Hello,
I have a small project wich consist of creating a solar MPPT charger and I have some questions.
1 - What does the MPPT do ? I know it's an algorithm implemented in microcontroler in order to control a DC-DC (Buck or Boost) converter but I don't really now how it works, does it change output voltage (battery) or input voltage (Solar panel) in this case ?
2 - Is the output voltage of the DC-DC converted imposed by the battery or by the MPPT (With the variation of duty cycle) ?
3 - Is C/10 the maximum current to charge a lead acid battery ? Can we charge with higher current ?
4 - How to measure battery temperature ? Using LM35 sensor ?
5 - What does kill the battery, the higher current or the higher temperature ?
6 - I have a 10 Watts (MPP @ 17v 0.6A) solar panel and I choosed a 12V 7Ah lead acid battery, is it a good choice ?
Sorry for my english and thank you for you help.
