Hi, I have bought a 5kw deye hybrid inverter and I see that the Pv input current is 13A per string. I have 10 x 600w Canadian solar panels on my roof with a 17,2 A output. Will the deye 5kw handle the 17A per string or will it block it at 13A ?

Thanks Marius

Usually it will just clip the amps above 13, but there are limits to everything. Check the sticker on the side of the machine for the maximum PV input current allowed on the inverter. My 5k Sunsynk states "Max PV Isc: 16.5a DC + 16.5a DC" You may have to send the panels back in favour of ones with a max closer to 13A. 

Then there's more bad news: You are wasting potential PV power, because even if it clips, you are losing 25% before it even reaches the inverter. So another good reason to send them back.

And when you do, please take the opportunity to kick the butt of the salesperson who sold it to you, they really ought to know and advise better. Something like this will never happen at The Powerforumstore.  

Edit: and another thing: if a 600W panel pushes 17.2 A then it means that voltage would be around 34.88V per panel. If you put 5 in series per MPPT, you will get a very low voltage of around 174.4V max. This means that the MPPT (which needs a minimum of 125V ) will startup a lot later in the morning and stop a lot earlier in the afternoon. So they are really very poorly matched panels for your inverter 😧

I would not say it is such a train smash. On average a 17A panel will yield 14A in Gauteng. If it clips it will only be a loss of 1A. Yes on some ideal days the panels might reach 17A and then clip it to 13A. 800W NMOT values below. 

Will my 5Kw Dye inverter handle a 0,75kw 4pole motor start up?
