For Calculating ONLY with SolarEdge Optimizers and Equipment
We assume an MPP voltage for each
module (given perfectly matched modules for demonstration purposes) of
VMPP = 32V.
This means the input voltage to the power optimizer is 32V, and the input
current is 30OW/32V =9.37A.
The input voltage to the inverter is controlled by a separate feedback loop.
For simplicity, in calculation the inverter requires a constant 350V. Since
there are TWELVE (12) serially - connected modules, each providing 30OW,
the input current to the inverter is 360OW/350V = 10.28A.
Thus, the DC bus current flowing through each of the power optimizers must
be 9.00A. This means that each power optimizer in this example provides
an output voltage of 30OW/10428 = 29.18V. In this case, the power
optimizers are acting as up converters, converting the 29.18V input voltage to
the target 29.18V output voltage.
The various system currents and voltages in this case are illustrated in

The SolarEdge system maintains a fixed string voltage regardless of string
characteristics and environmental conditions. This application note details the
concept of operation of the SolarEdge fixed string voltage and its benefits.
Concept of Operation
The SolarEdge power optimizer is a DC -DC power optimizer integrated into each
module, replacing the junction box. The power optimizers, using An input control loop,
perform per module MPPT and enable performance monitoring of each module. In an
independent process, the power optimizers enable the inverter to automatically
maintain a fixed string voltage, at the optimal point for DC -AC conversion by the
inverter, regardless of string length and individual module performance.The operating
principles of the SolarEdge system are illustrated in the following example which
examines a system's behavior under varying conditions.
The example system consists of 10 20OW modules. Each module has a power
optimizer connected to it, which is essentially a DC /DC buck -boost converter with an
MPPT controller. The power optimizers areserially- connected to form a string; multiple
strings can be connected in parallel to the same input of the SolarEdge inverter. The
SolarEdge inverter is a single stage current source - it continuously adapts the current
it draws from the PV array in order to keep the input voltage constant.
The SolarEdge power optimizer is highly efficient, maintaining over 98.8% weighted
conversion efficiency over a wide range of conditions. However, for calculation
simplicity, we assume 100% power optimizer efficiency in this example.
Fixed String Voltage Benefits
The fixed string voltage maintained by SolarEdge power optimizers provide multiple benefits:
❑ Flexible Design — mismatched .modules can be seriallyyconnected in a string. The number of
modules in a single string is not dependant on module output voltage and therefore a wide
string length range is permittedi.
High Inverter efficiency and Reliability — the SolarEdge inverter components work at a fixed
voltage, operating under less stress. The inverter always operates at a Voltage that enables
optimal DC-AC inversion efficiency, independent of string length or environmental conditions.
Reduced Installation Cost - longer strings, lower BoS element count And installation 'cost and
labor.
F1 Temperature Indifference - the SolarEdge fixed string Voltage completely removes the
temperature constraints which strongly limit string length in traditional systems.
F1 Improved Safety - all power optimizers start up in "safety 1V output" mode until the power
optimizers are connected to a functioning SolarEdge inverter. Additionally, in the event of a grid
power shutdown, the modules immediately stop producing power and revert to this mode.

Rower. optimizer Theoa of Ogg�ation and Descral2twon
A power optimizer is a DC to DC converter technology developed to maximize the energy harvest from solar photovoltaic or wind turbine systems. They
do this by individually tuning the performance of the panel or wind turbine through maximum power point tracking, and optionally tuning the output to
match the performance of the string inverter. Power optimizers are especially useful when the performance of the power generating components in a
distributed system will vary widely, differences in equipment, shading of light or wind, or being installed facing different directions or widely separated
locations.
Power optimizers for solar applications, can be similar to microinverters, in that both systems attempt to isolate individual panels in order to improve
overall system performance. A microinverter essentially combines a power optimizer with a small inverter in a single case that is used on every panel,
while the power optimizer leaves the inverter in a separate box and uses only one inverter for the entire array. The claimed advantage to this "hybrid"
approach is lower overall system costs, avoiding the distribution of electronics.
