Read the state of charge history on the PCU
30-day state of charge at a glance: which curve shape indicates a negative energy balance, which indicates a forgotten consumer — and what the graph does not show.

PCU or classic battery monitor: when each makes sense
Not every system requires a central unit. Deciding based on panel area, wiring effort, operation, and expandability — when a battery monitor suffices and when the PCU pays off.
Control devices via CI and CAN bus on the PCU
What runs via the bus and what remains a separate circuit. How CI and CAN bus operate on the PCU, why a bus is laid out and terminated as a...
Battery values at the PCU: capacity, state of charge, starter battery
The state of charge is calculated, not measured. Which values must be correct for this, how the starter battery is integrated, and why the display drifts without regular full charging.
Setting up tanks on the PCU: Sensor type, volume, characteristic curve
Enter the usable volume, not the nominal volume — otherwise the PCU will show full even though nothing more is coming. Determine the sensor type, compensate for the characteristic curve...
Wiring the Connect Hub: which sensor goes where
The Connect Hub bundles all sensors and routes a single cable to the display. Where it is positioned, and the order in which the shunt, batteries, and tanks are connected—complete...
