For each of your 800W PV arrays (2x400W PV modules), when used with a 48V (nominal) battery, you need a charger which can output about 15A. But the smallest 150V MPPT charger from Victron is 150/35 (you could connect a 2000W PV array to it). The upside is that it will run cooler with only 800W.
But over the long term, discharging below 50% is going to wear it down. That is why solar power users suggest to stick with the 50% mark. When recharging, stop at 85% because charging up to 100% is not good either. If you want to use full battery capacity, get a high end AGM battery bank which can go up to 70%. Or better yet a lithium battery bank.