Maximum power point tracking (MPPT)
Most energy production or storage devices have a complex relationship between the power they produce, the load placed on them, and the efficiency of
the delivery. A conventional battery, for instance, stores energy in chemical reactions in its electrolytes and plates. These reactions take time to occur,
Which limits the rate at which the power can be efficiently drawn from the cell.[1] For this reason, large batteries used for power storage generally list two
or more capacities, normally the "� hour" and "20 hour" rates, with the 2 hour rate often being around 50% of the 20 hour rate.[2]
The drawback to this approach is that MPPT system can only be applied to the array as a whole. Because the IN curve is non - linear, a panel that is
even slightly shadowed can have dramatically lower output, and greatly increase its internal resistance. As the panels are wired in series, this would
cause the output of the entire string to be reduced due to the increased total resistance. This change in performance causes the MPPT system to
change the operation point, moving the rest of the panels away from their best performance.[7]
Because of their sequential wiring, power mismatch between PV modules within a string can lead to a drastic and disproportionate loss of power from
the entire solar array, in some cases leading to complete system failure.[81 Shading of as little as 9% of the entire surface array of a PV system can, in
some circumstances, lead to a system -wide power loss of as much as 54 %.[9] Although this problem is most notable with "large" events like a passing
shadow, even the tiniest differences in panel performance, due to dirt, differential aging or tiny differences during manufacturing, can make the array as
a whole operate away from its best MPPT point. "Panel matching" is an important part of solar array design.
Isolating, ag nels
These problems have led to a number of different potential solutions that isolate panels individually or into much smaller groups (2 to 3 panels) in an
effort to provide MPPT that avoids the problems of large strings.
One solution, the microinverter, places the entire power conversion system directly on the back of each panel. This allows the system to track the MPPT
for each panel, and directly output AC power that matches the grid. The panels are then wired together in parallel, so even the failure of one of the
panels or microinverters will not lead to a loss of power from the string. However, this approach has the disadvantage of distributing the power
conversion circuitry, which, in theory, is the expensive part of the system. Microinverters, at least as late as early 2011, had significantly higher price per
watt.
This leads, naturally, to the power optimizer concept, where only the MPPT system is distributed to the panel's. In this case the conversion from DC to
AC takes place in a single inverter, one that lacks the MPPT hardware or has it disabled, According to its supporters, this "hybrid" approach produces
the lowest -cost solution overall, while still maintaining the advantages of the microinverter approach.

Ufer ground
The Ufer Ground is an electrical earth grounding method developed during World War II. It
uses a concrete - encased electrode to improve grounding in dry areas. The technique is used in
construction of concrete foundations.
Construction: Concrete is naturally basic (has high pH). Ufer observed this means that it had a
ready supply of ions and so provides a better electrical ground than almost any type of soil.
Ufer also found that the soil around the concrete became "doped ", and its subsequent rise in
pH caused the overall impedance of the soil itself to be reduced.[3] The concrete enclosure
also increases the surface area of the connection between the grounding conductor and the
surrounding soil, which also helps to reduce the overall impedance of the connection.
Ufer's original grounding scheme used copper encased in concrete. However, the high pH of
concrete often causes the copper to chip and flake. For this reason, steel is often used instead
of copper. When homes are built on concrete slabs, it is common practice to bring one end of
the rebar up out of the concrete at a convenient location to make an easy connection point for
the grounding electrode. [4] Ufer grounds, when present, are preferred over the use of
grounding rods. In some areas (like Des Moines, Iowa) Ufer grounds are required for all
residential and commercial buildings.[5] The conductivity of the soil usually determines if
Ufer grounds are required in any particular area.
An Ufer ground of specified minimum dimensions is recognized by the U.S. National
Electrical Code as a grounding electrode. [6] The grounding conductors must have sufficient
cover by the concrete to prevent damage when dissipating high - current lightning strikes. [71
A disadvantage of Ufer grounds is that the moisture in the concrete can flash into steam
during a lightning strike or similar high energy fault condition. This can crack the surrounding
concrete and damage the building foundation.[8]
SLINGSHOT POWER. CO
As the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely related. Under certain conditions, a conductor
used to connect to a system neutral is also used for grounding (earthing) of equipment and structures. Current carried on a grounding conductor can result in
objectionable or dangerous voltages appearing on equipment enclosures, so the
installation of grounding conductors and neutral conductors is carefully defined in electrical regulations. Where a neutral conductor is used also to connect
equipment enclosures to earth, care must be taken that the neutral conductor never rises to a high voltage with respect to local ground.
