Hi everyone:
I am a newbie and I just posted the below discussion in the newbie section by mistake.
I want to build a 5k solar system to be used during sunny day times only. The maximum load power consumption is 2900w. Taking around 1.5 factor of the DC to AC power conversion, the load consumption is always lower than what the panels produce. Since the system operation is during sunny time, I want to minimize the battery bank just enough for the system to operate without shortening battery life or damaging it.
Assuming the battery is charged , my confusion is that I am not sure how the inverter is fed from ,the battery or from the solar panel through the MPPT controller. Does the fully charged battery in the system acts as a charged capacitor and in this case the current to the inverter comes solely from the panels? Does it fed from the battery and in such a case the battery is always in charging and discharging state.
In case the battery is completely discharged for some reason like unexpected shadow on the panels , is there a way to decrease the charging current in order to protect the battery from fast charge.
The question might seems naïve to some, but I greatly appreciate your feedback and it helps me understand more how the system works.
