“Just take a look” visits
The client calls because something feels off, and you drive over to see it works.
Barnex for installers
Your client gets solar-surplus control with no subscription, you make fewer service calls and earn on equipment and installation. Here are the terms, tools with their readiness status and the request form.
Free unit for selected installers: 5 left.
What eats your time after the install
A call when it is too late
You hear about a flat battery or an outage from the client, not from the system.
Inverter cloud lags
Official portals refresh every few minutes, but you need to diagnose now.
Post-install setup
Modes, tariff schedule, Smart Load: hours of work that rarely get paid.
What you offer the client
All of it works with no subscription, for good:
- Solar surplus goes to the boiler and EV charging, not to the grid
- Main breaker protection against tripping under heavy load
- A “how long will the battery last” card during an outage
- Telegram alerts: power lost, power back, outage summary
- Phone control and a local interface that needs no cloud
Tools for you
An honest status for each function: what works, what is in pilot, what is ahead.
Client portal with history
Live state, charts and 30 days of history; clients see it themselves and call less.
Fault list across your sites
See who has a problem before they call.
Site list with status
One screen: who is fine, who needs attention, who is offline.
Commissioning act
An on-site checklist and a PDF act for the client: fewer disputes after the install.
“Report a problem” button
On the device and in the portal. You write, we fix and reply.
Remote settings with a change log
Change modes without a visit; every change is logged and reversible.
History for warranty cases
A PDF report for a period: outages, alerts, setting changes.
“Opportunities” tab
Shows where a client's system lacks battery or a boiler: a reason for a new offer.
Commission on client subscription
20–30% of the paid Plus subscription once it exists (terms to be confirmed).

You set the price of your work. We do not regulate it.

Diagnose from the site list and answer the client from the portal instead of driving out.

Questions
Which inverters does it work with?
Deye is the most thoroughly tested; Growatt and Victron are supported, others are added with a JSON map. See the Compatibility page.
Does the client pay a subscription?
No. Everything available today works with no subscription, for good. New paid functions may appear later, but we will not close what already exists.
Whose data is it?
The client's. You see the sites you installed, and the client can revoke your access in the portal.
What if something does not work?
Press “Report a problem” on the device or in the portal. We do the fixing.
Is internet required?
Basic functions work locally. The portal, Telegram and tariffs need internet.
How do I order for clients?
Send a request: after a short call we agree on quantity and shipping.
Installer request
Devices are in stock and ship after the order is confirmed. Features are being finalised, so details may be refined.
