takze to bude zrat len pri nejakom zvode, ak je spirala ok Tak by k nicomu
nemalo dochadzat.. nie? Mam na mysli taku tu spiralu co je v trubke keramika a v
tom odporovy drot. <o:p></o:p></SPAN></P>

este by som sa spytal, Je zcestna taka myslienka ze by spirala bola nahradena
tranzistormi ktore by ohrievali vodu? Ta regulacia MPPT by sa dala takto
jednoduchsie realizovat (skoro bez strat) potom.<o:p></o:p></SPAN></P>
