Charging Batteries on Grid at Night Rate

[Muhammad Umar]

So installing large batteries trend is increasing worldwide as people charge them at night rate and utilize their energy during day time (6AM-9AM). So do PVSOL Premium offers any option to charge the batteries during night hours (night tariff rate is quite low as compare to day tariff).

Thanks

Hi Muhammad,

unfortunately this operation mode is not yet available in PV*SOL premium. We have this on our list though, but right now we can't name a date when it will be published.

Kind regards,

Martin

No more news on this function being offered to PVsol users soon? Now almost all our customers are installing large battery packs, well in excess of 10kWh just to benefit from night cheap charging.

Hello.

No news about this feature yet? I've noticed that there are topics in the forum more than a year old without a response.

Is there any official roadmap for this and other new features in PVSol?

Best regards.

Unfortunately I do not have any further information about when we will be able to implement this into PV*SOL.

We do not have an official roadmap but I will bring this into our team and see if we could publish something.

Kind regards

Is there any kind of workaround to simulate this in the meantime? So we can get realistic figures for an installation with grid charging batteries.

We've been asked about "intelligent charging" solutions, as Riello RS Hybrid, that allow charging and consuming from PV, batteries and grid following multi factor  policies (hourly programming, according to tariff, etc.). So the demand and PV+battery curves fit better. Such equipment is not in PVSol database, but even if I create it from scratch it lacks the charge from grid options.

Hello omicron_solar,

it is possible to charge the battery from grid at night by using the time controlled charging but unfortunately it isn't possible to specify a separate night tariff for this.

If you assume that the battery is charged from the grid exclusively at night, you could multiply the charge from the grid in kWh by the night tariff.

You can see the total annual energy flow from the grid to the battery in the energy flow diagram.

Kind regards
