So, the contractor is starting the install soon. I have a EG4 18kPv which has 4 Pv Inputs, but only 3 MPPT's. PV input 1 & 2 (as MPPT 1) comes parallel on the inverter with a 25amp max on MPPT 1. See image.
The contractor says he wants to put the panels in a 8 by 8 Parallel config for MPPT 1. With 7 Panels in series on MPPT 2 and 7 panels in series on MPPT 3. For a total of 30 panels. 370 watts each, bifacial gain of 444w.
I want to follow along with the install to ensure a smooth process but instead of giving my an explanation on why this way is better his answer is always "just trust me, just trust me". My question is, putting the panels in a 8 by 8 parrel config, will this be too much amperage on MPPT1?
I've attached MPPT diagram as well as panel info.
