Grid Connect had the technology expertise and contract manufacturing connections to facilitate a global supply chain and production capabilities for Rollease. Anywhere control of the home environment Home or away, Rollease customers or installers can now control their shades for lighting changes and privacy concerns with IoT connectivity from Grid Connect.
Grid Connect gave Schlage the Wi-Fi connectivity needed to allow their customers to open or lock their doors from anywhere in the world. Meeting production deadlines Keeping schedules on track is a top concern at Schlage, one that Grid Connect was able to meet by giving their internal teams a head start on development.

A grid-connected system allows you to power your home or small business with renewable energy during those periods (daily as well as seasonally) when the sun is shining, the water is running, or the wind is blowing. Any excess electricity you produce is fed back into the grid. When renewable resources are unavailable, electricity from the grid supplies your needs, eliminating the expense of electricity storage devices like batteries.
In addition, power providers (i.e., electric utilities) in most states allow net metering, an arrangement where the excess electricity generated by grid-connected renewable energy systems "turns back" your electricity meter as it is fed back into the grid. If you use more electricity than your system feeds into the grid during a given month, you pay your power provider only for the difference between what you used and what you produced.
Aside from the major small renewable energy system components, you will need to purchase some additional equipment (called "balance-of-system") in order to safely transmit electricity to your loads and comply with your power provider's grid-connection requirements. You may need the following items:
Because grid-connection requirements vary, you or your system supplier/installer should contact your power provider to learn about its specific grid-connection requirements before purchasing any part of your renewable energy system. See our page on balance-of-system equipment requirements for small renewable energy systems.
You will need to contact your power provider directly to learn about its specific requirements. If your power provider does not have an individual assigned to deal with grid-connection requests, try contacting your state utilities commission, state utility consumer advocate group (represents the interests of consumers before state and federal regulators and in the courts), state consumer representation office, or state energy office.
Power providers want to be sure that your system includes safety and power quality components. These components include switches to disconnect your system from the grid in the event of a power surge or power failure (so repairmen are not electrocuted) and power conditioning equipment to ensure that your power exactly matches the voltage and frequency of the electricity flowing through the grid.
When connecting your small renewable energy system to the grid, you will probably need to sign an interconnection agreement with your power provider. In your agreement, power providers may require you to do the following:
In addition to insurance and fees, you may find that your power provider requires a great deal of paperwork before you can move ahead with your system. However, power providers in several states are now moving to streamline the contracting process by simplifying agreements, establishing time limits for processing paper work, and appointing representatives to handle grid-connection inquiries.
With a grid-connected system, when your renewable energy system generates more electricity than you can use at that moment, the electricity goes onto the electric grid for your utility to use elsewhere. The Public Utility Regulatory Policy Act of 1978 (PURPA) requires power providers to purchase excess power from grid-connected small renewable energy systems at a rate equal to what it costs the power provider to produce the power itself. Power providers generally implement this requirement through various metering arrangements. Here are the metering arrangements you are likely to encounter:
It took me some time to figure out how to get the current, power, voltage setup as sensors rather than the default attributes with Tuya Loca with the Arlec Grid connect plug-in sockets. A step by step guide;
I've connected the grid connect app to Google home app however it doesn't appear under the linked services in Google Home. I see the devices (lights) that are on grid connect but home says they are offline and can't access them. All are working fine through grid connect app. Have unlinked and relinked multiple times. They used to work till yesterday.
Since the Grid Connect gear is basically rebranded Tuya by default it expects to use their cloud platform. Your best solution is the re-flash all the devices to ESPhome so there is never any need for an external network connection.
The process of connecting to the high voltage transmission system in England and Wales involves a variety of people and resources. But what can you expect for your project? These pages aim to help you understand the connections journey, with further related information linked below.

The short answer is yes the switch can be wired for power but not connected to a physical light fitting allowing you to control other devices via the app. I've seem a tutorial where this is a work around for a 2 way light switch for smart switches where one is physically connected to the light and the other is powered only and connected by Wi-Fi. When one switch is turned on/off a "Tap-to-Run" turns the other switch on/off at the same time. It would be a similar concept.
you might be able to switch to something like tuya-local (and local tuya). They're used in the home assistant community to control these devices locally. And even if they need initial connection to tuya cloud for setup, you can then block them from the internet.
I am trying to get my multi plus ii, 5k inverter/charger approved for grid connect use in New Zealand. Has anyone been through this process and got approval. if so, where did you find all the information on the specific technical specification for the inverter, that are needed for the application form. thanks
You can install a Tele grid protect relay if it dose'nt pass the lines company requirements, You can install it as a UPS mode to get past the requirments as well. The inverter does still pass the requirments, because the it has not being ratified yet into law, and also the i believe the SANZ are trying to get the this delayed for these inverters.
I have the same inverter connected May last year and used a solar installer to arrange a sparky to connect the AC side, obtain the code of compliance and the electrical inspection. You or your installer need to submit an application for distributed generation to your lines company. Plus you need to let your power company know as they may need to arrange for an import/export meter to be installed if you don't already have one.
Thanks for the info. I'm an electrician but don't have much experience with the grid connect side of solar. I have already installed this system at my place as a personal learning project. I am essentially off-grid but would like to feedback any excess power in the future. Its a DC coupled system, but will be adding pv on my shed with a grid connect inverter connected to my shed sub board, so on the feed out side of the multi. I have looked at the form that needs to be filled out in order to get approval from the lines company. it requests details that don't seem to be readily available on the multi spec sheet. So was hoping to find someone who has gone through this process.

Precise control of the grid-connected current is a challenge in photovoltaic inverter research. Traditional Proportional-Integral (PI) control technology cannot eliminate steady-state error when tracking the sinusoidal signal from the grid, which results in a very high total harmonic distortion in the grid-connected current. A novel PI controller has been developed in this paper, in which the sinusoidal wave is discretized into an N-step input signal that is decided by the control frequency to eliminate the steady state error of the system. The effect of periodical error caused by the dead zone of the power switch and conduction voltage drop can be avoided; the current tracking accuracy and current harmonic content can also be improved. Based on the proposed PI controller, a 700 W photovoltaic grid-connected inverter is developed and validated. The improvement has been demonstrated through experimental results. ff782bc1db
