I have 12 5kVA Victron multiplus II inverters all connected to DC busbar with 13 16kWh deye batteries and 15 250V/100A charge controller which is connected to 90kWp solar panels. This offgrid setup will shut down at 90% with a battery low alarm. I have an ekrano gx for monitoring. How do I stop it from shutting down until the battery is at DoD
please try posting some of the daily log graphs from the advanced VRM pages, such as battery soc, battery voltage and current. Also have a look at the logs to see if any faults are logged. This seems to be a very large system you are running…
Deye is not a supported battery so there is no guide for how it should be configured. For any system, let along a large one, you really want a battery that has been properly tested with Victron.
SOC is also unlikely to be accurate if it is being calculated by the inverter(s).
Voltage is dropping off properly and you are charging it to quite a high level by conventional standards.
You should contact Deye or your supplier to confirm what charge and cutoff values need to be configured as you are possibly misconfigured.
The battery should be configured to communicate with the GX, not sure if DEYE supports Victron comms protocols? If not you need a BMV as internal measurements will be hopelessly wrong.
How is the inverter system programmed? (Besides three phase and parallel)
Referring to 3,4 and 5.
Since you are offgrid, i am going to assume you are not using ess those would be the ones to check.
Read this thread about reducing DC ripple with capacitors. Maybe get in Contact with Jereon.
Pls Graph the DC ripple with current.
The ripple alarm seem to be raised in strong discharge.
Thus would match the linked thread.
Good morning,
Indeed @Bjorn, thanks for linking me in.
When I calculate for a std 48V lithium battery, 10A per KWH installed, then Adaga should be possible to pull about 2000A, meaning starting a heavy load is then 3-4xIn, so, only about 24-30KW can be started normally with these batteries not to switch off on over current and/or ripple.
@Adaga, how long and what size are your DC cables and what fuses do you use in between the inverters and the batteries.
With the very best regards, Jeroen.
