Hi Everyone!

I just need help in figuring out how long in "real time" will it take my batteries to be fully charge. Here's the deal:

4pcs. 100w PV Panels @ 12v each and 5.71a.

>I wired two of them together in series to make them generate 24v

>In the philippines, we get an average of 5 full sun hours per day all throughout the year, so I'd be generating around 2000wh or 2kwh per day in an MPPT controller.

I have 2pcs. 12v AGM batteries @100Ah each.

>I also connected them in series to make them 24v @ 100Ah.

>I know that with my batteries, I have 2400wh of stored energy (but I will only use 600wh out of it).

Question: How long will it take my Panels to top of my batteries if ever @ the following states?

70% SOC or 1680wh available=?

75% SOC or 1800wh available=?

80% SOC or 1920wh available=?

Please share the formula as well if possible so I can compute it on my own in the future.

Thanks!
