Hy community,
i have 4 x JASolar JAM54S30-400/MR (11BB) 400 Wp and i want to purchase a all-in-one solution like the EasySolar 24/1600/40. Does the EasySolar work with those 1,6kw peak the panels can deliver? And would it be possible to upgrade it to 2kw?
big thx in advance for your help!

I see that you already know that the Victron 100-50 mppt has a PV output limit of 1400w or so.
It is essential that you keep below the 2 main mppt design limits. PV array Voc @ lowest expected climate temperatures. And PV array Isc limits.
An array of 4 JA solar 400w panels be a good match for a 100-50 mppt, when wired up as 2 series/2 parallel. Unfortunately 5 panels can only be wired up as 5 series (danger over voltage) , or 5 parallel (danger over Isc current)
Personally I would avoid those JA panels, simply as they are unique. Should you ever need to replace a damaged panel, it would be really hard to find a near equivelant.
big thx for your answer! just for understanding. in the specs of the EasySolar 24/1600/40 is mentioned that the max pw power is 1400w. Does this mean that 1400w overall or per port?
While you're writing about 2series/parallel i think its per port, right? :-)
The 100-50 mppt has a maximum power throughput of about 1400w. PV array to 28 volt battery.

ah ok understood, thx. with 2 series/2parallel i will get 48v output (as the jasolar are 24v each) correct and this will not fit for the EasySolar 24/1600/40, correct?
It would work, but you will not achieve full panel output. For that you need a 75Amp controller.
You could also add a second MPPT wired direct to the batteries. This would allow all the panels to operate at full power, also giving you some headroom for future expansion. Bearing in mind what @klim8skeptic said about these panels.
