No, export limiting functionality is not yet compliant with RD 244/2019. Most installations with Enphase microinverters are residential scale (below 15kW) and are easily accepted without this compliance.
Each microinverter is a single phase device. Three-phase installations are constructed with single phase microinverters distributed across the phases. The inverter will monitor power consumption at each phase using the CTs connected to the Envoy-S communications gateway, limiting grid export to the defined level, either on a per phase or aggregate basis as required.In three-phase installations, can you divide surpluses by phases?
There are a number of methods but often cell customers use a soldering iron. Also we have an instruction guide that explains how to connect the cell and tabs so feel free to contact us from the inquiry page.
SunPower® Performance solar panels use high efficiency mono PERC cells, while Maxeon panels use SunPower's proprietary back contact technology developed for our Maxeon panels.
