6 FAQs about [Photovoltaic inverter programming]

What is a solar inverter API?

Data on real time and historical production can be access via the Solar Inverter API. What is an API? Well, an Application Programming Interface (API) is a way for computers to access data from another computer. So the Solar inverter API is made to allow for sharing of the solar data to external systems.

How can solar inverter data be combined with EV API?

The solar inverter data coming from the API can also be combined with e.g. EV API to build more advanced use cases. The best example is solar smart charging of EVs, where the end-user can automatically charge their EV when they have excess solar production. This optimizes for renewable energy supply and reduces the strain on the grid. Win, win!

What data does a solar inverter collect?

The data produced by your solar inverter is your personal data, and it is up to you if you want to link this data source to other systems. Maybe you want your utility to automatically collect your renewable energy production for local incentives or have your EV automatically charge when you are producing excess solar.

How does a solar inverter work?

The solar inverter usually shares some basic info about itself via the API. This includes brand, model, capacity and other basic data to identify the inverter as your own. Most importantly the inverter API shares the real-time production of solar energy. Usually presented in kW. The data resolution varies from updates every second to every minute.

What is the control design of a grid connected inverter?

The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.

How does a PV inverter state machine work?

The inverter state machine then sequences to checking for DC voltage. To feed current into the grid the DC voltage (which in case of PV inverters is provided from the panel or panel plus some conditioning circuit), it must be greater than the peak of the AC voltage connected at the output of the inverter.
