2. Off-the-grid - Wikipedia

   en.wikipedia.org/wiki/Off-the-grid

   Off-the-grid or off-grid is a characteristic of buildings and a lifestyle [1] designed in an independent manner without reliance on one or more public utilities. The term "off-the-grid" traditionally refers to not being connected to the electrical grid , but can also include other utilities like water, gas, and sewer systems, and can scale from ...

3. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, at the same voltage and frequency of that power grid. Grid-tie inverters are used between local electrical power generators: solar panel , wind turbine , hydro-electric , and the grid.

4. Tesla Powerwall - Wikipedia

   en.wikipedia.org/wiki/Tesla_Powerwall

   A May 2015 article in Forbes magazine calculated that using a Tesla Powerwall 1 model combined with solar panels in a home would cost 30 cents/kWh for electricity if a home remains connected to the grid (the article acknowledges that the Tesla battery could make economic sense in applications that are entirely off-grid). US consumers got ...

5. Solar inverter - Wikipedia

   en.wikipedia.org/wiki/Solar_inverter

   Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...

6. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   A solar inverter is a balance of system (BOS) component of a photovoltaic system and can be used for both grid-connected and off-grid (standalone) systems. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
