550W Plug&Play System
2 x Solar module 270W with one (!) Micro Inverter (small inverter / inverter module)
Why does that make sense?
-> approx. 50% of the yield per year comes from diffuse light (shade / no direct sun). The majority of the time, a solar system "runs" far below the rated power of the modules and the inverters can process the output of additional modules without loss.
With a nominal power ratio of approx. 50%, the loss is only about 12%, according to a yield calculation with SMA Sunnydesign.
In addition: Self-consumption is highest in the partial load range. With maximum yield you will usually give away electricity to the EW. The additional yield approx. 75%. The surcharge, only about 37%. You save about 300 CHF.
just plug Legal without additional installations into the socket and produce their own electricity. One can extend this equipment at any time and in series.
If they produce their solar power itself! Meet them quite legally the bureaucracy and the current price increases and they preserve the environment!
Until 600W per meter may be fed or connected without authorization and electricians. An earth leakage circuit breaker (FI) is the main condition, but can be integrated / retrofitted into an electrical outlet.
Per phase (Each has 3 phases) could be 600W fed without compromising security. Whether an EW this so accepted must each inquired. Basically, every owner himself is responsible for keeping the business rules of its EW a. We recommend: Ask her EW and her electrician.
Statements larger plug and play equipment to 3500W are allowed (without electricians and approval), are unfortunately wrong. Quote ESTI (Swiss Federal STarkstromInstpektorat): "... for plants> 600 W an electrician has to create with authorization type 7/9 or 14 NIV fixed installation ...."
Stationary means no plug. Further, the cable must be used exclusively for the supply of 600 W. Consumers and sockets would not be allowed.
If the system is greater than 600W, they need an electrician to 2000 CHF costs about £ 500 to install an additional line and hedging to 3.5KW / phase. The financially not worthwhile for small plants.
