FAQs

1. What is a solar DCDB?

A solar DCDB, or DC distribution box, combines and protects the DC output from solar strings before that power reaches the inverter.

2. What is the difference between ACDB and DCDB?

A DCDB is installed on the DC side between the solar array and inverter, while an ACDB is installed on the AC side after the inverter to distribute and protect inverter output.

3. Why is a solar DCDB important?

It helps isolate faults, protects strings from overcurrent and surge conditions, and makes the solar plant safer and easier to service.

4. What protections are normally included in a DCDB?

A typical DCDB can include fuse links, DC MCBs or MCCBs, surge protection devices, isolators, terminals, and busbar arrangements depending on plant size and inverter requirement.

5. How do I choose the right DCDB for my system?

The selection depends on inverter DC voltage, number of strings, short circuit current, type of inverter, enclosure location, and the protections specified for the project.

6. Can one DCDB be used for residential and commercial projects?

Yes, but the rating, number of strings, enclosure type, and protection configuration must be matched to the specific plant size and application.

7. What maintenance is required for a solar DCDB?

The panel should be checked for tight terminations, healthy surge protection devices, fuse continuity, clean enclosure condition, and safe isolation before service work.

8. Can GEESYS help with DCDB sizing and quotation?

Yes. Share plant capacity, inverter details, string count, system voltage, and installation environment, and GEESYS can recommend a suitable DCDB configuration.
