Schemas for the inspection.
Every installation needs a single-line diagram but nobody likes drawing one. HappDraw sets up the diagram from the order. You check it and adjust it before it goes to the inspection.
From the order, nothing to retype.
Circuits and RCDs numbered for you.
Cables the way the inspector wants to read them.
Less drawing, faster to the inspection
A diagram that comes from the order matches what you sold and installed.
Doesn't start from scratch
Inverters, panels, batteries and charging stations from the order are already on it, with brand, model and serial number. No retyping, no missing serial number.
Changed in seconds
An extra circuit or a different cable? Drag it in and the diagram rearranges itself. What doesn't fit together won't connect.
At the office and on site
Works just as well on a tablet as on your computer. An extra circuit on site? Change the diagram right there.
Always with the file
The diagram lives on the order. When the inspector asks for it, nobody has to search. Need a file? PNG or SVG.

A diagram the inspector reads in one go
Every diagram in the same notation, whoever draws it. What you fill in shows up neatly. Nobody types labels anymore.
The same notation, every time.
Breaker, RCD, cable: the labels write themselves. Your newest electrician's diagram looks like your best one's.
Fewer questions at the inspection.
Type, fire class, cross-section, length and how the cable runs are right there on the diagram.
The maths is done.
The power per string is already on it. Want to add your own details? There is room for them.
Try it yourself
Play with an example installation. Add a charging station or swap a cable, and see how quickly a diagram is done.
