Wellsee solar inverter wiring

 
A set of basic PV system include solar controller, solar PV, solar inverter, and batteries. Solar panels are made of crystalline silicon cells. Solar panels come in various sizes to provide a full range of application requirements. The most severe environmental conditions to protect the cells, solar panel, high transfer rate and low iron tempered glass are made of, anti-aging ingredients encapsulating, lamination insulation back by high resistant and warm climate of anodized aluminum, sheet box. Solar panel frame and fork, reliable, virtually maintenance-free diets are designed to work efficiently in sunlight. Solar panel mostly used as PV system installation.
 
PV solar panel roof Systems, PV stations, can be used in manufacturing, and other power generation applications, etc.Mechanical and electrical installation of the solar system should be conducted according to all applicable electrical codes encrypted, encrypted construction and electrical interconnection requirements included.
 
Requirements may vary with the electrical system, and DC or AC application.
 
Mounting solar panel installation site. Solar panels can be used on land area, except for sulfur and corrosive salt field.
 
Excluded uses include, but are not limited to, solar panel installations will come into contact with salt water or fresh or salt water completely or partially, is an example of the boats, docks and buoys used to is likely to include the possibility of being submerged. Not a place where the module will be immersed in the water or sprinkler system or sprinkler, etc. to establish continuous contact with water. Module a maximum design pressure of 50 pounds per square foot, 2400Pa about, which under certain circumstances around 130 km / h is consistent with a slight wind speeds are designed for.
 
Actual maximum allowable wind speed module type configuration space, and other factors are growing, can be affected. Under no circumstances shall more than 50 pounds per square foot module an evenly distributed air pressure, snow, or other fees are subject to.
 
Open flames or flammable materials near the solar do not install.
 
When choosing a site, trees, buildings, or to avoid obstacles. Modules for direct exposure to sunlight should be installed in order to maximize and to eliminate or at least followed. In partial shade too much modules and systems can reduce production. In addition, a partial shade internal temperature hatched area, which can reduce unit production is low and life progress.

The value of solar installations
Modules, each of the vertical can be placed on the corner in a horizontal orientation. Correct certain tilt and azimuth orientation for maximum exposure to sunlight should be used.
 
Solar panel tilt angle
Most solar power, either directly aimed at producing solar installations where solar panels are mounted on a permanent structure, entitled to solar panels for optimum performance for the winter. As a rule, if the PV system is generating enough in the winter. Satisfactory for the rest of the year. Solar panels and solar panel angle between the ground is measured.
 
Wrong set of modules will result in loss of power orientation. The same angle and orientation module must be installed in series. Different orientation or angle, loss of power module to the amount of sunlight can cause differences.
 
In the northern hemisphere, solar panels should face south, and in the southern hemisphere, solar panels should face north.


Fixing in the solar panel support structure attached to the growing use. Solar panels at the back of the frame through the hole to be screwed into supporting structures alone flanges. Nuts, washers, rings, and locks with stainless steel bolts, is recommended for module assembly. Make extra holes for mounting and not recommended will void warranty. Ends being equipped with solar panels should not be.
 
Class structure and ice rising air pressure, etc. The support structure for installation, use good materials and corrosive forces would face treatment.
 
Installation of solar panels should be proper ventilation. 4.5 inches (115mm) about solar panels or more down for clearance of air circulation and allow cooler solar panel is recommended. Elevated low-voltage and power, solar panels and small life temperature. 1 / 4 inch (6.35 mm) or more clearance between the solar panel needs to thermal expansion of the frame.
 
1) blocking diode
 
Barrier diodes can avoid overnight battery discharge causes the solar array output to prevent damage and damaged or destroyed by the reverse flow.
 
Barrier diode or possible energy for each solar panel solar panels, solar panels or via a chain to prevent backflow of wire in parallel with the series should be installed when used in combination with wire or a battery.

2) Over current protection
Where necessary to meet local codes and system voltage for the maximum number of modules a fuse or circuit breaker, fuse to use.
Always protect the fuse on the battery connection. Solar plate for fuse size (solar) refer to. Also charge controller manual for details.
All electrical appliances must equal or more ratings of the rating system. Not exceed the maximum system voltage of solar panels as stated on the label.
 
3 grounding)
All solar panel frame for security should be based. Support structure mechanically ground until they are connected to the solar panel should be based on the bolt.
 
A self-tapping grounding screw holes on the frame with a solar panel to a separate ground wire attached. Solar panel frame with grounding holes is provided. Nuts, washers, rings, and locks with a stainless steel bolt, modules are recommended for grounding. Earth wire electrical conductors as at least the same size should be larger than 10AWG ground wire recommended.
Solar 4 stars)

Install solar panels are factory-equipped with wires and shortcuts. Modules are designed to be easily interconnected in series.
A solar panel cable and electrical connections, which pre-wired for the male and female waterproof distributor has a couple of connectors. Cable Positive and negative are a clear mark.
 
