Off-grid system with battery

[José Cabrera Escobar]

I have an off-grid system with a battery. This battery doesn't require its own inverter; it uses the main inverter. How can I design this in the software? The problem is that the software requires a battery with its own inverter, which isn't my case. I want to model a system with a Goodwe GW5K-ES-LD-G10 inverter and a Goodwe LX A5.0/30 battery.

Dear Valentin Software

 

I would like to carry out a simulation with a Goodwe GW5K-ES-LD-G10 inverter, but when selecting the battery, it asks me to choose a battery inverter and a battery, as shown in the figure..

 

 

 

I am using the Goodwe LX A5.0-30 Series battery, which does not require a battery inverter and connects directly to the main inverter, the Goodwe GW5K-ES-LD-G10. How should the configuration be carried out in this case?

Regards

Dear José Cabrera,

Thank you for your inquiry.

We recommend that you plan your stand-alone system as if it were a grid-connected system, as described in our FAQ: How do I plan a stand-alone system?

Dear Valentin Software

I have used the proposed system.

But when selecting the battery, it still asks me to choose a battery inverter and the battery. In my case, my system does not require a separate battery inverter; it operates with the main inverter.

Best regards,

Dear José Cabrera,

Thank you for your inquiry.

In PV*SOL, a battery system always consists of a battery inverter and a battery. If you are using a hybrid inverter that you already selected when configuring the modules, then select the same device a second time when selecting the battery system.

We contacted the manufacturer and asked them to add the missing battery system. Unfortunately, the manufacturer has not yet replied. We are also unable to set up the battery system ourselves because we lack information about the inverter that is not included in the data sheet. We will contact the manufacturer again.
