balkonsolarPeople in the #UnitedKingdom are all hyped up because the Government promised to legalise #pluginsolar (was it ever illegal?) - so before you rush to #LIDL & #Amazon - of all places - to buy #pluginpv please follow this guide from ze German NGO that helped to bring 4 Mio systems to Germany.
About 1,1 Mio systems are registered but for the consumer there is little benefit in registering, so market studies and our own research suggest take it x4 = ca 4 Mio systems. About ½ have a battery.
Usually these system consist of:
1 -4 solar panels
a microinverter
AC cable
DC cable
and mounting.
While the sun shines on the #solar panels and the micro inverter senses a grid (!) they push electricity via a standard plug and socket into your house and your devices use them.
This is safe if you stay below certain thresholds. In Germany VDE thinks not more than 800 W over a standard #Schuko Socket and not more than 960 WattPeak systems.
This is fairly conservative and designed with the oldest wires in mind, e.g. the 15% immediate post war 2-wire systems and not more modern 3-wire house installations.
We believe up to 2 kWp is usually safe.
