Hi,
i have 3 Multi RS Solar, AC Inverters and a GX Device. All on the latest FW.
This morning the battery had 70% SOC and when the sun came up only a part of the energy was fed into the battery (only 2,5kw on a 1000Ah Bat). Most was feed into the grid, what was totally fine because the bat will be full today, since we will have a sunny day.
Is this a new feature of victron or any error? My expectation was dump charging the bat with will power and after 11am feeding in the grid. I just want to understand what the system is doing.
DVCC is enabled but i do not think that the bat thottle this hard at 70% soc.
Are the batteries LifePo4?
If they are
How cold were the batteries?
My non Victron system throttles back charging when the batteries are below 2degC as they were this morning. This morning batteries at 70% 2.8kW from panels, 1.6kW to the batteries and 1.2kW to the grid.
Yes, if DESS is certain to reach 100% soc no matter what, it will not necessarily charge the batteries with full solar available.
Lot of other considerations taking place, Feedinprices, configured limits etc.
Sometimes it may also just be a overestimated ac load (or underestimated solar), that causes dess to select a (s)lower chargerate for the battery. If the expected load then doesn’t happen, it may feedin in it’s current version.
How can i set the ~50A the bat is charged?
The current CCL Limit from Battery BMS is 1000A.
Even a reboot of the gx device does not change this symptom. RESULT: I found it. In DVCC the charge limit was set to 50A manually. Raising this limit fixed my problem.
