Pylontech is bull...t. Make self. Buy from alibaba 304ah cells 16pcs, aprox 2000€ 16kwh + 123Smart BMS. 60kwh is good for 3x 48/5000 multiplus 2. You have 16kwh 48v battery 2,5k€. Why this Touch GX ? Lot of money only. You see all this from lan computer, tablet, cellular. I have these and think buy + 3 Multis 48/5000. More power, +12kw.

hi, what do you mean with 12kw?

my advise is to consult your local victron dealer/installer if you aren't technical enough to setup a system like this

Ok, 4000w is the max it can deliver continues at 25 degrees, the warmer it gets the lower it can deliver… (temp derating) so all depends on what you want to run
