Rezistenta electrica boiler 2 in 1 pentru sistem solar si retea
Incalzeste apa folosind energie solara DC 48V sau alimentare de la retea AC 220V, intr-un singur dispozitiv. Solutia ideala pentru reducerea costurilor cu energia si valorificarea panourilor fotovoltaice existente. Compatibila cu majoritatea boilerelor standard, asigura continuitate in furnizarea apei calde indiferent de conditiile meteo.
Ce obtii cu acest produs
- Economii la factura de energie prin prioritizarea automata a sursei solare DC 48V de 500W
- Functionare neintrerupta asigurata prin alimentarea backup de la retea AC 220V de 1000W
- Protectie completa impotriva supraincalzirii cu 2 termostate de siguranta calibrate la 85 grade
- Instalare simpla in boilerul existent fara modificari majore ale instalatiei sanitare
- Compatibilitate cu sisteme fotovoltaice off-grid si on-grid pentru maxima flexibilitate
- Constructie robusta cu garnitura de silicon si cabluri de conectare prelungite pentru montaj usor
Cum functioneaza si cum se instaleaza
Rezistenta dispune de doua circuite independente: unul conectat la sistemul solar DC 48V care functioneaza prioritar ziua, si unul conectat la reteaua AC 220V care preia automat sarcina cand energia solara nu este suficienta. Termostatele integrate opresc automat incalzirea la 85 de grade pentru siguranta maxima.
Instalarea se realizeaza prin inlocuirea rezistentei vechi din boiler, conectarea cablurilor marcate distinct pentru DC si AC, si testarea functionalitatii ambelor surse. Nu necesita competente avansate de electricitate, doar respectarea polaritatii pentru conexiunea DC si a fazei pentru AC.
Intrebari frecvente
Pot folosi aceasta rezistenta cu panouri solare de 12V sau 24V?
Nu, rezistenta este proiectata strict pentru sisteme DC 48V. Pentru alte tensiuni, veti avea nevoie de un convertor DC-DC adecvat sau de o rezistenta compatibila cu tensiunea sistemului vostru.
Cat timp dureaza pana incalzeste un boiler de 100 litri?
Cu alimentare solara DC 500W, aproximativ 4-5 ore pentru temperatura de 60 de grade. Cu alimentarea de la retea AC 1000W, timpul se reduce la jumatate, circa 2-2.5 ore, in functie de temperatura initiala a apei.
Ce se intampla daca ambele surse sunt conectate simultan?
Rezistenta functioneaza corect cu ambele surse conectate permanent. Sistemul va utiliza prioritar energia solara disponibila, iar reteaua AC va completa sau prelua sarcina cand este necesar, fara risc de suprasolicitare.

Inspired to create a chair where the back and arms are moulded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.

Inspired to create a chair where the back
Made entirely of oak, the Bow Chair is comfortable, visually pleasing and brimming with character. The moulded plywood seat is unusually wide in proportion to its depth and a waterfall edge at the front softens contact with the hamstrings.
