Probably need more information/context and also maybe some pictures.
When was the CU/DB installed?
When was the solar PV installed?
Was it installed by an accredited MCS approved installer?
Is there battery storage?
Other points of note
Is there Type 2 SPD present?
Is there AC and DC isolation on the PV install?
Type of cable used for array and is it clearly labelled up as DC power
Is there a copy of G98?
Personally I think that Solar PV should be fitted to a fully RCBO populated board (CU/DB) with SPD. Caveat bi-directional. This is as a starting point for Diversity and Earth Leakage.
