See your Growatt inverter on your iPhone
with Cenit · iPhone & iPad · free for a homeCenit reads your Growatt inverter with the same username and password as ShinePhone. See what it's making right now, how today compares to your best days, and what the panels are saving you.
Download on the App StoreCenit isn't made by Growatt. It's an independent app that signs in to the same cloud as ShineServer with your own login and keeps what it reads on your phone. You don't make an account with me.
What you need
Your ShinePhone username and password. It's the same account as ShineServer, Growatt's website. Your installer often set it up when they connected the datalogger, so ask them if you don't have it.
Your plant has to show up in ShinePhone already. If there's no data there, Cenit won't see any either.
How to connect it
- Download Cenit and open it. You can look around with example data first if you like.
- Tap Connect my inverter and pick Growatt from the list.
- Type your ShinePhone username and password, and tap Connect.
- If your login has several plants, Cenit asks which one to open. The rest are under Plants.
- That's it. Cenit pulls in the total for each day of roughly the last year, then the curves for the last 90 days.
Does it say Growatt didn't accept the username or password? Try signing in at server.growatt.com in a browser. If it works there, it works in Cenit.
What you see from your Growatt
What it's making now and today
The watts right now and today's kWh, the same numbers Growatt shows. If your plant has more than one inverter, Cenit adds them up. The datalogger uploads every five minutes, and while the app is open Cenit checks every five minutes.
Today against your best days
Drag your finger along today's curve to see what the plant was making at any moment. The dashed line behind it is the most it made at that time of day over the last 14 days. A sunny day that comes in under it means something changed.
What the panels save you
Tell it what you pay per kWh and what you get for power you send to the grid, and it works out about how much the panels saved you this month and this year, in your own currency. In the US it can fill in your state's average price. In Mexico you get your margin before CFE's DAC tariff instead.
Widgets and alerts
Today's numbers on your home screen, and a heads-up when your clear days come in lower than usual.
What you don't see
Growatt reports the total for the whole plant, not each panel. A string inverter has no way to split it. So Cenit can tell you production dropped, but not which panel. To know if it's dust, shade or a fault, wash the panels and see if it comes back.
Cenit and ShinePhone
ShinePhone is Growatt's own app, and some things only happen there. Cenit doesn't replace it for those.
What you still use ShinePhone for
Setting up the datalogger's Wi-Fi, adding an inverter to your account, or changing inverter settings. Cenit only reads. It doesn't change anything on your equipment.
What Cenit adds
A simple screen for today, your curve against your best 14 days, a savings number and widgets. Your history stays on your phone, so you can see it even when Growatt's cloud doesn't answer. And if another home runs a different brand, it fits in the same app.
What it costs
For your home, nothing. Cenit is free for up to 3 plants and has no ads.
If you're an installer watching more plants, you pay by how many, once or by the month. 4 to 10 plants is 9.99 USD once or 0.99 USD a month. 11 to 49 is 39.99 USD or 3.99 USD a month. 50 or more is 74.99 USD or 7.99 USD a month. The first month has every plant open.
Questions
Is there an app besides ShinePhone to see my Growatt inverter on iPhone?
Yes. Cenit signs in with your ShinePhone username and password and shows what your plant is making, your history and your savings. It's free for a home.
ShinePhone won't load or connect. Will Cenit help?
It depends on what's wrong. Cenit reads the same Growatt cloud, so if their server is down it won't get new data either, but your history is still on your phone. If the datalogger lost its Wi-Fi, no app will see new data until you reconnect it in ShinePhone. If the app itself is slow or stuck, Cenit is another way to see your numbers.
Can I see each panel with Growatt?
No. Growatt string inverters report the total for the whole plant. For a panel-by-panel view you need microinverters that report it, like NEP, Hoymiles or APsystems.
Is it safe to give Cenit my ShinePhone password?
Your password is kept in the iOS Keychain and only goes to Growatt's server. Your readings stay on your phone, and you don't make an account with Cenit. The details are in the privacy policy.
Is Cenit made by Growatt?
No. Cenit is an independent app by Hrvoje Matošić, made in Mexico, and isn't connected with Growatt. Growatt doesn't publish an official API, so Cenit talks to the same server as their website. If Growatt changes something on their side, the connection can stop working for a while.
Cenit also works with NEP, Hoymiles, APsystems, Enphase, SolarEdge, Huawei, Felicity Solar, Fronius, Solis, GoodWe, Victron, Sungrow, Solarman and eGauge meters. See everything Cenit does.
