Solar Inverter not working?

Often your Inverter is the first place anyone would look for a fault with your Solar PV system. RB Grant have experience with a number of different manufacturers and are approved to replace inverters under warranty claims. Do you have an error code on your inverter? The inverter may generates an error code which can help us diagnose the issue. We would visit and find out the exact issue with the inverter. Under warranty claims we would contact the manufacturer on your behalf and arrange everything for you. Most inverters carry a 5 to 10 year warranty and can be replaced within a week. Warranties can be extended by 5-10 years and should be registered with manufacturer.

Solar Panels are damaged?

One of the most challenging faults to diagnose in a solar PV system is a defective panel. Just one faulty panel can significantly reduce—or even stop—your system from generating electricity. At RB Grant, we carefully remove all panels from the roof and carry out a series of tests to identify the issue. Once the faulty panel is found, we’ll register the fault with the manufacturer and assist you in making a warranty claim. With years of experience working closely with distributors and manufacturers, we ensure warranties are honoured.

Installer No Longer in Business? We Can Help

If your original solar PV installer is no longer trading, don’t worry. Once we identify the fault, you may still be able to claim under warranty or insurance. Most repairs we carry out don’t cost the owner anything. Under the MCS scheme, all installers must register systems and provide insurance details. If your warranty has expired, we’ll find the most cost-effective solution to get your system back up and running. As MCS-certified contractors, we maintain industry standards and help protect your Feed-in Tariff (FIT).

Battery Not Charging?

There are several reasons your battery may not be charging.

• Existing customers: We can check your system remotely via the monitoring portal.
• New customers: We can request access to your portal or arrange a site visit to diagnose the issue.

How to Check Your Solar Panels Are Working

Here are some helpful tips to ensure your system is functioning properly:

• Check your inverter for generation data and fault codes.
• Monitor your generation meter regularly and compare with expected monthly values.
• Search online for solutions to any inverter fault codes.
• Ensure your panels are clean and free from debris.
• Inspect for loose cables under the panels.
• If your generation meter is blank, it could be due to a tripped MCB.

How Often Should Solar Panels Be Serviced?

There’s no fixed interval for servicing solar panels. Instead, monitor your generation meter and compare output with previous years. If you notice a sharp drop in performance, contact an approved engineer.
Regular checks should include:

• Cleanliness and physical condition of panels.
• Inverter status and fault indicators.
• Electrical installation inspection at least every 10 years.

Moved Into a New Home with Solar Panels?

We highly recommend having the system inspected. Over the past 15 years, safety standards have evolved, and the industry has seen its share of rogue traders. A professional check ensures your system is safe, efficient, and compliant.
