The inverter is an essential component of a solar system. Its primary function is to change the variable direct current (DC) output of the panels into alternating current (AC), which is fed into your home to power your appliances.
Inverter technologies have significantly advanced in recent years that, aside from converting DC to AC, they provide more capabilities to ensure that the equipment operates at an optimal level. Some of the new features include data monitoring, utility controls, and system design engineering. One option to consider is to have a hybrid that can have a battery set up at a later time if the additional cost is an issue during installation.
Hybrid inverters are used for storing energy and providing backup power during emergencies. They can also compensate for intermittent or weak grid electricity (and even lack of it).
For residential solar and storage systems, a Fronius single-phase hybrid inverter can simultaneously manage inputs from both panels and a battery bank. It uses meters and software, which is programmed to assess the most efficient use of available energy.
When using hybrid inverters, be sure that the battery bank voltage is compatible with the DC input requirements. There should also be enough solar capacity to supply the load and charge the batteries.
Single Phase or Third Phase
Homes and businesses typically use either single-phase or three-phase inverters. The difference between these systems comes down to the number of wires that are connected to the property. Deciding which one you need depends on your electricity requirements at different times and throughout various seasons of the year. Energy usage may vary from day to night and from summer to winter.
Generally, single-phase inverters are used for residential installations. Meanwhile, the three-phase is commonly seen in commercial buildings.
In addition, you can run single-phase on each stage of the three-phase inverters, although you can’t do it the other way around. But, it should be noted that these two aren’t the only options.
It’s possible to install multiple phases. For instance, a large apartment building may require two or more systems to meet its energy requirements. The electricity they generate will then be divided among the residential units.
Deciding whether a fronius single phase inverter or a three-phase system is right for your property should be done after consultation with your service provider. They have a clear understanding of how much electricity you need.
