to not be maximal. So, it is expected that the burden will be
transferred to power grid.
