Hello, my system is single phase, consists of a 3kw huawei solar system on the ac in side, one multi2 10k, two 17kwh 16s(52v) lifepo4 batteries with jk bms,150A charge limit for each battery, for a total of 300A of allowed charge current, 500a smart shunt, cerbo gx, and a fronius primo 6.0 with 9.0kwp solar system on the ac out of the multi. Every single devices firmware is up to date. No charge limits set. Ac coupled pv feed in excess is enabled, feed in is limited to 3kw. My multi is set to 140A(max) in VE configure. If i set ESS to optimized withput battery life (or with battery life) the multi will only charge my batteries with around 80A. If i set it to keep batteries charged, multi charges with 120-125A.
Why wont it charge my batteries with the maximum settable 140A? Why does the optimized mode only charge with 80A? Yesterday my batteries were discharged, to around 50%. It still woundt charge with more than 80A ±.
You can see it in this chart, started chargeing in the morning, fron 70% soc. Never reached over 80A.
