Setup guides

Connecting your kit.

One page per device: what you need before you start, where to find it, how long it takes, and what usually goes wrong. Written from actually doing it, not from the manufacturer's marketing.

How far each of these has been proven

Every guide says, at the top, what has actually been tested — because "supported" means different things and you deserve the real one. Where a maker offers a portal, a sandbox or a developer account, it has been used: sign-ins run for real, consent flows completed, responses parsed against faithful simulators of each API with the sign conventions pinned by tests. What that cannot prove is that a particular inverter in a particular garage answers the way its documentation says it will. Tesla and the Sunplug Agent are running on real equipment today; the rest are waiting on their first real one, and the moment somebody's does answer, these pages change to say so.

Solar

Sunplug needs two numbers: what your panels are making, and what your house is using. The difference is what your cars can have. An inverter that only reports production cannot tell surplus from a cloudy day, so those are paired with a meter — each page says which yours is.

Enphase Every few seconds IQ Gateway read on your own network. The best data Sunplug can get from anything. Fronius Every few seconds No account, no key, no subscription — the inverter answers directly. Sungrow One-click sign-in Approve on Sungrow's own page. Nothing to copy, nothing to type. SolarEdge Installer may be needed Site ID and API key. SolarEdge stopped letting owners make their own keys in 2025. SolaX Sixty seconds Generate a token yourself in the SolaX portal. The easiest cloud there is. Solis Coming Waiting on Solis to approve OAuth sign-in, so there will be nothing to type. GoodWe Needs your password GoodWe publish no proper API, so this uses your SEMS account. Read the caveat. Home Assistant Almost any brand If Home Assistant already reads your inverter, so can Sunplug. Shelly meters Grid meter Pairs with an inverter that cannot see your house load. Under a hundred euros. Sunplug Agent Docker · any brand Reads your hardware directly on your own network, instead of asking a cloud what happened ten minutes ago. Runs anywhere Docker does. If it cannot reach your kit, it can send readings from whatever can.

Cars

Tesla All models Straight to the car, including pre-refresh S and X. No wallbox required. Everything else Through the wallbox Any car at all, controlled at the socket rather than through the manufacturer.

Chargers

Controlling the charger rather than the car is what makes the make of your car stop mattering — the limit is applied at the socket. One caveat worth knowing before you start: a charger talks to one service at a time, so pointing it at Sunplug takes it away from its manufacturer's app.

Any OCPP charger Wallbox, Zaptec, ABB, Alfen… Two strings pasted into your charger's own app. Five minutes. go-e No account Local, on by default, one setting. The friendliest charger here by a distance.
