MPPT 250/60 and 150/60 parallel to BYD B-Box Pro 13.8

Hello dear community,

Quick question, hopefully not too complicated. I have planned a system with 17 solar modules of 300 watts. Due to their configuration I have chosen an mppt 250/60 (driven by 4 series x 2 parallel = 2400 Wp) and a 150/60 (3 series x 3 parallel = 2700 Wp). Both were checked with the Victron configuration Excel app, and are well in spec at my temp range.

I will be charging a BYD B-Box Pro 13.8 kWh with them. The 2 different MPPT will be connected to a Victron Colour Control GX, along with the B-Box's BMS. Is this configuration possible, or do I need to get identical MPPT charge controllers?

In addition I will have a Multiplus Inverter/Charger 48/1200 VA running from the battery to run a single 700 Watt consumer 24/7 (grid/genset back up will be available).

Please let me know if my thinking is skewed here and I am welcome for any suggestions!


Many thanks and best regards


Fabian

That is fine to have 2 differently sized MPPTs.
