About a year ago, I had a photovoltaic installation which included a Victron inverter, MPPT, Lynx distributor, Cerbo GX together with two LEOCH Lfeli 48100 batteries(9.6kWh).
I have been monitoring the performance by downloading the data from Victron onto a spreadsheet and there seems to be a considerable imbalance between the charging and discharging of batteries. For example, last April the batteries in - 202kWh and batteries out - 133kWh so where has the difference of 69kWh gone?? Annually this aggregate amounts to some 700-kilowatt hours.
Subsequent to the installation of the batteries I have discovered they are not included on Victron's list as being compatible.
The batteries are set to a minimum SOC of 20%, the DVCC is set to ‘on’, as is the limit charge current and the maximum charge current is 100 A. The ESS is set to "optimise without battery life".
I have, as yet, to receive an explanation from the installers and any help or advice that you could give me would be very gratefully received – as you will have gathered, I am a layperson with limited knowledge.
