At the moment I own 2 packs of 10kwh in lithium batteries connected in parallel to 48v.
I was thinking of putting a multiplus II, or a multiplus 5000. We both would be connected in parallel to grid.
Given that the multiplus II is recent would be preferable, for what I intend?
Meanwhile, the idea of putting 2 multiplus in parallel (each destined for each pack of 10kwh) came up to better take advantage of the 20kwh. Would it be better idea to opt for a multiplus 5000?
I think I gain in power to inject in my house with the multiplus II (2400wx2), against 4000w of the multiplus 5000). On the other hand, if one fails, I always have the other.
I intend to use solar energy essentially from the Mppt side for efficiency. For my configuration of 2x20kwh (32cells), with 2 multiplus II would it have to have 2 Mppt?
Thank you for a quick response from someone who can help me decide.