These cables connectors at the other end firmly with ease in an adjacent solar panel solar panel male connector to female connector to the connector is protected by the adjacent solar modules can be daisy chain.
 
A series of electrical connections are positive (+), the first solar panel to the negative terminal should – solar panel terminals (). A parallel electrical connections are positive (+), solar panel’s positive terminal (+) to be the first solar panel terminals.
 
Cable typically 14AWG (2.5MM2) wire gauge should be beaten to the solar panel or a solid copper conductor type, nominal sun-resistant, solar panels and solar panel exposed to the weather wire, 12AWG (4.0mm2) used with each other .
 
The maximum and minimum diameter cable connector cable can be used with the 8mm and 6mm respectively. Return a different string or strings of series of modules may be required for positive and negative end can be loaded to run. Male and / or former stars return to the female connectors wired connection and / or source termination circuit box in the string can be eliminated. Solar Bypass (s) diode is installed.
 
 
How to maintain the solar panels?
 
A remote site to investigate this unusual, but once a year. In most cases, normal rainfall is enough to clean the solar panel glass.
A mild soap and water to clean glass with a soft cloth. Solar panels that are moving Fiat (0 ° tilt andle) should be cleaned more often because they do not clean themselves as efficient solar panels that will put on a 15 ° inclination or higher.
 
It is recommended that periodic monitoring of solar panels for damage to enforce glass, back skin, frame and support structure. Loose connections and check the electrical connections for corrosion. Check the mounting support structure and modules are loose. Cable connectors, and check the grounding connections. Changes like solar panels and type, if necessary should be. Solar panels work effectively without ever being washed, although the removal of dirt from the glass front can increase production. Glass, a wet sponge or cloth, wear rubber gloves for electrical insulation can be washed with.
 
Solar protection
 
Solar panel installation and operation must be performed by qualified personnel. Children should not be allowed to the solar power system.
To avoid electrical hazards when installing, wiring, operation and maintenance modules. Solar panels to produce DC electricity when exposed to light and thus produce an electric shock or be burned. Solar panels power an electrical circuit or to load even when not connected to the production. Solar power as little as 5% of full sun to produce near-perfect performance to both present and increase the intensity of electric lights. Do not touch parts of cables and connectors. As an extra precaution, use insulated tools and rubber gloves when working with sunlight, the solar panels are.
Fall from high place solar panels death, injury or damage will result. Solar or heavy objects falling on the solar panel, never leave a solar panel is not supported or are not vulnerable. If a module should fail, broken glass, repair broken glass with a solar panel can not be and should not be.
When installing or solar panels or wiring modules with opaque material to face completely covered to prevent the production of electricity are dealing with. Solar / off switch is on. Solar panels generate electricity when exposed to sunlight and are dangerous, they can be solar sunlight, or in front of full coverage of an opaque cloth, cardboard or other opaque material to completely remove with disabled, or by solar panels with a smooth, flat surface to work down to install or maintain.
 
Not artificially concentrate sunlight on solar panels.
 
Solar panel is more than nominal specifications. Industry-standard ratings 1000W / ㎡ and the terms of the cell temperature is 25 ℃. Reflection from snow or water in the sun rise and can thus stimulating current and power. Also, colder temperatures much stress and increase strength.
Terrestrial solar panel is intended for use only in applications, thus the use of aerospace or marine environments or shine except in concentration.
It is recommended that the solar panel installation in the box until the time is filled.
 
Work with only one solar panel and dry equipment under dry conditions, as where flammable gases install solar panels or vapors may be present not produce sparks.
 
Drill holes in the frame of the solar panel as it will void the warranty do not. Solar frame construction eaten as it will void the warranty.
With care, the front glass is broken or if the polymer skin is back, Tom, each module or frame contact with the surface can produce an electric shock. Especially when wet modules, broken or damaged modules must be removed. Do not disassemble, bend, impact by sharp objects, walking on, and / or drop, etc. to throw foreign objects always free surface. Avoid sharp edges.
 
Using solar panels intended to function only follows all the solar panel manufacturer’s instructions. Remove module, or remove any part or label established by the manufacturer. With no paint or glue to treat the back of solar panel.
 
Unless otherwise stated, it is recommended that the latest local, national or regional electrical code requirements are followed.
Put the Installation Guide for future reference.
 
Notes
  • Electrical characteristics standard test conditions (100 ㎝ / 2 MW, AM 1.5 spectrum, and 25 ℃ (77 ° F) under a room temperature radiation ISC VOC, and Pmax indicates the value is within ± 5 percent.
  • Under normal conditions, a photovoltaic solar panel that is more current and / or voltage of the standard test conditions to report on the status of construction is expected to experience. As a result, ISC and VOC values ​​a factor of 1.25 this module is to identify the component voltage electrical conductor ampacities, fuse, shape and PV Linked to production must be multiplied to determine the size of the control.
