MK3 works on the system you already own.
The company does not use repair inquiries as a funnel to sell a new solar installation. If diagnosis supports a repair path, MK3 explains the affected equipment and next steps. If a component cannot reasonably be serviced, that limitation should be explained rather than hidden behind a replacement pitch.
Solar repair FAQs
Straight answers, with warranty and repairability determined by the actual equipment and applicable terms.
