Types of String Inverter - Which One Suits Your Needs Best?

A string inverter performs just as well, if not better, than its lower-performing low-priced low-voltage inverter model. So when fallen leaves or other shade hinders one panel of your solar panel's operation, each other panel has to operate at a reduced capacity. The ability of each panel to operate separately using mini inverters, though, allows for higher energy production and greater efficiency - particularly when only a small number of panels are in the shadow. With the right configurations, it is now possible to create a 50% savings in energy consumption that can be passed on to your electric company.

Some people refer to DC to AC conversion ratio, which involves the ratio of DC output power to the AC input voltage. This is different from the maximum combined output, which is the maximum allowable output over the span of a single inverter cycle. So when converting from DC to AC, both maximum and minimum achievable power are used. The type of DC-to-AC converter also varies, though. A DC to DC power optimizer increases the DC to AC ratio, while a DC to AC power inverter increases the AC to DC ratio over the span of one inverter cycle.

The amount of energy needed to run your household depends on your average cell phone usage, your household size, your weather condition, and your location in general. To reduce this energy consumption, you can install a series of small String Inverters in your home or business. String Inverters is generally classified into three categories. They are distributed, storage, and demand response. Let us take a closer look at each category.

distributed String Inverter System: These are used to convert the DC input signal into AC. The microinverters are placed in an array on top of your solar panels or on the ground. Microinverters are often attached to the side of solar panels to increase the string inverter's reach. The storage arrays are often placed in remote areas like desert regions where there is enough sun to make solar energy production feasible. With a microinverter series, you can store energy produced during the day and convert it into the AC during the night.

Central Inverter: If you have two or more solar panels connected to each other and to a battery, you can use a series of central-type String Inverter to regulate the voltage supplied to the batteries. The drawback with this type of string inverter is the complexity involved in wiring them all up. A central-type unit uses high-voltage power inverters to convert the DC input signal to the alternating current needed to power the battery. It is highly recommended that you get these types of units hooked up to batteries as the complexity and wires involved in connecting all the parts of the set up are great.

Solar panels need a steady source of direct current (DC). A single inverter is capable of supplying enough DC input for the whole panels. Since you will be using the DC output from the single inverter, it is highly recommended that you use an inverter with minimum required wattage to ensure maximum performance and lifetime of your panels. The single inverter is also capable of powering all the DC appliances that you have installed on your roof. Since this system has an integrated circuitry design, it is safe to operate the system in remote areas like RV's, boats, recreational vehicles, mobile homes and cabin homes.

Multi-voltage power optimizers: These are the most powerful String Inverter power optimizers available in market. These power optimizers are capable of generating more than 120 watts from just one single inverter. To make the most out of your investment and save substantial amount of money, these types of inverters are best suited for AC/DC systems that can be easily set-up on roof top. They are also durable and can withstand extreme climatic conditions.

String Inverter manufacturers offer different types of single or multi-voltage power inverters. The price of the inverter also depends on the size and brand of the device. However, there are several factors that need to be considered before purchasing any type of inverter. The location of the building where the solar panel system will be installed and operated plays a major role. Another important factor that can greatly affect the performance of the inverter is the quality of the manufacturer that produces the device. Most leading brands produce inverters that function effectively and give long-lasting service.
