Solar + Inverter + Battery Setup Review

I have been experimenting with solar by buying a 10-pack of Hyperion 400-watt bi-facial panels by using two four-panels strings. That has been working great and I am ready to step up my setup to the next level.

I have ordered the following:

• EG4 18kPV Hybrid Inverter
• 2 EG4 PowerPro WallMount AllWeather (14.3kWh each)
• Pallet of 36 Hyperion 400-watt bi-facial panels

I am having an electrician install the inverter and connect it to the grid and my breaker box. I am personally installing and connecting the batteries and solar panels. I will end up with 46 panels.

The inverter has three MPPT controllers:

• MPPT1 of the inverter supports connecting two strings. Internally it treats then as two parallel strings. It can consume up to 25 amps.
• MPPT2 and MPP3 support a single string. These can consume up to 15 amps.
• All MPPT controllers have a input voltage range of 100 to 600 volts.

Considering the attached drawing of how I intend to connect the panels, would you distribute these any differently?

Notes about the drawing:

• MPPT1 will consume my (larger) ground-mount array
• MPPT2 will consume the gazebo roof-top array (yes.. the gazebo is that large.. lol)
• MPPT3 will consume my home roof-top array.
• The lines for the grounds indicate that those components will be electrically bonded using 6 gauge solid coper wire and mechanically grounded to an 8' grounding rod.
• I have some flexibility in shifting a couple panels from the ground mount to the roof top array but those would be in a less than optimal position.

I really appreciate any comments as this is my first time doing a large solar project.
