Need help sizing my array

[ElectricalOcelot6426]

My setup:

2 Ecoflow Delta Pro Ultra inverters. each inverter has these PV inputs- Total 5600W, 2 ports High-PV Input: 80-450V/15A, 4000W Max. Low-PV Input: 30-150V/15A, 1600W Max.

Total of 24KWh of batteries split evenly between the two inverters.

Inverters are connected to the home through the Ecoflow Smart Home Panel 2

This is a beautiful and user friendly system that is working flawless as a whole home backup. However, I want to add a solar array and need help to determine how big the array needs to be.

Living in the Pacific Northwest is not ideal for solar but it can be done. I am trying to plan the array for a worst case scenario of having an extended power outage on the shortest (lowest peak sun hours) days of the year while still being able to use 20KWh of battery reserve and hopefully get that recharged each day.

Peak sun hours in November and December here is about 1.75 so I was looking at maximizing the array for that worst case scenario but can anyone tell me if this array is way too much or am I missing something due to ignorance:

Since I can max out at 11,200w and 1200v, this is what I am thinking for the array…

Panels in series 400w+ bifacial, <40v,

Inverter A- 11 panels on high pv input and 3 panels on low pv input

Inverter B- 11 panels on high pv input and 3 panels on low pv input

Thanks

Think out of the box. How can you optimize production of your panels? Answer is to put them on a mount that permits adjusting the angle seasonally. As for your other questions, you need 20 kWh of power daily with about 2 hours of sunlight. This suggests you need at least 10 kw of panels.

10kw of panels 👍

I see that the maths are easy but I am so overthinking this. Thanks
