How To Select Rooftop Solar Inverter For Your Farm

For many farmers, installing rooftop solar system is one of the best choice to getting rid of the unstable power electricity, reducing the loss of sudden power cut. However, there are amounts of inverter brands on the market. How to choose the best one to the farms? Keep reading.

Having a solar system is one of the major investment for most farmers. They don’t have a big budget. They prefer to have one durable inverter with lower prices.

Thus, the costs are the first thing to be considered,

1. Costs of installment

There are 2 types of inverter, string inverter and micro inverter. When choosing solar inverter for rooftop solar, the string inverter is the best type. Why? Because string inverters are easy to install and remove as its advantages of light weight and compact size. No additional professional equipment and tools are needed. Thus, the costs of installing string inverter is lower than micro-inverters.

2. Costs of Inverter

Solar inverter is composed of many components, such as IGBT, fuses, capacitors, sensors, etc. Different brands of theses components differ larger. Pay attention to the following when buying the inverter

Efficiency

The high efficiency of the inverter is the basic guarantee for rooftop solar. The difference in efficiency between different brands of inverters is mainly due to system optimization and line loss. For string inverters commonly used in user systems, each battery string is input to an inverter, and the inverter performs MPPT on the input battery strings individually to ensure that each string generates the maximum power. Even if one string is disconnected due to insufficient solar radiation or failure, other strings will not be affected and continue to generate power normally.

Certification

Regardless of whether inverters are exported abroad or sold domestically, the country has strict standards for them.You can use this as a reference when choosing. .

In addition, the National Quality Inspection Center conducts random inspections of different batches of inverter products from domestic inverter manufacturers every year and publishes the results. If you can't even pass the random inspections of the national quality inspection department, how dare you say that the inverter is reliable? Of? You can also use this as a reference when choosing.
