Grid-Tie Inverter (GTI)

What is the job of a solar inverter? They regulate the voltage and current received from your solar panels. 

Direct current (DC) from your solar panels is converted into alternating current (AC), which is the type of current that is utilized by the majority of electrical appliances.

In addition to this, grid-tie inverters, also known as grid-interactive or synchronous inverters, synchronize the phase and frequency of the current to fit the utility grid (nominally 60Hz).

The output voltage is also adjusted slightly higher than the grid voltage in order for excess electricity to flow outwards to the grid.

Power Meter

Most homeowners will need to replace their current power meter with one that is compatible with net metering. This device, often called a net 

meter or a two-way meter, is capable of measuring power going in both directions, from the grid to your house and vice versa.

You should consult with your local utility company and see what net metering options you have.

In some places, the utility company issues a power meter for free and pay full price for the electricity you generate;

however, this is not always the case.

 

OFF GRID SOLAR SYSTEMS

An off-grid solar system (off-the-grid, standalone) is the obvious alternative to one that is grid-tied.

For homeowners that have access to the grid, off-grid solar systems are usually out of question. Here`s why:

To ensure access to electricity at all times, off-grid solar systems require battery storage and a backup generator

(if you live off-the-grid). On top of this, a battery bank typically needs to be replaced after 10 years. Batteries are complicated,

expensive and decrease overall system efficiency.

Equipment for Off-Grid Solar Systems

Typical off-grid solar systems require the following extra components:

  • Solar Charge Controller
  • Battery Bank
  • DC Disconnect (additional)
  • Off-Grid Inverter
  • Backup Generator (optional)

Equipment for Hybrid Solar Systems

Typical hybrid solar systems are based on the following additional components:

  • Charge Controller
  • Battery Bank
  • DC Disconnect (additional)
  • Battery-Based Grid-Tie Inverter
  • Power Meter
