Customer:
I have two questions about the Inkplate 10 display.
Does the built-in charger support LFP batteries?
Can a solar panel be connected in combination with a battery to charge the battery as needed? If so, how?

imam 2 pitanja u vezi Inkplate 10 displaya.
Podržava li ugrađeni punjač LFP bateriju?
Može li se spojiti solarni panel u kombinaciji s baterijom koji bi punio bateriju koliko je potrebno? Ako da, kako?
Hvala,
Lp!

Inkplate does not support LFP batteries because the operating voltage range is completely different from Li-Ion batteries, and the maximum voltage of a charged LFP battery is quite different, which would cause overcharging and destruction of the battery.
A solar charger can be connected in several ways. The easiest is to connect it to USB and use it that way, but the problem is that you need a solar panel with sufficient power to run Inkplate (more than 500mA current and 5V voltage). Another option is to disconnect the charger power pin from the board and connect the solar panel to it, then connect the battery to Inkplate. Inkplate would run on the battery while the solar panel would only top up the battery, and there would be no problem with solar panel power in this case.
If you want to use the full potential of the solar panel, it is best to get a separate solar panel controller (MPPT or PWM), connect the battery and solar panel to it, and connect the output to Inkplate (ensure that the output is 5V if connecting to USB).

Inkplate ne podržava navedenu bateriju zato što je opseg radnog napona potpuno drugačiji od Li-Ion baterija i maksimalni napon napunjene baterije je dosta različit tako da bi došlo do prepunjavanja iste i uništenja baterije.
Solarni punjač se može spojiti na više načina. Najlakše je spojiti ga na USB te tako koristiti, ali tu je problem što morate imati solarni panel dovoljne snage da može pokrenuti Inkplate (više od 500mA struje i 5V napona). Druga opcija je da odvojite pin za napajanje punjača od pločice i na njega spojite solarni panel te uključite bateriju u Inkplate. Inkplate bi radio na bateriji dok bi solarni panel samo dopunjavao bateriju te tu ne bi bilo problema sa snagom solarnog panela.
Ako bi htjeli iskoristiti puni potencijal solarnog panela najbolje je uzeti zaseban kontroler za solarne panele (MPPT ili PWM) u na njega spojiti bateriju i solarni panel, a izlaz spojiti na Inkplate (osigurati da je izlaz 5V ako se spaja na USB).
Nadam se da sam pomogao ako je potrebno detaljnije objasniti neki od načina spajanja slobodno nas povratno kontaktirajte.
