Mppt problem in ESS

dear experts! in my system the problem is with two mppts (150/100 and 150/70) System composition: easy solar 5000/48 mppt 150/70 mppt 150/100 (inside easy solar) solar panels 2.5 kw west and 2.5 kw east. battery Dyness power depot H5 100ah The system is configured as ESS. The problem is that a very small generation. a lot of sun. Now I found that both mppts see different voltages on the battery (I'm attaching a photo).


for two months, the maximum that I have seen is 1.5 kW from both controllers at the peak, although the SOC battery is 30% and there is a load. What can limit generation? Thanks

U should activate DVCC, but also need to have a Smart shunt or BMS for best measuring and triggering the dvcc well
