FAQ: Multiple micro-inverter installation

I have a microinverter installation with products from ABC Company. I have 2kW installation (8x250Wp). Now I wish to increase my installation with more inverters. My questions:

1) The products from ABC Company use a PLC communication to work with the gateway. Is the YC-500 and YC-500 gateway compatible with the ABC products and the PLC communication?

No, sorry. There is no compatibility of the products from different manufacturers. Each product has its own protocol and the products cannot be managed together.    

2) Can the ABC products and the YC-500 inverters work on the same AC line (same phase)?

Yes, there are many installations where inverters (and microinverters) from various manufacturers work together in the AC 230V grid line (phase). Since the grid requirements are the same for all products, observing these requirements makes all product compatible on the AC line – for the energy production. (Not for the communication protocols).

3) Is the YC-500 gateway needed for the operation of the YC-500 microinverters?

No, the YC-500 gateway is an optional product for monitoring. The microinverters will work without the gateway. Each microinverter is independent, works by itself  and does not need to be controlled from outside.

4) Will not be the PLC communication signals from YC-500 products interfere with the PL communication of the ABC microinverters?

Since the PLC protocols are not public and are proprietary, we do not know any details about possibility of mutual interference on the PLC communication level from various manufacturers. This must be tested for each specific configuration.

5) What is your view of adding more inverters to the existing installation?

We fully support this idea. One of the advantages of the microinverters is that they allow adding more power production to the existing installation without changing the design of the existing installation.