Definitions
Ground or earth in a mains (AC power) electrical wiring system is a conductor that provides a low impedance path to the earth to prevent hazardous voltages from
appearing on equipment (the terms "ground" (North American practice) and "earth" (most other English - speaking countries) are used synonymously here). Under
normal conditions, a grounding conductor does not carry current. Neutral is a circuit conductor that carries current in normal operation, which is connected to
ground (or earth).
In a polyphase or three -wire (single- phase) AC system, the neutral conductor is intended to have similar voltages to each of the other circuit conductors. By this
definition, a circuit must have at least three wires for one to serve as a neutral. In the electrical trade, the conductor of a 2 -wire circuit that is connected to the
supply neutral point and earth ground is also referred to as the "neutral ".[1]
The NEC and Canadian electrical code only define neutral as the first of these. In North American use, the second definition is used in less formal language but
not in official specifications. In the UK the IET definition of a neutral conductor is one connected to the supply system neutral point, which includes
both these uses.
All neutral wires of the same electrical system should have the same electrical potential, because they are all connected through the system ground. Neutral
conductors are usually insulated for the same voltage as the line conductors, with interesting exceptions. [2]
Circuitry
Neutral wires are usually connected at a neutral bus within panelboards or switchboards, and are "bonded" to earth ground at either the electrical service entrance,
or at transformers within the system. For electrical installations with three -wire single phase service, the neutral point of the system is at the center -tap on the
secondary side of the service transformer. For larger electrical installations, such as those with polyphase service, the neutral point is usually at the common
connection on the secondary side of delta/wye connected transformers. Other arrangements of polyphase transformers may result in no neutral point, and no
neutral conductors. Combining neutral with earth Stray voltages created in grounding (earthing) conductors by currents flowing in the supply utility neutral
conductors can be troublesome. For example, special measures may be required in barns usedfor milking dairy cattle. Very small Voltages, not usually perceptible
to humans, may cause low milk yield, or even mastitis (inflammation of the udder). [3] So- called "tingle voltage filters" may be required
in the electrical distribution system for a milking parlour. Connecting the neutral to the equipment case provides some protection against faults, but may produce a
dangerous voltage on the case if the neutral connection is broken. Combined neutral and ground conductors are commonly used in electricity supply companies'
wiring and occasionally for fixed wiring in buildings and for some specialist applications where there is little alternative, such as railways and trams. Since normal
circuit currents in the neutral conductor can lead to objectionable or dangerous differences between local earth potential and the neutral, and to protect against
neutral breakages, special precautions such as frequent rodding down to earth (multiple ground rod connections), use of cables where the combined neutral and
earth completely surrounds the phase conductor(s), and thicker than normal equipotential bonding must be considered to ensure the system
is safe.
Shared neutral
A shared neutral is a connection in which a plurality of circuits use the same neutral connection, This is also known as a common neutral, and the circuits and
neutral together are sometimes referred to as an Edison circuit.
Single phasg
Main article; Split -phase electric power In split phase wiring, for example, a duplex receptacle in a kitchen, devices may be connected with a cable that has three
conductors, in addition to ground. The three conductors are usually coloured red, black, and white. The white serves as a common neutral, while the red and black
each feed, separately, the top and bottom hot sides of the receptacle. Typically such receptacles are supplied from two circuit breakers in which the handles of two
poles are tied together for a common trip. If two large appliances are used at once, current passes through both acid the neutral only carries the difference in
current. The advantage is that only three wires are required to serve these loads, instead of four. If one kitchen appliance overloads the circuit, the other side of the
duplex receptacle will be shut off as well. This is called a muitiwire circuit. Common trip is always required if there are loads that use more than one phase
simultaneously. The common trip prevents overloading of the shared neutral if one device draws more than rated current.
