currently don't have access to AC PV sourcing / linking assistant I believe it is because my unit is behind on firmware,
previously was DC linking a sepparate 3rd party MPPT controler to the batteries, however have a SMA Sunny boy inverter ready to wire in but can't until i get this firmware
where can i download the updated firmware that supports PV shift power control from?
also all of the labels and stickers I've put details below.
