See your Huawei inverter on your iPhone
Cenit · iPhone & iPad · free for your homeCenit reads your Huawei SUN2000 plant through a FusionSolar kiosk link. No password, and no account to make.
Download on the App StoreFusionSolar has everything about your plant, and finding out what you made today takes a few screens. Cenit keeps the everyday part in plain sight. What you're making right now, how today compares to your best days, and what the panels are saving you.
What you need
Just your plant's kiosk link. The kiosk is FusionSolar's public view of a plant. Anyone with the link sees its production and nothing else. They can't see your account or change anything, and there's no password.
How to get the kiosk link
- Sign in to FusionSolar on a computer with the owner's account.
- Open your plant and look for the Kiosk button.
- Turn it on and copy the link it gives you. It's long and has kk= somewhere in it.
No Kiosk button? You're probably in your installer's account. Ask them to give you owner access to your plant.
The link expires after a year. When it does, Cenit asks for a new one. Paste it and your history stays.
How to connect it in Cenit
- Download Cenit and open it. It starts with example data so you can look around.
- Tap Connect my inverter and pick Huawei.
- Paste the link. If someone texted or emailed it to you, you can paste the whole message and Cenit finds the link inside.
- Tap Connect and you're done.
Cenit keeps the link in your iPhone's Keychain and only ever sends it to Huawei's servers. What it reads stays on your phone.
What you see with Huawei
What you're making now, and so far today
Huawei refreshes the kiosk every 30 minutes, so the numbers run up to half an hour behind.
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. That line fills in from the day you connect.
What the panels save you
Tell Cenit what you pay per kWh and what you get for power you send to the grid. It works out roughly what the panels saved you this month and this year, in your own currency. 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 below usual.
What you won't see
The kiosk only shares the total for the whole plant, so there's no panel-by-panel view. Each day's curve is what Cenit managed to read that day. If you last opened it at 1 pm, the curve stops at 1 pm. The day's total still comes out right once Cenit reads the link again the next day.
Cenit and FusionSolar
You don't have to pick one. Cenit doesn't replace FusionSolar.
What Cenit adds
One screen with what matters day to day. Today compared with your last two weeks. A savings number in your currency. Widgets. And no password every time you want to check your plant.
What you still need FusionSolar for
Setting up the plant and the inverter, device alarms, your battery if you have one, each optimizer, and your history from before you connected Cenit. If something is wrong with the inverter, your installer checks it in FusionSolar.
Cenit is an independent app by Hrvoje Matošić, made in Mexico. It isn't made by Huawei and isn't affiliated with Huawei. It reads FusionSolar's public kiosk, so if Huawei changes something on their side, the connection can stop working for a while.
Questions
Is there an app besides FusionSolar to check my Huawei inverter on iPhone?
Yes, Cenit. You paste your plant's kiosk link and see your production, today's curve and what the panels save you. It never asks for your FusionSolar password.
How do I share my FusionSolar plant without giving out my password?
With the kiosk link. Anyone who has it sees your plant's production and nothing else. If you want to stop sharing, turn the kiosk off in FusionSolar and the link stops working.
FusionSolar won't load or won't let me log in. Will Cenit work?
Cenit doesn't log in as you. It reads the kiosk link, which has no login, so a problem with your password doesn't touch it. You do need to sign in once with the owner account to get the link. And if Huawei's servers are down, Cenit can't read them either.
Why can't I see my history from before I connected?
Huawei's kiosk only shows today. Cenit keeps every day from the day you connect the link. Anything older stays in FusionSolar.
How much does it cost?
Nothing for your home. Cenit is free for up to 3 plants. People who watch more, usually installers, pay once or monthly depending on how many. 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.

Cenit also works with NEP, Hoymiles, APsystems, Enphase, SolarEdge, Growatt, Felicity Solar, Fronius, Solis, GoodWe, Victron, Sungrow, Solarman and eGauge meters. They're all on the main Cenit page.
