I installed Solis inverter (6kw s5-eh1p6k-l) with 2* 5.0c Dyness batteries and I have two main issue and I was wondering if anyone experienced the same.
The first problem is, the battery charging limits sometimes drops to 20amps, limiting the charging power to around 1.12kw total to charge both batteries, first I thought there is no enough solar input but there is, when I turn something in my house on, the power from solar increase to 2kwh, and once I turn it off, it drops to 1.12kwh again, and when I change the charging limit, it reset once I click save, I found online that the battery BMS is setting these values so that is why it sets to what the BMS comminicate with the inverter.
sometimes it takes hours to get the battery to like 50% and than it start charging using full solar power but usually it is too late and the sun is already about to sunset. so most of the days I lose more than 3 hours to get the battery to 50%.
I tried today to turn the inverter off completely and turn it on again and it worked and the charging limits becomes 100amps, I tried many things and same problem.
the second problem that I know it is a big problem, during the night, the load in the house is 30w and the battery is draining very fast around 210w all the night! for example yesterday I lost around 14% of the battery in around 6 hours!
yesterday, it drop from 24% to 9% in 5 minutes, just by itself, is it possible an issue with the batteries? I already contacted Dyness but there is no response, and I contacted solis and they updated the inverter to the last framework but this changes nothing.

tried to find any useful information online but nothing.
I chechek everything and replaced the RJ45 cables too, I switched the batteries from master to slave and same problem.
