Hi Victron Comunnity!
I am installing the following system:
1 Multiplus II 3000/48 35
1 Pylontech US3000
1 MPPT Bluesolar 150/70
1 Venus GX
3000 watt in solar panels
The question I do have right now is: Would the system work? Given that the peak current limit of pylontech batteries are 100Amp per 15 seconds, and the Inverter peak watts surge ratting is 6000W (125 Amps for a 48Vdc configuration)?
Thanks a lot!
This isn't the best system design but it would work, as long as you don't run really high loads on your inverter. This isn't a good design because under certain load conditions you will trip the battery off.
Also pylontech batteries don't do well close to their limits. I would not run more than 2000W continuous with just one module.
My only question is, if for the fist stage, the battery will be able to run the Inverter for the first time, because of the surge rating (charging the capacitors).
The pylontech has a mosfet based BMS so it does a soft start when you turn it and you don't get high inrush currents like you would on a contactor or circuit breaker. I tend to pre-charge from PV if that is available.
