Arrays also go offline for telemetry reasons when broadband providers like O2 or Vodafone do things to transmitters, or a construction crane get hoisted up right in line with the building. Even heavy rain can mess up telemetry.
Sometimes tenants damage or interfere with meters and inverters, and when electricians do work in the properties they will turn off the PV for safety reasons – but forget to turn it back on.
In these situations we are not a passive view monitoring service. We continually liaise with our clients to identify issues and come up with solutions. We systematically analyse the data (Energence Analystics) and feedback findings to our clients.
