FranklinWH MAC-R1V1-US Meter Adapter Controller (MAC 1) – Simplified Home Battery InstallationThe FranklinWH MAC-R1V1-US Meter Adapter Controller, also called the FranklinWH MAC 1, is a compact and intelligent meter socket adapter controller designed to make installing FranklinWH home battery storage systems dramatically easier and more affordable — especially in homes with meter-main combo panels.By mounting directly between the utility meter and a third-party meter socket adapter (MSA), the MAC eliminates the need for invasive main electrical panel upgrades, extensive rewiring, or adding sub-panels. This innovative solution can reduce typical installation time from several hours to as little as 20 minutes, significantly lowering labor costs and project complexity for solar storage retrofits.Key Features & Benefits Ultra-Fast & Non-Invasive Installation — Avoids panel modifications and utility red tape common with traditional battery backups. Whole-Home Energy Management — Serves as the central gateway for seamless grid interaction, automatic whole-home backup during outages, real-time metering, and intelligent control of solar, battery, and loads. Seamless Compatibility — Works perfectly with FranklinWH aPower 2, aPower S, and aHub systems. Low Power & Reliable Design — Fanless operation with only 7W consumption, Type 3R enclosure for indoor/outdoor use, and a robust 15-year warranty. Advanced Monitoring — Supports split CT for accurate AC-coupled solar generation measurement (CT sold separately – SKU: ACCY-CT200V2-US).Technical Specifications Model: MAC-R1V1-US Rated AC Voltage: 208/240 Vac (operating range 183–264 Vac) Power Consumption: 7 W Communications: CAN, RS485, Ethernet, WiFi, 4G, Bluetooth Enclosure Rating: Type 3R (indoor/outdoor) Dimensions: 8.4 in (W) × 11.7 in (H) × 3.3 in (D) Weight: 3.3 lbs (1.5 kg) Mounting: Wall mount with ¾” conduit compatibility Operating Temperature: -4°F to 122°F (-20°C to 50°C) Certifications: UL 1741, UL 1741 PCS, IEEE 1547, CSA C22.2, FCC Part 15 Class BWho It’s ForThe FranklinWH MAC-R1V1-US is ideal for homeowners and installers dealing with challenging combo panels, retrofit solar storage projects, or any situation where minimizing disruption and installation costs is critical.
