At Solar & Storage Live London, PES Solar sat down with Alex Carter, UK & Ireland Sales Director from Heamar, to discuss the critical infrastructure challenges currently facing the battery storage market.

During the interview, Carter addressed a major "headache" in the industry: the shift in cable specifications from copper to aluminum. This transition has led to significantly larger cable sizes, often catching installers off guard. He showcased Heamar’s rapid response to these changes, including the design and manufacture of specialized 500mm lugs specifically for battery storage projects—a solution that was unavailable in the market just weeks ago. Carter emphasized that Heamar acts more as a consultancy than a traditional sales team, urging customers to engage in transparent conversations before installation begins to avoid costly grid connection delays and penalties.
