dosta popularan off grid inverter

To je cisti off grid. Znaci trebaju ti i akumulatori. Kada je  
proizvodnje veca od potrosnje puni akumulatore viskom, a kada je obrnuta  
situacija onda iz akumulatora uzima razliku. I taj se ne moze koristiti  
u kombinaciji sa "HEPom" jer nema mogucnosti sinkronizacije mreze.

sinkronizira se...
jer kada nema dosta offgrid, prebacuje na baypass


ali jasno... to je offgrid, kaj sam i napisal

citat s linka:
 .....the typical output power of the GridFree Kit is about 230 Watt.......
Znaci, pretvarac daje max230W, a ostalo se uzima iz mreze...

I dalje po trenutnim propisima nedozvoljeno u Hr.

kad se pogleda
da za dozvolu treba 66 papirov

Taj dio me i zanima - kako to izvesti automatikom :)

Inverter paralelno napajas sa suncanim celijama i dc napajanjem.
Recimo imas 24v solarni sistem, nabavis dc napajanje 230/24V dc
i spojis paralelno na inverter.
Zato jer je napon celije veci od napona dc napajanja, i inverter ne trosi  
struju
iz dc napajanja odnosno mreze.
Ovisno o tomu imas ili ne akumulator u sistemu, u principu bolje da ga  
nemas,
ovisi kako i gdje spojit.
Ako akica nema, dc napajanje doslovce mozes spojit u paralelu celijama,
a ako bas oces odvajanje, onda jednom diodom odvojis celije, druga dioda vec  
je u napajanju.
Napon dc napajanja sa 24 spustis na 20-22V na koliko jos uvijek radi u redu  
inverter, da sto
vise energije vuce iz celije.
U slucaju slabijeg sunca, iz mreze ce se uzimat samo razlika koju celija ne  
moze dat,
a ne sve, isto tako i kad je potrosnja veca nego sto celija uopce moze dat.

Da moras koristiti jos skuplje rjesenje. Akumulatori, punjac  
akumulatora, ...
Ako ne koristis on grid inverter, kako sinkroniziras mreze kada ti je  
potrosnja veca od proizvodnje i zelis nadoknaditi iz mreze?

Re: Elektricno brojilo kWh?

DC napajanjem.
Dok je napon celije je veci od napona dc napajanja, nema potrosnje iz mreze.
Dakle, nema akica, nema grida, nema ne dopustenog.

Ovisi o trenutnom raspolozenju "nadleznih". Uglavnom koliko znam za sada  
su kaznu dobili samo oni koji su se bunili na takvo postupanje (i dobili  
upozorenje da iskljuce solar ili da ce ih iskljuciti sa mreze)

Tada je izmedju njihove i tvoje instalacije ispravljac 230Vac/24Vdc....

Ili moja ideja s posebnom  310Vdc instalacijom za sva SMPS trosila
( to je kao da trosila rade na UPS-u, valjda nije zabranjeno zakonom!?..lol)
