How many Pylontech US5000 are recommended from a performance perspective

Heya,


I have (is due to be installed) the following:

  • 16 x Hyundai 485W HiE S485VI panels
  • 2 x Victron MPPT 250/100-Tr VE.Can
  • 1 x Victron Quattro 48/10000/140-100/100 230V VE.Bus
  • 1 x Victron Cerbo GX
  • 1 x Victron GX Touch 50
  • 1 x Victron Battery switch ON/OFF 275A
  • 1 x Victron Energy Meter ET112 - 1 phase - max 100A
  • 1 x Victron Lynx Distributor
  • 1 x Victron Lynx Shunt VE.Can
  • 3 x Pylontech US5000 batteries


What do you think about this configuration (panels will be mounted on ground facing south)?

Also what is the number of batteries recommended from a performance perspective given the above setup?

Thank you

Each US5000 module is rated for a recommended current of 50A.
A 10kVA Quattro could draw ~200A at it full rating, probably more for short periods of time.
So I would say 5x US5000 modules would cover the requirements safely.

Performance is relative....

With the 16 panells you could generate 30-40+ Kw/h... or 6-7 Kw/p less in winter

But what is your load / consumption overnight and during the day?

What are your peak loads what is expected to remain in solar production after consumption during the day to fill batteries.....

If usage is only 5Kw/h at night 3-4 5000 is ample ...

Like @WKirby wrote to use the multi full tilt 5 5000 prob min. and serious cables.

But then if one throttles the max output to extend life of equipment etc. ....

SOC between 100 -10% or rather 100 - 40 % .....

Give us some more ideas on what you want / need to achive...
