Hi All,
I have 3S2P West and South facing arrays. This is working well during the day and keeps the battery topped up before the sun goes down.
MPPT - 150V 15Amp
Solar Panel - 45VOC / 11amp per, so each South and West array has max 135VOC and together produce about 19amps total (because each array never peaks the same time)
Mounting angle - 45degree fixed (maximize production in winter)
Question - Can East facing array added without fuse? Since current is not going to exceed 25amp due to panels orientation.
What are trade off of adding a East facing array to the same MPPT?
