Properly configured, a grid tie inverter enables a building to use an alternative power generation system such as solar or wind power without extensive rewiring and without batteries. A grid-tie inverter converts (DC) into an (AC) suitable for injecting into an , at the same voltage and frequency of that power grid. With the electricity company pays for the net power injected into the grid, as recorded by a meter.

Direct Current (DC) electricity from sources such as hydro, wind or solar is passed to an which is. When the grid fails to accept power during a "black out", most can continue to provide courtesy power.

There are 3 ways to add solar battery backup to an existing grid-tie system: AC coupling, DC coupling, or replacing your inverter. Grid-tied inverters need the power grid to operate—they constantly sense grid voltage and frequency and will shut off if it falls out of range. Retrofitting solar systems with new equipment can be tricky because of all the different equipment options and various methods for incorporating energy storage.

Deze onderdelen zijn op te delen in 3 grote groepen: Opbrengst, opslag en verbruik. Er is een verschil tussen een off-grid systeem, en een deels off-grid systeem gekoppeld aan een on-grid systeem (kortweg on-grid systeem genoemd). Stel jezelf eens de volgende vragen: - Wat doet het weer gemiddeld gezien in de seizoenen in jouw regio? - Hoeveel zonuren heb je? - Hoe hard en.
