Hook up solar panels to the grid

Published: 01.09.2017

Sign up using Facebook. My household has a base power consumption of approx. Or you can use 2V traction batteries if you have a need for a very large bank.

Voltage can be a standard 12 volt. Variations on that will cut into the productivity of the system. This is the interface where your solar generated electricity meets the electric meter and allows you to feed electricity back to the grid.

While it is possible to have a solar PV system that is not connected to the National Grid, choosing not to connect means missing out on potentially lucrative incentive schemes like the government's Feed-In Tariff FIT. Also that AC current needs to be synced to the same wave form that is being feed from the grid, another device or sometimes packaged in the inverter. How long will my grid connect solar power system last? Several aspects will need to be evaluated to determine if your home is a good solar site, such as orientation, space available, shadows on the space available and your current electricity usage.

Why should I connect to the grid?

A grid tie inverter cannot provide backup power. Welcome visitor you can login or create an account. This is all going to be very complicated and probably not worth it compared to selling electricity back to the grid with a legit, aboveboard, permitted system. You will need to decide on how many Watts or Kilowatts of panels you need and choose the ones that fit you best.

Also plug-in the inverter to the mains input line of your house electrical. We have bus bars available as well.

You need a dump load for typical permanent magnet wind or hydro turbines that cannot run no load or it will spin out of control. When you are browsing through solar manuals and diagrams, you will notice that many systems also use batteries to store energy.

You will need to decide how much power you need from your inverter, if you are only running a laptop and a couple of small things then you can use a small W inverter, or if you want to run large appliances you want to use larger 3Kw inverter. The current will depend on the maximum intended load to be used. Next, you need to modify the board to switch back to grid power when the panels aren't producing enough power nighttime, cloudy day, high load, etc.

In either case, the company is obligated to take your excess energy.
