Frequently Asked Questions

Do you use genuine parts?

Yes. As certified installers for Must, we supply manufacturer-approved parts ensuring safety, reliability, and long-term performance for your solar inverter and battery system.

Repair vs. Replace?

If repair costs exceed 60% of a new unit, we recommend upgrading to a modern high-capacity inverter for better efficiency and longer lifespan.

How long does repair take?

Repair time varies based on the fault type. We provide an estimated timeframe along with your detailed quote to help you plan your power backup needs.

Is there a warranty on repairs?

Yes. All repairs carried out by Sona Solar Zimbabwe come with a warranty covering both parts and workmanship, giving you peace of mind.

Can maintenance prevent future faults?

Absolutely. Regular cleaning, inspection of panels, batteries, and inverters helps prevent common failures and extends the lifespan of your solar system.

Do you offer remote diagnostics?

Yes. For many inverter issues, our technicians can guide you remotely, identify faults quickly, and suggest solutions before a site visit is required.

Are all batteries compatible?
