Victron with Enphase System Build

Hello All, I currently have a 4kw solar system with enphase m250 micros. We suffer constant power outages in the area and I would like to add on a storage solution. I was hoping I could get a little input on system requirements;

Currently I am planning to order the following:

1x Quattro 48v 10000va

1x Smartsolar Charge Controller

1x GX Touch

1x Cerbo GX

5x Pylontech US3000c

1x VE.Can to CAN-bus BMS type A Cable

Anything I am missing? Would you change anything in this list?

I appreciate any input!

Will you add a generator to the Quattro or will a single ACIN 10kVA 48V Multiplus II suffice?

Do you plan on adding more DC coupled solar to want a Smartsolar MPPT?

Do the Enphase currently disconnect during power outages and are you looking to connect it to the ACOUT essentials loads output?

I dont 100% know what I want but I would rather have the flexibility for future expansion.

I wont be currently adding a generator, but I would like to have the flexibility to add one in the future.

In regards to adding more DC coupled solar, again looking at flexibility and perhaps adding additional panels in the future if needed.

Yes, the enphase shut down currently when the grid goes down. I understand that I can connect the enphase string to the AC Out 1 and the Cuattro can control the frequency when there is no grid and keep them online.

Thanks for the reply.

@ECT

Ve direct cable to connect the mppt to the gx.

There are quite a few posts on this forum about using Enphase with Victron. It may also be worth reading them before proceeding with anything.

There are alot of design considerations as @ejrossouw has mentioned.

Yes, I have read most of them. I think I am ready to pull the trigger and make the order. I will add the VE Direct Cable.

-Thanks!

Nice. If you can spring for one more battery as well. It will be most correct for the 10kva.

10 000 ÷ 48v is 208A from bank.

208 ÷ 37A (nominal current for 3000c) is 5.6 batteries, but since you cannot buy 0.6 of a battery.....

If you also want to see the Enphase system in Venus OS you can use this driver: https://github.com/mr-manuel/venus-os_dbus-enphase-envoy

It displays the PV input and you can enable the output to MQTT to track the production of every single panel.
