pace9 - inverters

We derived pleasure from our customer’s happiness. The possibility of having the right inverter to meet individual customer’s Solar power need is our pride.
It’s unfortunate that most consumers do not have the right information from our competitors when it comes to installing solar power system for their domestic consumption.
Inverter is one of the vital parts of solar power system, though, it depend on the solar system required for the energy need.
Here in pace9, we design, build and install any solar power system, when taking specifications for consideration for solar system project, we have our three basic classifications of inverters if there’s need – Battery Backup Inverter, Stand-alone Inverter and Grid-tie Inverter.
Yes, before we go further in our almighty inverters, lets chat a little bit about it… (Solar Powered Inverters) Solar Powered Inverters have special functions adapted for use with photovoltaic arrays. The critical balance of system component in a photovoltaic system allows the use of electrical household AC powered equipments, like the TVs Fridges, Fans, etc…
Our harvested energy from the sun by solar panel is variable low voltage direct current (DC) while our alternating current (AC) is high voltage.
Today, most of our electrical equipment and appliances are AC, then, how can we change the harvested DC to AC uses. This tells us that we now have two energy to deal with.
To understand what we are dealing with, let’s first check out alternator – An alternator would have a coil of wire with a rotating magnet close to it. As one pole of the magnet approaches the coil, a current will be produced in the coil. This current will grow to a maximum as the magnet passes close to the coil, dying down as the magnetic pole moves further away. However when the opposite pole of the magnet approaches the coil, the current induced in the coil will flow in the opposite direction as we all know, as this process is repeated by the continual rotation of the magnet, an alternating current is produced. 
What about transformer? A transformer also causes an electric current to be induced in a coil, but this time, the changing magnetic field is produced by another coil having an alternating current flowing through it. Any coil with an electric current flowing through it will act like a magnet and produce a magnetic field. If the direction of the current changes then the polarity of the field changes.
The difference about transformer is that, the voltage produced in the secondary coil is not necessarily the same as that applied to the primary coil. If the secondary coil is twice the size of the primary coil, the secondary voltage will be twice that of the voltage applied to the primary coil. We can effectively produce whatever voltage we want by varying the size of the coils. 
This simple narratives tells that our inverters are coils, the amount of energy we need depend the size of coil required.
If we connected a direct current from a battery to the primary coil it would not induce a current in the secondary as the magnetic field would not be changing.
However, if we can make that direct current effectively change direction repeatedly by the use of a basic inverter, it would produce a square wave output as the current would be changing direction suddenly.
Some inverter would use transistors to switch the current, the switching transistors switches small current, (most likely DC) which is then convert by further transistor circuitry to bigger current (most likely AC)
A Solar Inverter or PV Inverter, converts the variable direct current (DC) output of a photovoltaic, PV solar panel into a utility frequency alternating curren (AC) that can be use for commercial electrical grid or off – grid consumption.
Battery backup inverters, are special inverters which are designed to draw energy from a battery, manage the battery charge via an onboard charger, and export excess energy to the utility grid. These inverters are capable of supplying AC energy to selected loads during a utility outage, and are required to have anti-islanding protection.
Stand-alone inverters, used in isolated systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral battery chargers to replenish the battery from an AC source, when available. Normally these do not interface in any way with the utility grid, and as such, are not required to have anti-islanding protection.
Grid-tie inverters, which match phase with a utility-supplied sine wave. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages.
Don’t forget, let us know your energy need we will provide you with best inverter specification.
