I have an install using a Multi RS that is off grid, solar supported b
y a generator on AC in.
The issue is that it will pass through from the generator to run load but won’t charge the batteries (Dyness).
The current limit is set to 10A, the voltage and frequency of the generator are fine, and the multi connects to it easily, it’s just the charging issue. The multi is set to ON.
Cany suggestions?
Did you try to set AC input type to “Generator” in VictronConnect?
Yes it is set to generator
Most of the problems I saw with generator is non-sinusoidal generator waveform, so the generator produces a distorted sine wave.
Does it charge on charger only position?
No it still passes through whatever load is on AC out 1. The frequency and voltage are good and stable.
Is the load close to the 10Amps input or is there no load on the inverter?
Small load on the inverter but it shouldn’t matter, the unit should charge the battery according to the input current that is set.
I suspect that this is a faulty unit rather than a software problem. Its not easy to get any assistance relating to the multi rs..
Do you use a Cerbo-like device? Connected to the battery?
If yes, try to disable DVCC, if enabled and see if it’s charging.
Or try without it (Cerbo) altogether…
A further thought, if the ESS (in the multi rs)was set to keep battery charged or had a percentage for reserve set, that may affect whether it is charging from a grid source or not.
