I have the same on my system, 18x 355w facings North East ( Southern Hemisphere and orientation of the way the house was built) adding 6x370w to the west facing to extend afternoon PV and will give us more power generation in the afternoon to have a full battery bank that has around 24h if capacity on our night time usage, haven’t touched the grid power in the last two weeks while running the household and my Wife’s Salon , Ac , borehole, irrigation, swimming pool, started putting the system together 5 years ago and saving every day now ! So rewarding 👍
