This is a 200 Amp current transformer (CT) from Sol-Ark, used to monitor current flow so your inverter system can accurately track energy production, consumption, or grid usage. It's for Sol-Ark system owners and installers who need accurate metering at the panel or service entrance.
A current transformer is a small but critical link in your monitoring chain — it's what lets your Sol-Ark inverter "see" how much current is moving through a given conductor. Accurate CT sizing and installation prevent skewed readings that can throw off load calculations, battery charge/discharge logic, or grid-export data. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
- Rated for 200 Amp continuous monitoring applications.
- Designed for use with Sol-Ark inverter systems.
- NOT rated to exceed 200A continuous draw — do not install on services or feeders exceeding this rating.
- Compatibility with non-Sol-Ark inverter brands is not confirmed — [NEEDS VERIFICATION].
- Detailed voltage rating, wire gauge for CT leads, and terminal/lug sizing were not provided — [NEEDS VERIFICATION].
CT orientation and polarity are common sources of field errors — install the CT backwards or on the wrong conductor, and your inverter will log negative or inverted current values, throwing off battery management logic and export metering. Confirm correct orientation (line side vs. load side, and directional arrow if marked) before closing up the enclosure, and prevent long-term reporting drift and false fault codes downstream. Validate current flow direction and magnitude with a clamp meter or multimeter before finalizing the install. This isn't just good practice — accurate CT installation is part of maintaining code-compliant metering per NEC guidance on current-sensing devices in service equipment.
- Manufactured by Sol-Ark for use in ESS and inverter monitoring applications.
- Compact CT design intended for standard panel or service-entrance installation.
- Sized specifically for 200A applications — not a universal, field-adjustable CT.
- Supports accurate current sensing needed for reliable inverter reporting and control logic.

FAQ
What amperage is this current transformer rated for?
This CT is rated for 200 Amps.
Will this CT work with any Sol-Ark inverter?
It is designed for Sol-Ark systems. Confirm your exact inverter model's CT input requirements before ordering, since not all details on compatible firmware or wiring configurations are specified here.
Can I use this CT on a service rated above 200A?
No. This CT is not rated to exceed 200A continuous draw. Using it on a higher-rated service risks inaccurate readings and potential damage to the CT.
Does this CT include a UL listing or NEC ampacity documentation?
Specific UL listing and NEC documentation for this CT were not provided in the source data. Refer to the manufacturer's documentation in the Resources tab for full compliance details.
Warranty & Registration: Manufacturer warranty terms for this CT were not provided in the source data. Please refer to the "Resources (System Manuals and Warranty)" Tab above on this page for official warranty documentation and registration instructions.
