A Catch-22 in the PV Connector Industry?
02/23/11 - Remke Energy
PV connectors are part of a system, and how well they connect and disconnect along with the ease of assembly & installation is important to installers. Electrical standards for PV connectors have been established through the National Electric Code (NEC) and UL. However no design and/or contact standards exist. The ‘defacto’ standard has not been uniformly accepted by manufacturers. The need for compatibility and interchangeability is clear.

Parallel Solar Technology
02/01/11 - Michael Lamb
Our Parallel Solar approach handles voltage management at the module level, using a DC-to-DC converter (the vBoost) to boost each module’s output. So the array has a high-voltage bus that will never exceed its set voltage as it feeds the central inverter. This allows you to connect the modules in parallel rather than series.
