PV Options Advice

[vma]

Hi guys, I am looking for some advice in choosing one of these 2 options

Option 1:

• 6kw Polar S Hybrid Inverter for 2 strings
• 4 Tigo Optimisers on the garage roof for shading issues
• An additional 3.6kw Solax String Inverter connected directly to the grid for the 3rd string
• Total system capacity: 9.6kWh (6kWh + 3.6kWh)

Option 2:

• Single 6kw Polar S Hybrid Inverter
• Both garage roofs are on 1 string
• 12 Tigo Optimisers are required due to different roof orientations
• Total system capacity: 6kWh

Common elements:

• 435w Jinko N Type All Black Panels
• 5 x 5.2kwh Batteries = 26kwh Total Capacity
• Same price for both options

I've had issues with tigo optimisers.
Not sure if they have fixed them or not, but 3 of my 12 failed and I struggled to get my installer to believe me!
