I want to add more charging capacity to my victron ESS system moslty for the winter/dull days.
(multiplus 48/5000/70, 4 x pylontech us2000 and 4kw solar Edge)
Looking at getting a 100/20-48v.
The choice of panels I have are
4x 285w 2series 2 parrel (voc39.3V isc 9.5A per panel)
2 x 325w in series. (voc40.7V isc 10.37A per panel)
2 x 375w in series. (voc47.75V isc 10A per panel)
They will be on a flat garage roof s/w facing so will not have max sunlight.
All check out on the victron calculator but with 4x285w showing Amber charge current of 20A
Im thinking 4 x 285w for most efficient in bad conditions, but some expert advice would be much aprociated.
