Hi guys! So I have an AC coupled Offgrid system running my house, 13kw on the roof ,sunny island 8, 2x sunny boy 5's and power plus batteries, I want to add another 5kw but I've been told I can't add another sunny boy inverter, he suggested I change to DC coupled system and add a victron mppt, can anyone give some advice , I dont know which way to go!
Many thanks Gary
