Hello,
imho it's a smart move of Victron to make all-in-one devices, as sometimes the puzzlework can be overwhelming for beginners (still).
short-story: it might have been asked before, but some folks can't afford a battery, is it possible to run a EasySolar 2 5000RealkW without a battery?
it is NOT recommended but possible with the MPPSolar (Voltronic) and DEYE (https://www.youtube.com/watch?v=g4xZGJ0gMaw) inverters (but they in contrast can mostly NOT feed to grid!) as this would mean: 1. no energy at night 2. every morning: switch-on, every evening switch-off: every year: on-off-on-off-on-off-on-off-on-off... which might reduce electronics lifetime.
long story: prices have gone done massively check out this very honest vendor of EVE LiFePo4 batteries https://www.kleinanzeigen.de/s-bestandsliste.html?userId=125907624 not sure if Victron likes these kind of links in forum posts? alternative would be https://lifepo.de but they don't care if a 280Ah actually only has 270Ah (or less))
+ JKBMS (can NOT handle 15S only 16S which is no good, what if a cell goes bad and replacement is hard to get?)
thanks in advance and sorry for the links to "non Victron" products
maybe folks can afford a DIY battery LiFePo4 + JKBMS like buy 1x cell per month :)
