Customer:
I want to purchase a Solar MPPT Charger. How do I connect my 30W 12V solar panel and 12V portable battery to it? I need to know how to configure the board with a resistor for current and voltage settings. Do you offer this configuration service, and if so, is there an additional charge?

želim od Vas uzeti artikl : solarni MPPT punjač, kako bih spojio svoj solarni panel 30W(12V) i prijenosnu bateriju(12 V).
Međutim kako treba podesiti s otpornikom pločicu za struju i napon postoji radite li vi tu prilagodbu pločice. Ako radite, naplaćujete li tu uslugu dodatno

Soldered Support:
We can configure the board for you. Your power bank is a 1S battery, which means the current MPPT charger settings are already suitable. Remember to connect directly to the battery itself.

hvala na javljanju!
Možemo Vam podesiti pločicu, molim Vas da nam javite na koji napon želite da to napravimo.
(Vaš power bank već je 1S baterija, što znači da je trenutna postavka MPPT punjača OK. Ne zaboravite, kao što sam Vam napomenuo u telefonskom razgovoru, da se morate spojiti direktno na bateriju)
Customer:
I don’t fully understand what the S configuration means for batteries. I need maximum efficiency from the current and voltage of my 12V solar panel. Battery charging speed is very important to me. I’m not knowledgeable in this area, so I’d appreciate your help. I also didn’t understand clearly what you meant by connecting directly to the battery - did you mean the solar panel connects to the MPPT with a cable to the designated port, and then the MPPT connects to the battery?

Nije mi baš jasno sto Vam znači ta konfiguracija S za baterije. Uglavnom treba mi makimalna iskoristivost struje i napona solarnog panela koji su napona 12 V. Jako mi je bitna brzina punjenja baterije. Nisam kompetentan u tom području pa Vas srdačno molim da mi pomognete, također Vas nisam dobro razumio spajanje direktno na bateriju, jeste li to mislili da Solarni panel spojim na na MPPT kablom na predviđeno mjesto i onda MPPT s baterijom.
Unaprijed Vam se zahvaljujem,
Marko
Soldered Support:
S means batteries in series - 1S means one battery in series. Your power bank has one battery in series because its nominal voltage is 3.7V.
You must connect DIRECTLY to the battery inside your power bank, not to the power bank’s charging input. This is because our board is a lithium battery charger and must be connected directly to the battery itself.
The correct connection is: solar panel → MPPT charger → lithium battery (not power bank)
No modifications to the board are needed for your battery.
Please be aware that lithium batteries are dangerous if not handled correctly.

S znači baterija u seriji, pa 1S označava jednu bateriju u seriji. Vaš power bank ima jednu bateriju u seriji jer mu je nazivni napon 3.7V.
Ono što sam govorio je da se morate povezati DIREKTNO na bateriju unutar Vašeg power banka, a ne na ulaz power banka za punjenje. Razlog tome je što je naša pločica punjač za litijsku bateriju i mora biti spojena direktno na istu.
solarni panel → naš MPPT punjač → litijska baterija(ne power bank)
Nisu potrebne modifikacije na pločici za Vašu bateriju.
Podsjećam i upozoravam da su litijske baterije opasne ako se s njima ne rukuje ispravno.
