Hey man thanks for the reply you see the specs on the unit Lyfelink 3.8(sunsynk all in one) says the following PV Input data Max. PV Input Voltage 500V Max. PV Current 10A Max. PV Isc 12A It does make it difficult to get panels... i can get but its far away and not always sure if ill get it when buying second hand hence me asking here as there is at least somewhat of a brocode.. As you can see from the specs the other option is to buy 200w panels and then connect them together but space is also a constraint on this side..
