What you learn today
- sb for all panels
- Groups by name
- Check alignment
Tracking ten panels is easy, a hundred too – as long as you do not address each one separately. A large solar field needs exactly two write instructions.
sb for all panels
sb writes to all devices of a type on the data network, without any name:
sb PANEL Horizontal h
sb PANEL Vertical vThat is the fastest way when all panels are built with the same orientation. Dual panels (StructureSolarPanelDual) or reinforced panels have a different prefab hash – they need their own sb.
Groups by name
If panels are built differently, say on a slope or on a wall, they need an offset of their own. Then each group gets a name and its own sbn:
sbn PANEL HASH("Dach") Vertical v
add tmp v SLOPE # slope group 20 degrees different
sbn PANEL HASH("Hang") Vertical tmpMake sure no panel ends up in two groups and no sb overwrites the groups afterwards.
Checking the alignment
Three batch reads tell you everything about the field:
| Read | Batch mode | Shows |
|---|---|---|
Ratio | Minimum | the worst aligned panel |
Charge | Sum | the output of the whole field – Sum is right here |
Ratio | Count | how many panels are on the network |
A panel with a small Ratio while the others are fine is shaded, damaged or built wrong. If Count drops, one was taken down or a cable is gone.
At night all panels have Ratio 0. A “badly aligned” warning may therefore only trigger in daylight – otherwise the field flashes every night.
Count always counts all devices of the type, even with lbn – the name is ignored. It is no good for counting a group.
Exercise
Task
All panels on the network are built the same way and follow the sensor “Sonne” (conversion as yesterday, without parking).
- Track with
sbfor all panels; write nothing without a sensor - Display “Schwaechstes”: smallest
Ratioin percent - Display “Leistung”: sum of
Charge, display “Panels”: count - Flashing light “Ausrichtung” on when a panel is below 50 % in daylight or the sensor is missing
Hints
Hint 1
Without a sensor jump over the tracking: bnan h check and the label check: before the field check.
Hint 2
sb PANEL Horizontal h and sb PANEL Vertical v after the conversion.
Hint 3
Field: lb … Ratio Minimum, lb … Charge Sum, lb … Ratio Count. Warning only with light.
