Multi-battery design

[lozano2]

Hi

I need to load banks of batteries OPZS (850 Ah c100) with one diesel generator of 60 kW.

The time of load foreseen is 6 hours a day.

Can someone recommend to me the most suitable system of load?

Thanks

Your question does not make sense. You don't "load" batteries with a generator.

A generator and chargers of batteries.

Thank you

Still unclear to me.

Perhaps you need to spend a few more characters and explain in detail your problem.

The aim is to take advantage of a power not used in the generator to load batteries.

The problem is that it is a lot of power the generated one. We would need banks of batteries and a suitable system of load.

This it is the problem.

I do not know if the problem is understood well

Thanks

Still unclear. Are you referring to charging the batteries, i.e., storing the excess power in the batteries?

And, being able to withdraw the stored power at a later time?

Yes, I am trying it.

These are 2V batteries?
What voltage is your generator?

Offhand, you're looking at something like 100 batteries for a 30kW*6hr excess capacity, assuming an 90% efficient charger.

- The Voltage of generator is 110 V.

- 2V batteries OPZTS.

I'm not sure why you selected your batteries prior to designing the system.

While not specifically suitable, a UPS has the architecture that you desire:

Just bear in mind that a UPS is typically specified for 10 minutes of operation at full capacity, so you'd still need the equivalent of 36 30kW UPS systems to store a my assumed 50% excess, which you have not specified. I would suggest that you contact someone and have them configure a customized installation.

The depth of discharge is low in the SAI. I think we need many items.

Is not it better to use lead acid batteries with high discharge depth?

Thanks
