I bought a 5KW deye to replace my Growatt SPF5000ES with 9 panels 540w in string. I have read the datasheets and manual before buying and there is no mention of the limit of 3250W per MPPT on these documents. Even the seller said 9 x 540W panels in single string would work fine. I didn't want to rewire the array to separate it to 2 strings
I just found out about this limit which is only mentioned on a sticker placed on the side of the inverter
Now I will receive the inverter in 2-3 days from China so there is no going back and I have to use it. So I decided to rewire the 9 panels to separate it to 2 strings.
I'm going to break it to 5 panels + 4 panels and I'm worried that the 4 panel string might not be enough for optimum output.
Deye MPPT range is 150-425w
My panels are rated at 39V Vmp at NOCT. JA Solar 540w. 'm in Sri lanka so the temp is 26-30c around the year.
Do you guys think 4 panels in MPPT would work fine all day optimally? 39v x 4 = 156W which is just 6v above MPPT range
Honestly If I knew this before I wouldn't have bought the Deye because now I have to spend money on rewiring, new SPD's, breakers and PV disconnect switches
Thanks in advance
