Solar CT Clamp

    Solar & EVs require data communications. Some chargers such as the Ohme require a CT clamp that measure the total current being drawn, then limits the charging to keep the maximum current below typically 100A. This generally requires a CAT5 or CAT6 cable running from the car charger to the fuse box. Shown below 2 x CT clamps one for the Solis Solar Inverter and another for the Ohme charger.
  Some rearranging of fuse box/s are required to stop the Ohme charger draining the house battery when Octopus Intelligent go trigger charging outside the cheap rate time window.
   The new arrangement on the left allows the Ohme CT clamp to "see" the full load on the main fuse. The only draw back is the Inverter CT clamp only see's the the load on the main fuse box so the data logged by the inverter is incomplete (not a issue). This has fully solved house battery draining problems.
