Solar module connections
DANGER
Risk of death due to electrical shock and discharge!
The PV generators/cables may be live as soon as they are exposed to light.
WARNING
Serious burns due to arcs on the DC side!
During operation, dangerous arcs can occur when pulling or plugging the DC connections.
Before connecting the DC connectors, de-energise the DC side. DC switches must be in the OFF position.
WARNING
Risk of fire due to improper installation!
Incorrectly fitted plugs and sockets may heat up and cause a fire.
During installation, be sure to follow the manufacturer's requirements and manual. Properly mount plugs and sockets.
Please note the following points before connecting the PV modules:
- Our planning tool KOSTAL Solar Plan should be used to optimally configure the solar modules and achieve the highest possible yields.
- Check the planning and the wiring of the modules for plausibility.
- Measure and record the DC idling voltage and polarity of the PV modules. The idling voltage of the PV modules must be in the voltage range between UDCstart and UDCmax.
PIKO CI | UDCStart | UDCmax |
|---|---|---|
30 | ≥ 250 V | ≤ 1000 V |
50/60 | ≥ 250 V | ≤ 1000 V |
- Make sure that the maximum short-circuit current of the PV modules is less than the permitted value.
- Make sure that the PV modules are not short-circuited.
- Make sure that the inverter is closed when the PV modules are connected.
- Make sure that when connecting several inverters there is no cross-connection of the PV modules.
Failure to observe these requirements will render any warranty, guarantee or other liability offered by the manufacturer null and void.
