minimum battery requirement

Will multiplus 2 work without the minimum battery requirement (for each 1.5kw pv 4.8kwh battery)? For example if i have victron's multiplus 2 and ac coupled pv 15kwp using fronius, (without sending energy back to grid) during the day most of the pv power will be used by the loads (AC, servers etc.), will 15kwh 300ah lifepo4 batteries (150a bms) be enough?

@terkazarian

I think this (1.5kWp - 4.8kWh) is a suggestion and not a hard rule.

You will have to limit the max charge current.

I have 18kVA 3 phase system with 16kWp in panels and once had 10kWh LFP battery without problems. Now have 20kWh battery tho.
