If not, does anyone have a suggestion for one that can?** A: No, this meter can not run in reverse. **Q: Does this measure rms or average ac?** A: This energy meter measures rms. **Q: This seller is selling a device that cannot accurately measure power in a us based household. only one "hot" lead is being measured and a house panel** A: So use two and add them together. **Q: How many power meters do i need to monitor: phase 1+ n (110v), phase 2 + n (110v), and phase 1 + phase 2 (220v)?** A: hi it depends on your requirement. You can only use one meter to monitor one of the phase + n . Or you can use three meters to monitor each phase + n . ## Frequently Bought Together - KETOTEK Single Phase Energy Meter Din Rail Electricity Usage Monitor AC 40-300V 100A Voltmeter Ammeter Watt Kwh Frequency Power Meter Built-in CT 110V - smseace Distribution Protection Box, ABS Plastic Transparent Cover Waterproof Distribution Box IP65, for Indoor Wall Circuit Breaker (5 Way) - Chtaixi AC Miniature Circuit Breaker, 32 Amp 120V/240V 2 Pole DIN Rail Mount Circuit Breaker, Thermal Magnetic Trip, Solar AC Disconnect Switch MCB C32 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/475503511-ketotek-energy-meter-ac40-300v-100a-digital-display-led-voltmeter](https://www.desertcart.us/products/475503511-ketotek-energy-meter-ac40-300v-100a-digital-display-led-voltmeter) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-09*
