Solar Design - Need assistance

I am busy designing a off grid solar system for myself... I am not a qualified electrician and did all my research on the internet and reading lots on the Victron Web sites.


I want a 10kVa system (+/-).

So:-

20 x 330 Watt Panels (connected in series in 5 strings of 4 panels)

into 1 x connector box (with a fuse on the positive (LS BKN C63A (230/400V~))

Connected to:

1 x Victron Energy MPPT 250/100-Tr

1 x Pylon US2000B Plus 9.6kWh Li-Ion Battery

1 x Victron Energy Quattro 48/10 000/1401


do i need anything more?

Yes, you need an installer, and / or Victron distributor to walk through the system, and to (help) install it.

-your battery needs to be at least 2x the size, and probably 3x/4x in practice due to battery limits based on temperature, SOC, etc.

-you need a Venus device to let all components communicate with each other and bms
