I have a Victron installation which includes the Multiplus inverter 48/5000/70 with ancillary equipment together with 5 Pylontech US5000 batteries (which have in aggregate capacity of 22.8 kilowatt hours but the SOC is set to a minimum of 20% therefore 18.25 kilowatt hours)
I would be very grateful for some guidance on how to configure the dynamic ESS. I ideally need to know what level I should set the maximum import power and the maximum out power . I’d also be grateful in respect of the battery settings what I should set the maximum charge power and the maximum discharge power to. I’m a layperson I think I can understand the remaining inputs guidance on the above would be gratefully received together with any other help
Well, that depends on what you want. How is your battery charged? How should it be charged? Exclusively with PV power (MPPT and/or PV inverter?) and/or with grid power? And then the question is whether your grid can provide sufficient charging power. If not, you’ll need to reduce the MP-II’s charging current accordingly. How much PV power is connected to your system? LFP batteries can generally handle a maximum charging current of 0.5C, which in your case corresponds to approximately 11 kW. If you have more solar power, you’ll need to reduce this.
Do you want to feed surplus PV power into the grid? Do you perhaps have more PV power than the MPII-5000 can feed in? Then you need to reduce the feed-in power. However, you can also feed very high PV power into the grid if you do it with a time delay, for example, with 1000 W continuously even at night.
If you don’t have dynamic grid pricing then don’t bother with dess used scheduled charge in ess.
You can set different levels of state of vhaege and whether you want pv only for loads or both loads and charge for different times of the day and even how and when the battery isnused.
