See Exactly What Your Home Draws

See Exactly What Your Home Draws

The biggest trap in going off-grid is guessing your consumption. You size a battery bank based on estimates, then find out your well pump and refrigerator spike harder than you planned. The CT-200-SPLIT eliminates that guesswork by feeding real-time consumption data into your Envoy-S gateway and Enphase Enlighten dashboard. You see exactly what your home pulls — by the minute, by the circuit. This is the kind of component we vet before stocking: it integrates directly with the Enphase ecosystem, no protocol mismatches, no compatibility headaches. Off Grid Vault carries it because it works within the architecture, not against it.

Snap-On Install Without Rewiring Your Panel

Snap-On Install Without Rewiring Your Panel

The split-core design means you open the transformer, clip it around your existing service conductor, and close it. No disconnecting wires, no pulling breakers, no calling an electrician for a multi-hour job. For a homesteader or cabin builder who is already hands-on with their system, this is how monitoring accessories should work. The CT-200-SPLIT is rated for installation indoors or outdoors, so whether your main panel is in a conditioned utility room or mounted on an exterior wall, its weatherproof build handles the environment. Enphase backs it with a five-year warranty, which tells you they expect it to last well beyond that in field-tested conditions.

Revenue-Grade Data Through Enphase Enlighten

Revenue-Grade Data Through Enphase Enlighten

This is not a ballpark estimator. The CT-200-SPLIT delivers revenue-grade metering accuracy to the Enphase Enlighten platform, the same standard used for production reporting. You get bidirectional communication through the Envoy-S gateway, meaning firmware updates and configuration changes happen remotely — no truck roll, no site visit. The Installer Toolkit mobile app handles initial setup. For anyone who has spent time on DIYsolarforum.com comparing monitoring setups, this is the Enphase-native path: no third-party integrations, no data lag, no parsing mismatched CSV exports. Your consumption data lives right next to your production data in one dashboard.

Compatibility Check

Confirm your system is ready for the CT-200-SPLIT before ordering.

  • Requires Enphase Envoy-S communications gateway for operation

“Added this to my Envoy-S setup last month. Before, I could see what my panels were producing but had no idea what the house was actually pulling. Now I can see exactly when the well pump kicks on and how much the fridge draws overnight. Made me realize I needed another 5 kWh of battery capacity. Worth every penny for the visibility alone.”
