Hi guys! My first post so go easy!
So I'm in Australia, we are fully Offgrid running ac coupled , a sunny island 8, 2x sunny boy 5's and power plus lithium batteries, with 13.6kw panels,
So my problem is I need to increase the system, I have another 10kw of panels,( planning on making 2 x5kw strings) and thought I could add another 2 sunny boy 5's , but a local installer told me it's not possible, and that I should really add a victron 450/100 mppt, if thats our only real option so be it, but I already purchased the 2 extra sunny boys, got a good deal so decided to get them,
So really my question is if it is possible?
Many thanks in advance for any suggestions
