Your Solis, planned every half hour.
Orza reads your Solis through SolisCloud, with an API ID from your own account, and decides what the battery should do each half hour from your tariff’s prices, your roof’s sun and how your home uses power. Every decision comes with its reason.
Connected with your SolisCloud API ID. Nothing to install.
Orza reaches your Solis through SolisCloud, as the SolisCloud app does. No hub, no box and nothing on your home network.
- Ask Solis to switch API access onRaise an “API Access Request” ticket at solis-service.solisinverters.com, giving the email address you use for SolisCloud. It can take a few days.
- Activate it in SolisCloudLog in at soliscloud.com, open Account, Basic Settings, then API Management. Activate it, and copy your API ID and API Secret.
- Paste them into OrzaThey are encrypted before they are stored. If the account holds more than one inverter, you choose which. Then check the first reading against the SolisCloud app.
- Tell it the restYour battery’s size and your panels, which Orza does not read from Solis, then your supplier. The first plan follows soon after.
What Orza reads from SolisCloud, and nothing made up.
Every figure Orza shows about your battery comes from SolisCloud or from you. This is what it reads.
- Every five minutesSolar, home use, the grid, battery power and the battery’s charge level. SolisCloud itself updates every five minutes.
- The last four weeksRead back when you connect, so Orza knows how your home uses power from the first day, not after weeks of learning it.
- What you tell itThe battery’s size and your panels. Orza does not read them from Solis, so setup asks.
- What Orza does not readBattery temperature and state of health. Orza shows them as not reported. It never fills them in.
A plan for the next 36 hours, remade every half hour.
Orza works out a schedule for your Solis: when it should charge, hold its charge and run the house, across every half hour it can see at once. Each decision comes with the reason beside it, and Savings shows what the plan would have cost against what your battery really did.
See the app, page by pageWhat the plan is made from
- Your tariff’s pricesOctopus connects with an API key, so your tariff’s prices arrive by themselves, half-hourly ones such as Agile’s included. For British Gas, OVO, E.ON Next, EDF and ScottishPower you enter your tariff.
- Your roof’s sunWhat your roof really made at the same times over the last few days, checked against the forecast.
- Your homeHow much the home uses and when it is busiest, learned from its own readings.
- Your battery’s lossesEvery kWh that goes through the battery loses a little on the way. The plan pays for that loss, so it only moves energy through the battery when the price difference covers it.
Start by watching. Hand over when you’re ready.
Every home starts in Monitor only, so you can see what Orza would have done with your Solis before it does anything.
- Monitor onlyRead-only. Orza works out what its plan would have saved and sends nothing.
- AssistedOrza’s plan as advice every half hour. You decide what the battery does.
- Automatic controlOrza sends its plan to your battery through SolisCloud. Hand control back any time.
- PausedOrza stops planning, and your battery follows its own settings.
Before you connect your Solis.
The short answers. The technical FAQ covers how the connection works, how the plan is built and how the saving is scored.
Read the technical FAQDoes Orza replace the SolisCloud app?
No. Keep it for warranty registration, firmware updates and safety alerts. Orza sits alongside it as the plan, reaching your system through the same cloud the SolisCloud app uses.
Is Orza a smart scheduler for my Solis?
Yes. Every half hour Orza works out a schedule for your Solis: when to charge from the grid, when to hold and when to run the house, from your tariff’s prices, the forecast for your roof and how your home uses power. It gives the reason for each half hour, and remakes the schedule when new prices are published.
Why do I have to raise a ticket with Solis first?
Solis switches API access on for each owner by request. Until it has, there is no API Management page in your SolisCloud account to get an API ID from. The ticket is called an “API Access Request”, and Solis can take a few days to answer it.
Which Solis systems does it work with?
The inverters your SolisCloud account can see once API access is on. If there is more than one, you choose which. The first reading has to add up before anything is stored, and Orza shows it to you to check against the SolisCloud app.
Which tariffs does it plan around?
Octopus, British Gas, OVO, E.ON Next, EDF and ScottishPower tariffs, including dynamic and time of use tariffs for import and export. A plan is worth most on a dynamic tariff such as Octopus Agile, where the price changes every half hour.
What happens if my internet or SolisCloud goes down?
Your battery carries on under its own settings. Orza is never in the power path. The half hours it couldn’t read are shown as missing, and left out of your savings rather than guessed.
What does it cost?
