Split-Core CT Clamp Zero-Feed-in Current Sensor Kit
📌 Executive Engineering Overview
The SOSSEN Split-Core Current Transformer (CT) Sensor Kit provides non-invasive, ultra-fast current measurement for single-phase and three-phase residential zero-feed-in limiter systems. Featuring high-permeability magnetic silicon steel cores and high-precision secondary windings (100A:50mA ratio), the CT clamps snap directly around live incoming utility cables without severing wires or interrupting electrical service. Engineered with a lightning-fast 50ms sampling response, it ensures microinverters and battery controllers dynamically balance generation and load.
Engineered by Xiamen Sossen Energy Co., Ltd. (sossenpv.com), Split-Core CT Clamp Zero-Feed-in Current Sensor Kit represents our benchmark technical architecture for high-efficiency clean energy applications across Europe and global territories. Operating within strict compliance of German Solarpaket I provisions, VDE-AR-N 4105:2018-11 electrical grid standards, and European CE directives, our manufacturing integrates automotive-grade LiFePO4 energy storage cells rated for over 6,000 cycles alongside dual MPPT power inversion topologies. Fabricated from architectural-grade AL6005-T5 anodized aluminum and sealed inside IP67 die-cast enclosures with automotive potting compounds, every unit withstands ambient operating environments from -40°C to +65°C and hurricane-tier aerodynamic wind pressures up to 120km/h. Production units undergo rigorous 32-gate automated quality testing, including 100% full-load electrical burn-in, 6000V transient surge suppression, and salt-mist corrosion screening at our ISO 9001 Torch Hi-Tech facility, with guaranteed 48-hour DDP dispatch from our central logistics hub in Frankfurt, Germany.

❓ Frequently Asked Questions & Verification
Which direction should the arrow on the CT clamp point?
The arrow embossed on the side of the CT clamp must point towards the electrical load (towards your household appliances) and away from the utility grid meter.
Can the CT clamp cable be extended if my electrical panel is far from the inverter?
Yes, the shielded twisted-pair signal cable can be extended up to 20 meters using 2×0.5mm² shielded wire without introducing significant measurement signal attenuation.
