Replacement of RS485 power-line (NLM) due to interrupted communication
The existing power-line communication is not functioning reliably and/or the plant has been expanded with inverters that do not enable power-line communication.
If required, we can offer to replace the PLM Piggy-Backs in the inverter* with RS485 Piggy-Backs at a charge of € 20.00 per Piggy-Back (excl. value-added tax + shipping).
We must, however, ask that you return the PLM Piggy-Backs that are no longer required.
In return you will receive the corresponding number of RS485 Piggy-Backs as a retrofit kit for your inverter, subject to invoice.
*The prerequisite is that the inverters are compatible with RS485.
