Grid Tie Systems

Grid tied systems
Typically, grid connected PV systems (grid tie systems) are utilized purely for energy cost reduction and selfconsumption of green power. Unutilized power generated by the PV Grid-Tie system may be fed back into the utility network. This avoids green power being lost as may be the case with an Island system, once batteries have been fully charged. This ensures that your PV Grid-Tied system always operates at maximum capacity, yielding the lowest possible cost of generating green power per Kwh. Also, as result of this and the lack of battery storage, PV Grid-Tied systems have the shortest payback periods.

As these systems do not require any batteries, the required maintenance efforts are virtually negligible. PV Grid-Tied systems do not offer backup in case of grid failure. Grid systems can be expanded to AC coupled ESS systems at a later stage.

Smart Grid tied systems

Unlike typical grid connected PV systems that feed power into an electrical grid and may feed excess power back to the utilities, smart grid systems are designed for optimizing self-consumption without any grid feedback. This process is achieved by obtaining daily weather forecasts and shifting manageable loads to matching generation times.

In addition to load management, this system has the ability to throttle back the inverter’s generation to prevent feedback of excess power to the national grid. These systems have online
monitoring capabilities but do require internet connectivity, for daily weather forecasts as well as reporting.

As these systems do not require any batteries, the required maintenance efforts are negligible. Smart Grid PV Systems do not offer backup in case of grid failure. Grid systems can be expanded to AC coupled ESS systems at a later stage.
